Vinylon fiber chemical called polyvinyl alcohol, and its strength is lower than PET, the strength of only 5.32-5.72Cndtex, elongation 12-25%, poor flexibility, poor shape fabric, good wear resistance, durability cotton than 1-2 times, but one of the greatest advantages is that we can withstand the role of alkali and good moisture absorption, easy to combine with the rubber, rubber industry, with good use of materials, its drawback is that temperature lower temperature of 100 degrees there is contraction acid intolerance.
