The difference between SMS non-woven fabric, SS non-woven fabric and coated non-woven fabric

SS non-woven fabric is a kind of spunbonded non-woven fabric. It is not difficult to tell from the name that it is a fabric from double spinnerets, which makes the produced non-woven fabric more uniform and stronger than single S non-woven fabric .


SMS non-woven fabric is a composite non-woven fabric. It has more M layers than SS non-woven fabric. It combines the advantages of spunbond and meltblown. The spunbond layer increases the vertical and horizontal strength of the product, while the superfine fiber The meltblown layer has greatly improved the product's appearance uniformity and water resistance.


Laminated non-woven fabric is also called laminating composite non-woven fabric, which is to coat a plastic film on the non-woven fabric. It is a product formed by coating a plastic film heated to a hot melt state on the non-woven fabric and cooling it at a high temperature. Therefore, the coated non-woven fabric has the characteristics of high strength, high barrier properties, and high hydrostatic pressure resistance.


The raw material of SS non-woven fabric and SMS non-woven fabric is polypropylene, namely PP pellets. The raw materials of coated non-woven fabrics are polyethylene and non-woven fabrics.


In terms of air permeability, SS non-woven fabrics are highly air-permeable, followed by SMS non-woven fabrics, and laminating non-woven fabrics are impermeable.
