Table 3: Application of Enzymes in Textile Processes Sr. Fabric Conventional Process No. Type Chemicals Substituting Enzyme 01. Cellulosic Desizing Acid Alpha- amylase & lipase 02. Cellulosic Scouring Caustic and Soap Pectinase, Cellulase & Lipase Sodium chlorate, 03. Cellulosic Bleaching bleaching powder, Oxidoreductose & catalase etc. 04. Cellulosic Finishing Singeing, etc. Cellulase & protease 05. Denim Enzyme wash Stone wash Cellulase & protease 06. Carbonization Wool and Acid and alkali or and Silk soap Degumming Cellulase, pectinase & protease 07. Flax and Jute Retting Water , dew or steam Hemicellulase & pectinase 8. Enzyme Application in Different Textile Processes Distinctive enzymes are having diverse uses in textile handling. Table 3 displays the use of Enzymes in textile procedures. 9. Advantages of Enzyme used in textiles 9.1 Enzyme accelerates the reaction Figure 1: Lock and key analogy of enzyme 7. Factors Affecting on Enzymes 1. PH value: Enzymes have ideal pH 4 to 9. Past these cutoff points denaturation of enzyme happens. 2. Temperature: If the temperature is increased by 100C, the rate of the vast majority of the synthetic responses pairs. 3. Time: Time for the response is reverse to the concentration of the enzyme, i.e. progressively the concentration of the enzyme less will be the time required for response and bad habit – versa. 4. Activator: To initiate reactant action of enzyme nearness of certain bivalent metallic cations. These metals settle the structure of enzyme-substrate complex or the substrate to assault of the enzyme. 5. Inhibitor: It squares catalyzes movement of enzyme and capacity as an inhibitor. The restraint might be aggressive or nonfocused to keep an ordinary response. 1. An enzyme quickens the rate of specific response by bringing down the enactment vitality of response 2. The enzyme remains set up toward the complete of response by going about as impetus 3. The activity of the concoction at that pH and temperature is the zenith 9.2 Enzymes operate under milder condition 1. Each enzyme has ideal temperature and ideal pH i.e. action of enzyme at specific temperature and pH and is on the pinnacle 2. For the greater part of the enzyme movement corrupts on the both sides of ideal condition 9.3 Alternative for polluting chemicals 1. Enzymes can be used as best differentiating alternative to toxic, risky, pollution making chemicals 2. Also some contamination chemicals are even cancer-causing. When we utilize enzymes there is no contamination 38 Volume: 01 Issue: 01 | March-May -2017, www.ijtcs.com
Indian Journal of Textile and Clothing Science 9.4 Enzyme acts only on specific substrate 1. Most enzymes have high level of specificity and will catalyze the response with one or few substrates 2. One particular enzyme will simply catalyze a specific kind of response. Enzymes used as a piece of desizing don't impact cellulose thus there is no loss of strength of cotton 9.5 Enzyme are easy to control Enzymes are definitely not hard to control in light of the way that their development depends on perfect condition. 9.6 Enzymes are biodegradable Toward the finish of response in which enzymes utilized, we can basically deplete the rest of the arrangement since enzymes are biodegradable and don't create lethal waste on debasement consequently there is no pollution. Conclusion Pollution free procedures are making strides everywhere throughout the world. In this situation, enzymes rising as the best contrasting option to the contaminating textile preparing strategies. Enzymes are not just gainful from the biological perspective however they are additionally sparing a great deal of cash by decreasing water and vitality utilization which eventually lessen the cost of production.
