PVA is the most efficient synthetic sizing agent, the advantages of warp sizing are:
1, PVA film has excellent strength and toughness, smoothness, wear resistance and adhesion to the fiber, and so on, the sizing effect is good, can improve the fine yarn high-density high-grade textile fabrics;
2, PVA on the fiber of the cohesion, protection is good, Can reduce the number of broken yarns during weaving, improve weaving efficiency;
3, PVA slurry is not easy to corrupt, the viscosity does not change after prolonged heating, so the sizing rate control is stable;
4, the use of starch slurry textile mill humidity to maintain in the 80~85%, and PVA slurry is the most suitable for 70~75% humidity, Therefore, it can improve the operating environment, improve the work efficiency,
5, reduce the sizing and weaving process of desizing phenomenon, maintenance plant cleaning, hydrophilic fiber (such as cotton, hemp) applicable to 17-99, 20-95, 17-95PVA, hydrophobic fiber (such as polyester yarn, glass fiber) applicable 15-88, 17-88, 20- 88PVA and so on.
Polyvinyl acetal fiber can be used in the industrial field to make canvas, waterproof cloth, filter cloth, transport belt, packaging materials, overalls, fishing nets and sea work cable. High-strength, high modulus filament can be used as a transport belt skeleton material, a variety of hose, adhesive tape and rubber lining materials, but also the production of bicycle tire curtain line. Because this kind of fiber can withstand the alkali of cement, and the bonding property of cement is good, may replace the asbestos as the reinforcing material of cement products. can be blended with cotton, the production of various materials and indoor supplies, but also the production of knitwear. But poor heat resistance, the fabric is not crisp, and cannot be washed in hot water. In addition, in the non-woven fabric, paper and other aspects also have the use value.
