Textile fabric post finishing yog ib txoj kev kho mob uas ua rau cov nyhuv xim, cov nyhuv morphological (nqus, suede, starching, thiab lwm yam) thiab cov txiaj ntsig zoo (impermeable, non-felting, non-ironing, non-moth, nplaim taws, thiab lwm yam) mus rau ntaub.Kev ua tiav tom qab yog txheej txheem uas txhim kho qhov tsos thiab kev xav ntawm cov ntaub thiab txhim kho kev hnavuas yog ib qho tseem ceeb rau kev tsim cov khoom muaj nqis ntxiv thiab nce lub Hoobkaskev sib tw.
Yog li cia peb xam seb lawv yog dab tsi thiab lawv tuaj yeem paub.Peb nyob ntawd rau koj ua tiav kev daws teeb meem textile project.Thov koj xav tiv tauj peb.
Stentering xov yog txheej txheem uas ua rau kev siv cov plasticity ntawm cellulose, txhob lo lo ntxhuav, ntaub plaub thiab lwm yam fibers nyob rau hauv ntub tej yam kev mob, maj mam nthuav dav ntawm cov ntaub mus rau qhov luaj li cas thiab qhuav nws, nyob rau tib lub sij hawm stabilize cov ntaub qhov ntev.Hauv qee cov txheej txheem xws li scouring thiab bleaching, luam ntawv thiab dyeing ua ntej ua tiav, cov ntaub yog feem ntau muaj kev sib zog sib zog, uas ua rau cov ntaub kom ncab rau hauv cov kev taw qhia warp thiab shrink nyob rau hauv weft kev taw qhia, thiab tshwm sim lwm yam shortcomings, xws li qhov dav tsis sib xws. , cov npoo tsis sib luag, kev xav ntxhib, thiab lwm yam Txhawm rau ua kom cov ntaub muaj qhov sib xws thiab ruaj khov dav, thiab txhim kho cov kev tsis txaus siab saum toj no thiab txo cov deformation ntawm cov ntaub hauv cov txheej txheem hnav, tom qab dyeing thiab tiav cov txheej txheem ua tiav, cov ntaub yuav tsum tau stentered.
Thov xyuas lub tshuab stener tshiab tshaj plaws, kom paub meej ntxiv.
2. Ua ntej-Shrinking
Preshrinking yog txheej txheem ntawm kev txo cov shrinkage ntawm fabrics tom qab raus hauv dej los ntawm lub cev txoj kev.Nyob rau hauv tus txheej txheem ntawm weaving, dyeing thiab xov, cov ntaub yog tensioned nyob rau hauv warp kev taw qhia, thiab buckling yoj qhov siab nyob rau hauv lub warp kev taw qhia yog txo, yog li elongation yuav tshwm sim.Thaum cov ntaub ntawv hydrophilic fiber ntau saturated nrog dej, fiber ntau swells, thiab txoj kab uas hla ntawm warp thiab weft yarns nce, uas tsub kom lub warp buckling yoj qhov siab, shortens qhov ntev ntawm cov ntaub, thiab cov ntaub ntawv shrinkage.Thaum cov ntaub qhuav, qhov o ploj mus, tab sis kev sib txhuam ntawm cov xov paj tseem ua rau cov ntaub nyob rau hauv ib qho kev cog lus.Mechanical preshrinking yog txau cov pa los yog tshuaj tsuag kom ntub cov ntaub ua ntej, ces thov
mechanical extrusion nyob rau hauv warp kev taw qhia kom nce buckling yoj qhov siab, thiab ces xoob qhuav ntaub.Lub shrinkage ntawm pre shrunk paj rwb ntaub yuav raug txo kom tsawg tshaj li 1%, thiab cov softness ntawm cov ntaub yuav zoo dua vim yog kev sib nrig sib extrusion thiab rubbing ntawm fibers thiab yarns.Cov ntaub plaub tuaj yeem ua ntej shrunk los ntawm kev so.Tom qab dipped thiab dov nyob rau hauv dej sov los yog sprayed nrog chav, cov ntaub yog qhuav maj mam nyob rau hauv ib tug so, kom cov ntaub shrinks nyob rau hauv ob qho tib si warp thiab weft cov lus qhia.Npuag shrinkage kuj muaj feem xyuam rau nws cov qauv.Cov qib shrinkage ntawm fabrics feem ntau yog ntsuas los ntawm shrinkagetus nqi.
