Shenghong Holding Group Co., Ltd. is an international high-tech industrial group integrating petrochemical refining, new energy, new materials, and advanced textiles. Ranked No. 161 on the 2025 Fortune Global 500 list, the company was founded in 1992 and headquartered in Suzhou, Jiangsu. Its subsidiary, Shenghong Chemical Fiber New Materials, is a global leader in differentiated fibers, widely recognized as the "Global Expert in Differentiated Fibers." Leveraging an advanced PTA and polyester industry chain, Shenghong possesses strong R&D and manufacturing capabilities in high-end PET polyester chips, with products widely used in textiles, packaging, and functional materials.
1. Core Competitive Advantages
- Integrated Industrial Chain: Shenghong has built a complete industrial chain from PTA → MEG → PET polyester chips → polyester filament, ensuring self-sufficiency in raw materials, controllable quality, and stable product consistency and supply.
- Green Technology Leadership: The first in the world to apply carbon capture technology in fiber production, launching the carbon-capturing PET fiber brand "Reocoer Ruikong," which captures 364 kg of CO₂ per ton of DTY fiber, reducing carbon emissions by 28.4%.
- Pioneer in Recycled Materials: Produces "Reborn Ruibang" recycled polyester fiber from recycled plastic bottles, supporting both mechanical and chemical recycling pathways. The product features traceable identification technology, meeting international brands’ sustainable supply chain requirements.
- World-Class Technology and Equipment: Polyester production units utilize DuPont (USA) patents and Chemtex design; spinning equipment is imported from Barmag (Germany) and TMT (Japan); key inspection instruments are fully imported, ensuring premium product quality.
2. Textile-Grade PET Polyester Chip Product Series
Shenghong’s PET polyester chips are renowned for their high purity and stability, primarily used in producing polyester filament (POY, FDY, DTY), and widely applied in high-end apparel, home textiles, and industrial textiles. Core products include:
1. Standard Polyester Chips (Textile-Grade PET Chips)
- Intrinsic Viscosity: 0.67–0.69 dl/g (suitable for melt direct-spinning filament)
- Main Applications: Polyester partially oriented yarn (POY), fully drawn yarn (FDY), draw-textured yarn (DTY)
- Product Advantages:
- High transparency, low color value (L≥83, B≤0), natural luster
- Low acetaldehyde content (≤1.0 mg/kg), reducing spinning odor
- Stable carboxyl end groups (≤35 mol/t), enhancing spinning stability
- Strict control of moisture and dust (moisture ≤0.3%, dust ≤50 mg/kg), ensuring continuous production
2. Full Dull Polyester Chips (Full Dull PET Chips)
- TiO₂ Content: ≥0.5%
- Main Applications: Cotton-like, linen-like fabrics, home textiles, high-end knits
- Product Advantages:
- Soft luster, closely resembling natural fibers
- Uniform dispersion, eliminating "cloudy spots"
- Excellent dye affinity, ensuring even dyeing
- Supports development of high-value differentiated products
3. Cationic Dyeable Polyester Chips (Cationic Dyeable PET Chips)
- Intrinsic Viscosity: 0.68±0.02 dl/g
- Main Applications: Cationic DTY, high-shrinkage fibers, blended fabrics
- Product Advantages:
- Can be dyed together with standard polyester in the same bath, achieving dual-color effects
- High colorfastness, vibrant and long-lasting colors
- Suitable for developing bicomponent elastic composite yarns such as "Wuhong," "H400," and "BEY"
4. Bio-based PTT Resin (Bio-based PTT Resin)
- Raw Material Source: Non-food-grade palm oil residue
- Main Applications: PTT fiber, elastic composite yarn, sportswear
- Product Advantages:
- Combines the softness of nylon with the stain resistance of polyester
- Excellent elasticity, ideal for high-stretch fabrics
- Can be co-spun with PET to produce eco-friendly elastic fibers such as T400 and T8
3. Technology and Certification Assurance
Shenghong’s PET chip production is fully traceable, certified under ISO9001, ISO14001, and OHSAS18001 management systems. Products meet international food contact material standards (FDA, EU) and support customized development of specialty chips with specific viscosity or additive formulations. The company hosts a National-recognized Enterprise Technology Center and a Postdoctoral Research Station, holding 172 authorized patents (including 41 invention patents), continuously driving industry technological advancement.
