Fully Hydrolyzed PVA 1799 for Textile Warp Sizing High-Speed Looms

This is a fully hydrolyzed polyvinyl alcohol grade 1799, featuring a high degree of hydrolysis and polymerization for excellent film hardness and abrasion resistance. It is specifically designed for textile warp sizing of cotton and polyester yarns, reducing breakage and improving weaving efficiency on high-speed air jet looms. Our PVA 1799 has been consistently supplied to a large Indonesian textile factory for over two years, supporting monthly container shipments.

Key Selling Points

High Film Hardness: Provides robust yarn protection, reducing shedding and breakage during weaving.
Excellent Abrasion Resistance: Withstands friction on high-speed looms, extending yarn life.
Low Ash Content: Minimizes fabric staining and improves final product quality.
Easy Desizing: Fully hydrolyzed grade allows efficient removal by hot water washing, biodegradable.
Consistent Sizing Performance: Stable quality ensures uniform film formation and predictable results.

Models and Options

This product is available under model PVA 1799. For textile applications, we also offer PVA 2488 (partially hydrolyzed) for specific requirements. Custom mesh sizes (120–250 mesh) can be provided to match your automatic sizing line.

Materials and Structure

PVA is manufactured by alcoholysis of polyvinyl acetate (PVAc), resulting in a water-soluble polymer with excellent film-forming properties.

Applications

Cotton warp sizing
Polyester warp sizing
High-speed air jet loom weaving
Yarn lubrication and protection

Customization

We provide adjustable mesh size (120–250 mesh) to fit continuous sizing lines. Our textile technical team offers free sizing formula optimization and online troubleshooting.

Case Study

Indonesian Textile Factory: A large textile weaving factory in Indonesia annually purchases 850 tons of PVA 1799 for cotton and polyester warp sizing. With our product, they achieved reduced yarn shedding and breakage, leading to higher weaving efficiency. Uniform sizing film and flexibility reduced fabric defects. We supplied complete export documentation and provided quick technical support via WhatsApp.

FAQ

What is the difference between fully and partially hydrolyzed PVA?

Fully hydrolyzed PVA has a hydrolysis degree of 99%+ and requires hot water to dissolve, while partially hydrolyzed PVA dissolves in cold water. Fully hydrolyzed grades form stronger films and are often used in textile sizing.

Can PVA 1799 be used for cold water sizing?

No, PVA 1799 requires hot water (80-95°C) for efficient dissolution. If cold water solubility is needed, consider partially hydrolyzed grades like 2488 or 1788.

What is the MOQ?

MOQ is 5 tons.

How do you ensure consistent quality for large orders?

We have a centralized testing lab and strict quality control. Each batch is tested for viscosity, degree of hydrolysis, and ash content before shipment.

Do you provide technical support for sizing formulas?

Yes, our textile technical team offers free formula optimization and remote troubleshooting for common issues like sizing hardening or fabric shedding.

What payment methods do you accept?

We accept T/T and L/C (30/70).
