The difference between S, SS, SMS, SMMS in non-woven fabrics

The differences between S, SS, SMS and SMMS in non-woven fabrics are as follows:


S: Spunbond non-woven fabric u003d single-layer fiber web hot rolled;


SS: Spunbond non-woven fabric + spunbonded non-woven fabric u003d two-layer fiber web hot rolled;


SMS: Spunbond non-woven fabric + meltblown non-woven fabric + spunbonded non-woven fabric u003d three-layer fiber web hot rolled;


SMMS: Spunbond non-woven fabric + melt-blown non-woven fabric + melt-blown non-woven fabric + spunbond non-woven fabric u003d four-layer fiber web hot rolled


The production line equipment is mainly different in spinneret components. Spunbond fabrics use spinnerets and meltblown spinnerets. The process is different, and the process is basically the same.


The main equipment, the best in the world are: Reifenhaus production line, as well as Japan’s NHK. The domestic meltblown die head cannot meet the technical requirements. Spunbond production equipment is still possible. Dalian Hualun, Wenzhou Yonghong Chemical Fiber is pretty good.
