Core Advantages
1. High viscosity forms continuous high-strength size film; less yarn breakage after repeated friction during weaving of heavy fabrics.
2. Stable forming of thick coating without cracking or peeling, uniform matte texture of paper surface.
3. Strong wrapping power for polyester & nylon filament, effectively reducing hair fibers and improving fabric smoothness.
4. Dense film formed as emulsion protective colloid, enhancing solvent resistance and oxygen barrier property of coating film.
5. Soluble in warm water at ambient temperature with higher production efficiency than BF fully hydrolyzed series.
