Do you know Hot Melt Polyester Yarn?

Hot Melt Polyester Yarn, also known as hot melt polyester yarn, is a polyester fiber with a special structure. The following is a detailed analysis of it:

1. Composition and characteristics

Hot melt polyester yarn is composed of two polyester materials with different softening points: one with a lower softening point, located at the tip or surface of the fiber; the other with a higher softening point, located in the core of the fiber. This special structure makes the hot melt polyester yarn melt and bond together when heated, while the polyester part with a high softening point remains solid, providing structural support for the yarn.

2. Production process

During the production process, the two polyester materials are dried and then spun by conjugate spinning technology. During the spinning process, a special spinneret is used to form fibers with a specific cross-sectional shape and structure. The resulting hot melt polyester yarn has multiple ridge structures, and the tips of these ridge structures are composed of low softening point polyester, and the core is composed of high softening point polyester.

3. Application fields

Hot-melt polyester yarn has a wide range of applications in many fields due to its unique structure and properties. For example, it can be mixed with cotton wool to make quilts and pillows with excellent thermal insulation performance; it can also be used to make various textiles that require hot-melt bonding, such as seamless underwear, sportswear, etc. In addition, hot-melt polyester yarn also has good elasticity and recovery, which makes it have a wide range of application prospects in the manufacture of elastic fabrics and clothing.

In summary, hot-melt polyester yarn is a new type of polyester fiber with special structure and properties, and its application field is wide and has broad prospects.
