Abstract

It can increase the tendency to fine-grained cellulose-solvent spun fibers. To keep the fibers under Management, which reduces the degree of polymerization by about 200 units or more, the appropriate methods of handling include severe bleaching. For example, the application of a clear liquid containing 0.1 to 10 percent by weight of Sodium hypolorite (Is available chlorine) to the fibers. Followed by steaming The fibers may be treated in a pre-dried form and the fibers managed by this fabrication process. Useful For example in the paper industry And the network at the hydro entangled Able to good fibers that increase the tendency of making Fine fiber Provides an independent Canadian 400 standard in the dispersion test. 30,000-150,000 Machine rotation cycle To disperse and reach the independence of the Canadian 200 standard in Diemnae test 50,000-200,000 Shredder rotation cycle
