Low Melt Polyester Fiber

Low-melt polyester fiber refers to fiber with a melting point from 90 degrees to 220 degrees. 110℃ LMF is the most common in the market. When heated to 110-150 ℃, the sheath layer can melt and generate a sheath-core or side-by-side structure. It can be mixed with other fibers or be used alone. The applications lie in imitation silk cotton, non-adhesive cotton, stiff cotton, needled cotton, spinning, and carpet.

4080 Low-melt Fiber
Low-melt polyester staple fiber is called hot-melt cotton or 4080 in the non-woven fabric industry. It is made from low-melting polyester and conventional polyester. After melting, it is extruded from the same spinning micropore to form a composite fiber with a sheath-core structure. The melting point of the sheath layer is generally 110-180 degrees Celsius, and the core layer is 256-260 degrees Celsius. The melting point of the most common low-melting staple fibers currently on the market is generally controlled at around 110℃. Low-melting polyester and conventional polyester have good compatibility. Under the condition of lower heating temperatures, the skin layer melts and the core layer still maintains the physical structure. After cooling, it has good adhesion and high bonding strength. It replaces traditional glue since it has the characteristics of low hot-melt bonding temperature, fast bonding, and high peel strength. It is widely used in imitation silk cotton, filter materials, shoe materials, mattresses, and other fields. Low-melt fiber plays a role in physical bonding in manufacturing non-woven fabrics. And its replacement of chemical binders can reduce pollution and costs.
