What is bio-polishing pf cotton?

Biopolishing is a process used to improve the surface properties of cotton fabric. It involves the use of enzymes to remove or modify the surface fibers of cotton, resulting in a smoother, more uniform surface with a softer feel.
In the biopolishing process, the cotton fabric is treated with enzymes such as cellulase, which breaks down the surface fibers and removes any protruding fibers or fuzz. This results in a smoother surface, which gives the fabric a softer, silkier feel.
The biopolishing process has several benefits, including improving the fabric’s dye uptake, reducing pilling, and increasing its resistance to shrinkage. It also results in less lint and fuzz, which makes the fabric more attractive and easier to care for.
Biopolishing is an environmentally friendly process since it uses natural enzymes instead of harsh chemicals. It is commonly used in the textile industry for producing high-quality cotton garments, such as shirts, blouses, and other apparel items.
