At present, there are not many anti-ultraviolet fabrics on the market, mainly because people’s demand for them is not relatively large. Therefore, there are no particularly rich types of fabrics on the market. At present, the main UV-resistant fabrics are mainly polyester UV-resistant fabrics, nylon UV-resistant fabrics and UV-resistant fabrics. In fact, UV-resistant fabrics also include fabrics such as cotton, linen, silk and wool, polyester-cotton and what is nylon. These fabrics have a good ability to absorb and transform ultraviolet rays. Through the effects of reflection and scattering, all the ultraviolet rays absorbed by the fabrics are emitted, which prevents ultraviolet rays from harming human skin.
The fabric UV shielding finishing process is related to its ultimate use. For example, as a clothing fabric, it has high requirements for softness and comfort in summer, so it is better to apply the UV absorber by the exhaust method or padding method; if it is used as a decorative, household or industrial textile, its functional requirements are emphasized. The coating method can be selected; for the anti-ultraviolet finishing of the blended fabric, from a technical point of view, the exhaust method and the padding method are still better, because this type of process has great influence on fiber properties, fabric style, moisture absorption (water) and The effect of strength is small, and at the same time, it can also be carried out in the same bath with other functional finishing, such as antibacterial and deodorant, hydrophilic, and anti-wrinkle finishing.
There are two mechanisms of action of UV-resistant textiles: absorption and reflection. Correspondingly, there are two types of ultraviolet shielding agents: absorbers and reflectors (or scattering Jing). Absorbers and reflectors can be used alone or in combination.
Ultraviolet reflectors mainly use the reflection and scattering effect of inorganic particles, which can prevent the transmission of ultraviolet rays. Ultraviolet absorbers mainly use organic substances to absorb ultraviolet light, perform energy conversion, and release or consume energy in the form of heat energy or harmless low radiation. UV-resistant textiles processed by appropriate methods, no matter what fiber material, can achieve good UV-protection effect, and the influence of fabric thickness, color and other factors on UV performance is no longer important.
