Temperature Applicable Range of Polyester Hot Melt Wire and Its Application
Introduction
As a functional fiber, polyester hot melt wire plays an important role in the modern textile industry. Through a special production process, it can melt at a specific temperature and bond with other fibers to achieve multiple functions. This article will explore the temperature applicable range of polyester hot melt wire and analyze its performance in different application scenarios.
Temperature Applicable Range of Polyester Hot Melt Wire
The melting point range of polyester hot melt wire is usually between 85℃ and 180℃. This wide melting point range is achieved by adjusting the raw material properties and production process to meet the needs of different application scenarios. The following are the melting points and characteristics of several common polyester hot melt wires:
Variety Melting Point (℃) Characteristics and Applications
PEF510 110 Low melting point, suitable for hot air shoe upper manufacturing, seamless clothing seam locking, etc., with high bonding strength.
PEF512 110 Moderate fineness, suitable for soft gauze curtains, vertical curtains, etc., soft to the touch and high strength.
Polyester sheath-core low-melting point filament 160-170 Various deniers (such as 75D, 100D, 150D, etc.), high strength, easy to weave, suitable for circular knitting machines, high-speed warp knitting, etc.
In addition, there are some special-purpose polyester hot melt yarns whose melting points may be higher or lower to adapt to specific processing conditions.
Temperature characteristics of polyester hot melt yarn
The performance of polyester hot melt yarn under temperature changes is the key to its application. When the temperature reaches its melting point, the hot melt yarn will gradually melt and form a sticky substance, which will bond other fibers together. This characteristic gives it a unique advantage in a variety of textile processes. For example, in dry heat or wet heat, the hot melt yarn can quickly bond fibers to form a strong bond.
Application fields of polyester hot melt yarn
The wide application of polyester hot melt yarn is mainly due to its wide temperature application range and good bonding properties. The following are its applications in different fields:
1. Textile field
In the textile industry, polyester hot melt yarn is often used to manufacture hot air method shoe uppers, yarns, clothing seamless seams and other products. Its low melting point property enables it to achieve bonding without damaging other fibers, thereby improving production efficiency and reducing costs.
2. Household items
Polyester hot melt yarn is also widely used in the manufacture of household items such as curtains, window screens, and sofa fabrics. Its good bonding properties and heat resistance enable it to maintain the shape and structure of the fabric while providing a soft feel.
3. Industrial use
In the industrial field, polyester hot melt yarn can be used in the production of products such as carbon fiber cloth shaping and chenille yarn. Its high-temperature bonding performance can ensure the stability and durability of the product in complex environments.
Future development of polyester hot melt yarn
With the continuous advancement of technology, the performance and application range of polyester hot melt yarn will be further expanded. For example, by improving the production process, its melting point can be further reduced, allowing it to play a role in more low-temperature application scenarios. In addition, the needs of environmental protection and sustainable development will also drive polyester hot melt yarn to develop in a more environmentally friendly direction.
Conclusion
Polyester hot melt yarn has a wide temperature range, ranging from 85℃ to 180℃, enabling it to meet the needs of a variety of application scenarios. Its good bonding properties and heat resistance make it widely used in textiles, household goods and industrial fields. With the continuous advancement of technology, the performance and application range of polyester hot melt yarn will be further expanded, providing more possibilities for the development of the textile industry.
