Function, Uses, Advantage & Dis advantage of Basic Chemicals:-
Acetic Acid:
Page 5 of 19
As we say that disperse dyes enters in the non crystalline region of the polyester at high
temperature, than acetic acid has a great role. we should have to maintain pH 4-5 for dye
fixation. Since our inception, we have been satisfying our global clients offering acetic acid with
molecular formula CH3COOH. Acetic acid offered by us is a clear liquid free from suspended
matter having pungent odor at temperature above crystallization point.
We procure textile acetic acid from reliable sources and are stringently tested at our end for
purity, quality, composition and formulation. Widely used in the textile industry, these acids are
colorless liquid or crystals in appearance. Acetic acid is a weak acid. It is available at different
concentrations. Highly concentrated acetic acid at 98% and above is called glacial acetic acid
because its freezing point range is between 13.3 ºC (98%) and 16.7 ºC (100%). Glacial acetic
acid is flammable. The concentration of acetic acid can easily be determined using acid–base
titration with phenolphthalein as an indicator. The water used should be free from CO2, prepared
by boiling before use
Oxalic Acid: Oxalic Acid also use in textile industry to maintain pH. To develop the color or
printed fabric & to fix the dye on the fabric permanently. Oxalic acid offered by us is the
compound with the chemical formula H2C2O4. This is a dicarboxylic acid and can be well again
described with the formula HOOCCOOH. It acts as a relatively strong organic acid as it is about
3,000 times strong as acetic acid. These are used as a mordant in dyeing processes in the Textile
industry.
Soda Ash: Na2CO3 also use in textile industry to maintain pH. To develop the color or printed
fabric & to fix the dye on the fabric permanently. Sodium carbonate (Na2CO3) is also called soda
ash. In textile wet processes, it is often available in anhydrous form. Its purity can be > 99%
Na2CO3 (58% Na2O). If the concentration of a Na2CO3 solution needs to be determined, a
titrimetric method identical to the ones listed for NaOH in this section can be used.
Na2CO3 is a medium type of alkali compare to NaoH. It use to maintain pH from 8-11.
Sodium Hipochloride: Sodium Hypochlorite is a greenish-yellow liquid commonly referred to
as "Bleach." The chemical formula for Sodium Hypochlorite is NaOCl. Sodium Hypochlorite is
prepared by reacting dilute caustic soda solution with liquid or gaseous chlorine, accompanied by
cooling. In hypochlorite bleaching of textiles, active chlorine is the species measured for the
control of the bleaching process. Iodometry is the method used to determine the content of active
chlorine.
Sodium Hipochloride is the strongest oxidation agent because it capable to giving oxygen at
room temperature.
By using sodium hipochloride bleaching in industry now a days is absolute because of extra
process is required for remove chlorine which is costly. The process of removing of chlorine
called anti chlor treatment. This is the main dis advantage of Sodium Hipochloride bleaching.
Page 6 of 19
Sulphuric Acid: Sulphuric Acid use in textile industry to maintain pH. To develop the color or
printed fabric & to fix the dye on the fabric permanently. It is on of the strongest acid. By use it
we can increased pH rapidly. But it also have some disadvantage. It dissolved cellulose of cotton
& depredate fiber.
Hydrochloric Acid: Hydrochloride acid used in Textile bleaching, Bleaching of cotton fabrics,
Wool scouring (see article),Bleaching of wool, Waste water treatment (see article), Measuring
dissolved oxygen & neutralization of alkali.
Bleaching Agent:
 Hydrogen peroxide:
Hydrogen peroxide is the simplest peroxide and an oxidizer. Hydrogen peroxide is a clear
liquid, slightly more viscous than water. In dilute solution it appears colorless.

