Product Details

Polyvinyl Alcohol PVA1799 Fully Hydrolyzed for Textile Warp Sizing

HOPEWAY CHEMICAL INDUSTRIAL CO., LIMITED offers PVA1799, a fully hydrolyzed polyvinyl alcohol (degree of hydrolysis 98-99%) with a degree of polymerization around 1700 and viscosity 22-30 mPa·s. This grade is specifically designed for cotton and chemical fiber warp sizing, providing high film hardness and abrasion resistance to reduce yarn breakage during high-speed weaving.

Key Selling Points

High Film Hardness & Abrasion Resistance: Fully hydrolyzed (98-99%) PVA1799 forms a tough, abrasion-resistant film on yarn, minimizing shedding and breakage during high-speed air jet loom weaving.
Low Ash Content: Low ash formulation prevents fabric staining, ensuring clean, high-quality finished textiles.
Easy Desizing: Water-soluble above 80°C allows simple and efficient desizing after weaving, reducing processing time and chemical use.
Consistent Viscosity: Stable viscosity (22-30 mPa·s) ensures uniform sizing application and predictable performance across batches.
Proven Performance in Indonesia: Trusted by a large Indonesian textile mill purchasing 850 tons annually for warp sizing on high-speed air jet looms, resulting in lower breakage rates and improved weaving efficiency.

Case Study

Indonesia Textile Mill: A large integrated textile weaving factory producing garment grey fabric and woven fabric for export clothing brands purchases 850 tons of PVA1799 annually. Applied to cotton and polyester warp sizing for high-speed air jet looms, the mill achieved stable sizing performance, reduced yarn shedding and breakage, and improved weaving efficiency by over 2 years of cooperation.

FAQ

What is the recommended dissolving temperature for PVA1799?

PVA1799 dissolves in water above 80°C. For optimal results, we recommend dissolving at 90-95°C with continuous stirring.

Can PVA1799 be used in cold water applications?

No, PVA1799 is fully hydrolyzed and requires hot water (above 80°C) for dissolution. For cold water soluble grades, consider our partially hydrolyzed PVA 1788 or 2488 series.

What is the minimum order quantity?

Our MOQ is 5 tons, with flexible delivery terms including FOB and CIF, and payment terms of 30/70 or L/C.

Do you provide technical support for textile sizing?

Yes, we offer free sizing formula optimization and online video troubleshooting for issues like sizing hardening and fabric shedding.

What documentation do you provide for import customs clearance?

We supply a complete set of COA, MSDS, TDS, and certificate of origin to ensure smooth customs clearance in your country.

How do you ensure consistent quality across batches?

We follow strict full-process quality inspection and maintain stable viscosity and low ash content to guarantee batch-to-batch consistency.

What is your shipping capacity for large orders?

With an annual PVA output of over 350,000 tons, we maintain constant stock and can prioritize container allocation during peak seasons to prevent production shutdowns.

Can you customize packaging?

Yes, we customize packaging according to customer requirements to ensure safe and efficient handling.
