PVA USE FOR Textiles
Polyvinyl alcohol is widely used for textile warp sizing. Polyvinyl alcohol exhibits high adhesion, strong leather film and good resistance. Partially hydrolysis grades shows strong adhesion and excellent film-forming ability, creating a continuous and uniform protective layer to enhance yarn performance. Fully hydrolysis grades PVA benefits in textile finishing operations.
Weavability
PVA use for textiles can maintain stable viscosity, with excellent acid/alkali resistance and antimicrobial properties, ensuring consistent and reliable application. In the desizing process, polyvinyl alcohol can be completely removed, shortening the production cycle. The desizing process does not damage the yarn, preserving yarn quality—ideal for high-value textiles. PVA use in textiles is superior to other materials, like starch, because they are stronger and provides the required protection.
Superior Film-Forming Properties
The film-forming characteristics of polyvinyl alcohol make them ideal for yarn sizing. Polyvinyl alcohol forms a uniform, tough film on the yarn surface, improving tensile strength—cotton yarn tensile strength can be increased by up to 40%.
Recoverable and Environmentally Friendly
PVA shows remarkable environmental friendly advantages. COD levels in effluent are reduced by 70% when using PVA size, with lower environmental impact and lower wastewater treatment costs. PVA is readily biodegradable, reducing wastewater treatment expenses by 50%.
