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, […]
Production Process for Low-Shrinkage Polyester Industrial Yarn Using Low-Viscosity Polyester
Polyethylene Terephthalate (PET) is a high-performance plastic known for its high strength, stiffness, impact resistance, and excellent dimensional and heat stability. It is ideal for making industrial yarn. PET is used in various products, such as: As production increases, PET‘s importance in the industry grows. 1. Problems with Traditional Processes Traditional processes use six pairs […]
Exploring the Production Process of Fine Denier Shaped ECDP FDY
In recent years, as fiber production technology has advanced and textile science has progressed, the development and use of high-value, specialized fibers have become a hot topic in the textile industry. Today, we will explore a special type of fiber—Fine Denier Shaped ECDP FDY. This fiber has many unique advantages and a wide range of […]
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 […]