Function, Uses, Advantage & Dis advantage of Bleaching Agent:-
Hydrogen peroxide:
Hydrogen peroxide is seen as an environmentally safe alternative to chlorine-based bleaches.
H2O2 can be use for bleaching cotton silk jute. Less water is required for peroxide bleaching. For
bleaching of colored cotton goods peroxide is better than hypochloride.
There is generally no need for through scouring before peroxide bleaching. Peroxide ha excellent
storage stability. It is involves low risk of chemical damage of cotton. The main disadvantage of
peroxide bleaching is peroxide lefy on fabric causes uneven dyeing.
Salt or Electrolytes:
 Glubar salt (Sodium sulfate)
 Common Salt (NaCl)
 Caustic Soda (NaOH)

Function, Uses, Advantage & Dis advantage of Salt:-
The textile substrate and dye molecule, not necessarily should have of homogeneous
characteristics to combine with each other. In such case, we require some catalyst to facilitate
dyeing action on fabric. Salt plays this crucial role of catalyst. Salt has an extremely high affinity
for water. Broadly speaking, Salt is necessary in three ways, firstly, to drive dye into textile
during the dyeing process in textile. Secondly, use of salt leads to maximum exhaustion of dye
molecules during dyeing process in textiles. Thirdly it is used as an electrolyte for migration,
adsorption and fixation of the dyestuff to the cellulose material. Salts plays important role in
reactive dyeing by improving the affinity of the dyestuff towards the fibre and acceleration of the
dyestuff's association and lowering its solubility. Normally, Glauber's salt or common salt/
vacuum salt is used for this purpose. The presence of chlorine ion in the common salt may cause
corrosion of the equipment. Hence, Glauber's salt is always preferred over common salt.
Glauber's salt is a common name for sodium sulfate decahydrate, Na2SO4.10H2O; it occurs as
white or colorless monoclinic crystals. Upon exposure to fairly dry air it effloresces, forming
powdery anhydrous sodium sulfate. Johann Glauber’s was the first to produce the salt (from
Hungarian spring waters). Glauber's salt is water soluble, has a salty, bitter taste, and is
sometimes used in medicine as a mild laxative; it is also widely used in dyeing. Vacuum salt is
the common name of sodium chloride (NaCl).
The salt in the reactive dyeing increases the affinity of the dye towards the Cellulosic substrate.
Salt increases the exhaustion rate of reactive dyestuffs.
As reactive dyestuffs have a lower affinity, more inorganic salt is required when using reactive
dyestuffs in order to accelerate absorption.
Page 8 of 19
While the amount of inorganic salt used varies according to the type of dyestuff used, recently
developed high-fixation dyestuffs with improved affinity allow the amount of inorganic salt to be
reduced.
Due to considerations of effectiveness and cost, both Glauber's salt and common salt (sodium
chloride) are used in dyeing. In terms of their role as an inorganic salt, these two are effectively
the same because of the sodium cation active in both.
Scouring Agent
This is needed to remove the oil , fats etc from the fabric. The term ‘scouring’ applies to the
removal of impurities such as oils, was, gums, soluble impurities and sold dirt commonly found
in textile material and produce a hydrophilic and clean cloth.
To remove natural as well as added impurities of essentially hydrophobic character as
completely as possible.
To increase absorbency of textile material
To leave the fabric in a highly hydrophilic condition without undergoing chemical or physical
damage significantly.

In the scouring process the cotton cellulose material is treated with a solution containing alkali (
soda ash and caustic soda), an anionic and/or nonionic detergent, a wetting agent, a complexing
and sequestering for the removal of metal ions and polyacrylates or polyphosphonates as special
surfactant free dispersing agents, at high temperature.The scouring operation was conventionally
Page 9 of 19
done in kiermachines and hence the process was called kier boiling, but now a days the scouring
is done mostly in the dyeing machines itself as a part of combined or single operation such as
scouring and bleaching. Saponification of fats into water soluble soap and water miscible
glycerin under alkaline conditions. Hydrolysis of proteins into water soluble degradation
products. Dissolution of amino compounds. Solubilising of pectose and pectins by converting
into soluble salts. Dissolution and extraction of mineral matter. Emulsification and solubilisation
of natural oils and waxes. Removal and dispersion of dirt particles and kitty by the action of
alkali and detergent. The material after scouring is more absorbent , free from natural impurities
and coloring matter.This treatment can be carried out on filaments, yarns and fabrics.
Anti foaming agent:
Used to prevent formation of foam during stirring or during dyeing in one bath. Where the
present and persistence of foam is a nuisance, defoaming agents or antifoams are used. For
maximum efficiency deform should be added to baths when necessary. There two groups of
defoamers one that is water-soluble surfactants and other is water insoluble emulsions of
silicones of organic-based the most effective defoamers are where the water-soluble compounds
are used as vehicles for silicones of organic emulsions.

