Jiangyin Zhongjin Chemical Fiber Co., Ltd. (JZCF), a leading Chinese polyester fiber manufacturer, presents our premium non-fluorescent polyester staple fiber (1.5D×51mm). Engineered exclusively for textile mills, nonwoven fabric producers, home textile brands, and industrial textile suppliers, this fiber is tailored for applications with strict requirements for fluorescence-free safety, high whiteness, and exceptional spinnability. Made from 100% virgin polyester (PET) chips via advanced spinning technology, it contains zero fluorescent whitening agents, serving as an ideal raw material for mid-to-high count yarns, high-end apparel, medical textiles, and hygiene products.
Pain Point: Producers face frequent order rejection, export barriers, and compliance risks due to fluorescent substance non-compliance, especially for infant apparel, medical materials, and international orders with rigid safety standards.
Solution: Our fluorescence-free PET staple fiber adopts a dedicated formula and clean production process, with zero fluorescent whitening agents added across the entire production chain.
Verifiable Evidence: The fiber passes strict UV/red light inspection with no fluorescent reaction, complies with national and international standards, and is supported by third-party authoritative test reports, with full support for on-site factory audits.
Pain Point: Traditional 38mm polyester staple fiber causes poor fiber cohesion, uneven yarn evenness, high breakage rates, and low efficiency in mid-to-high count yarn production.
Solution: Our 1.5D×51mm polyester staple fiber features an optimized 51mm length for enhanced cohesion, fully compatible with ring spinning, compact spinning, and vortex spinning processes.
Verifiable Evidence: This specification significantly reduces spinning breakage rates, improves production efficiency, and enables stable manufacturing of premium mid-to-high count pure polyester and polyester-cotton blended yarns.
Pain Point: Low-grade polyester fiber leads to fabric pilling, yarn breakage, uneven dyeing, and poor color fastness during finishing processes.
Solution: Our fiber delivers high breaking strength, moderate elongation, and uniform fiber structure for excellent wear resistance, wrinkle resistance, and dyeing performance.
Verifiable Evidence: With a breaking strength of ≥4.5 cN/dtex, outstanding color fastness, and strong adaptability to setting and pre-shrinking processes, it minimizes defects and boosts final product qualification rates.
