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.
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.
SMS nonwoven use
SMS non-woven materials can be used in different fields from thin and thick types of products:
1. Thin SMS non-woven fabric (10-25gsm), because of its waterproof and breathable properties, is especially suitable for the sanitary market, such as the side leakage prevention edge and backing of sanitary napkins, sanitary pads, baby diapers, adult incontinence diapers Wait.
2. Medium thickness SMS non-woven fabric (25-50gsm), suitable for use in medical field, making surgical gowns, surgical wraps, surgical coverings, sterilization bandages, wound stickers, plaster stickers, etc. It is also suitable for industrial use, For making work clothes, protective clothing, etc. smS products are more suitable as high-quality medical protective equipment materials due to their good isolation performance, especially those that have undergone three-antibody and antistatic treatment, and have been widely used around the world.
3. Thick SMS products (>55gsm) are widely used as high-efficiency filter materials for various gases and liquids, and are also excellent high-efficiency oil-absorbing materials. They are used in industrial wastewater degreasing, marine oil pollution cleaning, and industrial rags.
The medical non-woven SMMMS is made of 100% polypropylene slices as raw material, which is non-toxic, non-fiber shedding, and has a high effective antibacterial rate; the cloth surface is uniform and full, which can effectively improve product quality.
SMMMS can replace pure cotton fabric, soft, delicate and skin-friendly. The spunbond layer consists of continuous filaments with good breaking strength and elongation. The meltblown layer is composed of continuous ultra-fine fibers, which has a good barrier effect on moisture, bacteria, dust, etc. It has high water pressure resistance, good air permeability, and good acid and alkali resistance. Applicable to various sterilization methods such as high and low temperature; one-time use, no need for recycling and cleaning; in line with environmental protection requirements, easy to degrade or incinerate; effectively prevent hospital cross-infection, reduce hidden costs of treatment, and improve infection control rate; no multiple use Damaged consumption; no washing cost; stored under qualified conditions, the aseptic validity period is 180 days.
Three-resistant non-woven fabric SMMS is made of spunbond non-woven fabric + melt-blown non-woven fabric + melt-blown non-woven fabric + spun-bonded non-woven fabric, and four layers of fiber web are hot-rolled. It has all the characteristics of ordinary SMMS non-woven fabrics; anti-alcohol up to grade 10 (ie 100% anti-alcohol); anti-static capacity of 108-1012; anti-oil; anti-plasma; mainly used in surgical gowns, surgical towel, surgical bag Cloths, medical sheets, hand wash clothes, isolation suits, lab coats, advanced protective clothing and other protective series products can be made in different colors according to different customers' preferences.
The ordinary disposable isolation fabrics on the market are mainly made of PP polypropylene fiber or SMS or ordinary non-woven fabrics (PP+PE film). There are also microporous protective clothing mainly made of non-woven fabrics (PTFE composite fabrics), with a conventional gram weight of 80-100g/m2, which has the characteristics of preventing microbial penetration and good blood permeability.
SMS nonwoven special processing
Various special treatments are performed on non-woven fabrics to meet customer requirements for various special properties of non-woven fabrics. The treated non-woven fabric has anti-alcohol, anti-blood and anti-oil functions, and is mainly used in medical surgical gowns and surgical drapes.
Antistatic treatment: Antistatic non-woven fabrics are mainly used as materials for protective equipment with special environmental requirements for static electricity.
Water-absorbing treatment: Water-absorbing non-woven fabrics are mainly used in the production of medical consumables, such as surgical hole towels, surgical pads, etc.
Flame retardant treatment: flame retardant non-woven fabrics are widely used in furniture products and aviation supplies.
Antibacterial, deodorant and photocatalyst effect treatment: This kind of non-woven fabric is mainly used in the field of household products.
Anti-ultraviolet treatment: Anti-ultraviolet and anti-aging non-woven fabrics are mainly used in agricultural mulch, car covers and other fabrics, where sunscreen and anti-aging effects are required.
Fragrance treatment: Fragrance non-woven fabrics are used in sanitary products (mint, lemon, lavender, etc.). If you also take non woven fabric slitting machine into consideration, then don’t hesitate to click the link to discover more!
