Problems solved by technology

[0003] For this reason, various energy-saving and environment-friendly pretreatment processes have been researched and developed in the textile industry in recent years, such as the currently disclosed patent documents: the method of "clean continuous production process for pretreatment of knitted fabrics" disclosed by the publication number CN1730808A carries out continuous pretreatment, including Process steps such as untwisting, primary feeding, stacking, primary washing, secondary feeding, steaming, secondary washing, and drying are characterized by cleanness and continuity, and good product performance, but the processing process is cumbersome and takes a long time. It requires high temperature and high energy consumption, so it is difficult to promote the production and processing of enterprises
[0004] Publication No. CN103046383A discloses "an enzyme oxygen one-bath cotton fabric low-temperature pretreatment method", using N-[4-(trialkylammoniummethylene)benzoyl]lactam chloride activator, hydrogen peroxide, annealing Slurry enzymes, scouring enzymes and supporting additives are characterized by mild processing conditions, low temperature, short process flow, energy saving, but long processing time
[0005] The purpose of the present invention is to provide a method of using biological enzymes to carry out continuous rapid one-bath desizing and scouring of cellulose-containing fiber textiles, so as to solve the problems of existing traditional high-temperature alkali pretreatment technology and existing biological enzyme desizing Bleaching technology has the problems of long time, high temperature, waste of resources and high cost in the treatment of cotton fabrics

Abstract

The invention discloses amethod for utilizing biological enzyme to conduct continuous and rapid desizing and boiling-off on a cellulosic fiber containing textile fabric and aims at solving the problems of lots of flows, long consumed time, high temperature and large fiber damage in the processing process of an existing desizing and boiling-off technology. Specifically, the method is lower in processing temperature, shorter in processing flow and higher in efficiency compared with a conventional alkali treatment method, the different between the method and a conventional enzyme treatment method is that desizing and boiling-off are completed through one bath, meanwhile an adopted continuous processing mode is quicker and more efficient, and the desizing rate, hair effect and other indexes can reach the conventional processing level after short-time processing. In the method for utilizing biological enzyme to conduct continuous and rapid desizing and boiling-off on the cellulosic fiber containing textile fabric, parameters including pH value, chromaticity, suspended matter and the like in wastewater are far lower than those of a traditional process, and the treatment burden of sewage is greatly reduced. In addition, various properties of textile fabrics subjected alkali treatment are kept through desizing and refining of the one-bath method.

Description

technical field [0001] The invention relates to the field of pretreatment of cellulose fiber-containing textiles, in particular to a method for performing continuous and rapid one-bath desizing and scouring on cellulose fiber-containing textiles by using biological enzymes. Background technique [0002] Cellulose fiber is one of the most consumed fiber varieties. It has excellent properties such as moisture absorption, breathability, warmth retention, and comfortable wearing. It is the most commonly used raw material for textile fabrics in the world. According to statistics, in recent years, cotton fiber accounts for about 40% of all fiber consumption in the world. The traditional desizing, scouring, and bleaching processes of cotton fabrics mostly use high-temperature concentrated alkali treatment. Not only is the process cumbersome, the energy consumption is high, the cost is high, and the environmental pollution is serious. At the same time, the strength of the cotton fab...
