Advantages And Disadvantages Of Dyes
1)Low water consumption and dyeing time:–
With increasing concern of the energy consumption environmental issues, machines should have made with even lower M:L ratios (lower water
requirements for processing and a reduction in the amount of efп¬‚uent generated) with water recovery options and energy (heat) reuse systems. It was
expected that machines like 'Beam Jigger' which is a combination of autoclave and jigger machine, will reduce the dyeing time about 50%, with a
similar reduction in water and energy consumption. Electronic equipment used for automation and controlling in dyeing machines. Brazzoli of Italy
developed beam jigger machine. This open–width batch dyeing machine was a combination of autoclave and jigger. It decreases the dyeing time about
40–50% with water consumption about 35% to 40% and also the energy needs, and is the machines which provide optimum interaction between fabric
and liquor, this machine leads to even faster dyeing processes.

For better results and increase the solubility, dispersion stability, levelling and fastness properties of the dyes additional dispersing agents added. These
dispersing agents have a reducing effect on the dye during dyeing process and after dyeing they add to the COD and BOD of the efп¬‚uent. To
overcome these types of environmental concerns, DyStar introduced a range of 'Green' disperse dyes under its econп¬Ѓdence program which have
ecofriendly chemicals. The issues caused by the use of dispersing agents is being settled with the invention of disperse dyes having temporarily
solubilizing groups. Another way of eliminating the use of dispersing agents during dyeing process, is dyeing with microencapsulated

Health Risks Associated With The Additives
You Are What You Eat Do you read the labels on the products you buy? Do you know what is put in the food you consume? There are many health
risks associated with the additives in products. Most Americans are unaware of the risks that are linked with the additives in commonly purchased
products. My daughter was one year old when I realized she was allergic to artificial coloring. One morning we woke up and I made us a toasty
bagel. I topped the warm crunchy bagel with light pink, strawberry, cream cheese. We enjoyed our bagel as we watched Sunday morning cartoons.
Suddenly I noticed her face was as red as a cherry. In a panic I took her to the bathroom to check for other symptoms. She was red from head to toe
with red raised bumps all over. I immediately called the doctor, who advised me to take her to the emergency room. After the doctor examined her
she told us it was a food allergy. I realized she broke out after eating food that contained artificial coloring. Once I started to look at labels, to avoid
buying harmful products, I realized almost everything contained added coloring. Many manufactures over use artificial coloring in the United
States, which can lead to serious health problems. Americans need to become aware of what is added to our food, and ban artificial coloring. How
can we find a solution to a problem, if most of us are UN aware that a problem exists? First, we must find out what is in artificial colors. Artificial

Mineral Soft Inventory
In the months that we have had Mineral Soft, I have logged over way 100 hours linking, tying and correcting the data that is in Mineral Soft. That's not
including the time it took me to create the spreadsheets required for the upload.
In the time, it took me to build out the spreadsheets plus the time it took for the folks at Mineral Soft to upload our data, I could have created all the
data that is in Mineral Soft with the correct ties. It has taken more than 2.5 weeks to create all of the tract allocations for the wells in OEP and OMR,
so that we can see the revenue associated with each acquisition. It was my understanding that things like this were being done when I sent over the
spreadsheets.

Not to mention, the random wells that OEP or OMR doesn't even own. Wells like the one below (Mandaree 4–15H) were peppered throughout both
entities. And I couldn't find them on the Asset Tracker. Nor in the county records could I find where we bought the interest in that Section, Township
and Range combination. Did you know there is no function to mark a well as Sold? My current work around is adding z– to the first part of well name.
As the wells usually sort by name, adding the z– to the beginning pushes the sold wells to end of the list.
As for the Acquisitions, the tracts had to be tied and add the location information needed to be entered. If the Notes field was on the upload, the adding
of the location information would have been done at the time of upload, saving me many hours. Instead of having to input the information in Notes
field; actually, having some of the legal description as fields in the Acquisition tab would be wonderful. At least, having the County and State as a field
in the Acquisition area would be helpful.
Deeds called for adding the files and the lands covered, in the Notes field, for each and every deed associated with OMR and OEP. Again, having at
least the County & State for where the deed is recorded would be a great help. As it stands, the full legal description for every deed is being entered in
the Notes field. Which is quite time–consuming.

