What are the characteristics of SMS composite non woven fabrics? 2020-10-27

SMS composite non woven fabric characteristics, SMS composite non woven fabric use, SMS, SMMS non woven fabric is a new type of composite material, it is two-layer spunbond and one layer of meltblown composite or two-layer spunbond and two-layer meltblown composite non woven fabric.

Features of SMS non woven fabrics: durability. Insulating and non-conductive. Softness and stiffness. Density and expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity and stiffness. Light, loose and warm. Thin as cicada wings, thick as felt. Waterproof and breathable. Ironing, sewing, and molding. Flame retardant and antistatic. Water-permeable, waterproof, abrasion-resistant and flocking. Wrinkle resistance, good elasticity, high moisture absorption and water repellency.

1. Light weight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, which is only three-fifths of cotton. It is fluffy and has a good hand feeling.

2. Soft: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished product is moderately soft and comfortable.

3. Water repellency and breathability: Polypropylene slices do not absorb water, have zero moisture content, and have good water repellency. The 100% fiber composition is porous and has good air permeability. It is easy to keep the cloth dry and easy to wash.

4. No irritation: The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, no peculiar smell, and does not irritate the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by erosion.

6. Antibacterial: The product is water-repellent, not moldy, and can isolate the corrosion of bacteria and insects in the liquid, and is not moldy.

7. Good physical properties: It is made of polypropylene spun yarn directly laid into a net and thermally bonded. The product strength is better than ordinary staple fiber products, the strength is non-directional, and the vertical and horizontal strengths are similar.
