PP non woven fabric for face mask
Some concepts of non woven cloth
S: Spun bond non woven
M: Melt blown fabric
S: Spun bonded non woven = single layer web hot rolled
SS: spun bond non woven + spun bond non woven = hot rolled from two layers of fiber web
SSS: spun bond non woven + spun bond non woven + spun bond non woven = three-layer web hot rolled
SSSS: spun bond non woven + spun bond non woven + spun bond non woven+ spun bond non woven= four layer web hot rolled
SMS: spun bond non woven + melt blown fabric + spun bond non woven = three-layer web hot rolled
SMMS: spun bond non woven + melt blown fabric + melt blown fabric+ spun bond non woven = four layers of fiber web hot rolled.