Advantages And Disadvantages Of Membrane Filtration
The increased cost of water consumption and wasteful require treatment process that is integrated with the circuits of water on the ground rather than
as a subsequent treatment (19). From this point of view, membrane filtration offers a potential application. The processes that use membranes offer
exciting possibilities for separation of dyestuffs and dyeing auxiliaries that reduce simultaneously hydrolysed color and biochemical oxygen demand /
chemical oxygen demand of wastewater; generally used to treat effluent reactive dye bath, that could potentially reduce the volume of waste and
recovery simultaneously salt (20). On the other hand, can be separated into two or more components the flow of fluid to its molecular size. The
advantages of membrane filtration are because, it is fast with low space requirement and saturation can be reused. The disadvantage with membrane
filtration method has a limited lifetime before it happens fouling of the membrane and the cost is also excessive (21). The choice of the membrane

Maintain nanofiltration membranes of low molecular weight organic compounds, divalent ions, large monovalent ions, Hydrolyzed reactive dyes and
dyeing of auxiliaries. Harmful effects of high concentrations of dye and salts in dye house outflows have often been reported (33, 34, 35). In most
published studies on dye waste water, the concentration of mineral salts is not more than 20 g / l and the concentration of dye does not exceed 1.5 g / l
(36). In general, the wastewater is reconstituted with only one dye (37), and the volume studied is also low. The treatment of waste water by
nanofiltration is one of the rare applications that are possible for the treatment of solutions with highly concentrated and complex solutions (38). An
important problem is the accumulation of dissolved solids, which eliminates the treated discharge outflows in water currents

Methyl Orange Synthesis Lab Report
Experiment 11B consisted of synthesizing methyl orange, a synthetic dye, and testing this dye's coloring quality and effectiveness as a pH indicator.
Methyl orange is an acid–base indicator. In a pH of greater than 4.4, it becomes a yellow solution with a negatively charged sulfonate ion. When
submerged into a solution with a pH less than 3.2, the dipolar red ion (helianthin) predominates. Methyl orange is a type of azo dye, which is commonly
found in food, fabric, paint, and other brightly colored products. The general structure consists of the N5N functional group sandwiched between two
aromatic species. Azo dyes are brightly colored because of their extensive conjugated system which gives rise to a strong chromophore. The exact color
depends on both the nature of the aromatic group and the substituents. Methyl orange is synthesized through an azo coupling reaction between a
diazonium ion and N,N–dimethylaniline. An electrophilic aromatic substitution causes the positively charged diazonium ion to act as the electrophilic
species. In the first step of azo coupling the diazonium intermediate is synthesized. This process is called diazonation, in which the diazonium
intermediate is formed by the reaction between sulfanilic acid (an aromatic amine) ... Show more content on Helpwriting.net ...

That was scary that to read how they use mutagenic chemical, tris– B8, in children's pajamas. The interesting thing they use this chemical in the U.S,
but not in the Europe. Ames argues that all the permanent hair dyes were mutagenic because they contained aromatic amines, which are often
chemicals. Sadly I dye my hair so often. Sometimes I feel like knowing too much stuff doesn't help. Now every time I go to hair saloon I'll think about
this. Ames argues that when we buy organic foods we are getting 10,000 more toxic chemicals–nature's pesticides–than man–made pesticides. Because

Tie Dye Lab
In this lab, we dyed a white shirt with a modern technique and chemically enhanced dyes. Dyeing fabrics has been an ancient process that has been
used by people since the Neolithic Period, which was a time when humans were just starting to create tools using stone and wood. In 715 BC, wool
dyeing was an actual craft in the booming city of Rome. In 1507, Germany, The Netherlands, and France began the cultivation ofdye plants as an
industry. We can conclude that the craft ofdyeing fabrics has been popular with people for a very long time. "Tie–Dye" is a modern term that was
created in the 1960s when the style became popular. Janis Joplin and John Sebastian were two of the major musicians that brought the style of tie–dye
to the public. Tie–dye

