Cov txheej txheem sublimation
Sublimation yog txheej txheem tshuaj. Hauv cov ntsiab lus yooj yim, nws yog qhov uas cov khoom hloov mus rau hauv cov pa roj, tam sim ntawd, tsis dhau los ntawm cov kua theem hauv nruab nrab. Thaum nug dab tsi yog sublimation luam ntawv, nws pab kom paub tias nws yog hais txog cov xim nws tus kheej. Peb kuj hu qhov no dye-sublimation, raws li nws yog cov xim uas hloov lub xeev.
Sublimation Print feem ntau yog hais txog kev luam ntawv sublimation, uas yog, Thermal sublimation printing.
1. Nws yog lub tshuab luam ntawv hloov pauv hloov cov xim ntawm cov qauv mus rau lub dav hlau ntawm cov khaub ncaws lossis lwm yam receptors los ntawm kev kub siab.
2. Cov yam ntxwv tseem ceeb: Sublimation luam ntawv yog kev hloov tshuab luam ntawv, uas yog hais txog kev luam ntawv pigments lossis dyes rau ntawm daim ntawv, roj hmab lossis lwm cov khoom nqa. Raws li cov kev xav tau saum toj no, daim ntawv hloov chaw yuav tsum ua raws li cov qauv hauv qab no:
(1) Hygroscopicity 40--100g/㎡
(2) Lub zog tsim kua muag yog li 100kg / 5x20cm
(3) Cua permeability 500---2000l/min
(4) Nyhav 60--70g/㎡
(5) ph nqi 4.5--5.5
(6) Tsis muaj av
(7) Daim ntawv hloov pauv yog qhov zoo dua yog ua los ntawm softwood pulp. Ntawm lawv, chemical pulp thiab mechanical pulp yog txhua yam zoo dua. Qhov no tuaj yeem ua kom ntseeg tau tias daim ntawv decal yuav tsis nkig thiab daj thaum kho ntawm qhov kub thiab txias.
Hloov luam ntawv
Ntawd yog, hloov luam ntawv.
1. Ib txoj hauv kev luam ntawv textile. Pib thaum xyoo 1960s. Ib txoj kev luam ntawv uas muaj qee yam xim yog thawj zaug luam tawm ntawm lwm cov ntaub ntawv xws li ntawv, thiab tom qab ntawd cov qauv raug xa mus rau cov ntaub los ntawm kev kub kub thiab lwm txoj kev. Nws feem ntau yog siv rau kev luam ntawv ntawm cov tshuaj fiber ntau knitwear thiab khaub ncaws. Hloov luam ntawv mus los ntawm cov txheej txheem xws li dye sublimation, migration, melting, thiab number case txheej peeling.
2. Basic parameters:
Dyes haum rau kev hloov luam ntawv yuav tsum ua raws li cov hauv qab no:
(1) Cov dyes rau kev hloov luam ntawv yuav tsum tau ua kom tag nrho sublimated thiab tsau rau ntawm cov fibers hauv qab 210 ° C, thiab tuaj yeem tau txais kev ntxuav sai sai thiab ironing ceev.
(2) Cov dyes ntawm kev hloov luam ntawv tuaj yeem ua tiav sublimated thiab hloov mus rau hauv cov pa roj-theem dye macromolecules tom qab tau rhuab, condensed rau saum npoo ntawm cov ntaub, thiab tuaj yeem diffuse rau hauv fiber ntau.
(3) Cov xim siv rau kev hloov luam ntawv muaj qhov sib txuam me me rau cov ntawv hloov pauv thiab qhov loj affinity rau cov ntaub.
(4) Cov xim rau kev hloov luam ntawv yuav tsum muaj xim ci thiab ci.
Daim ntawv hloov tsheb siv yuav tsum muaj cov yam ntxwv hauv qab no:
(1) Yuav tsum muaj lub zog txaus.
(2) Cov affinity rau xim number case yog me me, tab sis daim ntawv hloov tsheb yuav tsum muaj kev pab zoo rau number case.
(3) Daim ntawv hloov tsheb yuav tsum tsis txhob deformed, nkig thiab yellowed thaum lub sij hawm luam ntawv.