4. Perfect acid resistance, as nyloon soften anti-wrinkle agent when dyeing.
5. Dipersing and levelling property, fluffy crease-resistance agent for terylene when dyeing.
Wet processing and dye-bath lubricants are used in any operation in which rope marks, creases,
crows feet buffing, abrasion can occur on textiles. In low liquor ratios, full-loaded winches and
jets when heavy materials re processed, fiber lubricant is essential. The basic requirement is that
Page 10 of 19
is it should from a thin uniform protective coating around the fiber to lower the surface friction
and flexural rigidity, thus minimizing the formation of durable creases during high temperature
processing. The most suitable lubricant should have the properties so that it helps to emulsify, it
does not undergo phase separation with extreme changes in pH and temperature, e.g. it is stable
in high temperature and over a wide range of pH; and it should have excellent compatibility with
all the chemicals in treatment bath, Suitable products are relatively hydrophobic surfactants,
many of which also contain a proportion of solubilized or emulsified oil or wax.

Sequestrant:
Sequestering agents or Chelating agents remove a metal ion from a solution system by forming a
complex ion that does not have the chemical reactions of the ion that is removed. Sequestering
agents or Chelating agents are used to eliminate water hardness and heavy metals, such as iron
and copper which can affect the scouring process. These agents bind polyvalent cations such as
calcium and magnesium in water and in fibres, thus preventing the precipitation of soaps. If
polyvalent ions are present, insoluble soaps may form, settle on the fabric and produce resist
spots. There are four major types of sequestering agents to choose from: inorganic
polyphosphates, aminocarboxylic acids, organophosphonic acids, and hydroxycarboxylic acids.
The inorganic polyphosphates such as sodium tripolyphosphate and sodium hexametaphosphate
are probably the best overall in that in addition to sequestering most metals they also aid in
cleansing the fibres. They may, however, hydrolyze at high temperature and loose their
effectiveness. The aminocarboxylic acid types such as ethylenediaminetetraacetic acid (EDTA)
are very good in that they sequester most metal ions and are very stable under alkaline
conditions. They are the most used types. The organophosphonic acid types such as
ethylenediaminetetra (methylene phosphonic acid) are also very effective but comparatively
expensive. Oxalates and hydroxycarboxylic acids (citrates, etc.) are excellent for sequestering
iron but not effective for calcium and magnesium. In order to quickly and effectively bring the
chemicals to the textile material, i.e. to improve their wettability and to ensure that the fibrous
impurities will be removed as far as possible, it is necessary to add surfactants with good wetting
Page 11 of 19
and washing/emulsifying properties. A surfactant of optimal versatility to be used for
preparation, and in particular for the scouring and bleaching processes, ought to meet the
following requirements.
Uses of Sequestering Agents
The three main stages in which sequestering agents are used are
1.Pretreatment 2.Bleaching 3.Dyeing

Dispersing Agent:
Unleveled dyeing problems can be of two categories: Gross unlevelness hroughout the material
or localized unlevelness e..g. barriness, skitteriness. There are two fundamental mechanisms that
can contribute to a dyeing.
1. Control of the exhaustion dye so that it is taken up evenly.
2. Migration of dye after initially unleveled absorption on the fibre.
3. Non-ionic agent usually from water soluble complexes with the dye, some degree of
solubilization being involved.
4. Ionic agent are primarily dye-of fibre-substantive ; in the former case they tend to form
complexes with the dye and there is competition between the leveling agent and the fibre
for the dye, while in the latter case the competition is between the leveling agent and the
dye for the fibre.