Natural and Synthetic Materials
Textiles are made up from natural or man–made fibres or a combination of both. "Fibres are thin, hair–like structures" (Blair, n.d: online) that are
categorized into two types: long filament fibres and short staple fibres. Natural fibres are usually staple, whilst man–made fibres are filament, with the
exception of silk that comes from a natural source. These raw fibres are spun to produce a long, continuous thread referred to as yarn, which is then
used in a series of methods that include, stitching, knitting and weaving in order to produce a fabric. The content, construction and finish of a fabric
can determine it's aesthetic and functional qualities. This essay will explore the classifications and characteristics of fibres, yarns and ... Show more

Its desirability and expensive price has prompted cheaper man–made imitations. (Udale, 2008)(IYNF, 2009)
"Man–made fibres account for 68% of fibres used worldwide" (CRFS, 2010: online). In the textile industry, man–made fibres are categorized into two
main types: cellulosic polymers and non–cellulosic polymers. Cellulosic polymers are derived from the cellulose extracted from natural sources, such
as plants and trees. The cellulose is then chemically treated to produce fibres such as rayon, acetate and triacetate. Non–cellulosic polymers are those
that are produced synthetically from different chemical compounds in order to produce fibres such as nylon, polyester and acrylic. (Udale, 2008)
Often referred to as artificial silk because of its silk–like aesthetic, rayon was one of the first man–made fabrics to be developed having been in
production since 1885 (Udale, 2008). Constructed from the cellulose of wood pulp, it was made to "simulate natural fibres as well as to provide
characteristics of its own" (Corbman, 1983: p.9). Like cotton, it is soft, comfortable and versatile; it blends well with other fibres, and is often used
for evening gowns as an alternative to silk because of its good drape. It is also a highly absorbent material that can be dyed easily. The durability of
rayon is fairly low, it is easily damaged through abrasion and can shrink when washed, prompting dry clean aftercare instructions. (Swicol, 2010).

My Most Unforgettable Week Of My Life
POW! I dive left to go for the save. The game had just ended and we were now in the penalty shootout. I had to make so many saves in the game to
get us to a PK shootout. Back in March, my parents signed me up for the soccer camp with a friend. Last year my parents won a ticket for the
soccer camp, at first I did not want to go but since the camp was full and there were no other tickets I had to go so I did. After the first two days I
really liked the camp, by the end of it I realized that it would have been more fun with a friend. This year we got a friend that could go to it this
time. There were supposed to be three of us, but one of the friend's parent forgot to sign their kid into the camp. This was my most unforgettable
week of my life because this was just such a good camp, plus I got one of my highlights of my goalie career to me. The camp that I went to was at
Dail soccer/track complex at NC State University. It had a baseball field right next to it with a camp going on for softball. It also took place on the
other two fields across the street, yet there is a tunnel underneath the street that we took. For the games for overtime it did not work the same as
normal we went straight to the penalty shootout, instead of having two overtime periods. This week happened to me because my parents were
able to sign me up for the camp. My parents learned about the camp from last year. They had won a ticket into the camp and since it was sold out
my parents looked at the web page for it to see what it was about and thought I would enjoy it, so I went to it. On the first day of camp we went and
filled everything out so I could have fun and any insurance for the camp, I don't know I went to the camp to have fun I did not pay any attention to
the signing in anything else to start the camp. After that, I went and found my group I was supposed to be in which turned out to be the second
goalie group. In the second goalie group, we were more like a group of people that have some problems with ourselves. Most of the people in our
group would talk when our coach talked or wanted them to pay attention. Then there were the other people, like me, in the group who wanted to get as
far as possible in training and wanted to

