The use of pectinolytic enzyme preparations for the preparation of linen materials for dyeing

The most important in the technology of finishing of textile materials is the operation of preparing for coloring. Most of the operations of the finishing production of the textile industry are associated with chemical and physical-and-chemical effects on the fiber in quite harsh conditions - high temperature, aggressive chemical materials that have a destructive effect on the fiber-forming polymer. The actual task is to develop complex technologies for treating of flax materials to minimize the effect of chemicals on the fiber-forming polymer - cellulose, as well as to improve the environmental friendliness of finishing technologies. Biotechnology has particular practical importance, aimed at the use of enzymes of various activity in low temperatures and in neutral environments. Studies of the bioprocessing of flax fabrics with the enzyme preparation Pectinase were carried out, during which the optimal scheme of material preparation was chosen, rational technological regimes were determined: processing temperature - 50 °C, duration - 30 min, concentration of the enzyme preparation Pectinase - 3-4 g/l. Efficiency of use is proved by the results of studies of the capillary and strength properties of linen fabrics.
