From Jiangyin Zhongjin Chemical Fiber Co., Ltd., a leading Chinese polyester fiber manufacturer, our recycled siliconized polyester staple fiber 1.5D × 51mm is a versatile sustainable raw material tailored for mid-to-high end spinning, filling and nonwoven applications. Made from 100% GRS certified recycled polyester bottle flakes via melt spinning, precision cutting and specialized silicone softening, it features a universal 1.5D fineness and standard 51mm cotton-type length for dual compatibility with yarn spinning and high-loft filling. It solves the core pain points of stiff handfeel and high static of ordinary recycled fibers, making it a cost-effective, sustainable choice for textile manufacturers, home textile producers and nonwoven fabric factories worldwide.
Pain Point: Global business buyers face stringent ESG mandates, carbon footprint checks and EU environmental regulations, with non-compliant materials risking market access barriers and brand reputation damage.
Solution: 100% GRS certified recycled polyester bottle flakes with end-to-end supply chain traceability.
Verifiable Evidence: Full batch traceability reports, compliant with OEKO-TEX® STANDARD 100 and EU REACH standards, enabling seamless sustainable procurement audits and global market entry.
Pain Point: Ordinary recycled polyester fibers cause high static, frequent end breakage, roller sticking and excessive wastage during processing, lowering production efficiency and raising manufacturing costs.
Solution: Specialized silicone oil finishing for ultra-low friction, paired with standard 51mm length for universal equipment compatibility.
Verifiable Evidence: Over 15% higher production efficiency, opening and spinning wastage controlled below 3%, fully compatible with ring spinning, rotor spinning and mainstream opening equipment.
Pain Point: Standard recycled fibers pill easily, clump after washing and have narrow application compatibility, forcing brands to stock multiple raw material SKUs and inflate inventory costs.
Solution: Stable 17%-21% crimp structure, balanced 0.22%-0.32% silicone oil content, and minimum 3.6cN/dtex breaking strength.
Verifiable Evidence: Excellent anti-static, anti-pilling and wash-resistant performance, no clumping or deformation after repeated washing, suitable for both spinning and filling to streamline raw material management.
