1, S: spunbond nonwoven = single-layer fiber mesh hot-rolled;
2, SS: spunbond nonwoven + spunbond nonwoven = two-layer fiber mesh hot-rolled;
3, SMS: spunbond nonwoven + meltblown nonwoven + spunbond nonwoven = three-layer fiber mesh hot-rolled;
4, SMMS: spunbond nonwoven + meltblown nonwoven + meltblown nonwoven + SMMS: spunbond nonwoven fabric+meltblown nonwoven fabric+meltblown nonwoven fabric+spunbond nonwoven fabric=four layers of fiber mesh hot rolled
SMMS nonwoven fabric belongs to composite nonwoven fabric, which is the composite product of spunbond and meltblown; it belongs to the extension of SMS nonwoven fabric.
Extension:
.Non-toxic, odorless, efficient bacteria isolation. Through the special treatment of the equipment, it can achieve the performance of anti-static, anti-alcohol, anti-plasma, water rejection and water production.
Features of nonwoven fabric: durable, disposable. Insulation, conductive. Softness, rigidity. Fine density, expansion. Isotropic, anisotropic. Filtering, breathable and impermeable. Elasticity, stiffness. Light, loose, warm. Thin as a cicada, thick as felt.
Waterproof and breathable. Ironing, sewing, molding. Flame retardant, anti-static. Water-permeable, waterproof, abrasion-resistant, downy. Wrinkle resistant, good elasticity, high moisture absorption, water repellency.
1. Lightweight: polypropylene resin as the main raw material, specific gravity is only 0.9, only three-fifths of cotton, with fluffy, feel good.
2. Softness: composed of fine fibers (2-3D) light spot hot melt bonding molding. The finished product is moderately soft and comfortable.
3. Water repellent and breathable: Polypropylene slices do not absorb water, water content is zero, the finished product has good water repellency, composed of 100% fibers with porous, breathable, easy to keep the fabric dry, easy to wash.
4. Non-toxic, non-irritating: the product is produced with FDA food-grade raw materials, does not contain other chemical components, stable performance, non-toxic, odorless, non-stimulating skin.
5. Antibacterial, anti-chemicals: polypropylene is a chemically passive substance, not insect, and can isolate the presence of bacteria and insects within the liquid erosion; antibacterial, alkali corrosion, finished products do not affect the strength of erosion.
