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 […]

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% […]
How to Make Polyester Monofilaments for Car Seat Belts

Car seat belts are crucial safety devices. Their performance depends heavily on the quality of the materials used. Let’s explore the innovative process for creating high-performance polyester monofilaments designed specifically for car seat belts. 1. What Makes Car Seat Belts Unique? Car seat belts serve both functional and decorative purposes, so their materials must meet […]
What is Sizing Dropping and How to Reduce It

What is Sizing Dropping? Sizing dropping (also called shedding or fiber drop) happens when the sizing agent or fibers fall off the yarn during the sizing process. This affects fabric quality, and textile mills often test for the amount of dropping to improve production. 1. Causes of Sizing Dropping 2. How to Reduce Sizing Dropping […]
Introduction to Polyester Hot Melt Yarn: Uses, Characteristics, and Raw Materials

1. What is Polyester Hot Melt Yarn? Polyester hot melt yarn is a special fiber material used for bonding in non-woven, knitted, and woven products. It combines with regular polyester or other fibers to create soft, strong, washable, and easy-to-manage materials. This yarn is eco-friendly, making it a valuable resource in modern textile production. 2. […]
