Nyob rau hauv resist printing.Cov khoom uas tiv thaiv dyeing yuav tsum xub muab tso rau hauv daim ntaub, thiab tom qab ntawd daim ntaub yog dyed.Tom qab cov ntaub yog dyed, qhov kev tawm tsam yuav raug tshem tawm, thiab cov qauv tsim tshwm nyob rau hauv cov cheeb tsam uas tiv thaiv tau luam tawm.

Kuj tseem muaj lwm hom kev luam ntawv, piv txwv li, sublistatic printing thiab flock printing.Nyob rau hauv lub ces kaum, tus qauv tsim yog thawj zaug luam tawm rau hauv daim ntawv thiab tom qab ntawd daim ntawv nrog cov qauv tsim yog nias tawm tsam cov ntaub los yog tsoos tsho xws li T-shirts.Thaum tshav kub siv, cov qauv tsim tau xa mus rau hauv cov ntaub los yog tsoos tsho.Nyob rau hauv lub tom kawg, shourt fibrous cov ntaub ntawv yog luam tawm nyob rau hauv cov qauv mus rau fabrics nrog kev pab los ntawm adhesives.Electronstatic flocking feem ntau yog siv.

Cov cuab yeej luam ntawv

Kev luam ntawv tuaj yeem ua los ntawm cov menyuam luam ntawv, tshuaj ntsuam luam ntawv lossis, tsis ntev los no, cov khoom siv inkjet luam ntawv.

1. Roller Printing

Lub tshuab luam ntawv rau cov menyuam feem ntau muaj lub tog raj kheej loj hauv nruab nrab (los yog hu ua lub tais siab) npog nrog roj hmab los yog ob peb lub plies ntawm ntaub plaub-linen blended ntaub uas muab lub tog raj kheej nrog ib tug du thiab compressively elastic nto.Ob peb tooj liab rollers engraved nrog cov qauv tsim los luam tawm yog teem nyob ib ncig ntawm lub tog raj kheej siab, ib tug menyuam rau txhua xim, nyob rau hauv kev sib cuag nrog lub siab lub tog raj kheej.Raws li lawv tig, txhua tus engraved luam ntawv rollers, uas tau tsav zoo, kuj tseem tsav nws cov rooj tog rau cov menyuam, thiab tom qab ntawd nqa cov ntawv luam tawm los ntawm nws lub thawv xim mus rau lub tshuab luam ntawv engraved.Cov hniav hlau ntse hu ua tus kws kho mob hniav tshem tawm cov khoom siv ntau dhau los ntawm cov tshuab luam ntawv, thiab lwm cov hniav hu ua lint kws kho hniav txhuam tawm cov lint lossis cov av uas ntes tau los ntawm cov tshuab luam ntawv.Cov ntaub yuav tsum tau luam tawm yog pub ntawm cov tshuab luam ntawv thiab lub tog raj kheej siab, ua ke nrog ib daim ntaub grey rov qab los tiv thaiv lub ntsej muag ntawm lub tog raj kheej kom tsis txhob muaj xim yog tias cov xim pleev xim nkag mus rau hauv daim ntaub.

Cov menyuam luam ntawv tuaj yeem muab cov khoom tsim tau zoo heev tab sis kev npaj ntawm cov ntawv luam ntawv cov menyuam yaus yog kim, uas, xyaum ua, ua rau nws tsuas yog haum rau kev ua haujlwm ntev.Tsis tas li ntawd, txoj kab uas hla ntawm cov menyuam luam ntawv txwv cov qauv loj.

2. Kev tshuaj ntsuam luam ntawv

Screen luam ntawv, ntawm qhov tod tes, yog tsim rau kev txiav txim me me, thiab tshwj xeeb tshaj yog haum rau luam ntawv stretch fabrics.Hauv kev tshuaj ntsuam luam ntawv, woven mesh printing screen yuav tsum tau npaj ua ntej raws li cov qauv tsim los luam, ib qho rau txhua xim.Ntawm qhov screen, thaj chaw uas tsis muaj xim pleev xim yuav tsum nkag mus yog coated nrog cov yeeb yaj kiab tsis sib haum tawm hauv qhov seem ntawm qhov screen interstices qhib kom tso cai luam paste nkag los ntawm lawv.Kev luam ntawv yog ua los ntawm kev yuam cov ntawv luam tawm tsim nyog los ntawm cov qauv mesh rau ntawm cov ntaub hauv qab.Lub vijtsam yog npaj los ntawm txheej txheej ntawm lub vijtsam nrog photogelatin ua ntej thiab ua kom pom cov duab tsis zoo ntawm cov qauv tsim rau nws thiab tom qab ntawd nthuav tawm nws rau lub teeb uas kho thiab cov txheej txheem tsis sib haum xeeb ntawm qhov screen.Cov txheej yog ntxuav tawm los ntawm cov cheeb tsam uas cov txheej tsis tau kho, tawm hauv cov interstices hauv qhov screen qhib.Kev tshuaj ntsuam luam ntawv ib txwm yog lub tshuab luam ntawv tiaj tus, tab sis lub tshuab luam ntawv teb kuj tseem nrov heev rau kev tsim khoom loj dua.

