Jiangyin Zhongjin Chemical Fiber Co., Ltd., a leading Chinese polyester fiber manufacturer, presents our high-performance 1.5D x 38mm super white regenerated polyester staple fiber. Made from premium polyester chips via melt spinning, drafting, setting and cutting processes, this fiber is tailor-made for global spinning mills, home textile manufacturers, non woven fabric producers and garment factories with strict requirements for fiber whiteness and purity. With a cotton-like soft hand feel, excellent process ability and batch-to-batch quality stability, it is an ideal cost-effective raw material for high-end spinning, nonwoven and textile production.
Pain Point: Textile producers face elevated production costs and environmental compliance risks from additional bleaching and brightening processes, while fiber yellowing and high impurity content drive up defective rates and rework costs.
Solution: Our super white regenerated polyester staple fiber adopts a low-impurity raw material formula to minimize yellowing tendency and impurity content from the source. With a whiteness of ≥90%, it can be directly used for high-whiteness textile production without extra brightening treatment.
Verifiable Evidence: The fiber has a defect content of ≤0.5mg/100g, is BPA-free, and can effectively reduce downstream production energy consumption, labor costs and chemical residue risks.
Pain Point: Poor fiber spinnability causes high end breakage rates and production loss, while non-standard fiber specifications require costly equipment adjustments for blending with natural fibers.
Solution: The 1.5D fine denier specification gives the fiber moderate specific surface area and excellent cohesion, while the 38mm standard cut length perfectly adapts to mainstream cotton spinning equipment, supporting both pure spinning and blending with cotton, viscose, modal and other fibers.
Verifiable Evidence: With a breaking strength of ≥4.5 cN/dtex, it ensures uniform yarn evenness, reduces end breakage rate and production loss, and maintains stable performance in various spinning processes.
Pain Point: Unstable fiber thermal shrinkage leads to uneven shrinkage during dyeing and setting, while poor wrinkle resistance shortens the service life of end textile products.
Solution: Through professional heat setting treatment, the fiber has excellent dimensional stability and low thermal shrinkage, while retaining the inherent wrinkle resistance, wear resistance and shape retention of polyester fiber.
Verifiable Evidence: It has a breaking elongation of 35%±5%, avoids uneven shrinkage in post-processing, and significantly improves the durability and service life of end textile products.
