Also known as Vinylon. Using polyvinyl alcohol fiber as raw material, a synthetic fiber that is insoluble in water and similar in behavior to cotton is obtained by formaldehyde condensation treatment. The product name is Vinylon or Vinylon. In 1950, industrial production was officially launched in Japan. The strength and wear resistance are better than cotton, the polyvinyl alcohol fiber is 20% lighter than cotton, the moisture absorption is similar to cotton, and has quite good resistance to corrosion and sunlight, but its resistance to hot water is poor, elasticity is not as good as most synthetic fiber, and the dyeing property is also poor. The ultra-high molecular weight polyvinyl alcohol can be spun into high-strength and high modulus filamem, which can be used as automobile tyre cord. The products include staple fiber, long tow, filamem and solution dyed fiber. staple fiber and cotton blended fabrics can be used for clothing and interior decoration; pure textiles can be used as acid resistant, alkali resistant, oil resistant and corrosion resistant textiles and geotextiles; filament bundles can be directly made into stretch cut yarns for fishing nets, cables, canvas, filter fabrics, tyre cord, etc.
