~Application Scope
This size is dedicated for polyester filament yarn, pure polyester yarn, and Terylene yarn with polyester content more than 60%.
Characteristics
Excellent adhesion performance
Having similar molecular structure and excellent adhesion performance with polyester, that the adhesion force better than that of PVA, acrylic ester and modified starch, etc
Better water-soluble
Having a good solubility in water above 80℃, no precipitation, no crust. Having a good miscibility with the starch, PVA, acrylic ester, no precipitation, no stratification.
Low viscosity and good stability
Adapt to the high concentration, high pressure, low viscosity sizing process. Easy to get good penetration, fiber cohesion, hairiness appressed.
Good sizing film
Firm, smooth and transparent, the sizing film disconnected uniformly in lease with little regeneration yarn hairiness. Effectively reduce the rate of warp breakage and improve the loom efficiency.
Cost effective
Providing the quality of weaving is satisfied, the sizing was used in an 0.5 times of PVA dosage.
Green and Eco friendly
Degraded by alcohol, water, alkali, light and microbe. The performance of degradation is better than PVA and the dosage is 0.5 times of PVA in weaving to reduce the cost of sewage treatment.
