Problems solved by technology

Although ordinary fabrics have a certain anti-ultraviolet function, they are far from meeting people's needs for anti-ultraviolet rays. Therefore, the research on the anti-ultraviolet finishing of fabrics is becoming more and more important.
[0003] There are many kinds of anti-ultraviolet agents on the market, but the effect is only a single anti-ultraviolet property, which cannot be washed or dry-cleaned to a certain extent, and the feel and appearance of textiles after anti-ultraviolet treatment are greatly affected.
Even some UV rays can sometimes decompose and destroy the fiber structure of the fabric, reducing the durability and washability of the fabric

Abstract

The invention discloses a finishing method for an ultraviolet-resistant water-proof anti-bacterial fabric. The finishing method comprises the steps that (1), ferulic acid, sinapic acid and p-coumaricacid are mixed in a certain proportion to prepare an ultraviolet-resistant water-proof anti-bacterial finishing solution; (2), the fabric is immersed into the ultraviolet-resistant water-proof anti-bacterial finishing solution, and after two dipping and two padding, negative-pressure flash explosion and drying are conducted in sequence; (3), the dried fabric is immersed into an ozone saturated laccase solution for catalytic crosslinking, and drying is conducted again; (4), the fabric obtained after being dried again is immersed into a methyl alcohol solution containing lipase, a methyl esterification reaction is carried out, and drying is conducted. The finishing method is suitable for various fabrics, the finished fabric has significant ultraviolet-resistant, water-proof and anti-bacterial effects, the finished fabric can be used as a medical material, a textile and garment material, an anti-bacterial material and the like to be widely used in the fields of textile industry, medicineand health care, biomedicine and the like.

Description

Technical field [0001] The invention relates to the field of textile engineering, in particular to a finishing method for anti-ultraviolet, waterproof and antibacterial fabrics. Background technique [0002] In recent years, the ozone layer in the atmosphere has been severely damaged, and the ultraviolet rays reaching the ground have greatly increased. Ultraviolet rays will not only reduce the human body’s immunity, but also cause human skin diseases, and even worse, make people suffer from skin cancer. Although ordinary fabrics have certain anti-ultraviolet functions, they are far from meeting people's needs for anti-ultraviolet rays. Therefore, the research on anti-ultraviolet finishing of fabrics becomes more and more important. [0003] There are many kinds of anti-ultraviolet agents on the market, but their effect is only relatively single anti-ultraviolet. They cannot be washed or dry-cleaned to a certain extent, and the feel and appearance of textiles after anti-ultraviolet ...
