And overcome the defects of the existing bonded composite non-woven products, such as hard feel and lack of elasticity, and further expand its application scope and further expand its application scope.



Needle-punched non-woven fabric:

Its main components are polyester staple fiber and polypropylene fiber. The invention uses polypropylene fiber as one of the components of the non-woven fabric, which changes the characteristics of the polyester staple non-woven fabric, so that the product has a certain stiffness, strength, small elongation, and has a certain tensile resistance. At the same time, this kind of Man-made fibers have a better touch than natural fibers, and are more suitable for close use by humans, especially without any harmful chemical components.
