Digital printing yog txheej txheem luam ntawv uas siv cov thev naus laus zis thev naus laus zis rau kev luam ntawv. Nws yog cov khoom siv high-tech integrating machinery, computer electronic information technology; screen printing yuav tsum tau siv cov tshuaj ntsuam luam ntawv pwm. Cov txheej txheem luam ntawv ntawm kev luam ntawv, luam ntawv thiab ziab yog ua tiav nyob rau hauv ob peb kauj ruam.Qhov tshwj xeeb sib txawv ntawm ob yog raws li hauv qab no:
1. Hom ntawm cov ntaub ntawv luam tawm tsis txawv ntau
Cov luam ntawv digital tau muab faib ua tsib pawg: acid digital printing, reactive digital printing, pigment digital printing, dispersed thermal transfer printing thiab dispersed direct-injection digital printing. Cov ntawv luam tawm cov kua qaub yog tsim rau cov ntaub plaub, txhob lo lo ntxhuav thiab lwm yam protein fibers thiab nylon fibers thiab lwm yam ntaub. Digital luam ntawv reactive dye number case yog tsim rau cov luam ntawv digital ntawm paj rwb, linen, viscose fiber thiab txhob lo lo ntxhuav thiab lwm yam ntaub, thiab tuaj yeem siv rau digital printing ntawm paj rwb fabrics, silk fabrics, wool fabrics thiab lwm yam natural fibers. Cov luam ntawv xim xim number case yog tsim rau digital inkjet xim luam ntawv ntawm paj rwb fabrics, silk fabrics, tshuaj fiber ntau thiab blended fabrics, knitted fabrics, sweaters, phuam, pam. Digital luam ntawv thermal hloov tus number case yog tsim rau hloov luam ntawv ntawm polyester, non-woven fabrics, ceramics thiab lwm yam ntaub ntawv. Cov luam ntawv ncaj qha-txhaj tshuaj dispersion number case yog tsim rau digital luam ntawv ntawm polyester fabrics, xws li cov ntaub dai kom zoo nkauj, chij ntaub, banners, thiab lwm yam.
Piv nrog rau cov luam ntawv digital, ib txwm siv tshuaj ntsuam luam ntawv tsis muaj qhov zoo dua ntawm cov ntaub ntawv luam tawm. Ua ntej, cov ntawv luam tawm ntawm cov ntawv luam tawm ib txwm txwv. Lub inkjet dav ntawm kev lag luam digital inkjet tshuab luam ntawv loj tuaj yeem ncav cuag li 3 ~ 4 meters, uas tuaj yeem luam tawm tsis tu ncua, thiab qhov ntev tsis txwv. Lawv tuaj yeem tsim tag nrho cov kab ntau lawm; Ob Ntawm qee cov ntaub ntawv, cov ntawv luam tawm dej raws li tus cwj pwm tsis tuaj yeem ua tau zoo. Vim li no, tsuas yog cov kuab tshuaj raws li cov kuab tshuaj tuaj yeem siv rau kev luam ntawv, thaum lub tshuab luam ntawv digital tuaj yeem siv cov kua dej raws li inkjet luam ntawv ntawm txhua yam khoom siv, uas zam kev siv ntau. Flammable thiab explosive non-environmentally tus phooj ywg hnyav hnyav.
2. Cov xim ntawm cov luam ntawv digital yog vivid
Qhov zoo tshaj plaws ntawm cov luam ntawv digital yog qhov tseem ceeb hauv kev ua kom zoo ntawm cov xim thiab cov qauv. Ua ntej ntawm tag nrho cov, hais txog cov xim, cov luam ntawv digital inks tau muab faib ua dye-based inks thiab pigment-based inks. Cov xim ntawm dyes yog ci dua li cov xim. Acid digital printing, reactive digital printing, dispersion thermal hloov luam ntawv thiab dispersion direct-injection digital printing tag nrho siv dye-based inks. Txawm hais tias cov xim digital luam ntawv siv cov xim ua xim, lawv txhua tus siv nano-scale pigment pastes. Rau ib tus cwj mem tshwj xeeb, tsuav yog npaj siab rau ICC nkhaus, cov xim xim tuaj yeem ncav cuag qhov kawg.
