nature : also known as crack fiber membrane, tensional fiber, fiber or flat yarn tear. Polymer films will be made after a certain interval to pass the turret, cut into a width of 2.5 to 6 mm and a thickness of 20 to 50 mm of uniaxial tensile Chen Shui-bian, Chen Shui-bian of the uniaxial tensile withstand, and the impact fibrillating effect along the direction of the tensile strength than the original film is greatly improved , and perpendicular to the direction of the tensile strength there has been much reduced, will be automatically split, and then fine fibrillation can be made from 0.3 to 1.5 cows / special (3 to 5 Caledon / day) of the fibers. Using this method made of polypropylene flat yarn, the relative density of 0.9, which can be used to create kits tying, knitting bags, carpets substrate and certain other decorative fabrics.