Peroxide Killer:
After bleaching the cellulosic fiber with hydrogen peroxide, the fiber is subjected a thorough hot
wash cold wash and neutralization processes. These operations would remove all superficially
available chemicals that were used in bleaching process.
However in practice it is found that the core alkali i.e. the alkali due to the use of caustic soda or
soda ash and hydrogen peroxide, wetting agents and other auxiliaries would remain in the core of
the fiber processed even after 2 or 3 washes. These residual chemicals like alkali's and peroxide
are detrimental to the production of uniform flawless fabric production.
The core residual alkali would lead to immature hydrolisation of the reactive dyes and results in
streaky and uneven dyeing.
The residual peroxide present in the fiber will oxidize the reactive dyes' chromophore that
contain the metal ions and lead to tonal variation and sometimes uneven dyeing. In some cases
the chrmophore itself is getting destroyed into a colorless product and lead to pale or white
patchy dyeing. Hence the removal residual alkali and peroxide are very much essential before
starting a good dyeing operation. So any chemical that kills the residual peroxide in the fiber is
called a peroxide killer. All reducing agents are in fact peroxide killers. Again we should note
Page 13 of 19
that excess presence of reducing agent in the fiber also lead to destruction of dyestuff molecule.
Hence a careful selection of a peroxide killer is very much essential. Now in the market there are
many enzymatic peroxide killers available that will remove the residual peroxide and die-off
during subsequent dyeing operations at higher temperatures.

Enzyme:
Enzymes are present in living organism and are themselves not living organism. Structurally they
resemble protein of varying complexity based on chain of amino acid linked by peptide linkage.
Each enzymes is different from other enzyme and the dept is due to-
 Particular amino acid present
 The order in which amino acid are linked
 The presence of absence of metal ion
 The conformation of structure as a whole.
Classification of Enzyme For Textiles:
Enzymes for textiles use can be classified as follows-
1. Amylases
2. Lipases
3. Pectinase
4. Cellulas
A short description of above enzymes are given below:
Amylases: It convert amylose or amylopectin polymeric commonly referred to as starch into
water soluble shorter chain sugars. It is isolated from bacteria, fungi, pancreases and malt.
Page 14 of 19
Lipases: Cotton waxes consists of various hydrocarbons, fatty alcohol and acids, and their
respective esters. These fats and waxes are the major reason for the hydrophobic nature of
unscoured cotton fiber. Lipases hydrolyses fat and oils into alcohol & organic acid.
Pectinase: Pectinic compound as found in raw cotton mainly consist of neutral and acidic
heteropolysaccharides with different molecular weight and degrees of esterification. Pectinases
capable of hydrolyzing pectinic substances are generally enzyme complexes containing esterases
and depolymerases with random or terminal activities.
Cellulase: Cellulases enhance the effect of pectinase to a certain extent and add softness to the
cotton fabric .They often accompany pectinases in small amount. If used for scouring, cellulases
hydrolyze cotton cellulose, lifting off non cellulosic impurities in the course of reaction.
Advantages of Enzyme in Textile Wet Processing:
Because of the properties of enzymes, they make the textile manufacturing process much more
environmentally. Generally, they:
 Operate under milder conditions (temperature and pH) than conventional process
chemicals – this results in lower energy costs ( up to 120 kg CO2 savings per ton of
textile produced) (4) ;
 Save water – reduction of water usage up to 19,000 liters per ton of textiles bleached;
 Are an alternative for toxic chemicals, making waste water easier and cheaper to treat.
 Are easy to control; do not attack the fiber structure with resulting loss of weight,
resulting in better quality of material;
 Better and more uniform affinity for dyes;
 Contribute to safer working conditions through elimination of chemical treatments during
production processes;
 Are fully biodegradable.

Binders:
These are used to bind the pigment or dyes onto the fabric. It is clear from the results that the
color strength of printed cotton fabric depends on binders' type and concentration as well as the
Page 15 of 19
fixation temperature. It can be seen that for almost type of binders color strength of printed
cotton fabric is higher at low concentration and this is true irrespective of the fixation
temperature. This may be due to the probability of self polymerization at higher concentration. It
is also clear that K/S of the fabric printed using pastes including the synthesized binders are
higher than the color strength of fabric printed with pastes including the commercial binder, this
hold is true at only low temperatures. From figure 8 it is clear that, the synthesized binders give
acceptable results for color strength values at low fixation temperature. This may be attributed to
the presence of functional groups (double bond, hydroxyl groups) which are able to increase the
crosslinking density. We can conclude that binders 1, 3 and 6 have the best results for color
strength at low fixation temperature and low binder concentration.

