What is PVA Fiber ?

What is PVA Fiber ?

High strength and high modulus polyvinyl alcohol fiber as the main raw material is dissolved , spinning , heat setting , cutting , packaging made of high strength and high modulus fibers .
The product has high strength, high modulus, low elongation , dispersion and good benefits , and acid, alkali , salt, abrasion, sunlight , corrosion , mildew, anti-moth and other characteristics, and cement affinity better, be applied to various reinforcing materials , widely used in building materials , safety nets and industrial textiles.

Use
Polyvinylformal fibers in the industrial field can be used to make canvas, tarpaulins, cloth , conveyor belts , packaging materials, uniforms, nets and ropes used offshore operations . High strength, high modulus filament reinforcing material can be used as conveyor belt , all kinds of hoses , adhesives and rubber shoes lining material , can also produce bicycle tire cord . Since this fiber cement alkali resistant , and with cement adhesion and affinity , and can substitute for asbestos- cement products reinforced material . Can be mixed with cotton , the production of clothing and interior products , but also can produce knitwear. However, heat resistance is poor , and the obtained fabric is not stiff, and can not be washed in hot water . In addition, non-woven fabric , paper , etc. also have use value.

Dissolve
Polyvinyl alcohol fibers can be blended with other fibers , then after dissolving in textile processing to obtain high-grade textile yarn , untwisted yarn may also be prepared with or without weft blanket . Can also be used as a binder used in papermaking, to improve the paper 's strength and toughness. In addition, also made special purpose clothing , surgical sutures .

Modified polyvinyl alcohol fibers
Important modified varieties are vinyl - polyvinyl alcohol graft copolymer fibers, China called dimensional polyvinyl chloride . It oligomeric polyvinyl alcohol aqueous solution as a dispersion medium , in the catalyst , the graft copolymer of vinyl chloride and polyvinyl alcohol ; from the resulting copolymer emulsion to emulsion spinning method ( see chemical fiber spinning ) spun fibers ; further consultation with polyvinyl formal fibers similar to post-processing , to obtain fiber products. It combines polyvinyl chloride fibers and polyvinyl formal fibers advantages.
