Fully Hydrolyzed PVA 2499 for High-Density Fabric Sizing
HOPEWAY PVA 2499 is a fully hydrolyzed polyvinyl alcohol designed for high-count and high-density fabric warp sizing. With a degree of polymerization around 2400 and a viscosity of 45–58 mPa·s, it forms strong, flexible films that reduce yarn breakage and improve weaving efficiency, especially for air jet looms.
Key Selling Points
- High film strength and flexibility: Degree of polymerization ≈2400 and fully hydrolyzed (98–99%) provide robust sizing films that withstand high-speed loom stress, reducing yarn breakage and shedding.
- Stable hot water solubility: Soluble in hot water, enabling easy desizing after weaving and reducing wastewater treatment burden.
- Excellent adhesion: Strong adhesion to cotton and polyester yarns improves yarn strength and abrasion resistance, enhancing weaving efficiency.
- Proven performance: In a large Indonesian textile mill, PVA 2499 consistently delivered stable warp sizing, lower defect rates, and higher air jet loom productivity over 2 years.
- Comprehensive technical support: Free sizing formula optimization, online video troubleshooting, and 24-hour response via WhatsApp from an exclusive sales manager.
