Enzymes for the Textile Industry

Enzymes provide help during many parts of the textile processing and ensure the creation of high quality products while support manufacturers in cutting down their consumption of water, chemicals and energy and all these in a substantially shortened processing time. Enzymes are highly effective and can work under gentle conditions, while accepting combined processes.

 

The role of enzymes during specific parts of textile processing:

1. Scouring. The process of removing waxes and other impurities from the fabric is essential before it can be used for commercial purposes.

Conventional practice: High temperatures and high consumption of chemicals such as sodium hydroxide, sodium carbonate and hydrogen peroxide are required.

Enzymes: Bioscouring is the process when enzymes are used for scouring, saving like this water, chemicals and energy. With bioscouring the enzyme removes all pectin compounds in the raw cotton.

2. Bleach clean-up. Bleaching is necessary for the removal of natural colouring matter from the fabric which appears whiter after this.

Conventional practice: A reducing agent or hot water for rinsing have to be used, but both methods require big water consumption.

Enzymes: Bleaching with enzymes require lower temperatures and fewer rinses, which saves energy on heating and water.

3. Desizing. After a fabric has been woven, the warp size must be removed before the fabric is sent on to the finishing step.

Conventional practice: Depending on the size that has to be removed, the cloth may be treated with chemicals such as acids, bases or oxidizing agents, or washed with hot water.

Enzymes: Enzymatic desizing on the other hand diminishes the requirement for chemicals, while retaining fabric strength with enzymes gentle action.

4. Bio-polishing: This is the process that prevents fabric from forming pills and ensures that textiles get longer durability and robustness.

Conventional practice: Bio-polishing constitutes a separate step in the textile processing, usually after the bleaching agents are rinsed out from the fabric and before fabric dyeing. 

Enzymes: With our enzymatic solutions you can concentrate the three-step "bleach clean-up-bio-polishing-dyeing" or the two-step "bio-polishing-dyeing" to a single process, saving thus the consumption of time, water, energy, and chemicals.

5. Abrasion: The stone-washed look in jeans has always been very popular to consumers, abrasion is a very common process during denim fabrics manufacturing.

Conventional practice: Traditionally pumice stones are being used for the abrasion process, but fabric makers encounter various problems, as stones are hard on processing equipment, they generate large amounts of sludge, etc, not to mention the hard work of adding and removing the stones. Moreover, this conventional process requires prewash, so that the denim fabric gets prepared for abrasion.

Enzymes: As an alternative to pumice stones, enzymes are able to loosen the indigo colour and therefore create a high-quality abrasion. With enzymes you may avoid the use of pumice stones or other auxiliaries. Moreover, the enzymatic solution that AlincaVelco supplies you for abrasion includes prewash.
