Polylactic acid (PLA) non-woven npuag, tseem hu ua PLA non-woven npuag, yog 100 feem pua biodegradable non-woven fabric. 100 feem pua ntawm cov xwm txheej, 100 feem pua ntawm biodegradable, ib puag ncig tus phooj ywg, muaj zog txhua yam, tsis muaj tshuaj lom, tshuaj tua kab mob, ua pa, dav siv hauv kev tiv thaiv lub ntsej muag, huab cua pom thiab lwm yam.
Raws li kev sib txawv ntawm kev tsim cov ntaub tsis-woven, muaj ob hom PLA non-woven fabrics: PLA spunbond thiab PLA meltblown. Nws yog nyiam los ntawm ntau thiab ntau tus neeg.
PLA ntaub yog ib puag ncig tus phooj ywg thiab tsis muaj kuab paug rau lub ntiaj teb. Thaum spunbond thiab meltblown nonwovens tsis yog. PLA non-woven npuag muaj qhov zoo tshaj plaws biodegradability, antibacterial, nplaim retardant thiab tsis-allergic. Nws yog tsim los ntawm lub tshuab tsis-woven. Nws yog ib qho ntawm cov khoom siv zoo tshaj plaws rau kev ua cov hnab tshuaj yej, kas fes pads, cov ntaub so ntswg, cov ris tsho kho mob thiab cov khoom siv tu cev.
PLA nonwoven yog dab tsi?
PLA yog qhov txawv ntawm PP thiab PET. Cov khoom siv raw ntawm PLA tsis-woven npuag yog polylactic acid. Nws yog muab rho tawm los ntawm pob kws, nplej, cassava, thiab lwm yam nroj tsuag. PLA biodegrades sai heev. Nws feem ntau yuav siv sijhawm 45 hnub kom ua tiav rau hauv CO2 thiab H2O.