Food Additives And Its Effects On The Modern World
People who live in the modern world can readily enjoy a variety of delicious foods such as hamburgers, macaroni and cheese, and even sushi rolls.
These meals, in many cases, do not require people to spend much time to prepare them. Instead of time–consuming preparation, people only have to
mix up all packed ingredients and then put them into a microwave. In respect of sushi roles, they are usually sold after every cooking process is
finished. In other words, all consumers have to do is just open up the package. Because these prepared food products are processed in big factories,
most people who prefer to eat these dishes do not seem to know how to cook them from scratch. However, during industrial manufacturing, ingredients
that are usually not found in the house kitchen are used frequentlyв€’food additives. Food additives are eatable chemicals which make food appetizing
and keep it fresh. The final goal to utilize these chemicals is to save production cost. For instance, strawberry gummies people eat are usually flavored
with food additives to mimic "strawberrish" smell, taste, and color. Manufacturers paint gummies with red, orange, blue, and green dye because the cost
of food dyes is incredibly cheaper than the cost of real fruit to flavor the same amount of gummies. Alternatively, orange juice is another typical
example of food products with food additives. The amount of juice squeezed from one orange is really small. It cannot fill even a small cup.
Therefore, juice

Suddenly I could not take my eyes off what was in front of me. Hammocks were hung from trees and even hung from car mirrors. There were hippies
sleeping in, and on their cars. I saw people cooking on small grills, selling food right from the trunk of their car. A simple sign that read, "Fish
tacos." I was memorized by all the booths that lined the entrances of Legend Valley. People sold paintings, jewelry, tie dyed bags, shirts, skirts, and
head bands. I made my dad stop at one booth because I saw a dress that I absolutely loved. It was priced at $30. When I paid for my purchase the
woman expressed how grateful she was that I was buying her clothing because that is how she made a living. She told me the story of how she lives
in her car, and travels to these festivals. I felt sad for a brief moment until I realized this was her calling and she was truly happy. It inspired me to
appreciate the little things that surround me.
Also there were hundreds of tents on the opposite side of our camper, each one a bright color with some article of tie dye draped over it. In front of
the tents sat chairs, empty. I asked my dad, "Where is everyone?" He just chuckled and said, "You'll see them when we attend the concert."
When we made our way back to the camper, there was a car full of young modern day hippies parking next to us. My eyes wondered to each

In general all dyes were natural substances, derived mainly from plants and animals in ancient days. In the 19th century natural dyes obtained from the
plants and animal parts were the main colourants for fabrics. The natural dyes present in plants and animals [1] impart colour to the fabric materials.
The awareness about the ecology and environment is increased nowadays. There is a greater need today to revive the importance of natural dye and
dyeing techniques as an alternative to synthetic dyes. In the present scenario, the interest in the use of natural dyes has been growing rapidly due to
severe environmental standards resulted in avoiding the synthetic dyes, causing ill effects. These standards are framed by many countries in response

Tie–dye is one of the oldest forms of fabric manipulation and design"(Crazyfads.com). Tie–dyeing is based on the traditional art of folding or tying
fabric to create resists that stop the dye from being absorbed into parts of the fabric, thereby forming unique patterns of color. Often people use tie–dye
to create a design on white fabric During the 60's, the hippies' revival of old ethnic crafts resurrected the art and put a new spin on tie–dye. "The
hippie' tie–dye was no subtle handicraft–they tie–dyed with several colors, layering one on top of the other for wild bursts of color and crazy visual
trips. Hearts, peace signs, bulls eyes–anything could be done with a little creativity. Tie–dyeing became the ultimate sign of the times"( Crazyfads.com

were kids. Parents passed down this knowledge by turning t–shirts, and other clothing into colorful panels of fun. Though it wasn't a popular thing ,
tie–dye was a style of choice for 60's relic and people who just wanted a little fun in their

In 1964, at the Royal Academy, one of the paintings he sent in was Morning and Evening: Chelsea Reach (RA726), this was his last work shown
there. Furthermore, Harry Parr, in the tradition of pottery figure making, had staked his claim by his superlative craftsmanship, and his work in the
genre, was recognized by the knowledgeable figure–collector. However, he made even fewer thrown vessels than his meagre output of figurative
work. It would appear that Parr and his work are under–researched or ignored by the modern commentator of studio pottery, and a greater effort than
this author can provide is required to restore him to his position in the vanguard of the early twentieth century studio pottery movement, now is the
time for further research into the life and work of this much neglected artist. In his final years, his youngest daughter Janet Parr cared for him at the

