Unique advantages of polyester hot melt yarn in clothing manufacturing
In the field of modern clothing manufacturing, polyester hot melt yarn is gradually emerging and becoming a highly anticipated material. It not only performs well in physical properties, but also has many unique advantages in bonding performance, product performance, environmental protection and economy, bringing new possibilities to clothing manufacturing.
I. Physical performance advantages
1. High strength
Polyester hot melt yarn has extremely high strength, the strength of short fibers can reach 2.6~5.7cN/dtex, and the strength of high-strength fibers is 5.6~8.0cN/dtex. The wet strength is basically the same as the dry strength, and the impact resistance is 4 times higher than nylon and 20 times higher than viscose fiber. This high-strength characteristic enables polyester hot melt yarn to withstand greater tension and pressure in clothing manufacturing, ensuring the durability and stability of clothing. Even after frequent wearing and washing, it is not easy to break or deform, extending the service life of clothing.
2. Good elasticity
The elasticity of polyester hot melt yarn is close to that of wool, and it can almost fully recover when stretched by 5% to 6%. Its elastic modulus is 22 to 141 cN/dtex, which is 2 to 3 times higher than nylon. This means that the clothing can maintain a good shape and fit during wearing, and is not prone to wrinkles or loosening. For example, when making sportswear, the high elasticity of polyester hot melt yarn can meet the stretching needs of the human body during exercise, and quickly recover to its original shape after exercise, providing a comfortable wearing experience.
3. Good wear resistance
The wear resistance of polyester hot melt yarn is second only to nylon, and is better than other natural and synthetic fibers. This allows clothing to resist friction and wear and maintain a good appearance and quality during daily wear and use. For example, when making jeans, work clothes and other clothing that require frequent friction, adding polyester hot melt yarn can significantly improve the wear resistance of clothing and reduce the frequency of patches and replacements.
4. Good heat resistance
Polyester hot melt yarn is a thermoplastic fiber made by melt spinning. It has a high melting point, small specific heat capacity and thermal conductivity, so it has good heat resistance and thermal insulation. In the process of clothing manufacturing, it can withstand high temperature treatment, such as ironing, dyeing and other processes, without deformation or damage. At the same time, in daily wear, it can also resist the high temperature of the external environment and maintain the performance and shape of clothing.
5. Good thermoplasticity
Polyester hot melt yarn has good thermoplasticity, which can be softened and melted by heating, and then re-solidified after cooling. This feature makes polyester hot melt yarn easy to process and shape in clothing manufacturing. For example, when making pleated skirts, its thermoplasticity can easily form long-lasting pleats, providing more creative space for clothing design and production.
2. Advantages of bonding performance
1. Excellent thermal bonding performance
Polyester hot melt yarn melts and flows at high temperatures, and re-solidifies into a solid state after cooling, so it has excellent thermal bonding performance. In clothing manufacturing, it can be used as an adhesive to bond different materials or fibers together to form a strong connection. For example, when making clothing linings, polyester hot melt yarn can tightly bond the lining to the outer fabric to prevent the lining from shifting or falling off, and improve the overall quality and wearing comfort of the clothing.
2. No chemical adhesive required
Compared with traditional bonding methods, the thermal bonding performance of polyester hot melt yarn does not require the use of chemical adhesives. This not only avoids the environmental pollution and harm to human health that may be caused by chemical adhesives, but also makes clothing more environmentally friendly and healthy. For example, when making children’s clothing, using polyester hot melt yarn for bonding can ensure the safety and non-toxicity of clothing, making parents more at ease.
3. High and long-lasting bonding strength
Polyester hot melt yarn has high thermal bonding strength, can form a strong bonding effect, and will not easily fall off or loosen during long-term use. This allows the clothing to maintain good integrity and stability during wearing, and will not affect the appearance and function of the clothing due to the failure of the bonding part. For example, when making high-end suits, the high bonding strength of polyester hot melt yarn can ensure that the lining of the suit fits tightly with the outer fabric, maintain the stiffness and shape of the suit, and extend the service life of the suit.
III. Product performance advantages
1. Good dimensional stability
Polyester hot melt yarn can provide good dimensional stability in clothing manufacturing. During processing and wearing, the size and shape of the clothing can remain relatively stable, and it is not easy to shrink, deform, and other problems. For example, when making shirts, the application of polyester hot melt yarn can ensure that the shirts still maintain their original size and version after washing and wearing, and will not shrink or deform, which improves the quality of clothing and consumer satisfaction.
2. Easy to care
Clothing made of polyester hot melt yarn is easy to care for. It does not require special maintenance and care, and only regular washing and ironing are required to keep it in good condition. For example, when making hotel uniforms, the easy-to-care characteristics of polyester hot melt yarn can reduce the time and energy of hotel staff in uniform maintenance and improve work efficiency.
3. Good dyeing performance
Polyester hot melt yarn has good dyeing performance and can be well combined with a variety of dyes to achieve rich color performance. In clothing manufacturing, various colors can be dyed according to design requirements to meet the aesthetic needs of different consumers. For example, when making fashionable women’s clothing, the dyeing performance of polyester hot melt yarn can achieve rapid switching of various popular colors, providing more creative space for clothing designers.
IV. Environmental protection and economic advantages
1. No pollution
Polyester hot melt yarn is an environmentally friendly material. There is no pollutant emission during the production process and no pollution to the environment. The use of polyester hot melt yarn in clothing manufacturing meets the requirements of modern society for environmental protection, helps enterprises establish a good environmental protection image, and wins the recognition and trust of consumers.
2. Recyclable
Polyester hot melt yarn has the characteristics of recyclability. After the clothing is discarded, the polyester hot melt yarn can be recycled and reprocessed to reduce resource waste and environmental pollution. This not only conforms to the concept of sustainable development, but also reduces production costs for enterprises.
3. Cost saving
The use of polyester hot melt yarn can save some process and material costs in the clothing manufacturing process. For example, no chemical adhesive is needed in the bonding process, which reduces the purchase cost of chemical adhesives; at the same time, its high strength and wear resistance also reduce the cost of repairing and replacing clothing during use, and improve the economic benefits of the enterprise.
In summary, polyester hot melt yarn has many unique advantages in clothing manufacturing. It not only performs well in physical properties, bonding properties and product performance, but also meets environmental protection and economic requirements. With the continuous advancement of science and technology and the improvement of consumers’ requirements for clothing quality, the application prospects of polyester hot melt yarn in the field of clothing manufacturing will become more and more broad.
