Chemical Recycled Polyester Staple Fiber
From Waste Polyester to High-Quality Fiber
Using glycolysis and advanced purification technology, we regenerate waste polyester into recycled polymer suitable for staple fiber production. This molecular-level recycling approach helps address the quality limitations associated with conventional mechanical recycling.
Product Overview
This premium post-consumer recycled polyester staple fiber is manufactured with a proprietary glycolysis depolymerization and re-polymerization process. Conventional mechanical recycling simply melts and re-extrudes waste polyester, which causes progressive quality degradation with each recycling cycle.
The chemical process breaks long polyester polymer chains into their basic monomer, BHET (bis(2-hydroxyethyl) terephthalate). After deep purification to remove dyes, oils and foreign contaminants, the high-purity monomers go through re-esterification and polycondensation with ethylene glycol to produce recycled polyester chips with uniform molecular weight distribution. Chemical Recycled PSF is then melt-spun from these chips through standard fiber production lines.
This monomer-level regeneration avoids the chain scission and property degradation inherent in physical recycling. Chemical Recycled PSF delivers tenacity, whiteness and dye uniformity that meet or exceed virgin polyester standards in every production batch. The process accepts a wide range of feedstock, from post-consumer garments and PET bottle flakes to industrial spinning waste, making it a future-proof solution for textile circularity.
Chemical Recycling Technology
The core technology behind Chemical Recycled PSF is ethylene glycol glycolysis -- the most industrially mature chemical recycling pathway for polyester, commercialized globally by DuPont, Teijin, and Far Eastern New Century. Different has independently optimized the process for textile-grade post consumer recycled polyester feedstock.
The process comprises four stages:
1) Pretreatment: Waste polyester textiles and bottle flakes are sorted, cleaned, and shredded. Chemical recycling tolerates dyed, mixed-color, and lightly blended feedstocks that mechanical processes cannot handle.
2) Glycolysis depolymerization: Under catalytic conditions at 180-250 degrees Celsius, PET polymer chains undergo transesterification with ethylene glycol, breaking into BHET monomer and minor oligomers -- achieving precise molecular-level deconstruction.
3) Purification: The depolymerized product undergoes distillation, crystallization, and multi-stage filtration to remove dyes and impurities, yielding monomer purity exceeding 99.5 percent, meeting virgin-grade feedstock specifications.
4) Re-polymerization and spinning: Purified BHET monomer is re-esterified and polycondensed into recycled polyester chips, then melt-spun using standard virgin fiber production lines. The resulting recycled psf exhibits bright whiteness, uniform denier, and stable mechanical properties virtually identical to virgin polyester staple fiber.
Core Advantages
Virgin-Equivalent Quality, Infinite Circularity
The monomer-level regeneration pathway of Chemical Recycled PSF guarantees that fiber quality does not degrade with repeated recycling. Unlike mechanically recycled polyester products (which experience 30-40 percent tenacity loss after 3-5 cycles), Different Chemical Recycled PSF theoretically supports unlimited closed-loop regeneration, consistently delivering virgin-grade strength, whiteness, and dyeability.
Broad Feedstock Compatibility
While mechanical recycling is largely limited to clear, high-purity PET bottle flakes, chemical recycling can process dyed textiles, mixed-color waste, and even lightly blended materials. This dramatically expands the feedstock pool for post consumer recycled polyester production and provides a scalable solution for the growing challenge of post-consumer textile waste.
Superior Processability
Chemically regenerated recycled polyester chips feature narrow molecular weight distribution and uniform melting point, ensuring low breakage rates during spinning and high first-quality yield. Downstream carding, yarn spinning, weaving, and dyeing processes require no parameter adjustments compared to virgin polyester.
Low-Carbon, Certified Sustainability
The full production chain is eligible for GRS (Global Recycled Standard), RCS (Recycled Claim Standard), and OEKO-TEX Standard 100 certification.
