Problems solved by technology

[0002] When traditional cotton fabrics are dyed, the cotton fabrics are first bleached with caustic soda and hydrogen peroxide at a high temperature of 95°C for about 45 minutes, then neutralized and washed with water after bleaching, which takes about 120-150 minutes, and then dyed with reactive dyes. There are problems such as a large amount of waste water, a large amount of steam, and a high amount of electrolyte, and the damage of fabric fibers is relatively large, which seriously restricts the development of the dyeing and finishing industry

Abstract

The invention provides a multifunction composite biological enzyme with an excellent treatment effect. The multifunction composite biological enzyme is characterized by consisting of the following components in percentage by weight: 5-30% of pectate lyase, 10-20% of cellulase, 20-30% of an oxidizing agent, 5-10% of an alkaline agent A, 5-20% of an emulsifier and the balance of deionized water. Theinvention provides a method for adopting the multifunction composite biological enzyme for dye one-bath processing for pretreatment of cotton fabric. The method comprises the steps of 1, pretreatmentand dye one-bath, and 2, dyeing aftertreatment. As the biological enzyme technology is utilized, pollutant discharge is remarkably reduced, toxic and harmful substances are not generated, environmental protection is facilitated, and water consumption for cleaning fabric is also reduced. Compared with the traditional technology, the method achieves the purposes of saving energy and water and time,reducing consumption and emission.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing auxiliaries, in particular to a multifunctional biological enzyme and a one-bath processing method for pretreatment and dyeing of cotton fabrics. Background technique [0002] When traditional cotton fabrics are dyed, the cotton fabrics are first bleached with caustic soda and hydrogen peroxide at a high temperature of 95°C for about 45 minutes, then neutralized and washed with water after bleaching, which takes about 120-150 minutes, and then dyed with reactive dyes. There are problems such as a large amount of waste water, a large amount of steam, and a high amount of electrolyte, and the damage of fabric fibers is relatively large, which seriously restricts the development of the dyeing and finishing industry. In recent years, with the increasingly serious environmental pollution and the strict control of related policies, innovative dyeing and finishing technologies are imperative. I...
