The process of biopolishing typically involves the following steps:

Preparation of fabric: The cotton fabric is prepared by washing and bleaching, if necessary, to remove any impurities or stains.

Enzyme treatment: The fabric is then treated with a solution containing cellulase enzymes. The enzymes break down the protruding fibers and fibrils on the surface of the cotton fabric, resulting in a smoother and more uniform surface.

Washing: The fabric is washed thoroughly to remove the broken-down fibers and fibrils, as well as any residual enzyme solution.

Drying: The fabric is dried, either by air-drying or using a machine dryer.

Finishing: The fabric can be finished using various techniques, such as softening, shearing, or brushing, to further enhance its properties and appearance.

The specific conditions and parameters of the biopolishing process, such as the enzyme concentration, treatment time, temperature, and pH, can vary depending on the type of cotton fabric and the desired results. The process is typically carried out using industrial-scale machinery, such as continuous washing machines or batch-wise kiers, in order to achieve consistent and efficient results.
Biopolishing is a process used in the textile industry to enhance the surface properties of cotton fabrics. It involves the use of enzymes to remove the protruding fibers and fibrils from the surface of the cotton fabric, resulting in a smoother and more uniform surface.
The enzymes used in biopolishing are typically cellulases, which break down the cellulose fibers on the surface of the cotton fabric. During the biopolishing process, the fabric is treated with the enzyme solution and then washed to remove the broken-down fibers and fibrils.
