Water Soluble PVA Fiber
Water soluble PVA fiber is also called Water-soluble PVA short cutting fiber.The cotton-like synthetic fiber is made
from polyvinyl alcohol through wet spinning,heat treatment,crimping in warm water and oiling.The product has
good physical and mechanical properties such as corrosion resistance,acid and alkali resistance and good dry heat
stability.The remarkable characteristic is its total dissolving in water at a range of temperature. It will greatly improve
the fabric style and grades.Water soluble non-woven fabrics can be used for computer embroidery cloth,clothing,
medical operation operation cap,operation towel disposable cloth;the pure spinning cloth can be used for medical non-stick gauze.

High Strength And High Modulus Polyvinyl Alcohol Fiber
(HSHM PVA FIBER )
High strength and high modulus PVA fiber (HSHM PVA FIBER )is one kind new product of vinylon,which is mainly
made by PVA.It is of high strength,high modulus,acid-proof,alkali-proof,abrasion resistance and sunlight resistance,
thus it is much better than the other products in general.With these excellent properties,it has a wide application
in industry fabric,building reinforcing materials,package materials,ropes and meshes, especially mainly
used as a substitute material for asbestos to reinforce the cement products.
