What are the advantages of polyester hot melt yarn over traditional materials?
In the textile industry, polyester hot melt yarn, as an emerging functional fiber, has gradually shown many advantages with its unique properties and wide application fields. Compared with traditional materials, it has significant competitiveness in many aspects.

Low melting point and excellent bonding performance
Polyester hot melt yarn has a low melting point, and the common melting point range is between 110℃ and 180℃. This feature enables it to melt quickly at a lower temperature when blended or composited with other fibers, thereby bonding different fibers together. For example, when producing non-woven fabrics, knitting or weaving into thermally bonded fiber products, polyester hot melt yarn can effectively bond various fibers firmly together. This excellent bonding performance not only improves the overall strength and stability of the product, but also avoids the environmental pollution problems that may be caused by the use of traditional chemical adhesives

High strength and good durability
The strength of polyester hot melt yarn is very high, with the strength of short fibers ranging from 2.6 to 5.7 cN/dtex, and the strength of high-strength fibers as high as 5.6 to 8.0 cN/dtex. Due to its low hygroscopicity, the wet strength is basically the same as the dry strength, and the impact resistance is also excellent, 4 times higher than nylon and 20 times higher than viscose fiber. This high strength and good impact resistance enable polyester hot melt yarn to provide reliable protection when making various products that need to withstand large tension and impact. For example, when making outdoor sports shoe uppers, car linings and other products, polyester hot melt yarn can ensure the durability and service life of the product

Excellent elasticity and good dimensional stability
The elasticity of polyester hot melt yarn is close to that of wool, and it can almost be fully recovered when stretched by 5% to 6%. This excellent elasticity enables polyester hot melt yarn to provide good comfort and fit when making clothing, home textiles and other products. At the same time, the wrinkle resistance of polyester hot melt yarn also exceeds that of other fibers, that is, the fabric is not easy to wrinkle and has very good dimensional stability. This means that in products using polyester hot melt yarn, such as curtains, sofa fabrics, etc., they can maintain long-term beauty and shape, are not prone to deformation or wrinkles, and enhance the overall texture and grade of the product

Excellent wear resistance and long service life
The wear resistance of polyester hot melt yarn is second only to nylon, and is better than other natural fibers and synthetic fibers. When making textiles that require frequent friction or long-term use, such as sports shoe uppers, sofa fabrics, etc., polyester hot melt yarn can effectively resist wear and extend the service life of the product. This excellent wear resistance makes polyester hot melt yarn more advantageous than traditional materials in some high-intensity use scenarios

Environmentally friendly and pollution-free, in line with sustainable development requirements
Polyester hot melt yarn is an environmentally friendly material that can effectively reduce pollution to the environment. During the production process, it does not require the use of chemical adhesives such as glue, avoiding the pollution of volatiles and powder layers. At the same time, polyester hot melt yarn will not cause secondary pollution to the environment after use and disposal. This is in line with the current trend of sustainable development in the textile industry, meets consumers’ demand for environmentally friendly products, and helps companies establish a good social image and market competitiveness

Easy to process and improve production efficiency
Polyester hot melt yarn has good processing performance and is easy to mix with other fibers for processing. During the production process, it can be bonded by dry heat or wet heat, with a simple process flow, saving production time and cost. For example, when making 3D flying woven uppers, polyester hot melt yarn can quickly bond with other fibers to form a stable structure, improving production efficiency. In addition, polyester hot melt yarn has good thermoplasticity and can be reshaped after heating, providing more possibilities for product design and innovation

Wide application fields and broad market prospects
Polyester hot melt yarn has a wide range of applications, covering outdoor sports uppers, casual uppers, sofa fabrics, curtains and window screens, carbon fiber cloth shaping, chenille yarn, Bondi line, high-end suit lining, lace and glove lock edge yarn and other fields. Compared with traditional materials, polyester hot melt yarn can meet the specific needs of more industries and products, and has greater market potential and development space. With the continuous advancement of technology and the continuous changes in consumer demand, the application field of polyester hot melt yarn will be further expanded, and the market prospects are very broad.

In summary, polyester hot melt yarn has significant advantages over traditional materials in terms of low melting point, excellent bonding performance, high strength, excellent elasticity, excellent wear resistance, environmental protection and pollution-free, and easy processing. These advantages have made polyester hot melt yarn more and more widely used in the textile industry, and with the continuous growth of market demand, its market position and influence will be further enhanced.
