The differences between S, SS, SMS and SMMS in nonwovens are as follows:
S: Spunbonded nonwoven fabric = single-layer fiber net hot rolled;
SS: Spinbonded non-woven fabric + Spinbonded non-woven fabric = two layers of hot rolled fiber net;
SMS: Spinbonded non-woven fabric + melt-blown non-woven fabric + Spinbonded non-woven fabric = three layers of fiber net hot rolled;
SMMS: Spunbonded non-woven fabric + melt-blown non-woven fabric + melt-blown non-woven fabric + spunbonded non-woven fabric = four layers of fiber network from hot rolling
Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustion-supporting, easy decomposition, non-toxic and non-irritating, colorful, low price, recycling and reuse, etc. Such as the use of polypropylene (PP material) granule as raw material, after high temperature melting, spinneret, paving, hot rolling continuous one-step production.
Extended Information:
Non-toxic and tasteless, highly effective bacteria-proof. Through the special treatment of the equipment, it can achieve the properties of antistatic, anti-alcohol, anti-plasma, water-repellant and water-producing.
Features of non-woven fabric: durability, disposable. Insulating, conducting electricity. Flexibility, stiffness. Fineness, expansibility. Anisotropy, anisotropy. Filterability, breathable and waterproof. Flexibility, rigidity. Light, loose, warm. Thin as a cicada and thick as a felt.
Water proof and permeable to moisture. Ironing, stitching, moulding. Flame retardant and antistatic. Permeable, waterproof, wear-resistant and fleecy. Wrinkle resistance, good elasticity, high moisture absorption, water repellent.
1. Light quality: polypropylene resin as the main raw material, specific gravity is only 0.9, only three fifths of cotton, with fluffiness, good hand feel.
2. Soft: composed of fine fibers (2-3D), light point hot melt bonding forming. The finished product has moderate softness and comfort.
3. Water and air permeability: polypropylene slice does not absorb water, water content is zero, the finished product water quality is good, composed of 100% fiber with porosity, good air permeability, easy to keep the cloth dry, easy to wash.
4. Non-toxic, non-irritating: the product is made of food grade raw materials in line with FDA, without other chemical ingredients, stable performance, non-toxic, no odor, and no irritation to the skin
5. Antimicrobial and chemical resistance: polypropylene is a chemically blunt material, not moth-eaten, and can isolate bacteria and insect erosion in the liquid; Antibacterial, alkali corrosion, the finished product does not affect the strength due to erosion.
