Preparation method for ultraviolet-proof dyeing cloth

Abstract

The invention relates to a preparation method for an ultraviolet-proof dyeing cloth and belongs to the field of bast fiber fabric after-treatment. The technological process is as follows: singeing, enzyme cooling reactor, low-temperature enzyme oxygen bleaching, steam whitening, ultraviolet-proof waterproof treatment, baking, air soft finishing and shrink-proof treatment. For solving the technical problems in development of ultraviolet-proof waterproof bleaching fiber dyeing cloth, the invention strives to make technological breakthrough at the aspects of fabric pretreatment, ultraviolet-proof treatment, water-proof agent, bleaching color fastness, and the like, settles the contradiction between thread count and ultraviolet-proof effect of summer clothing material and the contradiction between ultraviolet-proof treatment and waterproof settlement, solves the problem of bleaching color fastness and the problem of material wearing comfort, maintains the original excellent characteristics and overcomes the defects.

Description

technical field [0001] The invention belongs to the field of post-treatment of hemp fabrics, and in particular relates to a preparation method of an ultraviolet-proof printing and dyeing cloth. Background technique [0002] With the development of industry, industrial waste gas leads to atmospheric pollution and ozone layer destruction. In the past, it was considered as a sunbathing for the pursuit of health, but now it has become a ruthless "sun killer" that threatens human health. The ozone layer is destroyed, the ultraviolet transmittance increases, and the probability of human beings suffering from skin cancer increases. Some experts predict that by the end of this century, the incidence of skin cancer will leap to the top of various diseases and become the number one killer of human beings. Therefore, people are vigorously researching ultraviolet radiation protection products, and now the sales of anti-ultraviolet cosmetics and daily necessities are increasing sharply...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the technical problems in the development of anti-ultraviolet and waterproof bleached hemp printing and dyeing fabrics, the present invention makes technical breakthroughs in the aspects of fabric pretreatment, anti-ultraviolet, water repellent, bleaching fastness, etc., and solves the contradiction between the sparse warp and weft density of summer clothing materials and the anti-ultraviolet effect. The contradiction between anti-ultraviolet and waterproof finishing, the problem of color fastness to bleaching and the problem of wearing comfort of the material make it not only retain the original excellent characteristics, but also overcome the above shortcomings
