Problems solved by technology

For example, "Lyocell fiber fabric fibrillation problem" by Zhang Yongxia of Heilongjiang Construction Vocational and Technical College, Jiang Shaojun of Lanzhou University of Technology, Wu Ailing's "Discussion on Lyocell fiber fibrillation enzyme treatment technology", etc., the method is to use acid cellulase to The cellulose of Lyocell fiber is eroded and hydrolyzed. During the treatment process, the dosage of acid cellulase must be strictly controlled. 60 minutes and other factors, the operation is complicated and strict, and requires high technical level of workers; in addition, the weight loss rate of Lyocell fiber increases greatly after acid cellulase treatment, and its mechanical properties decrease. When the weight loss rate is 2.19%, the strength of Lyocell fiber decreases by 29.6%, the elongation rate decreases by 44%, and the initial modulus decreases by 19.9%. The treatment of the woven fabric will also change the shade of the fabric surface and affect its rubbing fastness

Abstract

The invention discloses a composite biological enzyme for a solvent method bamboo fabric, and a fabric surface cleaning method. The composite biological enzyme for the solvent method bamboo fabric is prepared through mixing the following components, by weight, 20-30 parts of an acidic cellulase, 7-15 parts of an enriched endonuclease, 4-8 parts of beta-glucosidase, 4-6 parts of sucrose, 4-6 parts of sodium chloride, and 35-45 parts of water. When the composite biological enzyme for the solvent method bamboo fabric is adopted to clean the surface of the solvent method bamboo fabric, the losses of the mechanic performances comprising the weight, the dry and wet fracture strengths, the fracture elongation rate and the like of the fabric are less, so the cleaning purpose of fibrillation removal is reached, and the color and the luster of the fabric are not influenced.

Description

technical field [0001] The invention relates to a composite biological enzyme for solvent method bamboo fiber fabric and a method for finishing the surface of solvent method bamboo fiber fabric. Background technique [0002] Solvent method bamboo fiber belongs to a kind of Lyocell fiber, known as the green fiber of the 21st century, it adopts the aqueous solution of N-methylmorpholine-N-oxide (NMMO) with a mass percentage of 50% to 80% to dissolve bamboo A kind of man-made cellulose fiber produced by spinning and reproducing cellulose, Chinese invention patent application publication CN101694019A discloses solvent method high wet modulus bamboo fiber and its preparation method. Wastes from the production of solvent-based bamboo fiber can be naturally degraded, and 99.5% of the amine oxide solvent in the production process can be recycled and reused without polluting the environment. [0003] Solvent-based bamboo fiber fabrics are used in clothing and home textile fabrics fo...
