AI Technical Summary

Problems solved by technology

The modal fiber has better hygroscopicity than cotton fiber, and it swells more in water, so it is dyed faster than cotton when dyed, that is, the initial dyeing rate is high. As a result, the color of cotton and modal blended fabrics will be different when dyed. Phenomenon
The industry has been using the addition of leveling agents and other chemical auxiliaries, high energy consumption and serious pollution, there is no energy-saving and environmentally friendly biological treatment method

Abstract

The invention relates to the field of dyeing, in particular to a composite boiling-dyeing one-bath enzyme and a dyeing method. The enzyme comprises the following components by mass percentage: 5-30 percent of acidic cellulase, 2-30 percent of alkaline pectinase, 0.1-20 percent of alkaline xylanase, 0.1-10 percent of mannose and balance of water. The method for formula treatment is a boiling-dyeing one-bath short-flow process, a refining process is omitted, and pretreatment and one-bath dying are enabled to be synchronously performed. The boiling-dyeing one-bath enzyme is sued for boiling-dyeing one-bath short-flow treatment, treated fabrics are dyed more deeply, the chromatic aberration of dyed cotton fiber and modal fabrics is small, horizontal marks which occur on the surfaces of the fabrics are remarkably reduced and the grade of chromatic aberration reaches grade 5 through national standard grey card chromatic aberration rating.

Description

technical field [0001] The invention relates to the field of dyeing, in particular to a composite one-bath scouring and dyeing enzyme and a dyeing method. Background technique [0002] At present, modal cotton fabrics are commonly used in the textile and garment industry. However, modal and cotton fibers have different adsorption properties to reactive dyes, and uneven dyeing occurs during dyeing. The industry has always used the addition of leveling agents and other chemical auxiliaries. , high energy consumption and serious pollution, there is no method for biological treatment. [0003] Cotton fiber is not only comfortable to wear, but also has better heat retention, but its hygroscopicity is lower than that of modal fiber. Modal fiber has good hygroscopicity. Under normal atmospheric conditions, the moisture regain is about 13%. Modal fabric is comfortable to wear and has a smoother feel than cotton, but its disadvantages are easy elongation, poor dimensional stability,...
