Polylactic acid non-woven npuag cov ntaub ntawv tuaj yeem ua ke cov txiaj ntsig kev ua tau zoo ntawm polylactic acid nrog cov yam ntxwv ntawm ultrafine fibers, thaj chaw loj tshwj xeeb, thiab cov porosity siab ntawm cov ntaub ntawv tsis-woven, thiab muaj daim ntawv thov dav dav hauv kev pom huab cua.
Daim ntawv thov ntawmpolylactic acid tsis woven ntaubHauv kev lag luam huab cua lim tuaj yeem muab faib ua cov ntaub ntawv npog ntsej muag thiab cov ntaub ntawv lim dej ib puag ncig (kev lag luam pa luam yeeb thiab plua plav pom, huab cua huv, kev tiv thaiv tus kheej, thiab lwm yam).
Yog li, dab tsi yog qhov zoo thiab cov yam ntxwv ntawm kev siv polylactic acid non-woven npuag ua ib qhohuab cua lim khoom?
Biodegradability
Rau lub npog ntsej muag lim cov ntaub ntawv, biodegradability yog ib yam tseem ceeb heev. Lub npog ntsej muag lim txheej siv ob txheej txheej yaj tshuab PP tsis-woven npuag, uas yuav luag tsis muaj degradable. Cov qhov ncauj qhov ntswg tso tseg, txawm tias ntws mus rau hauv dej hiav txwv thiab dej hiav txwv lossis faus hauv av, ua rau muaj kev hem thawj loj rau ecosystem.
Lub npog ntsej muag lim txheej ua los ntawmCov khoom siv polylactic acidtuaj yeem tsis tsuas yog lim cov khoom tsis zoo xws li plua plav thiab cov kab mob hauv huab cua, tab sis kuj degrade tom qab siv thiab pov tseg, txo qhov siab ntawm ecosystem.
Thaum cov khoom lag luam polylactic acid raug cuam tshuam rau ib puag ncig ntuj nrog qee qhov kub thiab av noo (xws li xuab zeb, silt, dej hiav txwv), polylactic acid tuaj yeem decomposed rau hauv carbon dioxide thiab dej los ntawm cov kab mob. Yog hais tias polylactic acid fibers tau faus rau hauv av, lub sij hawm degradation ntawm ntuj yog li 2-3 xyoos; Yog hais tias polylactic acid fibers yog tov nrog organic pov tseg thiab faus, lawv yuav decompose nyob rau hauv ob peb lub hlis.
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 ℃, av noo 98%, thiab microbial tej yam kev mob) rau 3-6 lub hlis.
Antibacterial thiab deodorizing agents
Qhov tshwj xeeb ntawm polylactic acid fiber yog nyob rau hauv nws lub peev xwm tsis tau tsuas yog ua kom tiav "lub cev pom", tab sis kuj "biological filtration". Qhov saum npoo ntawm PLA fiber yog tsis muaj zog acidic, uas tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab txo qis kev sib kis ntawm cov kab mob thiab cov kab mob hauv huab cua rau qee yam. Nyob rau hauv cov nqe lus ntawm deodorization, nws tsuas yog tso siab rau nws tus kheej acidity los rhuav tshem cov qauv ntawm tes ntawm cov ntxhiab tsw ua rau cov kab mob, tua cov ntxhiab tsw ua rau cov kab mob, thiab ua tiav cov txiaj ntsig ntawm deodorization.
Raws li tus yam ntxwv no, polylactic acid pov tseg biodegradable lub qhov ncauj qhov ntswg muaj qhov cuam tshuam loj rau deodorizing thiab tuaj yeem hnav tau ntev yam tsis ua pa. Siv rau cov khoom siv lim cua hauv tsev, cov cua lim tau tshiab thiab tsis muaj ntxhiab, thaum tiv thaiv cov khoom siv lim los ntawm pwm thiab ua kom zoo, txuas ntxiv nws lub neej kev pab cuam.
Lim kev ua haujlwm
Polylactic acid fibers muaj qee yam kev lim dej, thiab lawv cov fiber ntau fineness thiab cross-sectional shape tuaj yeem tsim los ua kom zoo dua cov huab cua ntws thiab cov khoom ntim, zoo lim tawm cov khoom me me thiab cov pa phem hauv huab cua.
Siab breathability
Cov qauv tsim ntawm polylactic acid fibers tuaj yeem ua tiav siab ua pa, ua kom cov cua ntws zoo yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm huab cua ncig.
Zoo tensile zog
Polylactic acid fibers muaj lub zog tensile siab, uas ua rau huab cua lim paj rwb ntau ruaj thiab tsis tshua muaj deformation lossis puas thaum siv.
Lub zog thiab toughness
Nonwoven fabrics ua los ntawm polylactic acid fibers muaj peev xwm ua tau siab zog thiab zoo heev toughness kom tau raws li qhov yuav tsum tau folding ntawm tej daim ntawv thov scenarios. Nrog rau kev vam meej ntawm kev sib raug zoo txoj kev loj hlob thiab technological innovation nyob rau hauv lub textile kev lag luam, polylactic acid cov ntaub ntawv nrog richer functionality yuav muab cov neeg siv kev xaiv ntau.
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.
