Embodiment Construction

[0007] In actual production, in the process of fabric polishing and desizing, 90% biological enzyme + 1% pure water + 3% hydrogen peroxide decomposing agent Dioxy100L + 5% NaCl + other additives are used in the process of fabric polishing and desizing. The biological enzyme is cellulase. There is glucuronidase, its enzyme pH is 6.2, trypsin is 7.0, the active temperature of the enzyme is 40-80°C, trypsin is 40-50°C, and the fiber fluff is separated from the surface of the fabric by the enzyme to achieve smooth and soft fabrics At the same time, through the desizing reaction, the size on the gray cloth can be removed to ensure the quality of printed and dyed products.

Abstract

The invention provides a pre-treating clean production additive with the characteristics of high efficiency and short flow. The characteristic additive components includes: enzyme 90%, pure water 1%, hydrogen peroxide decomposer 3%, NaCl 5%, and other additives. The invention is mainly used in the fabric working procedures of polishing and desizing. The smooth and soft fabric effect can be achieved through the enzyme hydrolyzing fabric in order to enable the fabric fluff to be divorced from the fabric surface, and meanwhile the slurry on the grey clothes can be removed through desizing reaction in order to guarantee the qualities of printing and dyeing products. The dosages of water, electricity, and gas are saved, and the cost for processing waste water is reduced.

Description

technical field [0001] The invention belongs to chemical products, in particular to a pretreatment cleaning production auxiliary agent, which has the characteristics of high efficiency and short flow process. Background technique [0002] The pre-treatment process is one of the key processes in the printing and dyeing process. Its purpose is to remove the natural impurities contained in the fibers, the slurry applied in the textile processing, and the oil stains on the fibers by chemical and physical mechanical actions, so that the fibers can fully display their colors. Excellent quality, let the fabric fully display its excellent quality, make the fabric white, soft and permeable, meet the wearing requirements, and lay a good foundation for fabric dyeing, printing and finishing. Its traditional pretreatment process includes "singeing-desizing-scouring-bleaching" and other processes. The process route is long, the use of equipment is large, and various consumptions increase,...
