Introduction
In the textile industry, functional fibers are increasingly used, and polyester hot melt yarn, as a new type of functional fiber, is gradually becoming the darling of the market. Compared with traditional materials such as polypropylene and nylon, polyester hot melt yarn has shown significant advantages with its unique physical and chemical properties. This article will analyze the characteristics of polyester hot melt yarn and its application prospects in the international market from multiple perspectives.
1. Basic characteristics of polyester hot melt yarn
Polyester hot melt yarn is a fiber made by spinning low-melting-point polyester chips, and has the following basic characteristics:
Low melting point: The melting point of polyester hot melt yarn is usually between 110℃ and 140℃, which is much lower than that of conventional polyester fibers.
High thermal bonding strength: At high temperatures, polyester hot melt yarn can quickly melt and bond with other fibers to form a stable bond.
Stable physical and chemical properties: Polyester hot melt yarn has good strength and elasticity at room temperature, and has strong heat resistance and chemical corrosion resistance.
Environmental protection: Polyester hot melt yarn is an environmentally friendly material, and the waste generated during the production process can be recycled and reused.
2. Advantages of polyester hot melt yarn
1. Strength and wear resistance
The short fiber strength of polyester hot melt yarn is 2.6~5.7cN/dtex, and the high-strength fiber is 5.6~8.0cN/dtex, which is nearly 1 times higher than cotton and 3 times higher than wool.
Its wear resistance is second only to nylon, and is far superior to other natural and synthetic fibers.
2. Elasticity and dimensional stability
The elasticity of polyester hot melt yarn is close to that of wool, and it can almost be fully recovered after elongation of 5%~6%, with good wrinkle resistance and dimensional stability.
This makes it perform well in the field of clothing and home textiles, and can maintain the crispness and durability of the fabric.
3. Heat resistance and thermoplasticity
The heat resistance and thermal insulation of polyester hot melt yarn are excellent among synthetic fibers, with a high melting point and low specific heat capacity and thermal conductivity.
Good thermoplasticity, can be used to make products such as pleated skirts that require long-lasting pleats.
4. Environmental protection and sustainability
The waste generated during the production process of polyester hot melt yarn can be recycled and reused, effectively reducing the impact on the environment.
Compared with traditional chemical adhesives such as glue, polyester hot melt yarn avoids the pollution of volatiles and powder layers, and is more environmentally friendly.
5. Processing performance
Polyester hot melt yarn is easy to mix with other fibers, has stable processing performance, and is suitable for knitting, warp knitting, twisting and other processes.
Its thermal bonding performance saves the use of adhesives such as glue during the production process, reducing production costs.
3. Application fields of polyester hot melt yarn
Shoe material manufacturing: widely used in 3D shoe uppers, shoe material fabrics, etc., providing bonding, shaping and reinforcement functions.
Home textiles and curtains: used for curtains, window screens, sofa fabrics, etc., to improve the stiffness and washability of the product.
Automotive interior: used for automotive linings, seat fabrics, etc., to provide wear resistance and puncture resistance.
Garment manufacturing: In the fields of seamless underwear, glove lock edge yarn, etc., it provides bonding, shaping and anti-fragmentation functions.
Industrial use: used for webbing, parachute ropes, cable wires, etc., providing high strength and wear resistance.
4. Market prospects of polyester hot melt wire
With the increasing global demand for environmentally friendly and high-performance materials, the market prospects of polyester hot melt wire are broad. Its low melting point, high strength, environmental protection and other characteristics give it a significant competitive advantage in the textile industry. For international wholesale buyers, choosing polyester hot melt wire can not only meet customers’ demand for high-quality products, but also conform to the trend of global sustainable development.
5. Summary
As a new type of functional fiber, polyester hot melt wire is changing the pattern of the textile industry with its unique physical and chemical properties. Compared with traditional materials, polyester hot melt wire shows significant advantages in strength, wear resistance, heat resistance, environmental protection and other aspects. Whether it is shoe material manufacturing, home textile curtains, or automotive interior and clothing manufacturing, polyester hot melt wire can provide excellent performance and sustainable solutions. For international wholesale buyers, choosing polyester hot melt yarn is undoubtedly a wise move. It can not only enhance the market competitiveness of products, but also provide customers with more environmentally friendly and efficient choices.
