KIER TREATMENT AND ENZYME DYEING

A kier or keeve is a large circular boiler or vat used in bleaching or scouring cotton fabric. When in use, they are continuously rotated by an engine, steam being supplied through a rotating joint in the axle. They are usually spherical, sometimes cylindrical.

Purposes of Kier Boiling:
Kier boiling is done for the below purposes,

• Removes natural impurities (waxes, fats, oils, pectins) from cotton fabrics.
• Improves fabric whiteness and absorbency.
• Prepares fabric for uniform dyeing, printing and bleaching.
• Enhances fabric softness and reduces yarn imperfections.
• Minimizes microbial growth, increasing durability.
• Contributes to producing high-quality, aesthetically pleasing textiles.

What is Enzyme dyeing?

Enzyme dyeing is a textile dyeing process that uses enzymes to create colorants that stick to fibers.

Benefits of Enzyme dyeing?

• Environmental impact: Enzymes are biodegradable and can reduce the amount of water and energy needed in the dyeing process. They can also reduce the toxicity of waste discharge. 
• Fabric properties: Enzymes can improve the texture and fastness properties of fabrics. 
• Dye uptake: Enzymes can help fabrics absorb dye more effectively.
• Safety: Enzymes are safe to use and the reactions are controllable.
