Hengli PET Chips Fiber Grade
Hengli Group (Hengli Group) is a leading private petrochemical and new materials industrial group in China, headquartered in Suzhou, Jiangsu Province, founded in 1994. As the world's largest production base for functional fibers and a benchmark enterprise for integrated industrial chain development, Hengli has established a complete closed-loop industrial chain from "crude oil → refining → petrochemicals → polyester → civilian and industrial yarn → textile". The group owns multiple entities, including Hengli Petrochemical (stock code: 600346), and operates nine modern industrial parks in Suzhou, Dalian, Suqian, and Luzhou, with over 200,000 employees.
In 2024, Hengli Group ranked 81st on the Fortune Global 500 with a revenue of 871.5 billion yuan, and is the 3rd largest among China’s top 500 manufacturing enterprises. Its production capacities for PTA, polyester filament, and polyester film are all among the world’s highest.
1. Core Competitive Advantages
- Full Industrial Chain Integration: From crude oil refining to end textile products, ensuring self-sufficiency in raw materials, cost control, and product quality stability, breaking long-term foreign monopolies on high-end polyester materials.
- World’s Largest PTA Production Base: The Changxing Island industrial park in Dalian has an annual PTA capacity of 12 million tons, utilizing advanced technology from Invista (USA), making it one of the largest and most technologically advanced single-site PTA plants globally.
- Petrochemical Integration Benchmark Project: The 20-million-ton-per-year integrated refining project, invested nearly 80 billion yuan, is the first major private-sector refining project approved by the State Council, significantly reducing upstream raw material costs.
- Green and Intelligent Manufacturing: Multiple production bases have been recognized as national-level "Green Factories", with full-process digital management, improving production efficiency by over 30% and keeping product defect rates below 2%.
- Global Customer Collaboration: Maintains long-term supply relationships with international fast-fashion brands such as ZARA, H&M, and Uniqlo, while also supplying bottle-grade PET materials to Coca-Cola and Nongfu Spring.
2. Textile-Grade PET Chip Product Series
Hengli’s fiber-grade PET chips are the core raw material for polyester filament, widely used in spinning POY, FDY, DTY, and other polyester fibers, ultimately applied in apparel, home textiles, and industrial textiles. The products are renowned for their high purity, stability, and low impurities, meeting the stringent requirements of advanced melt direct-spinning processes.
1. Semi-Dull PET Chips
- Intrinsic Viscosity: 0.67–0.69 dl/g
- Main Applications: Polyester pre-oriented yarn (POY), fully drawn yarn (FDY), draw-textured yarn (DTY)
- Key Advantages:
- High fiber strength and uniformity, low yarn breakage rate during spinning
- Stable color values (L≥83, B≤1.0), natural and soft luster in finished products
- Low terminal carboxyl group content (≤35 mol/t), enhancing spinning process stability
- Strict moisture control (≤0.3%), ensuring safe continuous production
2. Super Bright PET Chips (e.g., DJ20678A)
- Representative Model: DJ20678A
- Intrinsic Viscosity: 0.68±0.02 dl/g
- Main Applications: High-end apparel fabrics, stage costumes, decorative textiles
- Key Advantages:
- High gloss and transparency, providing a brilliant visual effect to fabrics
- Narrow molecular weight distribution, smooth spinning process with minimal fuzz
- Suitable for high-speed spinning (3000–3600 m/min)
- Widely used in garments, curtains, and lightbox fabrics requiring high gloss
3. Full Dull PET Chips
- TiO₂ Content: ≥0.5%
- Main Applications: Cotton-like, linen-like fabrics, high-end knits, home textiles
- Key Advantages:
- Soft luster, closely resembling the visual texture of natural fibers
- Uniform titanium dioxide dispersion, avoiding "cloudy spot" defects
- Excellent dyeing performance, with rich and even coloration
- Ideal for developing high-value-added differentiated fibers
4. Industrial Yarn Grade PET Chips
- Main Applications: Tire cords, seat belts, conveyor belts, geotextiles, fishing nets
- Key Advantages:
- High strength, high modulus, impact resistance, and heat resistance
- High molecular weight and stable viscosity, meeting industrial yarn spinning requirements
- One out of every three garments worldwide uses polyester fiber derived from Hengli’s raw materials, with dominant market presence in industrial yarn as well
5. Functional PET Chips
- Product Types:
- Moisture-wicking fiber chips (for sportswear)
- Flame-retardant fiber chips (for firefighting gear, industrial protection)
- Antibacterial fiber chips (for medical textiles)
- Microfiber ultra-fine structure chips (for synthetic leather)
- Technical Highlights: Special fiber properties are achieved through chemical modification or physical compounding, resulting in gross margins over 20% higher than standard products.
3. Quality & Certification Assurance
Hengli’s polyester chip production is fully traceable, certified under ISO9001, ISO14001, and OHSAS18001 management systems. Products comply with international food contact material standards such as FDA and EU (applicable to bottle-grade PET), and custom formulations with specific viscosity or additives can be developed upon request.
The company has established a national "Enterprise Technology Center" and a Postdoctoral Research Station, collaborating with global leaders like Germany’s Brückner to develop advanced biaxially oriented polyester films. Product thickness variation is controlled within ±1 micron, widely used in high-end packaging and electronic components.
