64 Island Ding Island Alkali Reduction Island Short Fiber, in other words, a fiber that is one tenth thinner than a human hair contains 64 finer fibers. It is made by spinning two incompatible polymer materials through special spinning equipment and processes. Among them, 64 microfibers are one type of polymer, which is extremely evenly distributed in another type of polymer, just like islands in the sea, so it is named 64 Island Island Fiber. During the reduction process, alkali is used to dissolve the sea components in the fibers, hence it is called alkali reduced sea island short fibers.