  • 5. Page 5 of 19 As we say that disperse dyes enters in the non crystalline region of the polyester at high temperature, than acetic acid has a great role. we should have to maintain pH 4-5 for dye fixation. Since our inception, we have been satisfying our global clients offering acetic acid with molecular formula CH3COOH. Acetic acid offered by us is a clear liquid free from suspended matter having pungent odor at temperature above crystallization point. We procure textile acetic acid from reliable sources and are stringently tested at our end for purity, quality, composition and formulation. Widely used in the textile industry, these acids are colorless liquid or crystals in appearance. Acetic acid is a weak acid. It is available at different concentrations. Highly concentrated acetic acid at 98% and above is called glacial acetic acid because its freezing point range is between 13.3 ºC (98%) and 16.7 ºC (100%). Glacial acetic acid is flammable. The concentration of acetic acid can easily be determined using acid–base titration with phenolphthalein as an indicator. The water used should be free from CO2, prepared by boiling before use Oxalic Acid: Oxalic Acid also use in textile industry to maintain pH. To develop the color or printed fabric & to fix the dye on the fabric permanently. Oxalic acid offered by us is the compound with the chemical formula H2C2O4. This is a dicarboxylic acid and can be well again described with the formula HOOCCOOH. It acts as a relatively strong organic acid as it is about 3,000 times strong as acetic acid. These are used as a mordant in dyeing processes in the Textile industry. Soda Ash: Na2CO3 also use in textile industry to maintain pH. To develop the color or printed fabric & to fix the dye on the fabric permanently. Sodium carbonate (Na2CO3) is also called soda ash. In textile wet processes, it is often available in anhydrous form. Its purity can be > 99% Na2CO3 (58% Na2O). If the concentration of a Na2CO3 solution needs to be determined, a titrimetric method identical to the ones listed for NaOH in this section can be used. Na2CO3 is a medium type of alkali compare to NaoH. It use to maintain pH from 8-11. Sodium Hipochloride: Sodium Hypochlorite is a greenish-yellow liquid commonly referred to as "Bleach." The chemical formula for Sodium Hypochlorite is NaOCl. Sodium Hypochlorite is prepared by reacting dilute caustic soda solution with liquid or gaseous chlorine, accompanied by cooling. In hypochlorite bleaching of textiles, active chlorine is the species measured for the control of the bleaching process. Iodometry is the method used to determine the content of active chlorine. Sodium Hipochloride is the strongest oxidation agent because it capable to giving oxygen at room temperature. By using sodium hipochloride bleaching in industry now a days is absolute because of extra process is required for remove chlorine which is costly. The process of removing of chlorine called anti chlor treatment. This is the main dis advantage of Sodium Hipochloride bleaching.
  • 6. Page 6 of 19 Sulphuric Acid: Sulphuric Acid use in textile industry to maintain pH. To develop the color or printed fabric & to fix the dye on the fabric permanently. It is on of the strongest acid. By use it we can increased pH rapidly. But it also have some disadvantage. It dissolved cellulose of cotton & depredate fiber. Hydrochloric Acid: Hydrochloride acid used in Textile bleaching, Bleaching of cotton fabrics, Wool scouring (see article),Bleaching of wool, Waste water treatment (see article), Measuring dissolved oxygen & neutralization of alkali. Bleaching Agent:  Hydrogen peroxide: Hydrogen peroxide is the simplest peroxide and an oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution it appears colorless. Hydrogen peroxide Brand name, their manufacturer & structure Chemicals name Manufacturer Brand name Origin Structure Hydrogen peroxide ZhanJiang Chikan Huanan Chemical Industry Dioxidane China Daifu Industries Group Co., Limited Daifu China Karry Industry Co., Ltd KR China Function, Uses, Advantage & Dis advantage of Bleaching Agent:- Hydrogen peroxide: Hydrogen peroxide is seen as an environmentally safe alternative to chlorine-based bleaches. H2O2 can be use for bleaching cotton silk jute. Less water is required for peroxide bleaching. For bleaching of colored cotton goods peroxide is better than hypochloride. There is generally no need for through scouring before peroxide bleaching. Peroxide ha excellent storage stability. It is involves low risk of chemical damage of cotton. The main disadvantage of peroxide bleaching is peroxide lefy on fabric causes uneven dyeing. Salt or Electrolytes:  Glubar salt (Sodium sulfate)  Common Salt (NaCl)  Caustic Soda (NaOH)
