Vim yog kev txhim kho thev naus laus zis microbial, muaj ntau lub plastics uas puas tsuaj hauv ntiaj teb, ntawm cov uas muaj polylactic acid ntau dua thiab nrov dua. Txij li cov nroj tsuag polylactic acid yuav tsis siv cov peev txheej ib txwm muaj, cov tuam txhab tsim cov ntaub tsis-woven tau dhau los ua qhov xav paub ntau ntxiv hauv kev tsim cov khoom tshiab nrog cov khoom siv raw no. Ntau yam tsis-woven cov ntaub ua los ntawm polylactic acid yog biodegradable, thiab qee qhov sib xyaw polylactic acid nrog lwm yam ntuj tsim los yog rayon los ua cov khoom kawg biodegradable.

Polylactic acid membrane daim ntaub yog ib yam tshiab ntawm cov khoom siv raws li bio. Nws muaj qhov muag muag, muaj zog adsorption, noo noo, huab cua permeability thiab bacteriostasis. Nws yog cov khoom ntshiab, nyab xeeb, noj qab nyob zoo thiab kaw cov tawv nqaij. Nws muaj ntau yam yam ntxwv lom uas lwm cov substrates tsis tuaj yeem sib piv nrog. Nws yog cov txheej txheem zoo tshaj plaws rau lub ntsej muag lub ntsej muag zoo. Polylactic acid thiab nws cov polylactic acid fiber yog hu ua tib neeg' ntawm daim tawv nqaij thib ob vim yog lawv cov kab mob bacteriostasis ntuj, tiv thaiv kab mob thiab pH tus nqi ze rau ntawm daim tawv nqaij (SGS cov ntaub ntawv xeem). Polylactic acid tuaj yeem pab txhawb kev loj hlob ib txwm ntawm cov tawv nqaij ntawm tes. Nws tau siv los ua kab lis kev cai ntawm tes hauv cov tawv nqaij ua haujlwm engineering hauv kev kho mob （Lub tsev qiv ntawv dav dav ntawm kev tshaj tawm online ntawm Suav cov ntawv xov xwm kev kawm, qhov teeb meem 22, 2002)
Polylactic acid tuaj yeem cog rau hauv tib neeg lub cev thiab nqus los ntawm tib neeg lub cev. Nws tau siv hauv kev kho mob ze li 30 xyoo. Polylactic acid fiber ntau tuaj yeem siv los cais qee qhov dawb molecules los ntawm txheej txheej ntawm daim npog. Cov qauv me me muaj lub zog osmotic muaj zog. Thaum ua ke nrog cov tshuaj lactic acid ntawm daim tawv nqaij, nws tuaj yeem tsis tsuas yog txwv tsis pub cov kab mob, tab sis kuj txhim kho kev nqus ntawm cov khoom noj muaj txiaj ntsig thiab txhim kho qhov tseem ceeb ntawm daim tawv nqaij ntawm lub ntsej muag. Nyob rau tib lub sijhawm, polylactic acid membrane daim ntaub muaj qhov ua tau zoo nqus dej, tuaj yeem khaws cov ntsiab lus ntau ntxiv, thiab muaj kev ua kom muaj zog adsorption, tuaj yeem zoo dua nqus cov roj thiab tshem tawm cov tsis huv, yog li lub ntsej muag ntawm lub ntsej muag kom ua tiav qib huv. Cov qauv ntxeem tau ntawm daim ntaub polylactic acid tuaj yeem ua rau huab cua thiab dej ua kom dhau mus, khaws qhov ua haujlwm tseem ceeb hauv qhov tseem ceeb, khaws cov dej noo zoo, qhov tseem ceeb tsis yooj yim kom qhuav lossis hloov pauv, ua kom lub sijhawm nqus ntawm daim tawv nqaij, thiab tuaj yeem txhawb nqa cov khoom lag luam.
Tam sim no, tsuas muaj ob lub chaw tsim khoom ntawm polylactic acid non-woven fabrics hauv Nyij Pooj, shintec thiab unitika. Cov nplaum kub thiab xav tau cov ntaub tsis-woven ua los ntawm polylactic acid tau siv ntau dua. Hauv Suav teb, tsuas yog Ma' anshan tongjieliang lub tuam txhab tau tsim cov pawm, cov ntaub so huv, polylactic acid fiber ntau daim pam, thiab lwm yam yam tsis muaj cov khoom xyaw ntxiv, cov ntaub ntawv yog cov tshuaj tiv thaiv kab mob thiab mite.
