Tam sim no, txoj kev loj hlob ntawm textile txoj kev loj hlob yog zoo ua, ntxiv ua, high-qib, diversification, modernization, kho kom zoo nkauj thiab functionalization, thiab lwm yam. Thiab cov txhais tau tias ntawm kev nce nqi ntxiv yog coj los txhim kho cov txiaj ntsig kev lag luam.
Dyeing thiab xov txheej txheem tuaj yeem txhim kho kev siv hluav taws xob thiab kev hnav khaub ncaws thiab kev lag luam ntawm textile.Nws yog cov txheej txheem tseem ceeb los kho textile, uas suav nrog pretreatment, dyeing thiab xov, thiab lwm yam.
Kev kho mob ua ntej
Fabrics uas tsis muaj dyeing thiab xov yog sib sau ua ke hu ua ntaub nyoos los yog grey fabrics.Ntawm, tsuas yog ib qho me me nkag mus rau hauv kev ua lag luam, thiab feem ntau ntawm lawv tseem yuav tsum tau ua tiav ntxiv rau hauv cov ntaub bleached, cov ntaub xim lossis cov ntaub ntawv hauv lub tshuab luam ntawv thiab dyeing rau cov neeg siv khoom.Feem ntau, grey fabrics muaj ib tug ntau ntawm impurities, raws li concomitant tshuaj ntawm paj rwb fibers, impurities, sizing tus neeg saib xyuas nyob rau hauv wrap yarn weaving,tshuaj fiber ntauspinning roj thiab staining greasy av, thiab lwm yam. Yog hais tias cov impurities thiab av tsis raug tshem tawm, lawv yuav tsis tsuas cuam tshuam cov xim ntxoov ntxoo thiab txhais tes zoo nkaus li ntawm fabrics, tab sis kuj yuav cuam tshuam rau cov dej nqus dej ua tau zoo, ua rau tsis sib xws tuag thiab tsis ci xim. ntxoov ntxoo.Tsis tas li ntawd lawv yuav cuam tshuam rau dyeing fastness.
Lub hom phiaj ntawm pretreatment yog tshem tawm txhua yam impurities los ntawm cov ntaub nyob rau hauv tus mob uas cov ntaub grey yog me ntsis puas, thiab ua grey ntaub los ua dawb thiab mos semi-tiav khoom nyob rau hauv zoo wettability rau dyeing thiab luam ntawv.Pretreatment yog txheej txheem npaj rau dyeing thiab luam ntawv txheej txheem.Nws tseem hu ua scouring thiab bleaching.Rau fabrics ntawm paj rwb thiab paj rwb blends, cov txheej txheem pretreatment muaj xws li kev npaj, singeing, desizing, scouring, bleaching thiab mercerizing, thiab lwm yam. Tab sis rau ntau hom fabrics, cov kev cai rau pretreatment yog txawv.Thiab cov xwm txheej ntau lawm hauv cov chaw tsim khoom sib txawv ntawm thaj tsam mus rau thaj tsam.Yog li ntawd, cov txheej txheem ua haujlwm thiab cov txheej txheem thev naus laus zis rau cov ntaub yog feem ntau sib txawv.
Dyeing
Dyeing yog cov txheej txheem ua haujlwm rau xim cov ntaub ntawv fiber ntau.Nws yog physicochemical los yog tshuaj ua ke ntawm dyes thiab fibers.Los yog nws yog txheej txheem uas dye yog chemically generated ntawm fiber ntau, ua rau tag nrho textile ua xim khoom.
Raws li cov khoom sib txawv dyeing, dyeing txoj kev yuav muab faib ua ntaub dyeing, xov paj dyeing thiab xoob fiber dyeing.Ntawm, ntaub dyeing yog siv dav tshaj plaws.Cov xov paj tuag feem ntau yog siv rau cov ntaub xim thiab cov ntaub knitted.Thiab xoob fiber ntau dyeing yog tsuas yog siv nyob rau hauv zus tau tej cov blends los yog tuab thiab compact fabrics, feem ntau yog wool fabrics.
Lub hom phiaj ntawm kev tshawb fawb dyeing yog xaiv thiab siv cov xim zoo nkauj, tsim thiab ua cov txheej txheem dyeing kom raug thiab tau txais cov khoom zoo dyeing tiav.
Ua tiav
Nyob rau hauv xyoo tas los no, textile finishing tau tsim sai heev.Nws twb tau tsim los ntawm kev ua si hauv cov yam ntxwv ntawm fiber ntau yam tsis muaj qhov cuam tshuam rau kev siv cov khoom siv tshiab thiab cov khoom siv los nthuav tawm cov ntaub ntawv zoo dua thiab siv tau ntev, xws li kev sib koom ua ke ntawm ntuj fibers thiab hluavtaws fibers hauv kev ua tau zoo thiab zoo li.Tom qab ua tiav, cov ntaub tuaj yeem tau txais cov haujlwm tshwj xeeb uas cov fiber ntau nws tus kheej tsis muaj keeb kwm.
Raws li lub hom phiaj ntawm kev ua tiav, cov ntaub ntawv xov xwm tuaj yeem muab faib ua ob peb yam hauv qab no:
(1) Ua fabrics nyob rau hauv huv si dav thiab ruaj khov loj thiab zoo li, xws li tentering, anti-shrinking, anti-wrinkling thiab kub teeb, thiab lwm yam. Nws yog hu ua qhov chaw finishing.
(2) Txhim kho tes kev xavntawm fabrics, xws li stiffening xov thiab softening xov, thiab lwm yam. Nws tuaj yeem txais kev siv tshuab, chemical method lossis ob qho tib si los ua cov ntaub.
(3) Txhim kho cov tsos ntawm cov ntaub, xws li xim ntxoov ntxoo, whiteness thiab drapability, thiab lwm yam, nrog rau calendering xov, whitening finishing thiab lwm yam xov uas yog los txhim kho qhov nto ntawm fabrics.
(4) Txhim kho lwm yam khoom siv hluav taws xob thiab kev hnav zoo, xws li nplaim hluav taws kub, dej-pov thawj tiav thiab huv si ntawm paj rwb ntaub thiabhydrophilic tiav, anti-static finishing thiab anti-pilling xov ntawm tshuaj fiber ntau fabrics.
Dyeing thiab Printing Kev kho dej khib nyiab
Ntawm kev lag luam textile, dyeing thiab luam ntawv kev lag luam yog ib qho kev siv dej loj.Raws li qhov nruab nrab, dej koom nrog tag nrho cov txheej txheem dyeing thiab tiav.Cov dyeing thiab luam ntawv cov dej khib nyiab muaj ntau cov dej, siab chroma thiab complex muaj pes tsawg leeg.Cov dej khib nyiab muaj cov dyes, sizing agents, auxiliaries, spinning oil, acid, alkali, fiber impurities thiab inorganic ntsev, thiab lwm yam. Nyob rau hauv cov qauv dyeing, cov nitro thiab amino tebchaw thiab cov hlau hnyav xws li tooj liab, chromium, zinc thiab arsenic, thiab lwm yam. . muaj lom lom lom zem heev, uas ua phem rau ib puag ncig.Yog li ntawd, kev tiv thaiv kev ua qias tuaj ntawm dyeing thiab luam ntawv cov dej khib nyiab thiab kev tsim khoom huv yog qhov tseem ceeb tshwj xeeb.
