    • The elasticity of Composite elastic yarn ST is extremely comfortable. Its unique chemical composition and structure endow it with just the right elastic performance,whether it’s minor stretching during daily wear or significant stretching in specific sports or activity scenarios, it can quickly and accurately return to its initial state and maintain a stable elastic modulus over the long term. This provides wearers with a consistent and comfortable wearing experience, effectively avoiding issues such as clothing slackening and deformation caused by poor elasticity, allowing the clothing to closely conform to the body curves as if it were a natural extension of the body.
    • From the perspective of elasticity principles, based on the synergistic effect of the two ester-based high polymers, PTT and PET. In multiple repeated tensile tests, it has exhibited highly linear elastic characteristics, further verifying the reliability and stability of its elasticity, enabling wearers to feel comfortable and natural elastic support during various activities.
  1. Good Weaving Processability:
    • During the textile processing, Composite elastic yarn ST demonstrates excellent weaving processability. Its fiber has a uniform fineness and a smooth surface, with good spinnability. It can easily adapt to various common weaving processes such as weaving and knitting. Whether it’s high-speed weaving or the knitting of complex tissue structures, it can proceed smoothly without easily encountering problems such as fiber breakage and entanglement. This greatly improves the textile production efficiency and helps ensure the quality stability of the finished fabric, providing convenient and efficient production conditions for textile enterprises.
    • Its good weaving processability benefits from its reasonable polymer ratio and advanced composite spinning process, which makes the internal structure of the fiber regular and enables all parts to work in synergy, thus showing excellent adaptability in the weaving process and being able to meet the requirements of different textile products for process and quality.
  1. Good Resilience:
    • The resilience of Composite elastic yarn ST is outstanding. After undergoing tensile deformation, The Composite elastic yarn ST can quickly return to its original shape with almost complete recovery. This is due to the unique performance combination of the two high polymers, PTT and PET, and the special microstructure formed during the composite spinning process. In multiple stretch-recovery cycle tests, the resilience remains at a high level, ensuring that the textiles made from it can maintain good appearance and performance during long-term use, even when frequently subjected to external forces, without wrinkling or deformation caused by insufficient resilience.
    • This excellent resilience also enables it to respond accurately and efficiently to external forces in different directions and magnitudes, providing reliable performance guarantees for various textile products with high elasticity requirements. It performs particularly well in clothing categories that require frequent stretching, such as sportswear and elastic outerwear.

3.Product Specifications

Composite elastic yarn ST has a variety of specifications to meet the diverse needs of different customers and application scenarios. The specific specifications are as follows:
  • 50D/24F: The fibers of this specification are relatively fine, characterized by lightness and softness, and are suitable for making light and close-fitting textiles, such as women’s short socks and lightweight casual wear. Based on ensuring a certain level of elasticity and strength, it can bring a delicate and comfortable touch to wearers.
  • 75D/36F: The fiber fineness is moderate, taking into account multiple aspects of performance such as elasticity, strength, and wear resistance. It is commonly used in the production of regular-thickness sportswear and elastic outerwear. While meeting the requirements for clothing stretchability during sports, it can also ensure the durability of the product and withstand the friction and pulling during daily activities.
  • 100D/48F: The fibers of this specification have an advantage in thickness, possessing higher strength and elasticity. They are suitable for making some clothing that requires both elasticity and stiffness, such as women’s pantyhose and certain styles of casual wear. They can show good shape and a comfortable wearing experience when worn.
  • 150D/68F: The fibers are relatively thick with further enhanced strength. They are often used in the production of elastic denim series products that require strong support and durability. While maintaining the original style of denim, they endow it with excellent elasticity and resilience, making denim clothing more comfortable and easy to move around in.
  • 300D/96F: This belongs to a relatively thick fiber specification, with extremely high strength and good elasticity. It can be applied to some industrial or special functional textile products with extremely high durability requirements, and can also meet the needs of some outdoor functional clothing for resisting harsh environments and frequent friction.
