PLA fiber-silk interwoven fabric

Abstract

The invention discloses a PLA (Polylactic Acid) fiber-silk interwoven fabric, which is prepared by the following steps: (1) pretreatment: 83dtexPLA / 88dtex PLA fiber-silk interwoven fabric is selected, put into a pretreatment solution, completely immersed, and maintained at 30-40 DEG C for 30-40 min, wherein the pretreatment solution is composed of 1% of trehalose, 0.05% of water-soluble chitosan and the balance of pure water; (2) compound enzyme treatment: the PLA fiber-silk interwoven fabric after pretreatment is immersed in a compound enzyme, wherein the process conditions of the enzyme treatment are as follows: 1 U / mL Bromelain, 6 U / mL phytase, 20-25 U / mL catechol oxidase, pH 7, temperature of 38 DEG C, time of 20-30 min, and a bath ratio of 1: 10; and (3) washing after-treatment: the PLA fiber-silk interwoven fabric after the enzyme treatment of step (2) is subjected to soaping treatment at 60-80 DEG C for 15-25 min at the bath ratio of 1:5.

Description

Technical field [0001] The present invention involves a corn fiber silk interweaving fabric and its preparation process, which is the field of textile fabrics. Background technique [0002] Polylactic Acid (PLA) is a fiber converted to a lactic acid by fermentation and spinning by corn, wheat and other starch -containing raw materials. It is also called corn fiber.It has the characteristics of biodegradation. The degradation product is carbon dioxide and water, so it is a new type of environmentally friendly fiber that can completely circulate completely.Because corn fibers have comfortable skin touch and feel, good hanging, good heat resistance and ultraviolet function, good use of good use.After the development of corn fibers in recent years, corn fiber has been applied to many fields such as webbing, clothing, and home textiles, and has been accepted and loved by more and more people. [0003] PLA fiber materials are compared with polyester fiber and have good clothing process...

AI Technical Summary

Problems solved by technology

[0006] Based on the technical problems existing in the background technology, the present invention aims at the shortcomings of the current corn fiber, and provides a new type of corn fiber silk interwoven fabric and its preparation process, so that the corn fiber silk interwoven fabric does not need pre-shrinking treatment after modification, and can be directly processed. It becomes heat-resistant and not easy to shrink. In addition, the hygroscopicity of the corn fiber is greatly improved, and it has a pearl-like luster, which is almost the same as that of real silk. Through a large number of experiments, the optimal parameters of the process were verified. At the same time, bromelain, phytase, and catechol oxidase were used to treat the corn fiber silk interwoven fabric. Such a process has not been reported.
