Fibres are the basic unit that make up all fabrics. There are two types of fibres - natural fibres obtained from plants and animals like cotton, jute, silk and wool, and man-made fibres obtained from chemicals like nylon, polyester and acrylic. Wool fibre comes from the fleece of sheep and other animals and is obtained from the soft under-hair. These fibres are converted into yarns through processes like carding and spinning, where they are twisted together into longer, thicker strands to make them stronger for weaving fabrics.

1. Natural Fibre
2. Man – Made fibre or Synthetic Fibre
Fiber is the main part of a textile material. All fabric/garments properties and process is directly depends on fiber which contain by the garment.A number of methods are available for characterization of the structural, physical, and chemical properties of fibers. Various methods are used for fiber identification like microscopic methods, solubility, heating and burning method, density and staining etc. End-use property characterization methods often involve use of laboratory techniques which are adapted to simulate actual conditions of average wear on the textile or that can predict performance in end-use.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
Toxic effects of heavy metals : Lead and Arsenicsanjana502982
Heavy metals are naturally occuring metallic chemical elements that have relatively high density, and are toxic at even low concentrations. All toxic metals are termed as heavy metals irrespective of their atomic mass and density, eg. arsenic, lead, mercury, cadmium, thallium, chromium, etc.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
2. What is fabric?
• You all know that food, clothing and shelter
are the three basic needs of life. You eat food
to survive and protect yourself from diseases,
you need a house to live in. Why do you wear
clothes? You wear clothes for protection
against climate, for modesty and beauty, and
also to show status. The material that you use
for clothing is called fabric.
3. • If you go to a shop to buy fabric for
your dress, you would see a variety of
fabrics there. Do you wonder what
these fabrics are made of? How you
get variety in fabrics? Why are some
materials warm, some soft and
others rough? Why do some
materials go bad after washing while
others remain the same?
4. • Do you know what fabrics are made
of? Take a cloth and pull out a thread.
Untwist to loosen this thread. You will
see that it is made up of smaller
threads or hair like strands. Pull out
one of these. This single hair like
strand is called a fibre.
• A fibre is a hair like strand from
which all fabrics are made.
5. Natural Fibres:
• Some fibres are obtained from
natural sources, that is, from plants
and animals. Fibres from such
sources are called natural fibres.
• Some examples of fibres from
natural sources are cotton, Jute,
silk, wool, etc
6. Man-made Fibres:
• The other type of fibres are obtained from
chemical substance. These are called
manmade fibres. They are rayon, polyester,
nylon, acrylic (cashmilon) etc.
7. • Classify the following fibres as man-made and
natural:
• (i) Nylon (ii) Wool (iii) Cotton (iv) Silk
(v) Polyester (vi) Rayon(vii) Acrylic (viii) Jute
8. State whether the following are true
or false and correct the false
statements:
• (i) Fibre is the basic unit of all fabrics.
• (iii) Jute is the outer covering of coconut.
• (iv) Silk is prepared from the stem of a plant.
• (v) Polyester is a natural fibre.
9. Animal fibres
• Wool is obtained from the fleece (hair) of
sheep or yak. Silk fibres come from cocoons
of the silk moth. Do you know which part of
the sheep’s body yields fibres? Are you
aware how these fibres are converted into
the woollen yarn that we buy from the
market to knit sweaters? Do you have any
idea how silk fibres are made into silk, which
is woven into saris?
10. WOOL
• Wool comes from sheep, goat, yak and some
other animals. These wool-yielding animals
bear hair on their body.
• Why do you think these animals bear hair on
their body?
11. Activity
• Feel the hair on your body and arms and those
on your head. Do you find any difference?
Which one seems coarse and which one is
soft?
12. • The hairy skin of the sheep has two types of fibres
that form its fleece: (i) the coarse beard hair,
and(ii) the fine soft under-hair close to the skin.
• The fine hair provide the fibres for making wool.
Some breeds of sheep possess only fine under-hair.
Their parents are specially chosen to give
birth to sheep which have only soft under-hair.
This process of selecting parents for obtaining
special characters in their offspring, such as soft
under hair in sheep is called selective breeding.
13. • The fleece of sheep is not the only source of
wool.
• Wool is also obtained from goat hair. The
under fur of Kashmiri goat is soft. It is woven
into fine shawls called Pashmina shawls.
• The fur (hair) on the body of camels is also
used as wool.
14. Activity
• Collect pictures of animals whose hair is used
as wool. Stick them in your note book.
17. Steps to Commercial Fiber Processing
• Shearing – shaving the hair from the sheeps
body.
• Scouring -the removal of all impurities from
grease wool, using water, detergent, and
sometimes a mild alkali.
• Drying- The amount of water held by the wool
is reduce to below 15%.Moisture in wool is
removed by hot, dry air blown through the
wool prior to being exhausted from the dryer.
18. • Sorting: The hairy skin is sent to a factory
where hair of different textures are separated
or sorted.
• Carding: The woollen fibres are disentangled
and straightned into a continous form.
• Combing, spinning and weaving
19. Yarns
• Do you remember pulling a thread from a cloth
and opening it? Yes, you found hair like fibres.
That thread which was made of fibres is called
yarn. Yarns are made up of a number of fibres
twisted together. Fibres are thin and small and
cannot be made into a fabric directly. So they are
first converted into yarns which are longer,
thicker and stronger. We use these yarns to make
fabrics.
• A yarns is a continuous strand made up of a
number of fibres which are twisted together
20. YARN MAKING
• The process of making yarns from fibres is
called spinning. Here the fibres are not only
twisted but also pulled out or drawn.
• The spinning process helps to hold the fibres
together and makes the yarns strong, smooth
and fine.
• Spinning can be done by using a takli (spindle),
a charkha or a spinning machine.
21. State whether the following are true
or false:
• Yarn is made of a number of fibres.
• Spinning is a process of making fibres.
• Spinning increases the strength of yarns.
• Twisting increases the strength of the yarns.
• Smoothness of a yarn depends on the twisting
of the fibres.
