What Are The Characteristics Of SMS Composite Non Woven Fabric?

SMS, SMMS Non Woven Fabric is a new type of composite material, which is a Nonwoven Fabric with two layers of spunbond and one layer of meltblown composite or two layers of spunbond and two layers of Meltblown Nonwoven composite.

Features of SMS non woven fabric: Durable, insulating, non - conductive, soft, stiff, fine, swelling, isotropic, anisotropic, breathable and impermeable, light. It is as thin as a cicada's wing and as thick as a felt. It is waterproof and breathable. It's ironed, sewn, and molded. It has the functions of flame retardant and antistatic. It is also water - permeable, abrasion - resistant, fleece - resistant, wrinkle - resistant, elastic, highly absorbent, and water - repellent.

1. Light weight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, only three - fifths of cotton, with fluffy and good hand feeling.
2. Soft: It is composed of fine fibers ( 2 - 3 D ) and is formed by light point hot melt bonding. The finished product is moderately soft and comfortable.
3. Water repellent and breathable: Polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water repellency. It is composed of 100 % fiber, which has porosity and good air permeability. It is easy to keep the cloth surface dry and easy to wash.
4. Non - irritating: The Filter Fabric is produced with FDA - compliant food - grade raw materials. It does not contain other chemical components. It has stable performance, no peculiar smell, and does not irritate the skin.
5. Antibacterial and anti - chemical agents: Polypropylene is a chemically inert substance and is not moth - eaten. And it can isolate the erosion of bacteria and insects in the liquid. Antibacterial, alkali corrosion, the finished product does not affect the strength due to erosion.
6. Antibacterial property: The filter fabric is water - repellent and not moldy. It can isolate the erosion of bacteria and insects in the liquid without mildew.
7. Good physical properties: Nonwoven Filter Cloth Material is made of polypropylene spinning directly spread into a mesh and thermally bonded. The strength of the product is better than that of general staple fiber products. The strength is non - directional, and the vertical and horizontal strengths are similar.
