Normally, some of the important textile chemicals used in the textile industry in the following.
1. Soda:
Color fixing by forming covalent bonds & also PH control is used to increase fabric absorbency.
2. Per-oxide:
Used to remove the natural gray color in the fabric.
3. Stabilizer:
Used to stabilize the reaction of peroxidase. The peroxide will quickly deplete the peroxyl ions responsible for bleaching if not used.
4. Detergent:
Used as a wetting or cleaning agent.
5. Antiaging Agents:
Fabric folds or creases during knitting & wet processing may result in uneven shade during dyeing. So to remove it, a crease remover is used so that the crease does not wear. It is a lubrication-type chemical.
6. Sequestering Agent:
Metal ions in water are used to remove hardness & soften water.
7. Waiting Agent:
Used to increase the wetting ability of fabric by removing surface tension. It improves the waiting property.
8. Reduction Agent:
Used to remove extra dyes adhering to the fabric surface.
9. Soaping agent:
Used while washing the fabric to remove excess color. It is liquid soap.
10. Enzymes:
Used to soften the fabric to remove hairiness. The enzyme removes peeling.
11. Antifoaming agent:
Used to prevent foam from forming in the dye bath. This chemical is used to prevent the liquor from foaming.
12. Softener:
It is generally used to increase the surface luster of the fabric and to make the fabric soft. It increases the hand feel and suaveability of the fabric.
13. Hydrogen:
Stripping is used to remove the color from the fabric. It is called a reducing agent.
14. Leveling Agent:
Dyes are used for the uniform distribution of chemicals in the fabric. It is called a dye retendering agent.
15. Salt:
Electrolight helps to bring the dyes from the dye bath to the surface of the fabric. By neutralizing the charge.
16. Fixing Agent:
Used for color fixing.
17. O.B.A.:
Optical brighteners are used to increase the brightness, whiteness of fabric.
18. Hydrogen Remover:
Used to weaken & remove the action of Hydros.
19. Acetic acid:
Used to neutralize fabric, remove basic conditions & control PH. It is the most widely used acid in textiles
20. Dispersing agent:
Polyester fabric is used for uniform penetration of dyes. It is also called the leveling of polyester.
21. Sodium Acetate:
Used to stabilize or control pH during polyester dyeing. It is also called the buffering agent.
22. Oil Remover:
Used to remove oil marks on fabric.
23. Lubricants:
Lubricants are used to remove static electricity within textile materials
24. Apriton:
It is a chemical like calcium oxide, which hardens the fabric.
25. PVA Gum:
Polyvinyl alcohol is a polymer that hardens the fabric.
26. Alginate Gum:
It is a natural gum, which helps to increase the viscosity of the liquor solution.
