Modified Polyester Fiber: The Next Generation of Polyester
As times change and living standards rise, people seek fabrics that are not only durable but also comfortable and functional. The new fabric, Modified polyester fiber, overcomes many shortcomings of regular polyester and marks the beginning of Polyester 2.0. Modified polyester fiber adds hydrophilic groups and soft segments to the original polymer. This makes it […]
Improving Polyester Geotextile Materials
Polyester filament geotextiles are made with high-strength, low-stretch industrial filaments. Key performance indicators are impact resistance and tensile strength. For optimal performance, these filaments need high tensile strength and resistance to deformation. The strength at 5% elongation measures their performance. 1. Problems with Traditional Polyester Filament Geotextiles Traditional polyester filament geotextiles have issues. High-strength, low-stretch filaments […]
High-performance Flame-retardant Polyester Chips Used in Industrial Monofilament
Industrial monofilament is a high-strength, coarse filament with a fineness of at least 550 dtex. Polyester (PET) industrial monofilament has excellent properties. It has high dry and wet strength, high modulus, low elongation, and good fatigue resistance. It is widely used in tire cord fabric, conveyor belts, tarpaulins, automotive seat belts, and advertising lightbox fabrics. […]
Development of Low Melting Point Polyester Chips by HanLink Polyester
Low melting point polyester is a modified polyester with a lower melting point. By adding modifying components during the regular PET polymerization process, we change its molecular structure. This reduces the polymer’s crystallization ability, lowering its melting point. Low melting point polyester can partly replace traditional adhesives. It is a green and eco-friendly product. It […]
The Application of Sodium Dimethyl 5-Sulfoisophthalate (SIPM) in Alkali-Soluble PET Chip
When it comes to cationic polyester chips, we focus on the dye uptake, which is influenced by the third monomer. The third monomer, SIPM, plays a key role in cationic polyester chips. SIPM not only enhances the dyeing properties of the polyester but also improves its moisture absorption and softness. Therefore, understanding the reaction rate […]
Factors Affecting Carboxyl End Groups in Textile-Grade Polyester Chips
An important influencing factor in textile-grade polyester chips is the carboxyl end group (-COOH). These groups form mainly during the esterification and polycondensation stages. Incomplete esterification reactions can leave carboxyl groups in the final product. Side reactions such as thermal degradation, thermo-oxidative degradation, and etherification in the polycondensation reaction will also produce carboxyl end groups. […]
Application of Polyester Fiber in Non-woven Fabrics
Polyester, scientifically known as polyethylene terephthalate (PET). It is a thermoplastic polymer widely utilized in various applications. It is a pivotal material in the production of non-woven fabrics through the spun-bond method. In China, the output accounts for about 6% of the total output of spun-bond non-woven fabrics. 1. Molecular Structure of PET PET molecules […]
Enhancing Packaging Efficiency with Durable Puncture-Resistant Aluminum Coating Films
In recent years, driven by economic growth, there has been an increasing demand for high-quality packaging for various goods. Irregularly shaped and sharp-edged items, such as those containing bones or fish bones, often encounter damage during the vacuum packaging process due to the stretching of aluminum layers in conventional aluminum-coated composite films. This necessitates the […]
Understanding the Differences Between DTY, FDY, and POY
When it comes to synthetic fibers like polyester, there are three main types to know about DTY, FDY, and POY. 1. DTY DTY for Draw Textured Yarn. It is made by intertwining single fibers through a process involving compressed air. It results in long strands with periodic network points. These fibers often have some elasticity […]
