Nonwovens tau dhau los ua ib qho tseem ceeb ntawm ntau yam kev lag luam vim lawv cov khoom tshwj xeeb thiab ntau yam. Saib ua ntej mus rau tsib xyoos tom ntej no, kev lag luam nonwovens kev lag luam yuav pom kev loj hlob tseem ceeb uas tau tsav los ntawm kev txhim kho thev naus laus zis, kev xav tau ntau ntxiv hauv ntau qhov chaw thov thiab kev tsom mus rau kev ruaj khov.
Nonwoven fabricsyog cov khoom siv hluav taws xob ua los ntawm cov fibers sib txuas ua ke los ntawm kev siv tshuab, thermal lossis cov txheej txheem tshuaj. Tsis zoo li cov tsoos woven fabrics, nonwoven fabrics tsis xav tau weaving los yog knitting, uas tso cai rau kom sai ntau lawm thiab ntau dua tsim yooj. Qhov no feature ua rau nws tshwj xeeb tshaj yog txaus nyiam nyob rau hauv industrial daim ntaub ntawv uas efficiency thiab kev ua tau zoo tseem ceeb heev.
Ib qho ntawm cov tsav tsheb tseem ceeb ntawm kev loj hlob ntawm kev lag luam nonwovens kev lag luam yog qhov kev thov loj hlob los ntawm kev lag luam tsheb. Nonwovens yog siv nyob rau hauv ntau yam kev siv tsheb, xws li thermal rwb thaiv tsev, suab rwb thaiv tsev, thiab pom. Raws li kev lag luam tsheb txuas ntxiv mus ntxiv, tshwj xeeb tshaj yog nrog kev nce ntawm cov tsheb hluav taws xob, qhov kev thov rau lub teeb yuag, ruaj khov, thiab cov khoom siv tau zoo yuav loj tuaj. Nonwovens muab cov kev daws teeb meem zoo tshaj plaws, nrog cov khoom tsim nyog los txhim kho kev ua haujlwm ntawm lub tsheb thaum txo qhov hnyav tag nrho ntawm lub tsheb.
Ntxiv nrog rau kev lag luam tsheb, kev lag luam kev noj qab haus huv yog lwm qhov tseem ceeb rau kev loj hlob ntawm kev lag luam nonwovens. Kev kis tus kab mob COVID-19 tau hais txog qhov tseem ceeb ntawm kev nyiam huv thiab kev nyab xeeb, ua rau muaj kev xav tau ntawm cov khoom siv kho mob tsis zoo xws li lub qhov ncauj qhov ntswg, khaub ncaws tiv thaiv, thiab cov ntaub qhwv phais. Raws li lub ntiaj teb kev noj qab haus huv cov txheej txheem txuas ntxiv tseem ceeb rau kev tswj hwm tus kab mob thiab kev nyab xeeb ntawm tus neeg mob, kev cia siab rau cov khoom siv tsis yog yuav tsum muaj zog. Tsis tas li ntawd, kev tsim kho tshiab hauv kev kho mob antimicrobial thiab cov ntaub ntawv biodegradable zoo li yuav txhim kho qhov kev thov ntawm nonwovens hauv cov haujlwm no.
Kev tsim kho kev lag luam kuj tseem maj mam lees paub qhov zoo ntawm nonwovens. Vim lawv cov kav ntev thiab ua haujlwm rau ib puag ncig kev cuam tshuam, cov ntaub ntawv no tau siv ntau dua hauv geotextiles, rwb thaiv tsev cov ntaub ntawv thiab cov ntaub ntawv vov tsev. Nrog rau kev nrawm ntawm nroog loj thiab nthuav dav ntawm cov phiaj xwm kev tsim kho vaj tsev, qhov kev thov rau cov khoom siv tsis zoo hauv kev tsim kho kev lag luam yuav tsum loj hlob loj hauv tsib xyoos tom ntej.
Sustainability yog lwm qhov tseem ceeb uas yuav cuam tshuam rau yav tom ntej ntawm kev lag luam nonwovens. Raws li kev paub txog ib puag ncig txuas ntxiv zuj zus, cov tuam txhab lag luam tau tsom mus rau kev tsim cov khoom tsis zoo ib puag ncig. Qhov no suav nrog kev siv cov fibers rov ua dua tshiab, biodegradable polymers, thiab siv cov txheej txheem tsim khoom ruaj khov. Raws li cov neeg siv khoom thiab cov lag luam ib yam li qhov tseem ceeb ntawm kev ruaj khov, kev thov rau cov khoom siv tsis yog cov khoom siv uas ua raws li cov txiaj ntsig no yuav tsum nce ntxiv.
Kev txhim kho thev naus laus zis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim lub neej yav tom ntej ntawm kev lag luam nonwovens. Kev tsim kho tshiab hauv kev siv tshuab fiber ntau, kev sib koom ua ke, thiab cov txheej txheem ua tiav yog ua rau cov tuam txhab tsim cov khoom siv tsis zoo nrog cov khoom zoo dua qub, xws li kev ua kom muaj zog, softness, thiab kev tswj cov dej noo. Cov kev nce qib no yuav tsis tsuas yog nthuav dav ntau yam ntawm cov ntawv thov rau nonwovens, tab sis tseem yuav txhim kho lawv cov kev ua tau zoo hauv kev siv uas twb muaj lawm.
Txhua yam nyob rau hauv tag nrho, qhov kev pom rau kev lag luam nonwovens lag luam yog ci nyob rau tsib xyoos tom ntej. Nrog rau kev thov loj hlob los ntawm kev lag luam tsheb, kev kho mob thiab kev tsim kho, nrog rau kev tsom mus rau kev ruaj khov thiab thev naus laus zis tshiab, cov khoom siv tsis yog qhov chaw zoo los ua kom tau raws li cov kev xav tau ntawm ntau yam kev lag luam. Raws li cov chaw tsim khoom txuas ntxiv tshawb nrhiav cov ntawv thov tshiab thiab txhim kho txoj hauv kev tsim khoom, kev loj hlob muaj peev xwm hauv cheeb tsam no loj heev, ua rau thaj chaw tsim nyog saib hauv xyoo tom ntej.
