PVA China polyvinyl alcohol 0588,0599,

PVA is usually processed in the form of aqueous solution. Since the solution is slightly acidic (pH 5~7), vessel

should be made of materials, which will not contaminate the solution with corrosive material or rusts. Stainless

steel vessel, enameled containers or polyester tanks are recommended.

The specific gravity of PVA is ranging from 1.26 to 1.31, which is heavier than that of water. Low agitation speed

or unfavorable agitating condition sometimes causes coarse particles to precipitate and to block the outlet of

the dissolving tank. Hence, a flush valve or tank valve is recommended to be installed in the bottom of the vessel to prevent the particles from blocking the discharge line.

■ Low add-on. HOPEWAY PVA exhibits high adhesion and cohesion, especially when compared with nature products,

thus enabling sizing to be carried out with greatly reduced amount, and greatly reducing abrasion on the sizing machine and loom.

■ High weaving efficiency.Yarns sized with PVA show excellent weaving efficiency with few loom stops.

■ Stable solution viscosity. PVA solution is real solution as oppose to the colloidal suspension formed with

starch. Solution of PVA can be held at elevated temperatures for days without viscosity degradation.
