30D hard cotton fiber Long Support Industrial Filling Textile Fiber,High Crimp Furniture Support Textile Raw Material
30D*64MM High Crimp Furniture Support Textile Raw Material
Our 30D*64MM rigid hard cotton polyester staple fiber is a professional heavy-denier high-support industrial filling fiber, specially developed for high-hardness anti-collapse rigid needle-punched hard cotton and furniture supporting nonwoven industry.
Different from common soft low-denier filling fiber, this 30D heavy denier fiber features rigid fiber body and superior bearing performance, serving as core raw material for high-support mattress, sofa base and automotive sound-insulation hard cotton.
- Equipped with exclusive high-density stereo crimp molding process for stable locked spiral crimp structure
- No rebound attenuation after long-term pressure bearing
- 64mm super-long fixed cutting length optimizes fiber interlocking force
- 100% virgin PET polyester raw material without recycled material doping
- Intrinsic anti-aging and mildew-proof formula
- Secondary constant-temperature heat setting treatment for ultra-low shrinkage
- Compatible with all mainstream needle punching machines and thermal bonding nonwoven production lines
