Textile Enzymes

Biotechnology finds application in textiles to the ever change conditions of the ecology as well as the economy.
The use of enzymes in the textile industry is one of the most rapidly growing fields in industrial enzymology. The enzymes used in the textile field are used to remove the starch, degrade excess hydrogen peroxide, bleach textile, and degrade lignin. The use of enzymes in the textile chemical processing is rapidly gaining global recognition because of their Nontoxic & eco-friendly characteristics with the increasingly important requirement for textile manufacturers to reduce pollution in textile production.

BIO POLISHING

(Gentle effect by ACTIVOZYME solution)
Bio-polishing is a finishing process of textile that enhances the fabric quality by decreasing the pilling tendency and fuzziness of knitted fabrics. This finishing process is applied to the cellulose textiles that produce permanent effects by the use of enzymes.

Cellulase is a most popular and versatile enzyme used in textile wet processing for bio preparation, bio-polishing, and softening of cellulosic fibers. The surface modification of these bers to improve their outlook by removing superficial fibrils and microfibrils conferring cooler and softer feel, brighter luminosity of colors, and more resistance to pilling propensity using cellulases is known as bio-polishing. This is a biological process that employs the same cellulase action on the surface of the cellulosic materials. The process can be carried out at any stage of wet processing but most conveniently performed after bleaching. In addition, this is a permanent process and it keeps the fabric in good condition after repeated washing; consequently, products become more attractive to the customer.

De-sizing

Desizing is a process by which size materials remove from woven fabric. It is a part of the pre-treatment process in textile wet processing. This is the first wet processing in the textile finishing process used to remove sized materials from the warp yarn of woven fabric. This must be done before any subsequent wet processing of the fabric. Because of this, warp yarns are coated with sizing elements to reduce their frictional properties, to reduce broken yarns on looms, etc. After desizing, the absorption of the fabric increases. As a result, the fabric can easily absorb chemicals, dye molecules
As a consequence of the sizing, the warp threads of the fabric are not able to absorb water or Finishing agents to a sufficient degree. This means the first size must be removed before dyeing and finishing. Some types may be removed in a simple scouring process. But in most cases, chemical breakdown of the size polymer in a separate de-sizing treatment is necessary in order to obtain the desired of the final fabric. This will onsume a huge amount of water & different types of hazardous chemicals will be needed for the conventional de-sizing process. Huge amount of water will create a large amount of effluent & pressure on the environment will be higher An alternative eco-friendly de-sizing agents are in the form of enzymes. Sizing materials are removed from the fabric due to degradation of their polymer chain caused by the enzyme-like amylase for de-sizing due to their high efficiency and specificity, completely removing size without any harmful effects on the fabric. Amylase hydrolyze starch molecules to give divers products including dextrins and a progressively smaller polymer composed of glucose unit. These enzymes are commercially available with a Flexible range of pH & Temperature for improving the speed, economics & consistency of the process.

Peroxide removal

The bleaching with hydrogen peroxide is a fundamental stage that precedes the dyeing of cotton fabrics. Hydrogen peroxide an oxidizing agent leads to degradation of reactive dyes and may increase dye hydrolysis so that remaining peroxide residue on the fabric have a negative influence on the result of dyeing.

Thus the residues from bleaching baths must be removed from fabric and machinery before adding the dye. Usually successive washes of the fabric with water or chemical reducers diminish the residual bleaching agent concentration and improve dyeing. However, this involves the use of a big volume of water, a longer process time or the use of chemicals products noxious to the environment, resulting in additional costs and the generation of more effuents. An alternative to decrease the consumption of water, energy and time is the use of catalase which catalyse the decomposition of hydrogen peroxide and thus the elimination of its residues on cotton fabrics originated from the bleaching process.