Cov xim ntawm cov tshuaj ntsuam luam ntawv ib txwm ua raws li qhov sib piv ntawm plaub-xim dots, thiab qhov thib ob yog tswj los ntawm kev luam ntawv ua ntej ink toning, thiab cov xim nthuav tawm tsis zoo li cov luam ntawv digital. Tsis tas li ntawd, hauv kev luam ntawv digital, cov xim xim xim siv nano-scale pigment paste, thiab cov xim hauv cov xim xim yog dej-soluble. Txawm tias nyob rau hauv dispersion-hom sublimation hloov number case, cov xim kuj yog nano-scale. Qhov kom zoo dua ntawm kev tshuaj ntsuam luam ntawv yog nyob rau hauv tshwj xeeb luam ntawv paste, xws li kub, nyiaj, pearlescent xim, tawg nyhuv, bronzing flocking nyhuv, suede foaming nyhuv thiab hais txog. Tsis tas li ntawd, kev tshuaj ntsuam luam ntawv tuaj yeem luam 3D cov teebmeem peb sab, uas nyuaj rau kev ua tiav nrog cov luam ntawv digital tam sim no.
3. Digital printing yog mos thiab silk screen printing muaj xim ceev ceev
Cov khoom tseem ceeb ntawm cov khoom luam ntawv muaj xws li cov khoom nto, uas yog, tes (softness), tackiness, tsis kam, xim ceev rau rubbing, xim ceev rau soaping; kev tiv thaiv ib puag ncig, uas yog, txawm tias nws muaj formaldehyde, azo, pH, carcinogenic Aromatic amines, phthalates, thiab lwm yam GB/T 18401-2003 "National Basic Safety Technical Specifications for Textile Products" ua kom pom tseeb cov kev cai rau qee yam ntawm cov khoom teev. saum toj no.
Hauv kev tshuaj ntsuam luam ntawv ib txwm muaj, ntxiv rau qhov ntsuas dej thiab tso tawm, lwm hom kev luam ntawv muaj cov txheej txheem muaj zog dua. Qhov no yog vim hais tias cov ntsiab lus resin raws li ib tug binder nyob rau hauv lub printing number case formulation yog kuj siab, thiab tus number case yog kuj loj. Txawm li cas los xij, cov luam ntawv digital yeej tsis muaj txheej txheej, thiab cov luam ntawv yog lub teeb, muag muag, thiab muaj cov nplaum zoo. Txawm hais tias nws yog digital printing nrog cov xim, vim hais tias cov ntsiab lus resin nyob rau hauv cov mis yog heev me me, nws yuav yeej tsis cuam tshuam rau tes. Acid digital printing, reactive digital printing, dispersive thermal hloov luam ntawv thiab dispersive direct-injection digital printing, cov no yog uncoated thiab tsis cuam tshuam rau tus thawj ntaub.
Nyob rau hauv luv luv, cov luam ntawv digital muaj ntau yam ntawm cov ntaub ntawv luam tawm, cov xim ci, cov qauv zoo, zoo tes zoo thiab muaj zog tiv thaiv ib puag ncig ntawm cov khoom luam tawm, uas yog nws cov yam ntxwv zoo. Txawm li cas los xij, cov tshuab luam ntawv inkjet yog kim, nrog cov khoom siv siab thiab cov nqi tu, uas yog nws qhov tsis zoo. Nws yog ib qho nyuaj los txhim kho qhov ceev ceev thiab rubbing ceev ntawm cov khoom luam tawm digitally; nws yog ib qho nyuaj los tsim cov xim dawb ruaj khov, ua rau kev luam ntawv zoo dua ntawm cov ntaub dub thiab tsaus; vim muaj kev txwv ntawm inkjet printheads, nws yog ib qho nyuaj rau tsim Printing inks nrog cov teebmeem tshwj xeeb; luam ntawv tej zaum yuav tsum tau ua ua ntej thiab tom qab ua tiav, uas yog qhov nyuaj tshaj li kev luam ntawv ib txwm muaj. Cov no yog qhov tsis zoo ntawm kev luam ntawv digital tam sim no.
