BCF Carpet Yarn Chip Selection Guide
How polyester chips affect carpet softness, bulk, and resilience Polyester chips are the core raw material for BCF (Bulked Continuous Filament) carpet yarn. From our years of working with spinning mills and carpet producers, we’ve seen that many carpet performance issues — like carpets feeling too hard, flattening easily, or not bouncing back — actually […]
How to Make Partially Biodegradable Short Fibers Using PBAT and PET
As the world pushes for greener products, fiber makers are looking for ways to make polyester fibers more eco-friendly. One way is to mix PBAT (a soft, biodegradable plastic) with PET (the standard polyester used in fibers). This approach can give you fibers that are strong, soft, and partly biodegradable. Here’s how it works and […]
Fluorine-Free Water-Repellent Fibers and Fabrics: Principles, Processing, Applications, and Practical Guide
Water-repellency is now a key feature for outdoor clothing, functional daily wear, tents, bags, and sports shoes. With stricter environmental rules, fluorine-free water-repellent (FFWR) technology is becoming the standard. Based on years of R&D and manufacturing experience, this article explains FFWR fibers from a manufacturer’s perspective. You’ll learn about how they work, how they are […]
High Viscosity, Low Shrinkage PET Chips: Enhancing Efficiency and Stability in Textile Factories!
In the production of technical textiles such as industrial yarns, seat belts, and curtain fabrics, have you encountered these issues?❌ Frequent yarn breakage?❌ Fluctuating spinning pressure?❌ High strength deviation and low product yield?❌ Severe batch-to-batch variation in customer acceptance?Don’t worry, HMLS Polyester Chips (High Modulus Low Shrinkage) are being increasingly selected by factories as the […]
Why Did Our Client’s Yarn Breakage Rate Drop from 4.5% to 1.3% ?
At HanLink Polyester, we focus on developing high-performance functional PET chips. In recent years, more and more customers ask us the same question: “Are you using ethylene antimony? Why is spinning so smooth?” It’s time to explain why. 1.Why Do We Use Ethylene Antimony? A. Unstable reaction rate, which caused long poly time and IV […]
Analysis of the Flame Retardant Performance of Low Carboxyl Copolyester in Monofilament
In the field of monofilament for automotive interiors, flame retardancy and long-term stability are core requirements. Our developed low-carboxyl-content flame-retardant copolyester chips exhibit significant advantages in enhancing flame retardant performance by optimizing the polymer structure and reducing side reaction risks. 1. Technical Description The low carboxyl content flame-retardant copolyester chips used in monofilament applications offer […]
Why More Manufacturers Are Choosing Low COOH Polyester Chips for Mother Yarn
As demand grows for higher quality, more stable, and environmentally friendly polyester yarns, low carboxyl end group (COOH) polyester chips are becoming the material of choice, especially in the production of semi-dull mother yarn. At HanLink Polyester, we’ve worked closely with fiber manufacturers to understand what really matters during spinning and downstream processing. Here’s why […]
Copper-Modified Polyester Fiber: A Powerful Antibacterial Solution for Textiles
The Need for Functional Textiles Consumers want more than just stylish and comfortable fabrics. They now look for textiles with extra features like antibacterial, odor-resistant, and mite-resistant qualities. This is especially important in medical, sportswear, and home fabrics. Traditional antibacterial treatments often wear off after washing and can contain harmful chemicals. Copper-modified polyester fiber solves […]
High-Viscosity, Low-Carboxyl Polyester Chips for Industrial Yarn: Benefits and Applications

The Importance of DEG Content-7% in Textile-grade PET Chips
Low-melting-point PET fibers are increasingly used in hot-melt layers and automotive nonwoven fabrics. These fibers need a low melting point, good bonding, and strong mechanical properties. Adding diethylene glycol (DEG) helps achieve this. The LMPET, keeping DEG at 7% lowers the melting point while maintaining fiber performance. This article explains why controlling DEG at 7% […]
