Problems solved by technology

In this patent, nano-zinc oxide and nano-titanium oxide are blended with polyester chips, and nano-zinc oxide and nano-titanium oxide are in direct contact with polyester fibers. Because nano-titanium oxide and nano-zinc oxide also have strong photocatalytic properties , long-term exposure to light will accelerate the aging of fabric fibers and affect the mechanical properties of fabric fibers
[0004] Chinese Patent Publication No. CN104452295 discloses a method for anti-ultraviolet finishing of cotton fabrics. Water-soluble titanate coupling agent is added to water, then nanometer zinc oxide is added, and sodium polyacrylate is added after ultrasonic vibration to obtain a finishing solution. Cotton fabrics Putting it in the finishing solution and padding treatment and then drying it to obtain an anti-ultraviolet cotton fabric. In this patent, the UV shielding component containing nano-zinc oxide is attached to the cotton fabric by the method of padding, but the method of dipping cannot be effective and fast on the cotton fabric. A sufficient amount of nano-zinc oxide UV shielding agent is attached to the surface of the fabric fiber, and the adhesion between the nano-zinc oxide and the cotton fiber is weak, which will cause the nano-zinc oxide to fall off from the surface of the cotton fiber during the washing process of the fabric, resulting in the damage of the fabric. Reduced UV protection

Abstract

The invention relates to the technical field of textile fabrics and discloses an ultraviolet-proof finishing method of a cotton fabric. The method comprises the following steps of S1, adding alginic acid and glutaraldehyde into polyvinyl acetate alcoholysis liquid, immersing the cotton fabric in a mixed solution for impregnation, and then carrying out thermal curing crosslinking to obtain pretreated cotton fabric; S2, modifying sepiolite with a silane coupling agent; S3, immersing the pretreated cotton fabric in a modified sepiolite suspension, and carrying out drying treatment on the cotton fabric after the reaction; and S4, adding nano zinc oxide and a polyethylene glycol dispersant into deionized water, stirring and mixing uniformly to obtain finishing liquid, putting the cotton fabricinto the finishing liquid, carrying out padding treatment, and taking out and then drying the cotton fabric to obtain the finished product. According to the cotton fabric prepared by the method, moreultraviolet shielding agents nano zinc oxide can be attached to the cotton fabric through a padding treatment method, the nano zinc oxide is not easily separated from the cotton fabric, and the cottonfabric has strong washing resistance.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an anti-ultraviolet finishing method for cotton fabrics. Background technique [0002] Ultraviolet light is an electromagnetic wave between X-rays and visible light. Its wavelength is concentrated between 200-400nm. According to the wavelength range, ultraviolet rays can be divided into UVA: 320-400nm, UVB: 280-320nm, UVC: 200- 280nm. Among them, UVC is absorbed by the atmospheric ozone layer and cannot reach the ground. The damage caused to human skin and various materials is mainly UVA and UVB. UVA has strong penetrating power, and long-term exposure to the skin will cause wrinkles and freckles on the skin; UVB can denature the nucleic acid or protein in the nucleus on the surface of the skin, produce erythema, form melanin, cause acute dermatitis, and excessive exposure can even cause skin damage. cancer. In recent years, with the destruction of the atmospheric ozon...
