Properties of SMS non-woven fabric
SMS non-woven fabric full name: Spunbond+Meltblown+Spunbond Nonwovens, made of spunbond non-woven fabric + meltblown non-woven fabric three layers of hot rolled fiber mesh, belongs to composite non-woven fabric, it is spunbond and meltblown composite products, non-toxic, tasteless, highly effective bacteria isolation. Through special treatment of the equipment, it can achieve anti-static, anti-alcohol, anti-plasma, water-repellent and water-producing properties.
Characteristics of non-woven fabric: durability, disposable. Insulated, not conductive. Softness, stiffness. Fineness, expansibility. Isotropy, anisotropy. Filterable, breathable and watertight. Elasticity, stiffness. Light, loose, warm. Thin as cicada wings, thick as felt. Waterproof and permeable to moisture. Ironing, stitching, molding. Flame retardant, antistatic. Water permeable, waterproof, wear-resistant, velvet. Fold resistance, good elasticity, high moisture absorption, water repellent.
1. Light weight: With polypropylene resin as the main raw material, the proportion is only 0.9, only three-fifths of cotton, fluffy, good hand feel.
2. Soft: composed of fine fibers (2-3D) light hot melt bonding molding. The finished product has moderate softness and comfortable feeling.
3. Dials water, breathable: polypropylene slice does not absorb water, moisture content is zero, the finished product is good water, composed of 100% fiber with porous, good air permeability, easy to keep the cloth dry, easy to wash.
4. Non-toxic and non-irritating: The product is made of food grade raw materials conforming to FDA, without other chemical components, stable performance, non-toxic, no odor, no skin irritation.
5. Antibacterial and anti-chemical agents: polypropylene is a chemical blunt substance, not moth eaten, and can isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, finished products do not affect the strength due to erosion.
6, good physical properties: by polypropylene spinning directly spread into a mesh of hot bonding, product strength is better than the general staple fiber products, strength is non-directional, vertical and horizontal strength is similar.
Applications of SMS non-woven fabric
SMS non-woven materials from thin to thick types of products can also be used in different areas:
1. Thin SMS non-woven fabric (10-25gsm), because of its waterproof and breathable, especially suitable for the health market, such as as sanitary napkins, sanitary pads, baby diapers, adult incontinence diaper side leakage and back lining.
2. Medium thickness SMS non-woven fabric (25-50gsm), suitable for medical use in the production of surgical gowns, operating bag cloth, surgical cover cloth, sterilization bandages, wound stickers, plaster stickers, etc., also suitable for industrial use, for the production of work clothes, protective clothing, etc. SMS products have been widely used in the world because of their good isolation performance, especially SMS products that have been treated with triple resistance and antistatic, which are more suitable as high-quality medical protective materials.
3. Thick SMS products (> 55gsm), widely used as a variety of gas and liquid efficient filtration material, but also an excellent efficient oil absorption material, used in industrial wastewater oil removal, Marine oil cleaning and industrial rag.
Medical non-woven fabric SMMMS, 100% polypropylene slice as raw material, no toxicity, no fiber shedding, high effective bacteriostatic rate; Cloth surface uniformity is good, full, can effectively improve product quality.
SMMMS can replace pure cotton fabric fabric, feel soft, delicate, skin friendly. Spunbonded layer is composed of continuous filament and has good breaking strength and elongation. The melt-blown layer is composed of continuous microfibers, which has good barrier effect on water, bacteria, dust, etc. It has high water pressure resistance and good air permeability, good acid and alkali resistance. Suitable for high and low temperature sterilization methods; Disposable use, no need to recycle, cleaning; Meet environmental protection requirements, easy to degrade or incinerate; Effectively prevent hospital cross infection, reduce the hidden cost of treatment, improve infection control rate; No multiple use damage consumption; No washing cost; Stored under acceptable conditions, sterile validity up to 180 days.
Three anti non-woven fabric SMMS is made of spunbonded non-woven fabric + meltblown non-woven fabric + meltblown non-woven fabric + spunbonded non-woven fabric, four layers of fiber mesh hot rolled. Have all the characteristics of ordinary SMMS non-woven fabric; Alcohol resistance up to level 10 (i.e. 100% alcohol resistance); Antistatic capacity up to 108-1012; Oil proof; Anti-plasma; Mainly used in operating clothes, operating towel, operating bag cloth, medical sheets, hand washing clothes, isolation clothes, lab clothes, advanced protective clothing and other protective products, can be made according to different customers like different colors.
Common disposable isolation fabrics on the market are mainly PP polypropylene or SMS or ordinary coated non-woven fabric (PP+PE film), the general weight of 35-50g/m2, excellent protective performance, breathable and comfortable. There are microporous protective clothing main material using film coated non-woven fabric (PTFE composite fabric), conventional weight 80-100g/m2, with resistance to microbial penetration, blood through the characteristics of good.
