Hauv kev kho mob tsis-woven cov ntaub, feem ntau siv cov khoom siv polymer yog PP, uas yog, polypropylene yog siv los ua cov khoom siv raw rau cov kiv mus rau hauv cov ntaub tsis-woven. Txij li thaum PP tsis muaj cov pab pawg hydrophilic, nws yog ib qho tsim nyog yuav tsum tau txau cov kab mob tsawg heev ntawm 0.5% lossis tsawg dua nyob rau saum npoo ntawm tsis-ntaub npuag. Tus sawv cev roj dej.
S denotes spunbond, Suav txhais cov lus rau spunbond nonwoven; M sawv cev rau Meltblown, Suav cov lus txhais rau hauv meltblown nonwoven. Hauv cov txheej txheem tsis-woven cov txheej txheem, muaj txheej txheem sandwich qauv cov ntaub ntawv hu ua SMS, uas yog tus qauv spunbond-meltblown-spunbond. Cov khoom no ua ke qhov zoo ntawm muaj zog spunbond npuag thiab zoo barrier khoom ntawm meltblown ntaub. Cov ntaub ntawv kho mob. Cov tsiaj ntawv luv uas koj hais tsis yog feem ntau.
SMP, Kuv xav tias nws yog spunbond meltblown composite, siv cov khoom PP.
SM, yog ib txoj kev spunmelt (Spunmelt)
SSPP yog spunbond-spunbond, ua los ntawm cov khoom siv PP. Feem ntau SS yog ob-txheej qhov sawv cev spunbond.