The soft fabric spray is formulated to absorb into light–colored fabric, but it stays soft to the touch. My t–shirt doesn't feel any different than it did
before I spray painted it. It's still a soft t–shirt, but now it's fun instead of boring. After using Simply Spray fabric dye on your t–shirt or other clothing,
it's advisable to wait at least 72 hours before washing it in the washing machine. I like to either soak mine in the sink with a gentle detergent or use the
delicate setting on my washing machine. I do that to ensure my t–shirt stays soft, supple, and vibrant for a long time. Simply Spray is a durable,
fade–resistant formula, so there is no need to be picky about its care like me, but I recommend it if you're going to go to the trouble of creating
something so special. The time I saved on creating this tie–dyed tee using Simply Spray is enough for me to keep using it for all my arts and crafts

the synthetic dyes are easier to use, cheap and widely produced and available, the usage of natural dyes continues on decreasing since the 19th century
(Samanta, 2009).
Natural dyes produce very uncommon, soothing and soft shades as compared to synthetic dyes. It is known that natural dyes produce unusual colors
that appear to be harmonizing. On the other hand, synthetic dyes are widely available at a reasonable price and produce a variety of colors; these

Let the dye bath simmer for about an hour. Turmeric dye is famous in
India because for them yellow is a sacred color. They said clothes dyed with turmeric are pure.
Dyeing Process
One of the key factors in the trading of successful textile products is the dyeing process. This helps to beautify and enhance the fabric. Usually the
consumers look to some basic characteristics of product such as good fixation. This is to ensure to maintain the properties, the substances that give
color to fabric must contain high affinity, resistance to fading and be economically feasible. First, drain the vinegar mixture then pour the turmeric dye
over the fabric into the pot; heat over medium–low flame. As the fabric left longer in the turmeric dye, the more vibrant the color. Then afterwards,
wash the fabric.
Rinse Well the Cloth Then Dry the Fabric.
Drain the turmeric dye then rinse the cloth under running water to remove excess dye. Remember the dye can stain porcelain so rinse the cloth on a
stainless steel sink or even at an outdoor tap. Then let the fabric dry overnight to see better

Personal Narrative: Katy Perry
I was a massive fan of the singer, Katy Perry throughout my childhood, especially at the age of 10. The radio always seemed to crank up whenever
her songs came on. I searched up all her music videos on Youtube to watch them for hours and even started a two member fan club with my sister,
Kaitlyn. Once her album "Teenage Dream" came out, I took my Katy Perry obsession to an extreme. I spent my 2012 summer days watching and
listening to her music videos at home, as if it was my first time seeing that music video each time I viewed it. One day, I stumbled upon the music video
for her song, "Wide Awake" and came up with an idea. Katy Perry has purple hair in the music video so I believed that if I dyed my hair, it would be

In that same moment, I heard the crunching and rumbling of gravel as my mom pulled up into our driveway to bring us lunch to eat. I covered the
stain with a blanket from the couch and ran to the door to greet my mom. I combed out my smooth, velvety feeling hair with my fingers as I
nervously conversed with my mom. My plan was made to be foolproof, but once she reached the living room, she saw the blanket on the ground and
picked it up to put back on the couch.
My mother's eyes filled with fire, her stern face turned a light red, "What is this from?"
My shoulders tensed up, I felt my heart swiftly drop to my stomach, "It was me! I was dyeing my hair and I forgot it was still in my hair when I was
laying on the ground. I'm sorry!"
With a slightly more gentle tone, my mother said, "It's okay. We planned on deep cleaning the carpets soon anyways. However, since you didn't listen
to me and tried to dye your hair anyways, I'm taking away your internet privileges for a week and you will be helping your dad and I clean the carpets."
My shoulders sank back down and relaxed. A wave of relief washed over me when I realized my mother wasn't as mad as I thought she would be.
However, I was a bit bummed when I wasn't allowed to watch Katy Perry music videos for a week. Needless to say, I learned my lesson after that and
never attempted to dye my hair by myself

