What is SMS Nonwoven fabric?
SMS non-woven 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.
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 dipped, rolled, dried and cooled in a dip tank with functional additives to obtain the desired multi-functional SMS non-woven fabric.
Features of SMS non-woven fabrics:
Durable, 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.
SMS non-woven fabrics can be applied in different fields according to the thickness:
1.Thin SMS non-woven fabrics (10-25gsm), because of its waterproof and breathable properties, are suitable for sanitary market, such as sanitary napkins, sanitary pads, baby diapers, adult incontinence diapers, side leakage prevention edge and backing, etc. .
2.Medium-thickness SMS non-woven fabric (25-50gsm), suitable for medical use, making surgical gowns, surgical wraps, surgical drapes, sterilization bandages, wound patches, plaster patches, etc. It is also suitable for industrial use. Production of work clothes, protective clothing, etc. smS products are more suitable as high-quality medical protective equipment materials because of their good isolation performance, especially SMS products 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.
