Polylactic Acid (PLA), bio-raws li biodegradable polymer muab tau los ntawm cov khoom siv cog dua tshiab xws li pob kws thiab qab zib, tab tom ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntsuab ntawm cov khoom siv tu cev ntawm poj niam-tshwj xeeb hauv cov ntaub so ntswg, panty liner, thiab lwm yam khoom. Nws cov txiaj ntsig tseem ceeb nyob hauv kev txo qis ib puag ncig cuam tshuam tom qab pov tseg thaum ua kom cov neeg siv kev nyab xeeb thiab kev nplij siab.
Qhov zoo ntawm qhov tseem ceeb ntawmSterilizable PLA GranulesNyob rau hauv feminine huv daim ntaub ntawv muaj xws li compostability nyob rau hauv industrial tej yam kev mob (58-70 degree, high humidity, active microorganisms), nrog ua tiav degradation rau CO₂, H₂O, thiab organic teeb meem nyob rau hauv 90-180 hnub. Cov khoom muaj kev sib raug zoo ntawm daim tawv nqaij zoo nrog pH qib ze rau nruab nrab lossis me ntsis acidic (kwv yees li 5.5-6.5), sib piv cov tawv nqaij noj qab haus huv. Nws tsis muaj qhov ua kom khaus, tsis tas yuav muaj cov kuab tshuaj thaum lub sijhawm tsim khoom, thiab tsis muaj cov khoom phom sij xws li formaldehyde thiab optical brighteners. Nrog rau kev ua xua tsis tshua muaj ntawv pov thawj los ntawm ISO 10993-5/-10 rau cytotoxicity thiab kev ntsuam xyuas ntawm daim tawv nqaij, nws muab qhov chaw qhuav, tsis nplaum uas ua rau cov neeg siv kev nplij siab. Cov lactic acid uas ua rau lub sijhawm degradation inhibits kev loj hlob ntawm qee cov kab mob, pab txo cov ntxhiab tsw.
Sterilizable PLA GranulesUa kom pom kev ua tau zoo sib xws, hloov tau rau cov kab uas twb muaj lawm uas tsis yog - woven ntau lawm xws li kub- huab cua, spunbond, thiab hydroentanglement technologies, yuav tsum tau hloov me me kub (PLA ua kub: 180-230℃). Txawm hais tias tseem muaj chaw rau kev txhim kho cov nqi siv nyiaj thiab lub zog ntub dej,Sterilizable PLA Granulestau dhau los ua cov ntaub ntawv tseem ceeb rau hwm eco- cov ntaub so ntswg huv, sawv cev rau kev lag luam hloov pauv los ntawm kev yooj yim mus rau ob qho txiaj ntsig ntawm kev noj qab haus huv ntawm tus kheej thiab kev phooj ywg hauv ntiaj teb. Lawv sib raug zoo nrog ntau yam kev ua kom tsis muaj menyuam thiab ntawv pov thawj raws li cov qauv kev nyab xeeb thoob ntiaj teb ua rau lawv lub luag haujlwm xaiv rau cov hom lag luam cog lus los ua ke kev ua tau zoo, kev nyab xeeb, thiab kev saib xyuas ib puag ncig hauv cov khoom tu poj niam.
