Many consumers agree with the pearl's beauty skincare effect, but there are still doubts as to whether the pearl and the pearl after the pearl and fiber are still functional, and whether the efficacy of the pearl disappears after the pearl fiber textile has been rubbed and washed several times during wearing. To this end, pearl fiber research group did a special washing and sweat immersion test. A certain amount of pearl fiber into the washing machine, respectively, washed with soap and water 5 times, 15 times and 30 times, each time for 9 minutes, and then dried to detect fiber content changes in the characteristic elements. Test showed that after 30 times the washing of pearl fiber content of the characteristic elements did not change significantly, you can prove that the active ingredient of pearl can not wash. In addition, a certain amount of pearl fiber was immersed in artificial sweat for 24 hours, 48 ​​hours and 72 hours, respectively, and then dried to detect changes in the content of fiber characteristic elements. Comparing the results before and after soaking, we can find that with the persistence of sweat immersion time, the contents of the characteristic elements in the pearl fiber show a regular decrease. Description Pearl particles react with sweat, some of which have been dissolved into active ingredients sweat. As the main component of the pearl particles is calcium carbonate, and calcium persulfate reaction generated calcium, the former is insoluble in water, while the latter can be dissolved in water, indicating that some of the dissolved active ingredients can be absorbed through the skin infiltration. Similarly, the research group will also put a certain amount of pearl fiber were placed in conventional concentrations of alkali and sulfuric acid for acid and alkali test. Tests show that after a certain concentration of acid-base solution treatment (such as printing or finishing), the effective content of pearl fiber did not change significantly. Experiments confirmed that the health care function of pearl fiber after washing several times or after dyeing process did not change significantly, and some of the active ingredients can be dissolved in sweat, absorbed through the skin infiltration, play a whitening skin, delaying skin aging Efficacy. Studies have shown that 50% of the population of women and 40% of men are sensitive to the skin, coupled with environmental pollution in recent years and other factors, the number of skin diseases are on the rise. Sensitive skin response to physical or chemical factors quickly, such as changes in the hot and cold climate, UV, water and pressure and other physical factors in response to the rapid; when the skin in direct contact with textiles containing free formaldehyde, harmful dyes Chemical materials, extractable heavy metals and excessive pH and other chemical factors, it is easy to make the skin irritated, causing redness, itching. The use of detoxification, skin care beauty function of pearl fiber textiles, you can make the skin surface micro-ecological balance, to avoid adverse factors to stimulate the skin from the pathogenic microorganisms. Therefore, pearl fiber is ideal for sensitive skin consumers. Pearl fiber is a new type of functional textile materials, with broad market prospects. At present, the pearl fiber textile products introduced into the domestic market have gradually expanded from the initial knitted underwear, bras, T-shirts and shorts to the fields of shirts, casual sportswear, jeans, socks and bedding, and the products are in short supply. Pearl fiber unique health care features also attracted the attention of foreign businessmen, it is understood that there have been the United States, Japan and the EU and other places merchants and pearl fiber manufacturers to purchase negotiations. We believe that mass production of pearl fiber textiles will soon be invested in the international market to better meet the needs of foreign consumers.
