Enzymes textile industry

Biopract provides technological products and processes for industry, agriculture, and environment. They not only produce technical enzyme preparations but also develop enzymes for applications in agriculture, food, and textile industry as well as in environmental technologies. On the later, bioremediation has been an area of service delivery from Biopract. Their activities regards microbial preparations for the bioremediation of organic contaminants (mineral oil (MKW), polycyclic aromatic hydrocarbons (PAH), benzene, toluene, ethylbenzene, xylene (BTEX), methyl-tert-butyl ether (MTBE), volatile organic hydrocarbons (VOC), and dimethyl sulfoxide (DMSO)). 

Bioremediation of food industry wastewater Bioremediation is a general concept that includes all those processes and actions that take place as an attempt to biotransform an environment, already altered by contaminants, to its original status. Laccase is a well-known enzyme in bioremediation because of its ability to degrade phenolic compounds (Morozova and others 2007). As mentioned for peroxidase, aromatic compounds, including phenols and aromatic amines, constitute one of the major classes of pollutants and are heavily regulated in many countries. This ability of laccases has been applied in different areas of both the food and textile industries, such as breweries and olive oil factories. 

Enzymatic desizing is one of the oldest nonfood applications of commercial amylases. Another type of enzyme, microbial cellulases, has developed within the textile industry as a tool for fabric finishing, in particular for denim garment finishing. Cellulases can achieve the fashionable worn look traditionally obtained by the abrasive action of pumice stones, ie, stone-washing. 

The application of enzymes in textile finishing becomes more and more important. Enzymes offer an ecologically benign alternative to common textile chemical processes, and totally new possibilities and chances to the textile finisher. Common applications of enzymes in the textile industry include improvement of softness, shine, and smoothness (biofinishing) creation of washout effects on blue denim through use of cellulases instead of pumice stones.

Build-up and Mode of Action of Enzymes for the Textile Industry... 

In the last few years, further applications for enzymatic processes in textile finishing were developed and - very importantly - the necessary suitable enzymes were found. Large-scale production of such enzymes led to price reductions, which in turn led to more applications, as enzymes were found to be efficacious in the textile industry. Another major reason why enzymatic processes are becoming more popular is the increasing importance of environmentally friendly technologies due to customers demands or restrictions by law.

Proteases are hydrolytic enzymes that catalyze the hydrolysis of peptide bond. Alkaline proteases are most commonly used in the textile industry as additives of detergents (Gupta et al., 2002) and can be used as for the surface modification of Nylon 6,6 fibers. Nylon 6,6 is a copolymer of hexamethylene diamine and adipic acid. Many proteases such as protex Gentle L, protex 40L, protex multiplus L, and protex 50FP were used to investigate changes in the nylon 6,6 polymer. Protease... 

RAPIDASE XC-T is an industrial grade enzyme preparation formulated to a standardized alpha amylase activity with water and sodium chloride. Alpha amylases catalyze the hydrolysis of alpha-1,4 glucosyl linkages in polysaccharides such as starch and glycogen. This enzyme product is used by the textile industry to improve the deslzing of cloth by hydrolyzing starch in the fiber coating. 

Industrial Uses. Papain is used in the leather industry to prepare the sides for tanning. Its proteolytic action removes some of the undesirable proteins which adhere to the hide and thus facilitates the subsequent tanning process. In the textile industry, the treatment of wool fibers with papain has been found to reduce the shrinkage from laundering. This appears to be caused by the abihty of the enzyme to destroy the elastic properties of wool protein. Because of its digestive action on protein, papain is used as a spot remover in the laundry and dry cleaning business. 

In the present context, biopolishing is used to denote enzymatic depilHng in an industrial context as carried out on unsewn fabric. There is a growing use of cellulase enzymes in the textiles industry.