(4) Daim ntawv hloov tsheb yuav tsum muaj hygroscopicity. Yog tias hygroscopicity tsis zoo, nws yuav ua rau cov xim number case sib tshooj; Yog hais tias lub hygroscopicity loj heev, nws yuav ua rau deformation ntawm daim ntawv hloov chaw. Yog li ntawd, tus muab tub lim yuav tsum nruj me ntsis tswj thaum tsim cov ntawv hloov chaw. Nws yog qhov tsim nyog los siv semi-filler hauv kev lag luam ntawv.
Sublimation vs Kub Hloov
- Peb tuaj yeem pom qhov txawv ntawm DTF thiab Sublimation.
- DTF siv PET zaj duab xis ua qhov nruab nrab, thaum Sublimation siv ntawv ua qhov nruab nrab.
2.Print Runs - Ob txoj hauv kev yog qhov zoo rau kev luam ntawv me me, thiab vim yog tus nqi pib ntawm dye-sub, yog tias koj tsuas yog yuav luam ib lub t-shirt txhua ob peb lub hlis, ces koj tuaj yeem pom cov cua sov hloov mus. zoo dua rau koj.
3.Thiab DTF tuaj yeem siv tus cwj mem dawb, thiab Sublimation tsis yog.
4. Qhov sib txawv tshaj plaws ntawm kev hloov pauv kub thiab sublimation yog tias nrog sublimation, nws tsuas yog tus cwj mem uas hloov mus rau cov khoom siv. Nrog rau cov txheej txheem hloov hluav taws xob, feem ntau muaj cov txheej txheem hloov pauv uas yuav raug xa mus rau cov khoom siv thiab.
5.Qhov hloov pauv DTF tuaj yeem ua tiav cov duab zoo nkauj thiab zoo dua rau sublimation. Cov duab zoo yuav zoo dua thiab pom tseeb dua nrog cov ntsiab lus polyester ntau dua ntawm cov ntaub. Rau DTF, tus qauv tsim ntawm cov ntaub zoo li mos rau qhov kov.
6. Thiab Sublimation tsis tuaj yeem ua haujlwm ntawm paj rwb ntaub, tab sis DTF muaj nyob rau ntawm yuav luag txhua hom ntaub.
Direct to Garment (DTG) vs Sublimation
- Print Runs - DTG kuj haum rau cov ntawv sau me me, zoo ib yam li sublimation printing. Koj yuav pom txawm li cas los xij tias thaj chaw luam ntawv yuav tsum muaj tsawg dua. Koj tuaj yeem siv dye-sub los npog tag nrho cov ris tsho hauv kev luam tawm, qhov DTG txwv koj. Ib nrab ntawm ib lub 'meter' square yuav yog ib lub laub, nws yog advisable mus lo rau ib ncig ntawm 11.8 "mus rau 15.7".
- Cov ntsiab lus - Nrog DTG tus number case disperses, yog li cov duab thiab cov duab nrog cov ntsiab lus yuav tshwm ntau pixelated dua li lawv ua ntawm koj lub computer screen. Sublimation luam ntawv yuav muab cov ncauj lus kom ntxaws thiab nthuav dav.
- Xim - Fades, glows thiab gradients tsis tuaj yeem rov ua dua nrog DTG luam ntawv, tshwj xeeb tshaj yog rau cov khaub ncaws muaj xim. Tsis tas li vim cov xim palettes siv cov zaub ntsuab thiab paj yeeb, thiab xim hlau tuaj yeem yog qhov teeb meem. Sublimation luam tawm tawm thaj chaw dawb tsis tau luam tawm, qhov DTG siv cov ntawv dawb, uas yog siv tau thaum koj tsis xav luam tawm ntawm cov khoom dawb.
- Lub neej ntev - DTG siv tus number case ncaj qha mus rau lub tsoos tsho, whereas nrog sublimation luam ntawv tus number case mus tas li ua ib feem ntawm cov tsoos tsho. Qhov no txhais tau hais tias nrog DTG luam ntawv koj yuav pom tias koj tus qauv tsim yuav hnav, tawg, tev, lossis rub tawm lub sijhawm.
