Polylactic asidhi (PLA) chinhu chitsva chinogona kuparara chinoshandisa sitachi mbishi zvinhu izvo zvinotorwa kubva kune zvinogonekazve chirimwa zviwanikwa (sechibage).Starch raw material inosaccharified kuti iwane shuga, inoviriswa neglucose uye mamwe madhiri kuburitsa lactic acid nekuchena kwakanyanya, ipapo imwe chiyero chePLA inogadzirwa nenzira yemakemikari synthesis.Iine biodegradability yakanaka, uye mushure mekushandisa iyo inogona kuderedzwa zvachose nehutachiona hwechisikigo, pakupedzisira ichigadzira kabhoni dhaikisadhi nemvura, iyo isingasvibise zvakatipoteredza uye inobatsira zvikuru kuchengetedzwa kwezvakatipoteredza.Saka sezvatinoziva tese，PLA inozivikanwa seyakatipoteredza. zvinhu zvine ushamwari.
Nekusimudzirwa kwepasi rose kwezvirambidzo zvepurasitiki, PLA iri kuwedzera kushandiswa mumhando dzakasiyana dzezvigadzirwa zvepurasitiki, senge mabhegi ekurongedza, mabhokisi ehupfu anoraswa uye mabhegi asina kurukwa.
PLA nonwovens inogona kuve 100% degradation munzvimbo yechisikigo, uye kushanda zvakanaka, kwete yakakodzera chete yekusona yekugadzira, asiwo yakakodzera kune ultrasonic welding isiri-yakarukwa yekugadzira bhegi muchina, asi nekuda kwehukwanisi hushoma, saka mutengo wakakwira kupfuura. PP isiri-yakarukwa, saka kugamuchirwa kwemusika hakuna kukwira, asi tenda kuti nekuvandudzwa kwePLA tekinoroji yekugadzira uye nekuwedzera kwechiyero chekugadzira, iyo PLA ichava iyo huru yezvigadzirwa zvekurongedza.
