Abstract

The invention relates to a manufacturing method of fabrics. Highly active refined enzyme one-step-one-bath preprocessing method is adopted for a polyester-cotton fabric, the method has the following steps: following solutions are adopted, a chemical of 50-60 DEG C is heated up, a piece of dry fabric cloth to be processed is sent to working solutions for padding with dispersed phase holdup of 80-100%, then the dry fabric cloth is steamed for 60-75 min under the temperature of 98-102 DEG C, dried after being washed by hot water under the temperature of 95 DEG C to 98 DEG C at first and then by water under the temperature of 60 DEG C to 65 DEG C, thus the one-step-one-bath preprocessing method is competed. The working solutions used in the method has mixture ratio as follows: hydrogen peroxide (100%) 12-14 gram / liter; highly active refined enzyme 25-30 gram / liter; refined osmotic agent 5-8 gram / liter. The highly active refined enzyme preprocessing method combines refining, stabilizing, infiltrating, emulsificating, chelating into a whole, hydrogen peroxide stabilizer and alkali and the like are not needed to be added, thus ensuring stability and uniformity of preprocessing, not only saving sewage treatment expense but also reducing sewage treatment pressure.

Description

1. Technical field:

[0001] The invention relates to a fabric production method, in particular to a pretreatment method for polyester-cotton fabrics. 2. Background technology:

[0002] According to the "Eleventh Five-Year" development outline of the textile industry, by the end of the "Eleventh Five-Year Plan", my country's textile printing and dyeing industry will reduce energy consumption and environmental protection by 10% compared with 2005. The annual reduction is 20%, and the sewage discharge per unit output value is 22% lower than that in 2005. As we all know, the printing and dyeing industry has always been one of the largest users of water consumption and sewage discharge. The textile industry's sewage discharge accounts for 35% of the total industrial wastewater, and the printing and dyeing industry's wastewater accounts for 80% of the national textile wastewater discharge, and the average reuse rate is only 10%. At present, the water consumption per unit product o...
