Underwear processing factory: fabrics affect health and must be highly valued_News_Tengfei Technology

Cotton is warm and has good hygroscopicity, can absorb sweat from the skin, and is also very breathable. And soft close to the skin, no static phenomenon. processing factories feel that its disadvantage is that it is easy to wrinkle and shrink. Not very crisp and beautiful in appearance. Silk is composed of protein fibers, has excellent biocompatibility with the human body, is light and thin, and has a smooth surface. Its frictional stimulation coefficient to the human body is the lowest among all kinds of fibers, only 7.4%, and has an emollient effect. . It has better air permeability, moisture absorption, moisture dissipation and heat dissipation than cotton cloth. Under normal temperature, it can help the skin retain a certain amount of moisture and not make the skin too dry; when worn in summer, it can quickly dissipate the sweat and heat from the human body. It is warm in winter and cool in summer. Its disadvantages are that it is easy to wrinkle, easy to absorb, not strong enough, and fades quickly. Chemical fibers are popular for their bright, crisp and wear-resistant properties. Chemical fiber has the disadvantages of static electricity, hygroscopicity, air permeability, poor heat resistance, and easy deformation when exposed to heat. Using three different fabrics of cotton, silk, and chemical fiber to make pocket pants for experiments, and measure the humidity between the crotch respectively, the results: the relative humidity of cotton is 90%, the relative humidity of silk is 72%, and the relative humidity of chemical fiber is 97% . The heat dissipation of the three different fabrics is that silk is greater than cotton, and cotton is greater than chemical fiber. According to the physiological needs of the human body, the body temperature between the crotch should be 1-2 degrees Celsius lower than that of other parts of the body. This is because the temperature of the testis itself can produce sperm and hormones only when there is a temperature difference from the temperature in the body. If you wear chemical fiber pants, these functions will be inhibited due to high temperature and humidity. There may even be masculine feminization. It is precisely because silk has the best air permeability, moisture absorption, moisture dissipation and heat dissipation that silk underwear is widely popular abroad. Women have a lot of perineal secretions, and it is close to the anus, and there are many bacteria and other microorganisms. Among the three fabrics, chemical fiber pants produce the highest local moisture and heat generation. The local humidity and heat are more likely to cause the growth and reproduction of microorganisms such as bacteria. Therefore, women wearing chemical fiber pants are prone to urinary tract and vaginal infections. After the infection is treated, it is also easy to relapse. Also, because of the short urethra of women, the microorganisms of urinary tract infection can easily spread from the urethra to the bladder, and even to the renal pelvis, causing cystitis and pyelonephritis. Wearing chemical fiber seamless underwear manufacturer is harmful to the body. The fiber fabrics of chemical fiber seamless underwear manufacturer, such as elastic tights, nylon pants, nylon socks, and nylon polyester synthetic fiber fabrics, can release a small amount of 'plastic monomer' after being heated by the human body. Furthermore, when processing chemical fibers, softening agents, aerosols and antistatic agents are added, which are also potentially harmful to the human body. At present, the agriculture, chemical industry, and textile industries are all improving and innovating the fibers of various textile fabrics. It is believed that in the near future, better and more suitable fabrics for body shaping underwear will be on the market. For example, a fiber called tencel is made of wooden oars, which is as soft as cotton, and its water absorption and air permeability are better than cotton, and it is harmless to the human body.
