What do ss and sms nonwovens mean? What's the difference

SS is spunbonded nonwoven fabric and spunbonded nonwoven fabric, and the two-layer net is hot rolled. SMS is spun-bonded nonwoven fabric and melt-blown nonwoven fabric and spun-bonded nonwoven fabric, hot-rolled three-layer network.

1. Different properties: non-woven fabric consists of fixed fibers or random fibers. SMS nonwovens is a kind of spunbonded and sprayed composite product.

2. Different characteristics: SMS non-woven fabric has the characteristics of high strength, good filtration performance, non-adhesion and non-toxicity. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustion-supporting, easy to decompose, non-toxic, non-irritating and colorful.

3. Different uses: SMS non-woven fabrics are mainly used for medical and health labor insurance products, such as surgical gowns, surgical caps, protective gowns, hand washing gowns, handbags, etc. Non-woven fabrics are used for home improvement non-woven fabrics, wall covering, tablecloths, beds 526 1 sheets, bedspreads, etc.

Extended data:

Non-toxic and tasteless, highly effective antibacterial. Through special processing equipment, the production performance of antistatic, alcohol-resistant, waterproof and waterproof is achieved.

Non-woven fabric features: durable and disposable. Insulation and conductivity. Soft and hard. Fineness and scalability. Isotropic, anisotropic. Filter, breathable, airtight. Elastic stiffness. Lightweight, loose and warm. As thin as cicada wings and as thick as felt.

Waterproof and moisture permeable. Ironing, sewing and shaping. Flame retardant and antistatic. Water-permeable, waterproof, wear-resistant and fluffy. Folding resistance, good elasticity, high hygroscopicity and good water repellency.

1, light weight: polypropylene resin as the main raw material, with a specific gravity of only 0.9, only three-fifths of cotton, fluffy and good hand feeling.

2, soft: made of fine fibers (2-3d), hot melt welding. The finished product has moderate softness and comfortable feel.

3. Diversion ventilation: polypropylene sheet does not absorb water, and its moisture content is zero. The finished product has good conductivity, consisting of 100% fiber, high porosity, good air permeability, easy to keep the cloth surface dry and easy to wash.

4. Non-toxic and non-irritating: the product adopts FDA food-grade raw materials, contains no other chemical components, has stable performance, is non-toxic and tasteless, and has no irritation to the skin.

5. Anti-bacterial and anti-chemical agent: Polypropylene is a chemical passivation substance, which is not eaten by insects and can isolate the corrosion of bacteria and insects in liquid; Antibacterial and alkali corrosion resistant, and the strength of the finished product will not be affected by corrosion.
