SMS, ib cov ntaub ntawv tsis sib thooj. Nws tau tsim los ntawm lub tuam txhab American, pib siv cov ntaub ntawv kho mob, cov ntaub ntawv pom zoo thiab lwm yam.
Cov ntawv xov xwm ntawm SMS tsis sib xws ntawm Mesh nonwovens (S) thiab cua daj cua dub nonwovens (M) yog thawj tsim los ntawm ib lub tuam txhab Asmeskas ntau tshaj 20 xyoo dhau los, thiab tom qab ntawd lawv tau ua tiav hauv daim ntawv thov cov ntaub ntawv huv thiab cov ntaub ntawv lim. Qhov khaus nyias qhov sib tw ua cov khoom tsis yog khoom siv tau zoo, tab sis nws qhov loj loj yog loj thiab nws cov permeability yog pluag. Txawm li cas los xij, qhov pom thiab shielding cov khoom ntawm cov ntaub ntawv tsis muaj ntaub thaiv nrog ultrafine fibers yog zoo heev, tab sis lub zog tensile ntawm cov ntaub ntawv tsis yog cov uas tsis muaj vim lawv cov kev kho mob tshwj xeeb. Yog li ntawd, ua ke ntawm blown tshuab thiab spunbonded tshuab ua SMS composites. Cov ntaub ntawv SMS yog siv rau cov khoom siv phais mob phais thiab cov khoom siv ua ntaub ntawv txhua qhov chaw. Hauv nruab nrab, cov ntaub ntawv tsis muaj ntaub thaiv zoo tuaj yeem tiv thaiv kom txhob nkag mus rau ntawm cov ntshav, lub cev kua, haus dej cawv thiab kab mob, thiab cov qauv ntawm cov nplua nuj fiber ntau tuaj yeem ua kom pom tseeb ntawm cov hws. Cov polypropylene spunbonded non non woven cov ntaub ntawv nyob rau hauv qaum thiab sab hauv txheej muaj zog thiab hnav tsis kam, thiab cov qauv ntaub thaiv kom qhov tsim cov tsis muaj fiber ntau, uas yog rau thaj chaw huv uas xav tau los ntawm kev ua haujlwm phais.
