Synthetic Warp Sizing Agent & Polymer Sizing Compound
High-performance synthetic sizing agent and PVA replacement for polyester, cotton, and blended warp yarns to enhance tensile strength and weaving loom efficiency.

Synthetic Warp Sizing Agent & Polymer Sizing Compound
Warp sizing is the most critical preparation phase in woven fabric production. Synthetic Warp Sizing Agent is an advanced polymeric sizing compound specially engineered to coat warp yarns, significantly strengthening them against dynamic tensile stresses and abrasive friction on modern high-speed weaving looms (Air-Jet, Water-Jet, and Rapier).
Formulated with high-adhesion synthetic acrylic and modified starch polymers, our warp sizing agents act as a complete or partial replacement for expensive PVA sizing resins, lowering production costs while delivering superior film toughness and yarn elasticity.
Key Features & Benefits
- Superior Film Flexibility & Adhesion: Creates a smooth, resilient protective coating around spun and filament warp yarns, binding protruding fibers to reduce hairiness.
- High Anti-Abrasion Resistance: Eliminates warp yarn fraying and fuzz formation when passing through reed, heddle wires, and drop wires.
- Enhanced Tenacity & Elasticity: Significantly increases warp yarn breaking strength and preserves essential yarn elongation.
- Effortless Desizing: 100% water-dispersible formulation ensures fast, thorough removal during grey fabric washing and desizing processes without harsh chemicals.
- Eco-Friendly & Low BOD/COD: Biodegradable ingredients minimize wastewater treatment burdens in textile processing mills.
Applications in Weaving Industries
- Polyester & Blended Yarns: Sizing of PES/Cotton (T/C), PES/Viscose (T/R), and 100% spun polyester warp yarns.
- Cotton & Cellulosic Yarns: High-density weaving of fine-count cotton yarns for shirting, sheeting, and denim fabrics.
- Filament Weaving: Sizing of low-twist polyester and polyamide continuous filament warps.
- High-Speed Air-Jet & Rapier Looms: Optimized for weaving looms running at speeds up to 1000+ RPM.
