Abstract

The invention provides an enzyme pretreatment agent used for cotton fiber comprising a component a, a component b and a pH conditioning agent, and a treatment method of the pretreatment agent comprising the steps of desizing and refining. The required temperature is low compared with a traditional technology, so that the enzyme pretreatment agent is low in energy consumption and has relatively high economic benefit; the used treatment agent is little in environmental pollution, and accords with green and environmentally-friendly sustainable development viewpoints; and the enzyme treatment agent is mild in treatment mode and little in damage to cotton fabrics.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to an enzyme pretreatment agent and a treatment method for cotton fibers. Background technique [0002] The conditions for traditional cotton fabric pretreatment are high temperature and strong alkali, so the traditional cotton fabric pretreatment process has high energy consumption, heavy pollution, and great environmental pollution, which seriously restricts the development of the printing and dyeing industry. Biological enzymes have the characteristics of mildness, specificity and high efficiency, which have attracted the attention of the printing and dyeing industry earlier and are widely used in fabric pretreatment. However, a lot of practice shows that the effect of biological enzyme pretreatment is still not as good as that of traditional treatment. Therefore, it is more and more important to produce better enzyme preparations and optimize a more ideal biological e...