3. Inkjet luam ntawv

Nws tuaj yeem pom tau tias rau cov menyuam luam ntawv lossis kev tshuaj ntsuam luam tawm qhov kev npaj yog lub sijhawm thiab nyiaj txiag siv txawm tias Computer Aided Design (CAD) tau siv dav hauv ntau lub tsev luam ntawv los pab tsim kev npaj.Cov qauv tsim los luam tawm yuav tsum tau txheeb xyuas los txiav txim siab seb cov xim twg tuaj yeem koom nrog, thiab tom qab ntawd cov qauv tsis zoo yog npaj rau txhua xim thiab xa mus rau cov ntawv luam ntawv lossis cov ntxaij vab tshaus.Thaum lub sij hawm tshuaj ntsuam luam ntawv nyob rau hauv ntau lawm, teb los yog tiaj tus, cov ntxaij vab tshaus yuav tsum tau hloov thiab ntxuav tsis tu ncua, uas kuj yog lub sij hawm thiab siv zog.

Yuav kom ua tau raws li niaj hnub kev lag luam xav tau cov lus teb ceev thiab cov khoom me me inkjet luam ntawv thev naus laus zis tau dhau los siv.

Inkjet luam ntawv ntawm textiles siv thev naus laus zis zoo ib yam li siv hauv ntawv luam ntawv.Cov ntaub ntawv digital ntawm tus tsim tsim siv CAD system tuaj yeem xa mus rau lub tshuab luam ntawv inkjet (lossis feem ntau hu ua lub tshuab luam ntawv digital inkjet, thiab cov ntawv luam tawm nrog nws tuaj yeem hu ua digital textiles) ncaj qha thiab luam tawm rau hauv cov ntaub.Piv nrog rau cov tshuab luam ntawv ib txwm siv, cov txheej txheem yog yooj yim thiab tsawg lub sij hawm thiab kev txawj ntse yuav tsum tau raws li cov txheej txheem yog tsis siv neeg.Tsis tas li ntawd, yuav ua rau muaj kuab paug tsawg.

Feem ntau hais lus, muaj ob lub hauv paus ntsiab lus rau inkjet luam ntawv rau textiles.Ib qho yog Continuous Ink Jetting (CIJ) thiab lwm qhov yog hu ua "Drop on Demand" (DOD).Nyob rau hauv cov ntaub ntawv qub, lub siab heev (nyob ib ncig ntawm 300 kPa) tau tsim los ntawm tus number case muab twj tso kua mis quab yuam tus number case tsis tu ncua mus rau lub nozzle, txoj kab uas hla ntawm uas feem ntau yog hais txog 10 mus rau 100 micrometers.Nyob rau hauv lub siab zaus vibration tshwm sim los ntawm ib tug peizoelectric vibrator, tus number case yog ces tawg mus rau hauv ib tug khiav ntawm tee dej thiab ejected ntawm lub nozzle ntawm ceev heev.Raws li cov qauv tsim, lub khoos phis tawj yuav xa cov teeb liab mus rau lub charger electrode uas hluav taws xob them tus number case droplets.Thaum dhau los ntawm cov deflection electrodes, cov tee dej uas tsis muaj nqi yuav mus ncaj nraim mus rau hauv ib qho kev sib sau ua ke thaum cov kua mem hluav taws xob yuav raug xa mus rau hauv cov ntaub los ua ib feem ntawm cov qauv luam tawm.

Hauv cov txheej txheem "poob ntawm qhov xav tau", cov kua mem dej tau muab raws li lawv xav tau.Qhov no tuaj yeem ua tiav los ntawm kev hloov pauv hluav taws xob.Raws li cov qauv yuav tsum tau luam tawm, lub khoos phis tawj xa cov cim taw qhia mus rau lub piezoelectric ntaus ntawv uas ua rau deforms thiab ua rau lub siab ntawm cov number case chamber los ntawm cov khoom siv nruab nrab hloov tau.Lub siab ua rau cov kua number case tawm ntawm lub nozzle.Lwm txoj kev uas feem ntau siv hauv DOD cov txheej txheem yog los ntawm txoj kev siv hluav taws xob thermal.Hauv kev teb rau lub khoos phis tawj qhia tias lub tshuab cua sov tsim cov npuas hauv lub tshuab luam ntawv, thiab lub zog nthuav dav ntawm cov npuas cuases number case droplets yuav raug tshem tawm.

Cov txheej txheem DOD yog pheej yig dua tab sis kev luam ntawv ceev kuj tseem qis dua li cov txheej txheem CIJ.Txij li thaum tus number case droplets yog ejected tsis tu ncua, nozzle clogging teeb meem yuav tsis tshwm sim raws li CIJ txheej txheem.

Cov tshuab luam ntawv inkjet feem ntau siv ua ke ntawm plaub xim, uas yog, cyan, magenta, daj thiab dub (CMYK), los luam cov qauv nrog ntau xim, thiab yog li plaub lub taub hau luam ntawv yuav tsum tau sib sau ua ke, ib qho rau txhua xim.Txawm li cas los xij qee lub tshuab luam ntawv tau nruab nrog 2 * 8 lub taub hau luam ntawv kom theoretically mus txog 16 xim ntawm tus number case tuaj yeem luam tawm.Kev daws teeb meem ntawm cov tshuab luam ntawv inkjet tuaj yeem ncav cuag 720 * 720 dpi.Cov ntaub ntawv uas tuaj yeem luam tawm nrog cov tshuab luam ntawv inkjet muaj ntau yam ntawm cov fibers ntuj, xws li paj rwb, txhob lo lo ntxhuav thiab ntaub plaub, rau hluavtaws fibers, xws li polyester thiab polyamide, yog li ntawd muaj ntau hom inks yuav tsum tau raws li qhov xav tau.Cov no suav nrog cov inks reactive, kua qaub inks, disperse inks thiab txawm pigmented inks.

Ntxiv nrog rau cov ntaub ntawv luam tawm, cov tshuab luam ntawv inkjet kuj tseem siv tau los luam T-shirt, sweatshirts, tsho polo, me nyuam hnav, aprons thiab phuam.
