Jiangyin Zhongjin Chemical Fiber Co., Ltd. (JZCF), a leading Chinese polyester fiber manufacturer with over 10 years of dedicated industry expertise, presents our premium 6D×64mm virgin 3D hollow conjugated polyester staple fiber. Engineered exclusively for high-support, high-resilience filling scenarios, this fiber is spun from 100% brand-new virgin polyester chips with zero recycled material addition. It is the ideal filling solution for home textile manufacturers, automotive interior suppliers, and industrial product producers, solving core pain points of easy collapse, insufficient support, and short service life common in standard filling materials.
Pain Point: Conventional filling fibers suffer permanent deformation and collapse under long-term heavy load, driving up after-sales costs and eroding brand reputation for commercial manufacturers.
Solution: Our 6D×64mm hollow conjugated polyester staple fiber adopts a high-denier 6D specification paired with 64mm cut length, forming a stable 3D interwoven fiber network. With 20%-25% high spiral crimp setting, it delivers a rebound rate of ≥98%.
Verifiable Evidence: Its fatigue resistance is 2-3 times that of ordinary fine-denier fibers, maintaining stable performance after tens of thousands of compression cycles, perfectly suited for sofa cushions, mattress cores, and car seat applications.
Pain Point: Recycled polyester fibers often carry impurities, odors, and harmful substances, failing international environmental certifications, and cause static entanglement during production, leading to high loss and defect rates.
Solution: 100% virgin polyester spinning ensures zero impurities and odor, with a specialized anti-static oil agent (oil content 0.2%-0.3%) for smooth opening and no knotting.
Verifiable Evidence: The fiber meets Oeko-Tex Standard 100 and REACH requirements, compatible with most mainstream opening and filling equipment, effectively reducing production loss and defect rates.
Pain Point: Traditional fillers cannot balance support performance with lightweight and thermal insulation, and are prone to moisture agglomeration in humid or outdoor environments.
Solution: 3D hollow cross-section (hollowness ≥25%) locks air for excellent heat insulation while remaining lightweight, with a moisture content ≤0.6% to prevent moisture absorption.
Verifiable Evidence: Chemically stable virgin polyester offers outstanding anti-aging and mildew resistance, ideal for outdoor furniture, camping gear, and automotive interior insulation.
