Abstract

The invention relates to the method to use special biology enzyme (pectic enzyme, fibrin enzyme, lipase, albumen enzyme, lacquer enzyme, xylan enzyme, polysaccharide enzyme, and catalase) and environment-friendly effective surfactant to produce aid fitting the biochemical pretreatment of fibrin fiber, and its fabric, and its processing technology. The aid for short flow of zoology pretreatment made of a host of biology enzyme and environment-friendly surfactant can fit the short flow of zoology pretreatment of fibrin fiber and its fabric. The invention advances the quality of the production. At the same tie, it reduces pollution to the environment, and it achieves the process of pretreatment of fibrin fiber and its fabric with the interreaction with biology enzyme and surfactant. Moreover, thep rocess does little harm to the fiber and it has an effective removement of residue. Additionally, it is friendly to the environment.

Description

technical field [0001] The present invention adopts special biological enzyme preparation (pectinase, cellulase, lipase, protease, laccase, xylanase, dextranase, catalase, etc.) It is a kind of textile auxiliary agent and corresponding treatment process made by compounding agent, which is suitable for biochemical pretreatment of cellulose fiber or its blended fabric. The cellulose fibers or their blended products pretreated by this method can well meet the requirements of subsequent dyeing, printing or finishing. Background technique [0002] The dyeing and finishing process is the wet processing process of textiles, and has always been one of the major pollutant emitters in the industrial manufacturing and processing industry. One of the biggest negative impacts of dyeing and finishing on the environment comes from the traditional pretreatment of cotton fibers, yarns, fabrics or their blended products. [0003] This pretreatment includes the scouring process of heat treat...
