Hauv kev lag luam ntim khoom, "tsawg-carbon" thiab "sustainability" tau maj mam dhau los ua kev txhawj xeeb tseem ceeb. Cov hom lag luam tseem ceeb tau pib txhim kho ecological friendliness ntawm lawv cov khoom kawg los ntawm ntau yam xws li tsim, tsim khoom, thiab xaiv cov khoom zoo ib puag ncig.
Tam sim no,Polylactic acid (PLA) cov ntaub ntawv tsis-wovennrog biodegradability zoo thiab kev ua haujlwm zoo tau dhau los ua cov khoom ntim tshiab. Tshwj xeeb, kev siv polylactic acid non-woven npuag raws li cov khoom ntim muaj cov yam ntxwv hauv qab no:
Ecological friendliness
Lub ecological friendliness ntawm polylactic acid fibers thiab non-woven fabrics yuav manifested nyob rau hauv peb yam: "bio raws, biodegradable, thiab yooj yim rau recycle".
Ntawm lawv, polylactic acid fiber ntau cov khoom tsis-woven npuag tuaj yeem ua tiav rau hauv cov pa roj carbon dioxide thiab dej los ntawm cov kab mob hauv ib puag ncig ntuj nrog qee qhov kub thiab av noo, xws li xuab zeb, silt, thiab dej hiav txwv. Polylactic acid cov khoom pov tseg tuaj yeem decomposed tag nrho rau hauv carbon dioxide thiab dej nyob rau hauv industrial composting tej yam kev mob (kub 58 ℃, vaum 98%, thiab microbial tej yam kev mob) rau 3-6 lub hlis; Landfilling nyob rau hauv cov pa ib puag ncig kuj tuaj yeem ua tiav degradation hauv 3-5 xyoos.
Nws yuav tsum tau muab sau tseg tias kev lag luam composting ntawm polylactic acid yuav tsum tau tej yam kev mob kom ua tiav. Raws li cov khoom ntim, polylactic acid non-woven npuag cov khoom muaj lub neej voj voog thiab kev ua haujlwm zoo hauv cov pa ib puag ncig. Txawm hais tias nyob hauv ntau qhov chaw thauj mus los xws li av, tsheb ciav hlau, hiav txwv, thiab huab cua, lawv tuaj yeem muab kev tiv thaiv ruaj khov rau cov khoom ntim khoom.
Zoo mechanical kev ua tau zoo
Polylactic acid non-woven npuagmuaj cov khoom siv zoo, nrog rau qee lub zog thiab tsim kua muag zoo, thiab tuaj yeem tiv taus qee qhov siab thiab cuam tshuam. Hauv kev siv tswv yim, nws tuaj yeem muab kev tiv thaiv cushioning rau cov khoom ntim khoom.
Mos thiab khawb resistant
Polylactic acid fibers thiab non-woven fabrics kuj muaj kev hloov tau zoo, uas tuaj yeem muab kev tiv thaiv zoo rau cov khoom ntim hauv daim ntawv thov ntim, tsis muaj kev puas tsuaj rau cov xim pleev xim thiab cov tsos, thiab tsis cuam tshuam rau kev muag khoom thiab cov neeg siv khoom.
Texture tsis shedding chips
Polylactic acid non-woven npuag ntim muaj kev ntxhib los mos zoo, tsis plam chips, tuaj yeem tswj tau qhov zoo nkauj ntawm cov khoom, thiab tsis cuam tshuam rau kev muag khoom.
Tsis muaj thiab poob siab absorbing
Polylactic acid fiber tsis tsuas yog siv rau cov khoom ntim, tab sis kuj ua rau hauv PLA flakes, ntxiv kev muab cushioning thiab shock absorbing tiv thaiv rau cov khoom.
Cov ntaub ntawv ntuj tuaj yeem siv rau ntim khoom noj
Cov khoom siv raw ntawm polylactic acid fiber ntau yog los ntawm cov nroj tsuag txuas ntxiv dua tshiab xws li pob kws, qos yaj ywm, thiab qoob loo straw. Nws muaj biocompatibility zoo, biodegradability, antibacterial zog, thiab breathability. Nws tuaj yeem siv dav hauv kev ntim khoom ntawm ntau yam khoom noj, tshuaj, thiab cov khoom tshiab, xws li kev khaws txiv hmab txiv ntoo, hnab tshuaj yej, hnab kas fes, thiab kev tsim khoom ntawm lwm cov khoom ntim khoom lom.
Tshem tawm tam sim ntawd thaum tawm hauv hluav taws, txo cov pa taws thiab tsis muaj tshuaj lom
Polylactic acid fiber yog tsis yooj yim rau hlawv, tua tam sim ntawd thaum ignition, tsis muaj pa taws dub los yog toxic gas emissions, thiab muaj kev nyab xeeb zoo hauv kev siv.
Kev siv dav dav
PLA fiber txhawb kev sib xyaw nrog lwm cov cellulose fibers (xws li xyoob fiber ntau, viscose fiber, thiab lwm yam), uas tuaj yeem tsis tsuas yog txo cov nqi thaum tuav tag nrho cov degradability ntawm cov khoom ntim, tab sis kuj ua tiav kev nplua nuj ntawm cov khoom ntim thiab ua tau raws li qhov xav tau ntawm daim ntawv thov scenarios.
Tsis tas li ntawd, polylactic acid fibers muaj zog yoog raws thiab tuaj yeem hloov kho raws li cov neeg siv khoom xav tau, tsim nyog rau ntim cov khoom ntawm ntau yam duab thiab ntau thiab tsawg.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
