Embodiment 1

[0020] Sample: Desized Cotton Poplin Fabric

[0021] a. Pretreatment: The pure cotton poplin after desizing is first treated in hot water at 95° C. for 10 minutes, with a liquor ratio of 1:50. After the treatment, it is washed with water at room temperature for 3 times, and then rolled dry (the scraping rate is 100%).

[0022] b. Pad the pretreated fabric with snail enzyme solution at a speed of 10m / min (enzyme concentration 5g / L, pH=6, temperature 50°C, level plus O concentration 2g / L), the padding method is double dipping Rolling, the excess rolling rate is 100%, stacking after rolling.

[0023] c. Stack the pure cotton poplin under the condition of unsaturated steam at 65°C for 45 minutes.

[0024] d. After stacking, wash once with hot water at 95°C for about 10 seconds, then wash three times with water at room temperature, and finally dry.

Abstract

The invention relates to a helicase which is a compound enzyme extracted from a snail crop or a snail digestive tract, the helicase mainly contains twenty kinds of enzyme including cellulose, pectinase, amylase, prolease and the like and is a byproduct in comprehensive utilization and development of snails, however, in the practical processing, the internal organs of the snail are always discarded, so that great waste of enzyme resources is caused. The helicase is a good compound enzyme system containing the pectinase, the amylase and the cellulose; the helicase which is a natural compound enzyme system is applied to a biological refining process of a cotton woven fabric to remove pectin, waxiness and other impurities in cotton fiber under the hydrolytic action of the helicase, therefore, the purposes of improving the wettability and the whiteness of the cotton fabric are achieved. The helicase is adopted for refining the cotton fabric, the helicase has the environment-protecting and energy-saving characteristics, the snail processing byproducts can be comprehensively utilized, the requirement for the current sustainable development is met, and the comprehensive development of the dyeing and finishing industry and the processing industry for snail agriculture products are facilitated.

Description

technical field [0001] The invention discloses a method for biological pretreatment of cotton woven fabrics by using helicase, which belongs to the technical field of cotton fabric dyeing and finishing pretreatment. Background technique [0002] In nature, snails mainly feed on leaves and shoots of plants. Therefore, during the long-term evolution process, biological enzymes that can digest various plant components have been produced in their bodies. In 1898, Biederman discovered that there are a large number of enzymes such as cellulase, hemicellulase, mannase and proteolytic enzyme in the digestive glands of snails. In 1922, Jiejia first isolated and extracted this mixed enzyme from the digestive gland of the snail, and called it "snail enzyme". In 1974, Chinese scientists also successfully separated and extracted helicase from the digestive glands of the brown cloud agate snail and the brown belt ringmouth snail respectively. At present, the industrial production of hel...
