Polylactic acid (PLA) yog cov khoom siv biodegradable tshiab uas siv cov hmoov txhuv nplej siab uas tau muab rho tawm los ntawm cov khoom siv cog qoob loo (xws li pob kws).Starch raw khoom yog saccharified kom tau qabzib, nws fermented los ntawm qabzib thiab ib co hom los tsim lactic acid nrog siab purity, ces ib tug npaum li cas ntawm PLA yog synthesized los ntawm txoj kev ntawm tshuaj synthesis.Nws muaj biodegradability zoo, thiab tom qab siv uas tuaj yeem degraded tag nrho los ntawm cov kab mob hauv cov xwm txheej, nws thiaj li tsim cov pa roj carbon dioxide thiab dej, uas tsis ua phem rau ib puag ncig thiab muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig.Yog li peb txhua tus paub, PLA tau lees paub tias yog ib puag ncig. phooj ywg cov ntaub ntawv.
Nrog rau kev txhawb nqa thoob ntiaj teb ntawm kev txwv cov yas, PLA tau nce ntxiv rau ntau hom khoom yas, xws li cov hnab ntim khoom, cov thawv ntim khoom noj thiab cov hnab tsis-woven.
PLA nonwovens yuav ua tau 100% degradation nyob rau hauv lub ntuj puag ncig, thiab zoo applicability, tsis tsuas yog haum rau cov khoom siv xaws, tab sis kuj haum rau ultrasonic vuam tsis-woven hnab ua tshuab, tab sis vim hais tias ntawm lub peev xwm yog txwv, yog li tus nqi siab dua. PP non-woven, yog li kev lag luam kev lees paub tsis siab, tab sis ntseeg tias nrog kev txhim kho ntawm PLA ntau lawm tshuab thiab nthuav dav ntawm cov nplais, PLA yuav dhau los ua cov khoom siv tseem ceeb ntawm cov khoom ntim.
