Application of polyester hot melt yarn in clothing

Application of polyester hot melt yarn in clothing
In the field of modern clothing manufacturing, polyester hot melt yarn, as a functional fiber, is gradually playing an important role. This article will explore in depth the various applications of polyester hot melt yarn in clothing manufacturing, including its unique advantages in improving clothing quality, optimizing production processes and reducing costs.

1. Basic characteristics of polyester hot melt yarn
Polyester hot melt yarn, also known as low melting point fiber, is a functional fiber made by modified polyester. Its main characteristics include:
Low melting point: The melting point of polyester hot melt yarn is usually between 85℃ and 180℃, and it can melt at a lower temperature, which is suitable for a variety of thermal processing processes.
High strength: The strength of short fibers is 2.6~5.7cN/dtex, and that of high-strength fibers is 5.6~8.0cN/dtex. The wet strength is basically the same as the dry strength.
Good elasticity: The elasticity is close to that of wool, and it can be almost completely recovered when it is elongated by 5%~6%, with good wrinkle resistance and dimensional stability.
Good heat resistance: Polyester fiber has excellent heat resistance and thermal insulation among synthetic fibers. It has thermoplasticity and can be used to make clothing that requires long-lasting pleats, such as pleated skirts.
Good wear resistance: The wear resistance is second only to nylon, and is better than other natural and synthetic fibers.

2. Application of polyester hot melt yarn in clothing
(I) Thermal bonding
One of the main applications of polyester hot melt yarn is as a thermal bonding fiber to replace traditional chemical adhesives. In clothing manufacturing, hot melt yarn can be mixed with other fibers to weave fabrics, and then pressure is applied under dry heat or wet heat. When the temperature is higher than the melting point of the hot melt yarn, the hot melt yarn gradually melts and bonds other fibers together. This method is not only environmentally friendly and non-toxic, but also saves process flow and reduces production costs.
(II) Improving the stiffness and wrinkle resistance of fabrics
In spring and summer light fabrics, the application of polyester hot melt yarn can significantly improve the stiffness and wrinkle resistance of fabrics. By using the polyester hot melt yarn with a skin-core structure as the core yarn and covering it with cotton fiber roving, after spinning process design and high-temperature shaping treatment, the polyester hot melt yarn undergoes hot melt self-bonding, changing the yarn structure in the fabric, thereby improving the stiffness and wrinkle resistance of the fabric. This method is particularly suitable for making thin summer clothing, such as shirts, dresses, etc.
(III) Seamless seam
In the detail processing of clothing, polyester hot melt yarn can be used for seamless seam. Through the thermal bonding effect of hot melt yarn, the edge of the clothing can be fixed and sealed without using traditional stitching, making the appearance of the clothing more neat and beautiful, while reducing the discomfort that may be caused by traditional stitching.
(IV) Bonding line weaving
In the weaving of bonded yarn, polyester hot melt yarn is used as a thermal bonding fiber to enhance the strength and durability of the ribbon. Bonded yarn is widely used in the collar, cuffs, trouser legs and other parts of clothing. The use of polyester hot melt yarn can improve the wear resistance and tensile resistance of these parts.
(V) Chenille yarn and high-end lining
Polyester hot melt yarn is also widely used in the production of chenille yarn and high-end lining. In chenille yarn, hot melt yarn can enhance the structural stability of yarn and improve the strength and wear resistance of yarn. In high-end lining, the application of polyester hot melt yarn can enhance the stiffness and wrinkle resistance of lining, making it more durable and easy to care for.

III. Technical advantages of polyester hot melt yarn
(I) Environmental protection and pollution-free
Compared with traditional chemical adhesives, polyester hot melt yarn does not produce volatile organic compounds (VOC) and dust pollution during use, which meets modern environmental protection requirements. This not only helps to protect the environment, but also improves safety during the production process.
(II) Process simplification
The use of polyester hot melt yarn can simplify the bonding process in clothing manufacturing and reduce the use of traditional adhesives, thereby reducing production costs and time. For example, in seamless lock and thermal bonding applications, no additional bonding steps are required, which improves production efficiency.
(III) Improve product quality
The application of polyester hot melt yarn not only improves the functionality of clothing, but also improves the appearance and feel of clothing. Through the thermal bonding effect of hot melt wire, a more delicate and uniform bonding effect can be achieved, making the clothing smoother and crisper, and improving the overall quality of the product.
4. Market prospects of polyester hot melt wire
As consumers’ requirements for clothing quality and environmental performance continue to increase, polyester hot melt wire has broad application prospects in clothing manufacturing. Especially in the fields of high-end clothing, sportswear and functional clothing, the application of polyester hot melt wire will be more extensive. In addition, with the continuous advancement of technology, the performance of polyester hot melt wire will be further optimized, bringing more innovative possibilities to the clothing manufacturing industry.

5. Innovative applications and future prospects
(I) Smart clothing field
In the field of smart clothing, polyester hot melt wire can be used to fix electronic components and sensors to ensure their stability and comfort in clothing. Through the bonding effect of hot melt wire, electronic components can be firmly embedded in clothing fabrics to achieve a perfect combination of functionality and comfort of smart clothing.
(II) Sustainable fashion
With the rise of sustainable fashion, the recyclability and low environmental impact of polyester hot melt wire make it an ideal choice. It can not only reduce chemical pollution in the clothing manufacturing process, but also reduce the impact on the environment throughout the life cycle of clothing, which is in line with modern consumers’ pursuit of environmentally friendly fashion.
(III) Personalized customization
In personalized customized clothing, polyester hot melt yarn can be used to quickly customize and modify clothing sizes. Through the thermal bonding characteristics of hot melt yarn, clothing can be adjusted in a short time to meet the personalized needs of consumers and improve production efficiency and customer satisfaction.

VI. Conclusion
As a functional fiber, polyester hot melt yarn has many application advantages in clothing manufacturing. Through thermal bonding, it can not only improve the quality and functionality of clothing, but also simplify the production process and reduce production costs, which meets the environmental protection and high efficiency requirements of modern clothing manufacturing. With the continuous development of technology and the increase in market demand, the application of polyester hot melt yarn in clothing manufacturing will continue to expand, bringing more innovation and development opportunities to the clothing industry.
