Enzymes are biocatalysts that are increasingly being used in textile processing as a sustainable and non-toxic alternative to harsh chemicals. Enzymes like amylases, catalase, and laccase are used for various applications such as removing starch, degrading hydrogen peroxide, textile bleaching, and lignin-degrading. Cellulases are used for denim finishing while lactases are used for decolorization of textile effluents and bleaching. The use of enzymes in textile processing is efficient and offers specificity towards particular substrates or compounds, leading to higher-quality finished products. Moreover, enzymes can be used under milder conditions, reducing water, energy, and time wastage.
The textile industry utilizes enzymes in two stages of textile processing. During the preparatory finishing phase, amylases are used for de-sizing, and in the finishing phase, cellulases are used for softening textiles, decreasing the piling of cotton textiles, and bio-stoning. Proteases, pectinases, lipases, xylanases, and catalases are used for denim fading, bio-polishing, scouring, and removing peroxides.
Using enzymes in textile processing provides several benefits, including quickening the chemical reaction rate, enabling enzyme recycling, and offering an eco-friendly alternative to toxic chemicals. Enzymes can be used at room temperature and milder conditions, and their specificity towards particular substrates reduces the risk of interference. Moreover, enzymes are biodegradable, non-polluting, and safe to use.
Amylases, cellulases, laccases, and peroxidases are among the important enzymes used in textile processing. Amylases are used for de-sizing cotton textiles, and cellulases are used for finishing denim products. Bio-finishing and polishing of textiles, enzymatic bio-scouring, and enzymatic bleaching of textiles are other applications of enzymes in the textile industry. The use of enzymes in textile processing reduces pollution and water wastage and leads to increased profits.
In conclusion, enzymes have revolutionized the textile industry by providing a sustainable and non-toxic alternative to harsh chemicals. The use of enzymes reduces water and energy wastage, leads to higher-quality finished products, and provides a safer working environment for workers. The textile industry has embraced the use of enzymes, and their continued use will lead to a cleaner and more efficient textile processing industry.
