ShengHong Recycled PET Chips Fiber Grade
Shenghong Holding Group Co., Ltd. is a globally leading integrated industrial group specializing in high-end textiles and new energy materials. Ranked No. 161 on the 2025 Fortune Global 500 list, the company has established the world’s largest production base for recycled fiber, with an annual capacity of 600,000 tons, earning the title of “Global Expert in Differentiated Fibers”.
1. Core Competitive Advantages
- Full Industry Chain Integration: Starting from dyeing in 1992, Shenghong has gradually extended upstream to form a closed-loop industrial chain of “Refining—New Materials—High-End Textiles”. Its subsidiary, Shenghong Chemical Fiber New Materials, is a global leader in recycled polyester and carbon-capture fibers, achieving full control from crude oil to green fiber production.
- World’s Largest Recycled Fiber Capacity: Shenghong has built a 600,000 tons/year recycled fiber production capacity, making it the largest recycled polyester fiber base globally. It recycles nearly 36 billion waste plastic bottles annually, equivalent to reducing 1 million tons of CO₂ emissions per year.
- World’s First Melt Direct-Spinning Line from Flake to Yarn: Shenghong independently developed the world’s first melt direct-spinning system from recycled flakes to filament, overcoming key technical challenges such as melt viscosity homogenization and large-scale polymerization, enabling long-cycle stable production of recycled fibers with a 90% differentiation rate.
- National-Level Innovation Platforms: In 2019, Shenghong led the establishment of China’s first National Advanced Functional Fiber Innovation Center initiated by a private enterprise, supported by national enterprise technology centers and advanced materials research institutes, continuously breaking through core technological bottlenecks.
- Globally Leading Green Technologies: Shenghong has built a full-process green system of “source carbon reduction, process carbon reduction, end-use carbon utilization”, developing two flagship green products: CO₂-based polyester fiber (reocoer) and recycled polyester fiber (Reborn), both highly recognized by international brands.
2. Recycled PET Polyester Chip Product Series
Shenghong transforms post-consumer PET bottles and textile waste into high-quality recycled polyester chips using physical and chemical recycling technologies. The products feature traceability, low carbon footprint, and high differentiation, widely used in apparel, home textiles, and technical textiles.

2. reocoer (RuiKong) Carbon-Capture Fiber
- Raw Material: CO₂ emissions captured from factory exhaust, converted into green ethylene glycol, then polymerized with PTA
- Core Technology: World’s first low-carbon circular industrial chain of “CO₂ capture and utilization—green ethylene glycol—functional polyester fiber”, holding 13 core patents
- Key Advantages:
- 364 kg of CO₂ captured per ton of carbon-capture DTY produced
- 28.4% lower carbon emissions compared to virgin fiber
- Fully traceable, highly recognized by global brand partners
3. PTT Bio-Based Green Yarn
- Raw Material: Derived from palm oil residue, non-food grade, environmentally sustainable
- Product Features:
- Combines the softness of nylon, stain resistance of polyester, and excellent resilience
- Can be co-polymerized with PET to produce bicomponent elastic fibers (e.g., H400, BEY, HEY)
- Applications: High-value products such as sportswear, underwear, and outdoor gear
3. Quality & Certification Assurance
Shenghong adheres to the principle of “high quality in production, zero defects at shipment”. Its products are certified under international standards including ISO9001, ISO14001, and GRS (Global Recycled Standard), ensuring full traceability and safety control from raw material recycling to final product delivery. Its recycled products have entered the supply chains of global brands such as Nike, Adidas, and Uniqlo, establishing Shenghong as a benchmark for green transformation in the global textile industry.
