Chemicals used in the textile industry

Chemicals Used in the Textile Sector and Their Application Areas

Chemicals used in the textile sector play a role in many stages such as fiber processing, dyeing, finishing, and protection. These chemicals both enhance product quality and impart special functional properties to fabrics (water repellency, wrinkle resistance, antibacterial effect, etc.).

1.Cleaning and Preparation Chemicals

They ensure the raw fabric becomes workable.

• Wetting agents and detergents:Reduce surface tension, remove impurities

• Bleaches (Hydrogen Peroxide,Sodium Hypochlorite):Whitens the fabric

• Enzymes (cellulase, amylase):Natural polishing, dehairing

• Oil and stain removers:Remove oils from the fiber surface

2.Dyestuffs (Dyes)

Impart color to fabrics.

• Reactive dyes:For cotton fabrics, wash-resistant

• Disperse dyes:For synthetic fibers (polyester, etc.)

• Acid dyes:For protein-based fibers like wool and silk

• Pigment dyes:Generally used in printing

3.Auxiliary Chemicals

Support dyeing and printing processes.

• Dispersants:Ensure even distribution of dye on fibers

• Salt and soda:Fixation in reactive dyeing

• Agents (sequestering, leveling):Maintain dyeing balance

• pH regulators:For healthy progression of reactions

4.Finishing Agents

Give the final form to the fabric, impart performance properties.

• Softening agents:Make the fabric more comfortable

• Wrinkle-free finishes (formaldehyde resins):Easy-iron fabrics

• Water and oil repellent chemicals (fluorocarbon, silicone-based):Used in outerwear

• Antibacterial agents:In healthcare textiles (hospitals, sportswear)

• Flame retardants:For occupational safety textiles

5.Coating and Impregnation Chemicals

Used to give special functions to the fabric.

• Polyurethane and acrylic resins:Waterproofness, durability

• Latex:Flexibility and surface protection

• Nanocoatings:Advanced functionality (anti-stain, easy-cleanability)