  • 7. Page 7 of 19 Salt use in textile industry as a Electrolytes to increase the affinity of dyestuff towards fibre. Salt Brand name, their manufacturer & structure Chemicals name Manufacturer Brand name Origin Structure Glubar salt (Sodium sulfate) Shanxi Xihui Technology Co., Ltd. XiHui China Common Salt (NaCl) Heze Datong Chemical Co., Ltd DT-HZ China Caustic Soda(NaOH) Losange Chemicals Sdn Bhd LC-99 Malaysia Function, Uses, Advantage & Dis advantage of Salt:- The textile substrate and dye molecule, not necessarily should have of homogeneous characteristics to combine with each other. In such case, we require some catalyst to facilitate dyeing action on fabric. Salt plays this crucial role of catalyst. Salt has an extremely high affinity for water. Broadly speaking, Salt is necessary in three ways, firstly, to drive dye into textile during the dyeing process in textile. Secondly, use of salt leads to maximum exhaustion of dye molecules during dyeing process in textiles. Thirdly it is used as an electrolyte for migration, adsorption and fixation of the dyestuff to the cellulose material. Salts plays important role in reactive dyeing by improving the affinity of the dyestuff towards the fibre and acceleration of the dyestuff's association and lowering its solubility. Normally, Glauber's salt or common salt/ vacuum salt is used for this purpose. The presence of chlorine ion in the common salt may cause corrosion of the equipment. Hence, Glauber's salt is always preferred over common salt. Glauber's salt is a common name for sodium sulfate decahydrate, Na2SO4.10H2O; it occurs as white or colorless monoclinic crystals. Upon exposure to fairly dry air it effloresces, forming powdery anhydrous sodium sulfate. Johann Glauber’s was the first to produce the salt (from Hungarian spring waters). Glauber's salt is water soluble, has a salty, bitter taste, and is sometimes used in medicine as a mild laxative; it is also widely used in dyeing. Vacuum salt is the common name of sodium chloride (NaCl). The salt in the reactive dyeing increases the affinity of the dye towards the Cellulosic substrate. Salt increases the exhaustion rate of reactive dyestuffs. As reactive dyestuffs have a lower affinity, more inorganic salt is required when using reactive dyestuffs in order to accelerate absorption.
  • 8. Page 8 of 19 While the amount of inorganic salt used varies according to the type of dyestuff used, recently developed high-fixation dyestuffs with improved affinity allow the amount of inorganic salt to be reduced. Due to considerations of effectiveness and cost, both Glauber's salt and common salt (sodium chloride) are used in dyeing. In terms of their role as an inorganic salt, these two are effectively the same because of the sodium cation active in both. Scouring Agent This is needed to remove the oil , fats etc from the fabric. The term ‘scouring’ applies to the removal of impurities such as oils, was, gums, soluble impurities and sold dirt commonly found in textile material and produce a hydrophilic and clean cloth. To remove natural as well as added impurities of essentially hydrophobic character as completely as possible. To increase absorbency of textile material To leave the fabric in a highly hydrophilic condition without undergoing chemical or physical damage significantly. Chemicals name Manufacturer Brand name Origin Scouring Agent Zhejiang Transfar Co.,Ltd TF-120C China Karry Industry Co., Ltd KR China Zhejiang Transfar Co., Ltd Transfar China Wuxi Yicheng chemical CO.LTD YICHENG China In the scouring process the cotton cellulose material is treated with a solution containing alkali ( soda ash and caustic soda), an anionic and/or nonionic detergent, a wetting agent, a complexing and sequestering for the removal of metal ions and polyacrylates or polyphosphonates as special surfactant free dispersing agents, at high temperature.The scouring operation was conventionally
  • 9. Page 9 of 19 done in kiermachines and hence the process was called kier boiling, but now a days the scouring is done mostly in the dyeing machines itself as a part of combined or single operation such as scouring and bleaching. Saponification of fats into water soluble soap and water miscible glycerin under alkaline conditions. Hydrolysis of proteins into water soluble degradation products. Dissolution of amino compounds. Solubilising of pectose and pectins by converting into soluble salts. Dissolution and extraction of mineral matter. Emulsification and solubilisation of natural oils and waxes. Removal and dispersion of dirt particles and kitty by the action of alkali and detergent. The material after scouring is more absorbent , free from natural impurities and coloring matter.This treatment can be carried out on filaments, yarns and fabrics. Anti foaming agent: Used to prevent formation of foam during stirring or during dyeing in one bath. Where the present and persistence of foam is a nuisance, defoaming agents or antifoams are used. For maximum efficiency deform should be added to baths when necessary.

