SMS non-woven fabrics and non-woven fabrics, SS film non-woven fabrics

SS non-woven fabric is a kind of spun-bonded non-woven fabric, it is not hard to see from the name, it is of the spinneret of cloth, make the production of non-woven fabric more uniform than single S non-woven, higher strength. SMS non-woven belong to the composite non-woven fabric, it's more than SS non-woven M layer, it incorporates the advantages of spun-bonded and melt-blown spun-bonded layers make products to increase the lateral strength, and melt-blown superfine fiber layer has greatly improved the appearance of the product with sex and water resistance. Composite non-woven non-woven fabric and film laminating, plastic film is coated on the non-woven last, is the high temperature heating into a state of hot melt plastic coating on the non-woven cooling formation of the product. So the film non-woven fabric has high tenacity, high barrier property, the following characteristics: high hydrostatic pressure. SS non-woven and SMS non-woven raw material is polypropylene, namely PP aggregate. The raw material is polyethylene and film non-woven non-woven. From the air permeability, SS non-woven fabric permeability is strong, followed by SMS non-woven fabrics, film is not breathable non-woven fabric.