Abstract
In this paper, an artificial food dye will be made to mimic the color of Full Throttle. To determine what food dye are needed, Full Throttle will be put
through a spectrometer to determine what wavelengths are absorbed. Specific wavelengths absorbed will correspond to specific colors absorbed. It
was determined that yellow 5 and yellow 6 will be used to make our artificial food dye to mimic Full Throttle. Using Beer's Law, it was determined
that a concentration of 0.0000236 moles of Yellow 5 and a concentration of 0.0001494 moles of yellow 6. Using our line of best fit from the
absorption graphs, it was determined ... Show more content on Helpwriting.net ...
When making the absorption graphs for the yellow 5 and yellow 6, the lines of best fit were giving numbers that were extremely small. After help
from the TA, it was found that our concentrations used where twice as small of a concentration compared to what was actually used for Full Throttle.
To correct this the molarity's were multiplied by ВЅ. For example when finding the x value in our equation y=2.044x+0.2067 the answer is x = 7.28–5
moles. To correct this, that number is multiplied by 0.5 to get the correct value of 3.64*10^–5. This new number is what was used in the equation
c1v1=c2v2. After the solution was made to mimic Full Throttle it was discovered that the beverage only had one food dye. The experiment was
intended to have a beverage with two food dyes present. To make up for this, orange PowerAde was used and the experiment was repeated for
orange PowerAde. The solution was made for the orange PowerAde and its absorption graph was compared to that of the diluted orange PowerAde
solution. Comparing the two graphs, have the same peaks although these peaks are at different absorption levels. Since the two graphs have the same
peaks it is safe to assume that the same food dyes are present in both solutions. It is important to note that there are two peaks in each graph despite
only seeing one peak. This is because both peaks are located so close to each other that they merge as one overall peak. When comparing the two

Looking For A Creative Project
Are you looking for a creative project that 's fun, easy and fairly quick? Tie dying is a great activity for the whole family! The wonderful thing about
tie dye is that you can 't really mess it up and anyone can do it. Here are the things you 'll need to gather before getting started:
Fabric to dye. You can dye t–shirts, bandannas, shorts, socks, underwear...whatever you 'd like, as long as your fabric is 100% cotton, rayon, or other
natural fiber, otherwise the dye won 't hold. Inexpensive cotton t–shirts are perfect for beginners. You should pre–wash them to remove any finishes on
the cloth that might interfere with the dying process. Dye to color your fabric. The three primary colors for tie dye are fuchsia, yellow and turquoise.
Other colors can be achieved by mixing two or three of these together, for example, fuchsia and yellow will give you orange. You can buy individual
supplies but if this is your first time dying, I recommend a tie dye kit. You can get them in most stores that offer craft supplies or order them online. I
've used the Tulip Dye Kits for birthday parties and the shirts turned out beautifully. Mydyes of choice however, are Procion MX dyes. You can order
kits online through stores such as Dharma Trading Company. I do not recommend using RIT dyes. I 've found them to be very messy and the colors
run and fade quickly. Soda ash to pre–soak your shirts in. Some kits have it included. If not, you can find soda ash, (aka sodium carbonate); at

Advantages And Disadvantages Of Chemical Dyes
Natural dyeing has the advantage of having high diversity of rich and complex colours. The advantage that different natural colours go well together
and rarely clash works in favour of merchant. The results that come out after using natural dyes are even more vibrant.
The disadvantage is that natural colours require to be taken in large quantities when compared with chemical dyes. Furthermore, it also takes a longer
time which is not the same case with chemical dyes. The cost of the natural is significantly higher; however, time is required if one is growing their
own plant dyes.

