Various Chemicals Used in Textile Industry



Various Chemicals used in Textile Industry


Pre-treatment Chemicals

De-sizing Agent

This is used to remove the different types of sizes (Starch, waxes etc.) from the fabric/yarn

Wetting and Penetrating Agent

This is needed to reduce the surface tension of water and thus increase the absorbency of the water to the fabric

Sequestering Agent & Protective Colloid

This is needed to reduce the hardness of water and thus make ideal conditions for washing

Scouring Agent

This is needed to remove the oil , fats etc from the fabric.

Silicone & Non Silicone Defoamers

These are needed to reduce the foam created during the process of treatment of fabric

Non-Silicate Peroxide stabilizer

This is used to stabilize the peroxide of hydrogen peroxide in the pretreatment process.

Peroxide Killer

This is used to clear the residual peroxide from the fabric

Polyester Weight Reducing Catalyst

This is used to reduce the weight of the polyester fabric during the caustic addition process

Anti-back Staining Agent

This is used to prevent the staining of the pockets during the denim fabric treatment

Dyeing Chemicals

Sequestering Agent

It is used to reduce the hardness of water and thus make ideal condition for processing

Silicone & Non Silicone Defoamers

These are used to reduce the foam created during the process

Buffering Agent

These are used to maintain the pH of dye bath throughout the dyeing process

Polyester Dyeing Carriers

These are used to facilitate easy absorption and penetration of dyes by the polyester fabric

Dispersing Agent & Oligomer Removing Agent

This is used to maintain the dispersion of dyes in the dyeing process and help to remove oligomers

Levelling Agent

This is used to get even dyeing and even colour depth effect

Lubricants

To reduce the friction between fabric to fabric and fabric to machine and to reduce the creation of creases in the fabric

Washing off Agent

To remove the unfixed dyes from the fabric

Dye-fixing Agent

To fix the dyes on to the fabric

Soda Ash Substitute

To substitute soda ash in the dyeing process of cotton.

Cationising Agent for Pigment Dyeing

To provide required cationic charge to the fabric in the pigment dyeing process

Printing Chemicals:

Dispersing, Penetrating, Swelling, Levelling & Defoaming Agent

This is used to provide depth and even level printing effect, being added in the printing paste

Fixation Accelerators

These are used to provide depth and fixation of dyes to the polyester printing fabric in loopager machine during the disperse printing process

Binders Acrylic, Self Thickening for Gold & Flock

These are used to bind the pigment or dyes onto the fabric

Fixers in Pigment Printing

These are used to provide fastness to the print

Thickeners

These are used to provide viscosity to the printing paste to facilitate required printing effect

White Inks

These are used to provide printing effect onto the fabric

Washing Off Agent

This is needed to remove the unfixed dye from the printed fabric

Finishing Chemicals:

Stiffeners

This is used to provide stiff finish effect to the fabric

Softeners

These are used to provide soft finish effect to the fabric

Silicone Emulsion

This is used to provide silky and soft finish effect to the fabric

Wax Finishing Agent

This is used to provide waxy finish to the fabric

Anti Static Agent

This is used to reduce the static power of the fabric

Water Repellant & Soil Resisting Agent

This is used to provide water repellency and dust repellency to the fabric

Polyurethane Finishing Agent

This is used to provide bouncy feel to the fabric

Crease Recovery Agent

This is used to reduce the crease and provide wrinkle free effect to the fabric

Delustering Agent

This is used to remove the luster from the viscose fabric

Anti-pilling & Anti-Slip Agents

These are used to remove the hairing and pilling problems from the fabric and also provide anti-slip effect

Enzymatic Bio-polishing Agent

This is used to remove the surface protruding fibers from the knit substrates and denim and thus improvise the surface feel
