Cold Reflection On The Price Of Melt Blown Fabric: After The Mask Era, Antibacterial Fiber Materials Will Become Popular.

During the epidemic period, masks were important protective equipment, and the market demand increased sharply. With the expansion of masks production lines all over the country, the demand for melted fabrics called masks is increasing.

Due to the production of a melted spray cloth line from 10 to 1 years, it also leads to the shortage of melt blown fabric at present. It is understood that after the outbreak, the original price of 10 thousand ~3 yuan of melted cloth has increased by at least 10 times, and some middlemen even ask for 400 thousand yuan / ton. Especially for melted spray that meets the medical standard, "money is not available now".

According to the national development and Reform Commission, the current utilization rate of masks in China has reached 110%, Nissan can reach 110 million, and daily output reaches 116 million. In addition to 30 provinces and municipalities outside Tibet, China has gradually put on the mask production line, and new masks production lines will continue to go into operation. The head of China Textile Business Association said that the market demand for melt blown fabrics will also increase in the future.

With the gradual control of the epidemic, what will happen to the mask demand? In the public's demand for antibacterial and bactericidal products, what new requirements will be put forward for textile development and production? Wang Zunyuan, general manager of Qingdao Xinwei textile company, suggests that the application of antibacterial materials will become the norm.

According to Wang Zunyuan, to achieve permanent antibacterial, it is mainly through the antibacterial material itself. "Generally speaking, antibacterial is a general term for bacteriostatic and bactericidal effects. The killing of microbial nutrients and propagules is called bactericidal action, and the role of preventing or inhibiting microbial growth and reproduction is called bacteriostasis. Because of its porous object shape and the chemical structure of macromolecule polymer, the textile fabric is a good parasitic body for microorganism to survive and reproduce. Antibacterial fabrics have different degrees of antibacterial action, which can prevent bacteria from propagating, reduce the risk of their re transmission, and eliminate the peculiar smell caused by bacteria, so as to keep the fabric clean and tidy.

At present, the antibacterial testing standards have different standards, such as American Standard and national standard. They are mainly classified into two categories: one is to monitor specific values, for example, the antibacterial rate reaches 99.9%; the other is to monitor the value, for example, the value is 2.2, 3.8, etc. Usually, the value reaches over 2.2 or the antibacterial rate reaches over 90%, that is, the test is qualified.

Wang Zunyuan believes that the production of antibacterial textiles from antibacterial fibers will be the main direction of future development. Antibacterial fibers can be roughly divided into two categories: one is to add antibacterial agents to the modified antibacterial fibers made from fibers; the two is natural fibers with antibacterial function, such as some hemp, bamboo fiber, chitin and so on. The former has excellent antibacterial effect, and the latter has antibacterial effect, but its bacteriostatic rate is not high.

It is understood that the modified antibacterial fiber is made of physical modification of polyester or nylon, and the addition of metallic silver to filament or yarn in fiber. For example, silver ion antibacterial fiber (polyester, nylon, etc.) can achieve antibacterial effect according to the principle of silver ions inhibiting the formation of bacterial cells. The antibacterial activity of silvery fiber, silver ion antibacterial fiber developed by Xinwei textile, to Staphylococcus aureus, Escherichia coli and Candida albicans is over 99%, and has good antibacterial effect. At the same time, on the basis of satisfying antibacterial function, The filament is made of "ten" shaped section and short fiber with "three leaves" section to form pore grooves between fibers, providing capillary pores for sweat and moisture diversion, which is conducive to moisture absorption and sweating, and improves fabric comfortableness.

Nylon based copper ion fibers are strongly embedded in fiber molecular structure because of their strong copper ions. Therefore, they have strong, lasting antibacterial, deodorant and self cleaning functions. Their antibacterial effect is obviously higher than that of other antibacterial fiber products. The new silk fabric developed by Xinwei textile is copper ion deodorizing antibacterial fiber. After washing for 50 times, its bacteriostatic rate to Staphylococcus aureus, Escherichia coli and Candida albicans is over 99%, and has good antibacterial effect. After washing 10 times, the deodorizing effect of ammonia, odorant, acetic acid, isovalerate, 2- nonenal, and indole odor are all higher than the standard value, which has good deodorizing effect. Fruit.

The plant traditional Chinese cotton fiber is a cooperative project between Qingdao Xinwei Research Institute and Qiingdao University, and is a patent for Professor Hu Sheng. As one of the four natural fibers (cotton, wool, silk and hemp), cotton fiber has been favored by many people because of its unique properties such as softness, warmth and comfort. But cotton fibers also have their own shortcomings which are not to be overlooked, such as poor wrinkle resistance, easy to wear, easy to mold, easy to breed bacteria, mites, good durability and single purpose.

The functional modified cotton is made from cotton plants with the active ingredients extracted from plant Chinese medicine. It is used to modify the cotton fiber and plant the effective components of traditional Chinese medicine into cotton fibers, giving cotton fibers many functions such as antibacterial, anti mite, anti itch, anti mould and so on, so that ordinary cotton fibers have high power or versatile functions, and the products are green, environmentally friendly, harmless to human body and good washability. After 20 times of washing, the bacteriostatic rate (Staphylococcus aureus) reached 92.4%, the mould resistance level reached 1, and the repellent rate of the mites was more than 78%.