3 .Txhob-siab
Cov txheej txheem ntawm kev hloov cov khoom qub thiab cov qauv ntawm cov fiber ntau, txhim kho nws cov resilience, thiab ua rau cov ntaub nyuaj rau crease nyob rau hauv hnav yog hu ua crease resisting xov.Nws yog tsuas yog siv rau cov ntshiab los yog blended fabrics ntawm cellulose fibers, thiab kuj yuav siv tau rau txhob lo lo ntxhuav fabrics.Tom qab crease resistant finishing, lub rov qab cov cuab yeej ntawm cov ntaub ntawv nce, thiab ib co zog zog thiab hnav cov khoom yog zoo dua.Piv txwv li, lub crease kuj thiab seem stability ntawm paj rwb fabrics tau zoo heev, thiab lub peev xwm ntxuav thiab ziab kom qhuav kev ua tau zoo kuj tseem tuaj yeem txhim kho.Txawm hais tias lub zog thiab hnav tsis kam yuav poob mus rau qhov sib txawv, nyob rau hauv kev tswj ntawm cov txheej txheem ib txwm muaj, nws qhov kev hnav khaub ncaws yuav tsis cuam tshuam.Ntxiv nrog rau qhov crease kuj, lub zog tawg ntawm viscose npuag kuj nce me ntsis, tshwj xeeb tshaj yog lub zog ntub dej.Txawm li cas los xij, crease resistant finishing muaj qee yam cuam tshuam rau lwm yam khoom muaj feem xyuam, xws li tawg elongation ntawm cov ntaub txo qis mus rau qhov sib txawv, qhov kev ntxhua khaub ncaws nws txawv nrog tus neeg ua hauj lwm tiav, thiab kev ntxuav ceev ceev ntawm cov khoom dyed txhim kho, tab sis qee cov khoom tiav yuav txo tau. lub teeb ceev ceev ntawm qee cov dyes.
4. Kev teeb tsa cua sov,
Thermosetting yog cov txheej txheem rau kev ua cov thermoplastic fibers thiab lawv cov khoom sib xyaw lossis cov ntaub ntawv sib txuas kuj ruaj khov.Nws yog tsuas yog siv rau kev ua cov hluavtaws fibers thiab lawv cov khoom sib xyaw, xws li nylon lossis polyester, uas yooj yim rau shrink thiab deform tom qab cua sov.Thermoplastic fibers yuav tsim kev ntxhov siab nyob rau hauv cov txheej txheem textile, thiab nws yuav ua rau wrinkle thiab deformation nyob rau hauv qhov kev txiav txim ntawm ya raws, tshav kub thiab sab nraud quab yuam nyob rau hauv dyeing thiab xov.Yog li ntawd, nyob rau hauv ntau lawm (tshwj xeeb tshaj yog nyob rau hauv ntub cua sov ua xws li dyeing los yog luam ntawv), feem ntau, cov ntaub yog kho ntawm ib tug me ntsis siab kub tshaj li cov txheej txheem tom ntej nyob rau hauv nro, uas yog, tshav kub kub, thiaj li tiv thaiv shrinkage thiab deformation ntawm lub ntaub thiab pab txhawb cov txheej txheem tom ntej.Tsis tas li ntawd, cov xov paj elastic (filament), cov xov paj uas tsis tshua muaj siab (filament) thiab cov xov paj loj kuj tuaj yeem tsim los ntawm cov txheej txheem cua sov ua ke nrog rau lwm yam kev siv lub cev lossis cov khoom siv.
Ntxiv nrog rau kev txhim kho qhov ruaj khov, lwm yam khoom ntawm cov khoom siv hluav taws xob kub kuj tseem muaj cov kev hloov pauv, xws li cov khoom ntub dej thiab cov khoom siv pilling kuj tau txhim kho, thiab tus kov yog nruj dua;Cov pob txha elongation ntawm thermoplastic fiber txo qis nrog qhov nce ntawm qhov kub thiab txias, tab sis lub zog hloov me ntsis.Yog tias qhov ntsuas kub siab dhau lawm, ob qho tib si txo qis heev;Kev hloov pauv ntawm cov khoom dyeing tom qab cua sov qhov chaw sib txawv nrog ntau hom fiber ntau.
