ES fiber is a new type of thermal bonding composite fiber, its English name is "Ethylene-Propylene Side By Side", is a polyolefin fiber. The uniqueness of ES fiber lies in its bicomponent structure, in which the core layer is polypropylene, the role of the main fiber, and the skin layer is polyethylene, which is mainly responsible for hot melt bonding.
This structure allows the ES fibers in the nonwoven material to improve the structure of the material by effective and uniform bonding of the fiber intersections within the web, thereby increasing the strength of the material. In addition, the hot melt bonding temperature range of the ES fiber is wide, which makes the production process easy to control while maintaining the soft feel of the product. Due to its excellent performance, ES fiber has received high ratings worldwide.
The advantages of S fiber not only include improving the structure of non-woven materials and improving the strength of the material, but also in its wide hot melt bonding temperature range, which makes the production process easier to control. In addition, this fiber has high productivity, low energy consumption, and soft feel, which are reasons for its popularity.
Due to these characteristics of ES fiber, it has applications in many fields, such as sanitary materials, packaging materials, medical supplies, etc.
