2.SS: spunbonded nonwoven fabric+spunbonded nonwoven fabric = two-layer net hot rolling;

3.SMS: spunbonded nonwovens+meltblown nonwovens+spunbonded nonwovens = three-layer net hot rolling;

4.SMMS: spunbonded nonwoven fabric+meltblown nonwoven fabric+spunbonded nonwoven fabric = four-layer hot-rolled mesh.

SMMS nonwovens belong to composite nonwovens, which is a composite product of spunbonding and meltblowing. Belonging to the extension of SMS non-woven fabric.

Extended data:

Non-toxic and tasteless, high-efficiency isolation of bacteria. Through the special treatment of the equipment, the performance of antistatic, alcohol-resistant, plasma-resistant, water-repellent and water-producing can be achieved.

Features of non-woven fabrics: durable and disposable. Insulation and conductivity. Flexibility and rigidity. Good. Inflate. Isotropic, anisotropic. Filtration, air permeability and water impermeability. Elasticity and rigidity. 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. Wrinkle resistance, good elasticity, high hygroscopicity and water repellency.

1. light weight: polypropylene resin is the main raw material, and its specific gravity is only 0.9, which is only three-fifths of that of cotton. It's fluffy and feels good.

2. Flexibility: made of fine fibers (2-3D) and made of hot-melt bonding of light spots. The finished product has moderate softness and is comfortable to wear.

3. Water absorption and air permeability: polypropylene chips do not absorb water, and the water content is zero, so the finished product has good water absorption, is composed of 100% fiber, and has good porosity and air permeability, and is easy to keep the cloth surface dry and easy to wash.

4. Non-toxic and non-irritating: This product is made of food-grade raw materials conforming to FDA, and contains no other chemical components, with stable performance, non-toxic, tasteless and non-irritating to skin.

5. Antibacterial and chemical resistant 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, alkali corrosion resistant, the strength of the finished product will not be affected by corrosion.
