Enzymes are an eco- friendly alternative to chemicals in textile and fiber processing techniques. Being protein catalysts that are produced by living cells, they speed up specific chemical and biochemical reactions. As compared to the conventional chemicals textile enzymes are less hazardous to the environment.
Nature Bio Science textile enzymes have high specificity as regards catalytic action. These are the high molecular weight protein that significantly escalate reaction rate and plummet costs. Being less hazardous for textile workers Enzymes for textile process not only need less water but also give satisfactory results with low energy consumption.
Enzymes for textile industry cater better results and operate under milder conditions. They work under optimum temperature; optimum pH levels and is highly specific in action. This makes them easy to control. Textile Enzymes are biodegradable and anti-toxic and are a better choice over the carcinogenic chemicals. These seldom damage the original fabric hence foster better quality of the fabric.
Enzymes for textile process generally constitute Amylases, Pectinases,Lipases, Cellulases and Peroxidases which work towards catalyzing the preparatory process of a textile. The applicability of these enzymes for textile industry helps in various processes given underneath:
An amylase enzyme is used for desizing processes at low-temperature (30-60ºC) and optimum pH is 5,5-6,5. These enzymes are specific for starch, removing it without damaging the support fabric.
Scouring is removal of non-cellulosic material present on the surface of the cotton. Enzymatic scouring makes it possible to effectively scour fabric without negatively affecting both the fabric and the environment.
The purpose of cotton bleaching is to decolorize natural pigments and to confer a pure white appearance to the fibers. The most common industrial bleaching agent is hydrogen peroxide which decreases the degree of polymerization and, fosters severe damage. The replacement of hydrogen peroxide with an enzyme would lead to better fabric quality.
The main objectives of the bio-polishing is to upgrade the quality of the fabric by implementing modifications on the surface structure of the fiber, hence making it soft and smooth. The smoothening and polishing through conventional chemical methods is temporary as the chemicals are removed after few washes leading to fuzz formation. Bio-polishing is permanent and it keeps the fabric in good condition even after repeated washes making the products more enticing to the customer.
Enzymatic Treatment of Denim
Being a heavy grade cotton, Denim requires to be deeply treated for attaining perfection. Treating the fabric with enzymes is a perfect option because they are absorbed deeply thereby decreasing chances of future fading.
