Fully Hydrolyzed PVA 1799 for Textile Warp Sizing
HOPEWAY PVA 1799 is a fully hydrolyzed polyvinyl alcohol designed for textile warp sizing. It provides high film hardness and abrasion resistance, reducing yarn breakage on high-speed looms. With low ash content, it prevents fabric staining and supports biodegradable desizing wastewater.
Key Selling Points
- High Film Hardness: Enhances warp yarn strength and abrasion resistance, reducing loom breakage rate.
- Low Ash Content: Prevents fabric staining and meets quality standards for export garments.
- Biodegradable: Desizing wastewater is biodegradable, supporting eco-friendly production.
- Improved Weaving Efficiency: Uniform sizing film reduces yarn shedding and breakage, improving air jet loom productivity.
- Consistent Quality: Stable viscosity ensures uniform sizing across batches.

Models and Options
PVA 1799 is available in powder form. Mesh size can be customized from 120-250 mesh to fit automatic sizing lines.
Materials and Structure
PVA is manufactured by alcoholysis of polyvinyl acetate (PVAc). The fully hydrolyzed grade offers higher crystallinity and water resistance, ideal for textile applications.
Applications
- Warp sizing for cotton and polyester yarns
- High-speed air jet loom weaving
- Embroidery water-soluble backing paper
- Non-woven fabric binder
Customization
Custom mesh size (120-250 mesh) and packaging. Free sizing formula optimization and remote troubleshooting are offered.
Case Study
Indonesian Textile Mill: A large integrated textile weaving factory purchases 850 tons of PVA 1799 annually for warp sizing. With custom 120-250 mesh, they achieved stable sizing performance, reduced yarn shedding, and improved air jet loom efficiency. Complete documentation ensured smooth customs clearance.
