Jiangyin Zhongjin Chemical Fiber (JZCF)’s Virgin 3D Hollow Conjugated Polyester Staple Fiber 3D×64mm is a high-performance filling material exclusively engineered for high-end filling scenarios, spun from 100% brand-new virgin polyester chips with zero recycled material added.
Adopting an advanced 3D hollow cross-section and 3D crimp setting process, this fiber mimics the fluffy support structure of natural down, while eliminating common industry pain points of down filling such as fiber leakage, moisture absorption, mildew growth and skin sensitization, making it an ideal eco-friendly alternative for global home textile, apparel, toy and automotive interior producers.
We offer fully customizable functional modifications including flame retardant, antibacterial and water-repellent properties, alongside adjustable specifications to meet your diversified commercial production needs.
Core Pain Points Solved: Filling collapse, agglomeration, and loss of bulk after washing or long-term use, which lead to high product after-sales rates and reduced brand reputation for home textile producers.
Solution & Verifiable Evidence: Our 3D×64mm fiber features a three-dimensional spiral crimp structure with 18%-22% crimpness, delivering a rebound rate of ≥95%. The 64mm long fiber forms a stable three-dimensional support network between fibers, maintaining ≥85% bulk retention after 60 washes. It fully recovers its fluffy texture with a simple pat, eliminating deformation and caking issues even after prolonged use.
Core Pain Points Solved: Unqualified raw materials with impurities, odors, or harmful substances, which fail to pass international market access audits and cause shipment rejection for commercial clients.
Solution & Verifiable Evidence: Produced exclusively from brand-new virgin polyester chips, our fiber is free of recycled materials, fluorescent agents and impurities, with high whiteness and zero odor. It fully complies with OEKO-TEX® Standard 100, ISO 9001:2015 and REACH standards, with third-party test reports provided for each batch. We offer full document support to help you pass supplier audits of global brands and smoothly access high-end markets in Europe, North America and beyond.
Core Pain Points Solved: Inconsistent fiber quality between batches, insufficient production capacity, and delayed delivery, which disrupt your production schedule and peak season stocking plans.
Solution & Verifiable Evidence: As a fully integrated polyester fiber manufacturer with an annual production capacity of 50,000 tons, we implement a full-process quality management system with online sampling inspection every 2 hours. Our internal control standards for fiber tenacity, elongation and length deviation are 20% stricter than national standards, ensuring consistent quality across every batch. Our manufacturing site is just 120km from Shanghai Port, enabling container loading within 24 hours, maximizing shipping flexibility and avoiding demurrage and delivery delay risks for your bulk orders.
Core Pain Points Solved: Fiber tangling, static electricity and high breakage rate during opening and filling, which lead to low production efficiency, high material loss and high defective rate for manufacturers.
Solution & Verifiable Evidence: This fiber is treated with a special anti-static oil agent with an oil content of 0.2%-0.3%, ensuring smooth opening, minimal tangling and low fiber breakage during processing. It is compatible with most mainstream opening and filling equipment, with a breakage rate of ≤0.2% during production, effectively improving your production efficiency and reducing material loss. We support full customization of hollow pore count, fineness, length and functional properties to fit your unique production requirements.
