What do S, SS, SMS, SMMS in non-woven fabrics mean?

1. S: Spunbond non-woven fabric = single-layer fiber web hot rolled;

2. SS: Spunbond non-woven fabric + spunbonded non-woven fabric = two-layer fiber web hot rolled;

3. SMS: Spunbond non-woven fabric + meltblown non-woven fabric + spunbonded non-woven fabric = three-layer fiber web hot rolled;

4. SMMS: Spunbond non-woven fabric + melt-blown non-woven fabric + melt-blown non-woven fabric + spun-bonded non-woven fabric = four-layer fiber web hot rolled.

SMMS non-woven fabric is a composite non-woven fabric, which is a composite product of spunbond and meltblown; it is an extension of SMS non-woven fabric.

Extended information:

It is non-toxic, tasteless, and efficient in separating bacteria. Through special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water repellent and water production properties.

Features of non-woven fabrics: durable, disposable. Insulating and conductive. Softness and stiffness. Density and expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity and stiffness. Light, loose and warm. Thin as a cicada’s wings, thick as felt.

Waterproof and breathable. Ironing, stitching, and compression molding. Flame retardant and antistatic. Water-permeable, waterproof, abrasion-resistant, and flocking. Wrinkle resistant, good elasticity, high moisture absorption, water repellency.

1. Lightweight: 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-repellent and breathable: Polypropylene slices do not absorb water, have zero water content, and have good water-repellent properties. They are made of 100% fiber and are porous and air-permeable. It is easy to keep the cloth dry and easy to wash.

4. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, is non-toxic, non-odor, 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.
