Yuzhimu nonwoven fabric thermal bonding technology

The technical solution adopted for high-performance non-woven fabrics is a Long fiber bicomponent nonwoven fabric. The fibers of the non-woven fabric are skin core composite fibers, which are composed of skin material and core material. The skin material is selected from PA6 (nylon material), and the core material is selected from PET. When selecting the skin material and core material, the melting point of the skin material should be lower than that of the core material, in order to achieve strong adhesion in the non-woven fabric product.

Compared with hot-rolled non-woven fabrics of the same square gram weight, they are more fluffy, the thickness of the cloth is increased, and the air permeability is greatly improved, which is much higher than conventional spunbond products. It is specially suitable for use as filter materials. It not only makes up for the shortcomings of existing filament non-woven fabrics, but also maintains the original characteristics of various filaments such as high strength, high temperature resistance, aging resistance, UV resistance, corrosion resistance, sound insulation, and moth-proofing.and moth-proofing.
