SMS Nonwoven Fabrics
SMS nonwoven fabric is made of three layers of spunbond non-woven fabric + melt-blown non-woven fabric + spun-bonded non-woven fabric by hot rolling. It is a composite non-woven fabric. It is a composite product of spunbond and melt-blown non-toxic. Odorless, efficient bacteria isolation. Through the special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water-repellent and water-producing properties.Get more news about Smmss Non-woven Non-woven Fabric Production Equipment,you can vist our website!
SMS production process
Add 3%-7% masterbatch in SMS non-woven spinning production; preparation of functional auxiliaries: functional auxiliaries are mixed with water repellent, flame retardant, antistatic agent, penetrant and water; The SMS non-woven fabric was placed in a dipping solution tank with functional additives, dipped, rolled, dried and cooled to obtain the desired multifunctional smS non-woven fabric.
At present, the main processes of manufacturing SMS non-woven fabrics include three methods: "one-step method", "two-step method" and "one-step half method".
SMS product performance
Non-toxic and tasteless, efficient bacteria isolation. Through the special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water-repellent and water-producing properties.
Features of non-woven fabrics: Durability, Disposable. Insulating, non-conducting. Softness, stiffness. fineness, expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity, stiffness. Light, relaxed, warm. Thin as cicada wings, thick as felt. Waterproof and breathable. Ironing, sewing, moulding. Flame retardant, antistatic. Water-permeable, waterproof, wear-resistant, fleece. Wrinkle resistance, good elasticity, high moisture absorption, water repellency.
1. Light weight: Polypropylene resin is used as the main raw material, with a specific gravity of only 0.9, only three-fifths of cotton, with fluffy and good hand feeling.
2. Soft: It is composed of fine fibers (2-3D) and formed by light point-like hot melt bonding. The finished product is moderately soft and comfortable.
3. Water repellency and breathability: Polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water repellency. It is composed of 100% fiber, which is porous and has good air permeability. It is easy to keep the cloth surface dry and easy to wash.
4. Non-toxic and non-irritating: The product is produced with FDA-compliant food-grade raw materials, without other chemical components, with stable performance, non-toxic, no peculiar smell, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.
6. Good physical properties: It is made of polypropylene spinning directly spread into a mesh and thermally bonded. The strength of the product is better than that of general staple fiber products, the strength is non-directional, and the vertical and horizontal strengths are similar.
