Non woven fabric is a type of textile formed by the combination of fibers through chemical, mechanical, or thermal means. It has many advantages, such as durability, lightweight, breathability, and easy cleaning. However, for many people, an important question is whether non-woven fabrics can resist exposure to ultraviolet radiation.
Ultraviolet rays
Ultraviolet (UV) radiation is a type of electromagnetic radiation with a short wavelength that can have harmful effects on the human body and objects. Ultraviolet radiation is divided into three types: UVA, UVB, and UVC. UVA is the longest wavelength ultraviolet light, which accounts for a large proportion of daily ultraviolet radiation and can penetrate clouds and glass. UVB is a medium wavelength ultraviolet radiation that causes greater damage to the skin and eyes. UVC is the shortest wavelength ultraviolet radiation, typically released through ultraviolet lamps or sterilization devices in space outside the atmosphere.
Materials and Structure
For non-woven fabrics, their ability to resist ultraviolet rays depends on their material and structure. At present, non-woven fabrics on the market are mainly made of materials such as polypropylene, polyester, nylon, etc. These materials themselves do not have good UV resistance, but their UV resistance can be enhanced through additives or special treatment methods.
UV resistant non-woven fabric
For example, many daily necessities such as sun umbrellas and sunscreen clothes use non-woven fabrics with UV resistance. These non-woven fabrics are commonly referred to as UV resistant fabrics, and they are typically produced using an additive called an UV resistant agent. This additive can absorb or reflect ultraviolet rays, reducing the damage of ultraviolet rays to the skin. When purchasing sun umbrellas or sun protection clothing, you can choose these non-woven products with anti UV function to enhance the sun protection effect.
Structure of non-woven fabric
In addition, the structure of non-woven fabric also affects its ability to resist ultraviolet rays. Non woven fabrics are usually composed of fiber layers bonded together, and the higher the density of fibers, the stronger the ability of non-woven fabrics to block ultraviolet rays. Therefore, when choosing non-woven fabric products, attention can be paid to the density and structure of their fibers to select products with better UV resistance.
Usage time and conditions
In addition, the ability of non-woven fabrics to resist ultraviolet rays is also related to the usage time and conditions. Over time, the anti UV additives in non-woven fabrics may gradually dissipate, thereby weakening their ability to resist UV rays. In addition, prolonged use of non-woven fabric products under sunlight can also expose them to ultraviolet radiation, gradually losing their ability to resist ultraviolet rays.
Matters needing attention
However, it should be noted that non-woven fabrics have limited resistance to ultraviolet radiation. Even non-woven fabrics with anti UV additives cannot completely block all UV rays. Moreover, for some special environments such as high mountains, deserts, and snowy areas, ultraviolet radiation is even stronger, and the resistance of non-woven fabrics may be weakened.
Conclusion
In summary, non-woven fabrics have a certain ability to resist ultraviolet rays, but this ability is limited and needs to be selected reasonably based on usage and environment. Whether using non-woven fabric products with UV resistance or other protective measures such as sunscreen and sunglasses, appropriate protection should be provided during outdoor activities or prolonged exposure to sunlight to reduce the damage of UV rays to the skin and eyes.
