EM-R44 white bamboo charcoal 1.5D functional fiber, as a fiber material that combines high technology with natural environmental protection, is gradually attracting widespread attention in the textile industry. Its unique production process not only retains the natural advantages of bamboo, but also gives the fiber more functional characteristics. The thickness of EM-R44 white bamboo charcoal fiber is 1.5D and the length is moderate, which ensures its flexibility and stability in the textile process. The minerals and trace elements contained in the bamboo charcoal masterbatch itself can inhibit the growth and reproduction of microorganisms, thereby keeping the fiber clean and hygienic. After adding the bamboo charcoal masterbatch, the finished product will have stronger adsorption and deodorization functions. The honeycomb microporous structure that runs through the inside and outside is one of the core highlights of this fiber. This structure not only increases the specific surface area of the fiber, but also significantly improves its adsorption, decomposition and release capabilities, making the fiber in antibacterial, deodorizing, and adsorption of harmful substances. EM-R44 white bamboo charcoal fiber also has moisture absorption and breathability, which can quickly absorb and discharge moisture and sweat produced by the human body to keep the skin dry and comfortable. This characteristic makes the fiber very advantageous in the production of sportswear, underwear and other close-fitting clothing. At the same time, its far-infrared emission function can also promote blood circulation and has a certain health-care effect.