Food Dyes : History And History Of Food Dyes
Food Dyes
In the late eighteenth century food manufacturers started to use synthetic dyes as a marketing strategy to sell more food and earn more money. The
reason that they make a large amount of money selling their food is because the dye covers the natural color of the food. People don't find the natural
color of the product as appetizing as to when it contains the synthetic dye. They would change the color of the product because that was the only factor
that they could control other than smell, texture, etc.
First we will start off with a brief history about food dyes. Before synthetic dyes Egyptians used saffron, indigo and cochineal as their main source
to color their food. These ingredients were derived from plants and organic minerals and every ingredient was used to color something specific. But
after many years of using these natural ingredients the first synthetic dye was created. In an article written by Ai Hisano he states, "In 1856, British
chemish William Henry Perkin succeeded in processing the first synthetic dye, mauve," (par.11). Mauve is a pale purple and it was named that
because it was named after the mallow flower. Color is a powerful communication tool used to appeal to the eye of the customer. These colors attract
the children in wanting their parents to buy them the product and this increases the sales for that company. When buying food the customer always
looks at the appearance of the product and it is a fact that about 85% of the customers

Dyeing Studies of Wool Fibers with Madder
In this study, the dyeing behavior of wool fabrics with madder has been studied. Also, the effect of different mordants (potassium dichromate, stannous
chloride, alum, ferrous sulphate, lime, copper (I, II) sulphate, cobalt chloride, and nickel chloride) as well as three mordanting procedures namely pre–,
meta– and post–mordanting on color characteristics of the dyed samples has been investigated. The adsorption isotherm of madder on wool fibers was
found to follow Freundlich type of adsorption. The addition of salt and acid (pH 4.5) to the dyebath resulted in an increase of adsorption. In relation to
mordanting tests, the use of different mordants and mordanting procedures gave various color characteristics on dyed wool fabrics. The results showed
that all the dyed samples, mordanted and unmordanted, were in the first quadrant of CIEL*a*b* color space. Mordants such as potassium dichromate,
ferrous sulphate and copper (I, II) sulphate led to the darker and lower chromaticity compared to unmordanted dyed sample while mordants stannous
chloride, alum resulted in the lighter and higher chromaticity values. Mordanting with the chlorides of cobalt and nickel showed the minimal color
difference (в€†E) with the unmordanted dyed sample. The fastness properties indicated that in general wash and light fastness of the mordanted
samples were higher than the unmordanted one.
Key words: wool, madder, mordant, fastness properties, natural dye.

Food dyes and prenatal stress given to rats does in fact influence behavior. An experiment conducted on the rats confirmed that the stressed rats during
the last days of pregnancy were more hormonal than the unstressed rats during pregnancy. However, hormonal differences did not vary between the two
groups during non–stress days. The amount of liquid consumed by the rats and the rats' body weight showed no signs of being affected by whether or
not the rats consumed dye or tap water. Scientists found that even though one group of rats were given both stress and food dye, both variables did
not affect one another. The rats that were given dye ingested an average of 1.71 milligrams of each dye per day. During the open field task, scientists
observed that both age and amount of stress of the rats affected the distance travelled. However, stress, age, and amount of dye consumed did not
interact with each other. At the ages of 1.5 months and 13 months, stress on the rats affected both distance travelled and amount of time spent moving,
and at 1.5 months but not 13 months, the amount of dye consumed affected only movement time. At 7 months of age, there was no correlation between

However, 22% of 92 children that are diagnoses with ADHD are wrongly diagnosed (Lilenfield & Arkowitz, 2013). Many of these false diagnoses

Administration (FDA) should ban the use of all synthetic food dyes in food and cosmetics
Food dyes are additives that help to give food and other items a more colorful and appealing look. Originally, food dyes were made out of natural
ingredients such as fruit juice, vegetables, and in some cases, bugs. However, as time went on, other ways to make food dyes were created. Natural
food dyes lead to synthetic coal tar food dyes, and eventually synthetic coal tar food dyes led to petroleum based synthetic food dyes. Synthetic food dye
colors certified for food use are Food Drug and Cosmetic (FD&C) Blue No. 1, FD&C Blue No. 2, Citrus Red No. 2, FD&C Green No. 3, Orange B,
FD&C Red No. 3, FD&C Red No. 40, FD&C Yellow No. 5, and FD&C Yellow No. 6 (Kobylewski, 2010). Using just these nine dyes, there are over
360,000 different color combinations available.

