64 Island sea-Island alkali reduction micro staple fiber ,there are 64 finest fibers,in one fiber which is finner than one-tenth of a human hair, so our fiber is the most finest one .this fiber is composed of two mutually compatible polymers, through special spinning equipment and using technology to be made. in this fine fibers ,64 sea island is one polymer, it is extremely evenly distributed in another polymer, just like islands in the sea, it can be Used in the reduction process in thealkali , to dissolve in the sea ingredients, so called alkali reduction sea -island staple micro fiber.
