Composition and Manufacturing Process of Non woven Fabric
Non woven fabric is a new type of environmentally friendly material, which is formed by various processing methods of fibrous polymer materials to form a fiber web. It has the advantages of softness, breathability, water resistance, stretch resistance, and non irritation. Its production process mainly includes fiber pretreatment, mixing, mesh forming, shaping, processing, and surface treatment. According to different fiber materials, production processes, and application fields, non-woven fabrics have various categories and properties.
UV protection
UV protection refers to the protection of ultraviolet rays, mainly including the protection of the skin and eyes.
Protection of the skin: Ultraviolet radiation, especially ultraviolet B waves, can cause skin burns, sunburn, and in severe cases, may even lead to skin cancer. Applying sunscreen is an effective UV protection measure to avoid the harm of ultraviolet rays to the skin. The SPF value on sunscreen represents its ability to protect against UVB ultraviolet rays, with higher values indicating stronger protection. In addition, some sunscreens can also provide protection against ultraviolet A waves.
Eye protection: Intense ultraviolet radiation can cause damage to the eyes, such as eye fatigue and inflammation. Long term exposure may also increase the risk of developing cataracts. Wearing sunglasses during outdoor activities can effectively reduce the damage of ultraviolet rays to the eyes. Choosing sunglasses with UV400 protection can provide more comprehensive UV protection.
The performance of non-woven fabric in UV protection
1. The hazards of ultraviolet radiation
Ultraviolet radiation is an important component of solar radiation, mainly including different wavelengths of ultraviolet radiation such as UVA, UVB, UVC, etc. Among them, UVA and UVB have the most significant impact on human health. Overexposure to ultraviolet radiation can cause skin dryness, aging, wrinkles, pigmentation, skin cancer, and other problems. Therefore, protection against ultraviolet radiation is crucial.
2. The UV resistance of non-woven fabric
Non woven fabrics have good performance in UV protection. According to professional testing data, general non-woven fabric materials can block over 90% of UVA and UVB ultraviolet rays. Moreover, non-woven fabric itself has advantages such as breathability and comfort, making it an ideal protective material. Of course, the specific protective capabilities need to be evaluated based on different products and production processes to ensure that the required protection standards are met.
3、 Verification based on actual protective effects
Non woven fabrics have a wide range of applications in the field of outdoor protection, such as sun protection clothing, sun protection hats, umbrellas, etc. The protective effect of these products has been recognized and praised by a large number of consumers, which indicates that non-woven fabrics do have certain protective capabilities in terms of UV protection.
Conclusion
In summary, non-woven fabric, as a new type of environmentally friendly material, has many advantages, among which UV resistance is one of the important safety guarantees. Although non-woven fabric cannot completely block ultraviolet rays, its good protective ability can meet the needs of many outdoor activities. Of course, in order to maximize the protective effect, readers still need to follow the correct protective methods and standards when using non-woven products.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