Concerns On Toxicity Of Food Dyes
Concerns on Toxicity of Food Dyes Abstract Food dyes have been a growing topic in the United States ever since the 1970s since they are used in
many of our foods in order to make certain foods more appealing to our senses. In the United States, most artificial/synthetic food dyes are currently
legal. Not all scientists agree on the adverse effects that these food dyes can possibly display. Due to recent studies, the British government has
already banned food dyes in their country by the year 2009. In addition, the European Parliament passed a law that requires a warning on all foods
that do contain food dyes tested after July 20, 2010. Many parents are petitioning against these food dyes. These parents' goal is to make artificial
/synthetic food dyes a large enough concern to be noticed and lead to a ban on these controversial dyes. The ultimate goal of these parents is to
achieve the rules and regulations in which the United Kingdom has accomplished. This paper will look at the concerns of these food dyes that the
parents have. There is much research and controversy over the truth about these food dyes. This paper will be of importance to help bring out the
truth as to why food dyes are even of concern. After much qualitative analysis this paper plans to answer, why are parents so concerned about
artificial/synthetic food dyes in their food? Overview/ Background Food dyes were used all the way back to ancient times. Unlike today, those dyes

This theory was formulated in 1970 and is one of the most recent on the topic of gel electrophoresis. The National Academy of Science states, "The
behavior of macromolecules in gel filtration and gel electrophoresis may be predicted from Ogston's model for random mesh work of fibers. This
model has been generalized to apply to non–spherical molecules and to several gel types. The theory defines conditions for optimal separation and
optimal resolution in gel electrophoresis and gel filtration" (Unified Theory for Gel Electrophoresis and Gel Filtration). There are a few
components that compose a gel electrophoresis chamber. First of all, there is a chamber used to contain the gel. The gel used in my experiment will
be made from agarose. In order to create an electric field, there are positive and negative electrodes attached to a power source. My experiment will
use alligator clips as the electrodes and nine–volt batteries as the power source. A buffer solution, in this case a 1% solution of baking soda,

as curly, kinky, frizzy, natural, or even as afro hair. Growing up I have seen very few people with color their afro hair. Not only in my hometown, but
nearly everywhere I have been to and even in the media. I want to know why dyed straight hair is more common than dyed afro hair. Whether that must
do with the effects hair dye has to natural hair. Or the price and extended effort of taking care of dyed hair. Or even the way hair trends are
portrayed in the media and by celebrities When dyeing darker hair, bleach is needed to lighten the color for the actual hair dye to color the hair.
Bleach is harmful to the hair as it causes dryness and breakage. Natural hair is usually dark and would need to be bleached if it were going to be
dyed, but the last thing it needs is more dryness. From experience, my type of hair dries out easily and needs numerous other products to keep it
moisturized. Hair dye is purely chemical which might affect curl patterns and the overall look of the hair. Convenience stores don't always carry the

By changing the properties of the liquid phase (e.g. concentration, temperature, pH) adsorbed species can be released from the surface and
transferred back into the liquid phase. This reverse process is referred to as desorption. Since adsorption is a surface process, the surface area is a key
quality parameter of adsorbents.
Engineering adsorbents are typically highly porous material with surface area in the range between 102 and 103 m2 /g. Their porosity allows
realizing such large surfaces as internal surfaces constituted by the pore walls. In contrast, the external surface is typically below 1 m2 /g and
therefore of minor relevance. As an example, the external surface of powdered activated carbon with a particle density of 0.6 g/cm3 and a particle
radius of 0.02 mm is only 0.25 m2 /g.
However, adsorption is one of the promising methods to remove the dye pollutants from aqueous system completely. It was, therefore, thought
worthwhile to develop highly efficient and effective adsorbents for the removal of dye from the textile
