Application of Bioenzymes in Textile Industry

Enzymes in the textile industry include laccase, glucose oxidase, hemicellulase, ligninase, and some new enzymes. The following are the introductions of the specific applications:
1. The application of laccase in textile processing: laccase is an oxidoreductase. Denali II S of the toxic company is a genetically modified Aspergillus niger laccase, which can be used in the antique finishing of jeans. The obtained fabric has a thick handle, smooth surface, credentials, bright and elegant color.

2. Application of glucose oxygenase in textile processing: glucose oxygenase mainly carries out bleaching finishing of fabrics. This enzyme treatment is very effective in producing hydrogen peroxide. The treatment makes the fabrics feel soft and full without adding hydrogen peroxide stabilizer.

3. Application of hemicellulase and ligninase in textile processing: natural cellulose fibers contain hemicellulose and lignin, especially hemp fibers, which do not remove hemicellulose and lignin, and greatly affect the spinnability of fibers. Most of them can be cleared by hemicellulase and ligninase treatment. In addition to hemicellulose and lignin, hemicellulase and ligninase have not been used alone in textile technology, mainly using in combination with other enzymes (such as gelatinase, cellulase, etc.) for fiber treatment.

Application of new enzymes in textile processing: the position of chemical synthetic fibers and sizes in textiles is obvious. These polymers can not be biodegraded and degraded, resulting in environmental pollution. Researchers are currently studying new enzymes and screening bacteria with certain functions. Genetically modified enzymes can be used as high-performance enzymes or new enzymes that can be produced by cloning, a transgene or genetic engineering bacteria, or new enzymes that can be synthesized according to chemical biological structure and enzymatic principles. These new enzymes have become mimetic enzymes. At present, the more successful enzymes include PVA catabolism, polyester catabolism, genetic engineering bacteria for decomposing polyamide oligomers, synthetase and so on.