Page 10 of 19 is it should from a thin uniform protective coating around the fiber to lower the surface friction and flexural rigidity, thus minimizing the formation of durable creases during high temperature processing. The most suitable lubricant should have the properties so that it helps to emulsify, it does not undergo phase separation with extreme changes in pH and temperature, e.g. it is stable in high temperature and over a wide range of pH; and it should have excellent compatibility with all the chemicals in treatment bath, Suitable products are relatively hydrophobic surfactants, many of which also contain a proportion of solubilized or emulsified oil or wax.

Transfar China Chengdu Silike Technology Co., ltd SILIKE China Sequestrant: Sequestering agents or Chelating agents remove a metal ion from a solution system by forming a complex ion that does not have the chemical reactions of the ion that is removed. Sequestering agents or Chelating agents are used to eliminate water hardness and heavy metals, such as iron and copper which can affect the scouring process. These agents bind polyvalent cations such as calcium and magnesium in water and in fibres, thus preventing the precipitation of soaps. If polyvalent ions are present, insoluble soaps may form, settle on the fabric and produce resist spots. There are four major types of sequestering agents to choose from: inorganic polyphosphates, aminocarboxylic acids, organophosphonic acids, and hydroxycarboxylic acids. The inorganic polyphosphates such as sodium tripolyphosphate and sodium hexametaphosphate are probably the best overall in that in addition to sequestering most metals they also aid in cleansing the fibres. They may, however, hydrolyze at high temperature and loose their effectiveness. The aminocarboxylic acid types such as ethylenediaminetetraacetic acid (EDTA) are very good in that they sequester most metal ions and are very stable under alkaline conditions. They are the most used types. The organophosphonic acid types such as ethylenediaminetetra (methylene phosphonic acid) are also very effective but comparatively expensive. Oxalates and hydroxycarboxylic acids (citrates, etc.) are excellent for sequestering iron but not effective for calcium and magnesium. In order to quickly and effectively bring the chemicals to the textile material, i.e. to improve their wettability and to ensure that the fibrous impurities will be removed as far as possible, it is necessary to add surfactants with good wetting

A surfactant of optimal versatility to be used for preparation, and in particular for the scouring and bleaching processes, ought to meet the following requirements. Uses of Sequestering Agents The three main stages in which sequestering agents are used are 1.Pretreatment 2.Bleaching 3.Dyeing Chemicals name Manufacturer Brand name Origin Sequestrant GLORY SAIL INTERNATIONAL LOGISTICS LTD. Glorysail Logistics China StarFly Logistics Co., Ltd CLR China Dispersing Agent: Unleveled dyeing problems can be of two categories: Gross unlevelness hroughout the material or localized unlevelness e..g. barriness, skitteriness. There are two fundamental mechanisms that can contribute to a dyeing. 1. Control of the exhaustion dye so that it is taken up evenly. 2. Migration of dye after initially unleveled absorption on the fibre. 3. Non-ionic agent usually from water soluble complexes with the dye, some degree of solubilization being involved. 4. Ionic agent are primarily dye-of fibre-substantive ; in the former case they tend to form complexes with the dye and there is competition between the leveling agent and the fibre for the dye, while in the latter case the competition is between the leveling agent and the dye for the fibre.

Page 12 of 19 Dye Fixing Agent: Properties of a good fixing agent includes good capability with cross linking agents without promoting yellowing effect; good leveling and migration properties, does not affect the shade, has good affinity for the fiber, stable to steaming and dry heat, and improved all round fastness properties of the fabric or yarn. Fixative is generally used after completing the dyeing or in printing paste.

