In recent years, as people’s requirements for living standards have become higher and higher, while enjoying comfort, a large amount of fluorine and chlorine compounds have been emitted into the atmosphere, causing increasingly serious damage to the ozone layer. The amount of ultraviolet radiation reaching the ground increases, causing more and more serious harm to the human body. Therefore, research on human body protection from ultraviolet radiation has received attention. Clothing is a more effective protection tool for the human body, so it is necessary to carry out anti-ultraviolet finishing on textiles. Preventing ultraviolet damage to the skin while maintaining the original properties of the fabric has become an important issue in the textile dyeing and finishing industry. One of the topics. Since German physicist Ritter discovered ultraviolet light in 1801, people have been understanding and studying ultraviolet light for more than two centuries. Ultraviolet rays are an electromagnetic ray from solar radiation. The International Commission on Illumination (CIE) divides the ultraviolet spectrum into three different bands. According to the ultraviolet wavelength, it can be divided into: near ultraviolet LNA (315-400nm), far ultraviolet UVB (280-315nm) and ultraviolet Short UV LNC (100-280). Electromagnetic waves with wavelengths below 300nm in sunlight are almost absorbed by ozone in the atmosphere and hardly reach the ground. Therefore, most of the light that reaches the ground is near ultraviolet and far ultraviolet light. Appropriate exposure to ultraviolet rays is good for the body. It helps the body absorb calcium, strengthens the body’s non-specific immune function and the body’s defense capabilities, and promotes the secretion of certain hormones in the body. However, excessive exposure to ultraviolet rays can cause physical discomfort and even lead to many diseases. A large number of animal experiments have shown that UV-B ultraviolet radiation can damage the cornea and lens, causing eye opacity. Some studies have also shown that ultraviolet radiation can disrupt the human body’s immune system (such as causing people to produce melanin), suppress immunity, and worsen or increase diseases such as tuberculosis and herpes simplex. Excessive ultraviolet rays can cause serious damage to the skin in particular. The shorter the wavelength of ultraviolet rays, the more harmful it is to human skin. Short-wave ultraviolet rays can pass through the dermis, while medium-wave ultraviolet rays can enter the dermis. Excessive ultraviolet rays can damage the DNA in skin cells, causing sun spots and pigmentation. If the DNA damage of epidermal cells increases and exceeds its repair capacity, it can cause skin cancer.
