Problems solved by technology

However, in the prior art, when biorefining is carried out by pectate lyase and damustease, etc., they are generally treated separately, so as to prevent the interaction between pectate lyase and damustease, and then separate treatment will lead to Further increase cost and further consume time and energy

Abstract

The invention provides a dyeing method suitable for cotton fiber textiles. The dyeing method comprises the following steps: S1, pretreating the fiber textiles in water at 42-45 DEG C for 20-30 minutes; s2, adding neutral liquid pectate lyase, and keeping the temperature for 10-15 minutes; s3, the pH value is adjusted to 5.5-5.8, and the temperature is increased to 50-55 DEG C; s4, soft light protease is added, and heat preservation is conducted for 40-60 minutes; s5, then adding refined protease and hydrogen peroxide, raising the temperature to 95 DEG C, and keeping the temperature for 20-30 minutes for inactivation treatment; and S6, after cooling, carrying out water washing and normal dyeing processes.

Description

technical field [0001] The invention relates to a dyeing method suitable for cotton fiber textiles. Background technique [0002] Cotton textiles generally need to undergo a traditional oxygen bleaching process before dyeing, which is not only costly but also time-consuming and energy-intensive. The traditional alkaline cooking process usually results in stains, color spots, color differences, etc. due to unclean pre-treatment cooking and a large amount of pectin residues. At present, biorefinery can be carried out by pectate lyase and soft light protease. However, in the prior art, when biorefining is carried out by pectate lyase and soft light protease, they are generally treated separately to prevent mutual influence between pectate lyase and soft light protease. Further increase the cost and further time-consuming and energy-consuming. SUMMARY OF THE INVENTION [0003] The present invention provides a dyeing method suitable for cotton fiber textiles, which can effec...
