Application of PVA in Warp Sizing

May 15, 2025 •

Polyvinyl Alcohol (PVA) is a widely used warp sizing agent valued for its excellent adhesion to both hydrophilic and hydrophobic fibers. It forms tough, abrasion-resistant films and blends well with other sizing agents like starch and polyacrylic acid, enhancing overall sizing performance. Fully hydrolyzed PVA offers strong adhesion but is difficult to dissolve and desize, while partially hydrolyzed grades are easier to handle but prone to foaming. Although PVA is non-toxic, its slow biodegradability limits its environmental appeal. Efforts are ongoing to improve its eco-friendliness and adapt its properties to modern high-speed weaving requirements. Despite these challenges, PVA remains one of the most effective and reliable textile sizing materials in use today.

Polyvinyl Alcohol (PVA) as a Textile Auxiliary Agent: Key Requirements in Warp Sizing and Stiffening Finishing

April 17, 2025 •

PVA serves critical roles in textile processing for warp sizing and stiffening finishes. For sizing, high-alcoholysis (≥99%), high-DP PVA (e.g., PVA-1799) strengthens cotton yarns, while partial-alcoholysis (~88%) variants suit synthetics. In stiffening, high-alcoholysis PVA provides permanent rigidity for heavy fabrics, and partial-alcoholysis types offer temporary stiffness for lightweight materials. Polymerization degree affects film strength (high DP) or flexibility (low DP). Optimal PVA selection by alcoholysis and DP balances weaving performance, fabric handle, and finishing durability, making it essential for efficient textile manufacturing.

Polyvinyl Alcohol (PVA): The Science Behind Its Diverse Applications

January 21, 2025 •

Polyvinyl Alcohol (PVA) is a versatile polymer with tunable properties based on its degree of polymerization (DP) and degree of alcoholysis (DH). High DP PVA results in high viscosity and strength, suitable for applications like textile sizing and high-strength adhesives. Low DP PVA offers low viscosity and fast dissolution, ideal for low-viscosity adhesives and cosmetics. Low DH PVA provides excellent water solubility, making it suitable for textile sizing and water-soluble films. High DH PVA exhibits excellent water resistance and chemical stability, used in food packaging and pharmaceuticals.
