Product Overview
Jiangyin Zhongjin Chemical Fiber Co., Ltd. (JZCF), a leading Chinese polyester fiber manufacturer since 2015, presents our premium non-fluorescent polyester staple fiber 1.5D×38mm. Crafted from 100% virgin polyester (PET) raw materials, this specialty fiber is engineered to meet the strictest quality requirements of industrial manufacturers, textile producers, nonwoven converters and high-end home textile brands worldwide. With consistent high whiteness, zero fluorescent residue and stable physical performance, it is the ideal raw material for applications demanding safety, purity and reliable processability.
Core Features & Solution Value
Fluorescent-Free Compliance for Zero Quality Risks
Pain Point: Export-oriented manufacturers and commercial buyers face costly product returns, order rejections and reputational damage from fluorescent agent non-compliance in medical, infant apparel and high-end textile products.
Solution: Our non-fluorescent polyester staple fiber adopts a fluorescent-free brightening formula and precision process control, eliminating fluorescent agent residue entirely.
Verifiable Evidence: Compliant with GB/T 17685 standard, verified via professional UV/red light inspection with zero fluorescent abnormality, fully adapting to the strictest global quality inspection protocols.
Superior Processability & Production Efficiency
Pain Point: Spinning and nonwoven production lines suffer from high breakage rates, uneven yarn evenness and low yield, driving up manufacturing costs.
Solution: This 1.5D×38mm polyester staple fiber features excellent fiber uniformity, outstanding cohesion and stable mechanical properties, compatible with ring spinning, rotor spinning and mainstream nonwoven processes.
Verifiable Evidence: With a breaking strength ≥4.5 cN/dtex and defect content ≤1.0mg/100g, it significantly reduces end breakage, improves yarn evenness and boosts production yield for manufacturers.
Stable Whiteness & Premium Dyeing Performance
Pain Point: White/light-colored fabrics face yellowing, uneven whiteness and high dyeing color difference, requiring extra chemical brighteners and increasing production costs.
Solution: Our high-purity virgin PET polyester staple fiber delivers consistent high whiteness, a spot-free clean appearance and uniform fiber structure for excellent dye uptake.
Verifiable Evidence: Uniform luster without yellowing, high color fastness and minimal batch-to-batch color difference, reducing chemical auxiliary usage and aligning with green production trends.
