SMMS offers soft, sensitive fabrics that are suitable for skin compatibility to replace pure cotton clothing. The continuous filaments that make up the spunbond layer have good breaking strength and elongation. Continuous microfibre, which makes up the melt-blown layer and has good moisture, bacterial, and dust barrier properties. It can withstand high water pressure, has good air permeability, and can withstand acid and alkali well.

A four-die spin Using four sets of die heads (S/M/M/S), melt nonwoven fabric is a type of composite nonwoven fabric that combines spunbond with melt blown technologies. Spunbonded non-woven fabric (S), melt blown non-woven fabric (M), melt blown non-woven fabric (M), and spunbonded non-woven fabric (S) are the "four die heads" that stand in for these materials, respectively.
