Hauv thaj chaw textile, polyvinyl alcohol (PVA) tau qhia tias nws coj los ua txoj kev hloov pauv uas ntxiv cov haujlwm thiab cov yam ntxwv zoo nkauj rau cov ntaub. Tsab xov xwm no saib xyuas txog PVA, qhov chaw thiab cov txiaj ntsig hauv cov ntawv textile, cov txheej txheem tsim khoom, kev ruaj khov thiab kev txhim kho ntawm kev ua haujlwm.
Cov lag luam textile tsis nyob ib qho li, vim cov kev daws teeb meem textile automated nrhiav cov khoom tshiab uas tuaj yeem ua tiav cov requirments ntawm khw thiab kev tiv thaiv ib puag ncig. Cov polymer synthetic soluble hauv dej uas paub tias yog PVA yog tsis muaj tshuaj lom thiab biodegradable ua rau nws yog ib qho kev xaiv txaus siab rau kev siv hauv cov lag luam textile ntau dua li cov kev xaiv uas muaj kev phom sij ntau. Vim nws cov yam ntxwv soluble hauv dej, nws tuaj yeem yooj yim siv thiab yooj yim ntxuav tawm, yog li ntawd muab cov chaw tsim khoom ib qho kev xaiv yooj yim rau cov ntaub.
PVA yog feem ntau siv hauv cov ntaub ntawv rau kev txhim kho thiab tsim cov ntaub tsis muaj ntaub. Feem ntau siv hauv cov khoom noj huv, kev kho mob thiab kev lag luam, cov ntaub no pom tau siv dav. PVA muaj peev xwm ua kom tau raws li cov kev xav tau ntawm cov ntaub tsis muaj ntaub uas ruaj khov vim nws qhov kev muaj peev xwm txuas cov fiber zoo. PVA kuj tseem muaj txiaj ntsig hauv kev nce qib ntawm cov peev xwm nqus dej ntawm cov ntaub thiab softness uas tsim nyog hauv cov ntawv thov uas muaj kev ua haujlwm thiab kev nplij siab yog qhov tseem ceeb.
Tsis tas li ntawm cov ntaub tsis muaj ntaub, PVA kuj tseem siv tau hauv cov txheej txheem textile thiab cov khoom tiav. Nws kuj tseem muaj peev xwm tau txais cov ntaub uas tuaj yeem raug xim lossis suav tias yog dej tsis nkag nrog kev pab ntawm nws lub peev xwm tsim cov yeeb. Nrog PVA txheej, cov chaw tsim khoom fiber tuaj yeem tsim cov ntaub uas tsis tsuas yog dej tsis nkag tab sis kuj tsis muaj av, ua rau lawv muaj zog dua thiab txo nqi tu kom ntev. Qhov no yog tsim nyog hauv cov khaub ncaws sab nraum zoov thiab cov khaub ncaws ua haujlwm, uas yog, qhov chaw cov ntaub yuav tsum muaj zog thiab tiv thaiv huab cua.
Cov nyom ntawm textile industry yog loj heev, ua rau sustainability yog ib qho teeb meem tseem ceeb: PVA muab ib qho kev pom zoo hauv qhov no. Vim muaj kev paub ntau ntxiv txog hom khoom uas lawv yuav, cov neeg siv khoom ua rau cov hom ntawv siv cov khoom uas yog ib puag ncig zoo. Vim PVA yog biodegradable, cov khoom textile uas muaj cov polymer zoo li no muaj peev xwm raug biologically degraded uas pab daws qhov teeb meem pov tseg thiab txhawb nqa ib qho kev lag luam circular. Nws tsis xaus ntawm ntawd, PVA kuj tseem tuaj yeem tsim los ntawm cov khoom bio-based uas qhia txog ntau yam green credentials.
PVA qhov muaj ntau yam yog kuj txuas nrog nws qhov kev siv hauv dyeing thiab luam ntawv property. Cov txheej txheem niaj hnub rau dyeing feem ntau muaj kev siv tshuaj thiab toxins uas tej zaum yuav muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv. PVA, hauv qhov no, tuaj yeem siv tau ua tus nqa rau dyes thiab yog li ntawd pab txhawb kom tsim kho cov txheej txheem dyeing uas zoo dua. Qhov no tsis tsuas yog txo qis dej thiab hluav taws xob uas siv hauv txoj haujlwm tab sis kuj txo qis cov pa phem uas tawm mus rau ib puag ncig.
Saib rau pem, nws yog qhov xav tau tias yuav muaj lwm yam tshiab hauv kev ua haujlwm vim yog kev siv cov khoom tshiab xws li PVA. Qhov laj thawj rau cov kev xav no tuaj ntawm qhov paub txog kev txhim kho thev naus laus zis thiab kev nce qib ntawm kev saib xyuas txog cov teeb meem ib puag ncig - nws yog qhov xav tias, cov peev txheej rau kev siv PVA hauv textile production yuav nce. Cov kev txhim kho hauv kev lag luam feem ntau qhia txog qhov kev txav no thiab, vim ntau thiab ntau lub tuam txhab tab tom hloov mus rau cov khoom siv biopolymer matrix hom es tsis yog cov khoom siv qub. Yog li, PVA yuav muaj feem yuav dhau los ua ib qho ntawm cov khoom tseem ceeb ntawm cov textile tshiab tiam uas tso cai rau kev tsim kho cov kev pom zoo hauv kev lag luam hauv txoj kev tiv thaiv ib puag ncig.