Snoor Chemicals China Peroxide Killer: After bleaching the cellulosic fiber with hydrogen peroxide, the fiber is subjected a thorough hot wash cold wash and neutralization processes. These operations would remove all superficially available chemicals that were used in bleaching process. However in practice it is found that the core alkali i.e. the alkali due to the use of caustic soda or soda ash and hydrogen peroxide, wetting agents and other auxiliaries would remain in the core of the fiber processed even after 2 or 3 washes. These residual chemicals like alkali's and peroxide are detrimental to the production of uniform flawless fabric production. The core residual alkali would lead to immature hydrolisation of the reactive dyes and results in streaky and uneven dyeing. The residual peroxide present in the fiber will oxidize the reactive dyes' chromophore that contain the metal ions and lead to tonal variation and sometimes uneven dyeing. In some cases the chrmophore itself is getting destroyed into a colorless product and lead to pale or white patchy dyeing. Hence the removal residual alkali and peroxide are very much essential before starting a good dyeing operation. So any chemical that kills the residual peroxide in the fiber is called a peroxide killer. All reducing agents are in fact peroxide killers. Again we should note
  • 13. Page 13 of 19 that excess presence of reducing agent in the fiber also lead to destruction of dyestuff molecule. Hence a careful selection of a peroxide killer is very much essential. Now in the market there are many enzymatic peroxide killers available that will remove the residual peroxide and die-off during subsequent dyeing operations at higher temperatures.

Haichuang China Enzyme: Enzymes are present in living organism and are themselves not living organism. Structurally they resemble protein of varying complexity based on chain of amino acid linked by peptide linkage. Each enzymes is different from other enzyme and the dept is due to-  Particular amino acid present  The order in which amino acid are linked  The presence of absence of metal ion  The conformation of structure as a whole. Classification of Enzyme For Textiles: Enzymes for textiles use can be classified as follows- 1. Amylases 2. Lipases 3. Pectinase 4. Cellulas A short description of above enzymes are given below: Amylases: It convert amylose or amylopectin polymeric commonly referred to as starch into water soluble shorter chain sugars. It is isolated from bacteria, fungi, pancreases and malt.
  • 14. Page 14 of 19 Lipases: Cotton waxes consists of various hydrocarbons, fatty alcohol and acids, and their respective esters. These fats and waxes are the major reason for the hydrophobic nature of unscoured cotton fiber. Lipases hydrolyses fat and oils into alcohol & organic acid. Pectinase: Pectinic compound as found in raw cotton mainly consist of neutral and acidic heteropolysaccharides with different molecular weight and degrees of esterification. Pectinases capable of hydrolyzing pectinic substances are generally enzyme complexes containing esterases and depolymerases with random or terminal activities. Cellulase: Cellulases enhance the effect of pectinase to a certain extent and add softness to the cotton fabric .They often accompany pectinases in small amount. If used for scouring, cellulases hydrolyze cotton cellulose, lifting off non cellulosic impurities in the course of reaction. Advantages of Enzyme in Textile Wet Processing: Because of the properties of enzymes, they make the textile manufacturing process much more environmentally. Generally, they:  Operate under milder conditions (temperature and pH) than conventional process chemicals – this results in lower energy costs ( up to 120 kg CO2 savings per ton of textile produced) (4) ;  Save water – reduction of water usage up to 19,000 liters per ton of textiles bleached;  Are an alternative for toxic chemicals, making waste water easier and cheaper to treat.  Are easy to control; do not attack the fiber structure with resulting loss of weight, resulting in better quality of material;  Better and more uniform affinity for dyes;  Contribute to safer working conditions through elimination of chemical treatments during production processes;  Are fully biodegradable.

It is clear from the results that the color strength of printed cotton fabric depends on binders' type and concentration as well as the
  • 15. Page 15 of 19 fixation temperature. It can be seen that for almost type of binders color strength of printed cotton fabric is higher at low concentration and this is true irrespective of the fixation temperature. This may be due to the probability of self polymerization at higher concentration. It is also clear that K/S of the fabric printed using pastes including the synthesized binders are higher than the color strength of fabric printed with pastes including the commercial binder, this hold is true at only low temperatures. From figure 8 it is clear that, the synthesized binders give acceptable results for color strength values at low fixation temperature. This may be attributed to the presence of functional groups (double bond, hydroxyl groups) which are able to increase the crosslinking density. We can conclude that binders 1, 3 and 6 have the best results for color strength at low fixation temperature and low binder concentration.
