Nws yog cov khoom sib xyaw ntawm spunbond thiab meltblown, tsis muaj tshuaj lom thiab tsis muaj ntxhiab, nrog kev ua haujlwm siab ntawm cov kab mob cais tawm.Los ntawm kev kho tshwj xeeb ntawm cov cuab yeej siv, nws tuaj yeem ua tiav qhov kev ua tau zoo ntawm kev tiv thaiv zoo li qub, tiv thaiv dej cawv, tshuaj tiv thaiv ntshav, dej tiv thaiv thiab dej ntau lawm.
SMS ntau lawm txheej txheem
Ntxiv 3% -7% ntawm masterbatch hauvSMS nonwoven spinning ntau lawm;Kev npaj cov khoom siv ua haujlwm: Cov khoom siv ua haujlwm muaj xws li cov tshuaj tiv thaiv dej, nplaim hluav taws, tshuaj tiv thaiv kab mob, tus neeg saib xyuas nkag thiab dej sib tov;smS nonwoven yog impregnated nyob rau hauv lub impregnation da dej nrog functional auxiliaries, dov qhuav, qhuav thiab txias kom tau raws li yuav tsum tau multifunctional SMS nonwoven.
Cov txheej txheem tseem ceeb rau kev tsim SMS nonwovens yog "ib-kauj ruam", "ob-kauj ruam" thiab "ib-thiab-ib-ib-kauj ruam" txoj kev.
SMS khoom ua haujlwm
Tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab muaj txiaj ntsig zoo hauv kev cais cov kab mob.Los ntawm kev kho tshwj xeeb ntawm cov cuab yeej siv, nws tuaj yeem ua tiav qhov kev ua tau zoo ntawm kev tiv thaiv zoo li qub, tiv thaiv dej cawv, tshuaj tiv thaiv ntshav, dej tiv thaiv thiab dej ntau lawm.

1. Lub teeb yuag: ua los ntawm polypropylene resin, lub ntiajteb txawj nqus tsuas yog 0.9, tsuas yog peb feem tsib ntawm paj rwb, nrog fluffiness thiab zoo handfeel.
2. Mos: Ua los ntawm cov fibers zoo (2-3D), nws maj mam sib txuas nrog kub yaj.Cov khoom tiav yog mos mos thiab muaj kev xav zoo.
3. Cov tshuaj tiv thaiv dej thiab ua pa: Polypropylene slices tsis nqus dej, thiab cov ntsiab lus dej yog xoom, yog li cov khoom tiav muaj dej zoo.
4. Tsis muaj tshuaj lom thiab tsis ua rau khaus: Cov khoom yog tsim los ntawm FDA cov khoom noj khoom haus qib raw khoom thiab tsis muaj lwm cov khoom xyaw tshuaj, nrog rau kev ua haujlwm ruaj khov, tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis ua rau tawv nqaij.
5. Kev tiv thaiv kab mob, tshuaj tiv thaiv: Polypropylene yog cov tshuaj chemically blunt, tsis yog kab, thiab tuaj yeem cais cov kab mob thiab kab hauv cov kua dej yaig;anti-bacteria, alkali corrosion, cov khoom tiav tsis cuam tshuam lub zog vim kev yaig.
6. Cov khoom zoo ntawm lub cev: spun polypropylene yarn ncaj qha mus rau hauv lub network ntawm kev sib txuas ntawm cov khoom kub, lub zog ntawm cov khoom yog zoo dua li cov khoom siv fiber ntau, lub zog tsis yog kev taw qhia, ntev thiab kab rov tav lub zog zoo ib yam.
