Description

一种抗紫外棉织物的制备方法A kind of preparation method of anti-ultraviolet cotton fabric

技术领域technical field

本发明涉及一种抗紫外棉织物的制备方法,属于纺织技术领域。The invention relates to a preparation method of an anti-ultraviolet cotton fabric, belonging to the technical field of textiles.

背景技术Background technique

近年来,随着人们对生活水平的要求越来越高,在舒适地享受生活的同时,向大气中排放的大量的氟、氯化合物,使臭氧层遭到了日趋严重的破坏。到达地面的紫外线辐射量增多,对人体的伤害也越来越严重,因此对人体防护紫外线辐射的研究得到了重视。服装是人体最有效的保护工具,所以对纺织品进行抗紫外线整理很有必要。纯棉织物具有良好的吸湿性、透湿性,手感柔软,穿着舒适,自古以来都是人们的首选。然而,市场上的普通棉织物抗紫外线和抗菌性能不理想,需要对其进行功能性整理。In recent years, with people's higher and higher requirements for living standards, while enjoying life comfortably, a large amount of fluorine and chlorine compounds are discharged into the atmosphere, causing the ozone layer to be increasingly damaged. The amount of ultraviolet radiation reaching the ground is increasing, and the damage to the human body is becoming more and more serious. Therefore, the research on the protection of human body from ultraviolet radiation has been paid attention to. Clothing is the most effective protection tool for the human body, so it is necessary to carry out anti-ultraviolet finishing of textiles. Pure cotton fabric has good hygroscopicity, moisture permeability, soft hand feeling and comfortable wearing, and has been the first choice of people since ancient times. However, the common cotton fabrics on the market have unsatisfactory anti-ultraviolet and antibacterial properties and require functional finishing.

茶多酚,俗名抗氧化剂,从外观上来看,为白色粉末,可溶于乙醇、甲醇和丙醇,也可溶于水,但是不溶于氯仿。茶多酚可以抵御紫外线中一种波长的光线,阻断自由基的产生,能在一定程度上达到对紫外光损伤的防护和修复的目的,并且茶多酚有较强的收敛作用,对病原菌、病毒有明显的抑制和杀灭作用,因此,采用茶多酚对棉织物进行整理,可以一定程度上提升棉织物的抗紫外线和抗菌性能。研究发现,采用茶多酚处理后的棉织物,抗菌性能优良,但抗紫外性能的提升幅度仍显不够,并且整理后的棉织物抗皱性能较差。Tea polyphenols, commonly known as antioxidants, are white powders in appearance, soluble in ethanol, methanol and propanol, and soluble in water, but insoluble in chloroform. Tea polyphenols can resist a wavelength of light in ultraviolet light, block the production of free radicals, and achieve the purpose of protection and repair of ultraviolet light damage to a certain extent. Moreover, tea polyphenols have a strong astringent effect, which is effective against pathogenic bacteria. , virus has obvious inhibitory and killing effect, therefore, using tea polyphenols to finish cotton fabrics can improve the anti-ultraviolet and antibacterial properties of cotton fabrics to a certain extent. The study found that the cotton fabric treated with tea polyphenols has excellent antibacterial properties, but the improvement of anti-ultraviolet performance is still insufficient, and the wrinkle resistance of the finished cotton fabric is poor.
