Industry Applications
1. Paper & Board Wet-End & Ply Bonding
Fourdrinier wire spray addition to enhance fiber/filler retention, reducing white-water solids by up to 30%.
Ply-bond improvement in duplex and multi-layer boards, boosting internal bond strength by up to 25% and preventing delamination under load.
2. Textile Warp & Fabric Finishing
On-warp yarn sizing sprays in slasher frames (patent US3068120A), enhancing abrasion resistance and reducing yarn breakage by 20%.
Garment and quilting fabric finishing, providing controlled stiffness and crispness for ironing, cutting, and sewing.
Key Benefits
- Stable, Clog-Free Spraying : Brookfield viscosity ≤ 2,000 cP at 5% (25 °C), no nozzle blockages for 8+ hr runs.
- Enhanced Retention & Bonding : +30% fines/filler retention; 100% fiber-tear ply adhesion for paper; +20% yarn strength for textiles.
- High Efficiency & Cost Savings : Effective at 0.2–0.5 kg/ton in paper; 5–10 g/kg in warp sizing—reducing additive spend by up to 20%.
- Rapid Film Set & Fabric Finish : Spray-on fabric starch solution achieves crisp ironing results in < 5 min, improving cutting accuracy and seam quality.
- Easy Integration : Cold-water dispersible, compatible with existing spray systems and process controls.
