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% […]

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. […]
Common Problems in Textile Sizing: A Simple Guide
The quality of textiles relies on both raw material selection and processes like spinning and sizing. One critical issue is yarn hairiness, which impacts weaving efficiency and the appearance of fabrics. Understanding what causes yarn hairiness and how to address it is essential for improving textile quality and lowering production costs. This article will explore […]
Study on the Performance of High-Strength Flame-Retardant Polyester Industrial Yarns Under High-Temperature Pre-Tension
Polyester industrial yarns are popular because they are strong and durable. They are used in things like car curtain lines, conveyor belts, and safety belts. As safety concerns rise, flame-retardant polyester industrial yarns are getting more attention. While flame retardants improve fire resistance, they can also change the yarn’s structure and performance. So, it’s important […]
Introduction to Bicomponent Yarn
1. What is Bico Yarn? Bi-component yarns are continuous filaments made by extruding two different materials from the same spinneret using bi-component technology. These yarns have advantages over single-component yarns because they can be tailored for specific functions. Fiber attributes include anti-static, antimicrobial, super hydrophilic, super hydrophobic, stain resistance, low melt, and heat resistance. These […]
Factors Influencing Polyester Monofilament Yarn
Polyester monofilament yarn is used in many industries, and its quality affects the final product’s performance and lifespan. To produce high-quality mono-filament yarn, manufacturers follow advanced processes to turn raw chips into top-notch yarn. This article explains the process and the relationship between various indices of chips. 1. Solid-State Polymerization To make high-quality mono-filament yarn, […]
Sea-Island Composite Fiber: A New Breakthrough in Textile Materials
Sea-island composite fibers have better properties than natural fibers. They are becoming more popular in the textile industry. 1. Common Problems with Sea-Island Composite Fibers Most sea-island composite fibers use alkaline-soluble polyester (COPET) as the sea component. These fibers need strong alkaline conditions at high temperatures (≥95°C, pH value ≥13) to break down COPET. However, […]
