Pigment printing vs dye printing

Kev luam ntawv

Lub npe hu ua luam ntawv yog cov txheej txheem ua cov dye lossis xim rau hauv cov xim muab tshuaj, hauv zos siv nws rau textiles thiab luam ntawv qauv.Txhawm rau ua kom tiav cov ntawv luam tawm, cov txheej txheem siv yog hu ua txheej txheem luam ntawv.

Pigment luam ntawv

Pigment printing yog ib txoj kev luam ntawv uas cov xim yog kho rau ntawm cov ntaub los ntawm cov ntaub ntawv siab molecular polymer (adhesive) thiab dej-insoluble xim (pigments) los ua ib qho ruaj khov, pob tshab thiab hnav-tiv taus cov xim ntawm cov ntaub.

Xim luam ntawv

Nyob rau hauv cov nqe lus ntawm lub mechanism ntawm dye dyeing fiber, luam ntawv thiab dyeing yog tib yam, tshwj tsis yog tias nyob rau hauv printing, cov xim ntawm ib co xim yog siv nyob rau hauv lub zos textile raws li qhov yuav tsum tau ntawm cov qauv, thiab tom qab ib tug tej yam kev kho mob, cov xim yog siv nyob rau hauv lub zos textile raws li qhov yuav tsum tau ntawm cov qauv, thiab tom qab ib tug tej yam kev kho mob, cov xim yog siv nyob rau hauv lub zos ntawm textiles raws li qhov yuav tsum tau ntawm tus qauv, thiab tom qab ib tug tej yam kev kho mob. dyes cov fiber ntau, thiab tom qab ntawd cov khoom luam tawm nrog ib lossis ntau xim tau txais ntawm cov ntaub ntawv.Yog li ntawd, kev luam ntawv kuj tuaj yeem hais tias yog "dyeing hauv zos".

Coloring txoj cai ntawm cov xim

Pigment printing yog ib txoj kev luam ntawv uas txwv tsis pub cov nplaum los ntawm kev ua kom ruaj khov, pob tshab thiab hnav-tiv taus zaj duab xis ntawm cov ntaub, yog li txhawm rau kho cov xim ntawm cov ntaub.

Coloring cov ntaub ntawv ntawm dyes

Dyeing yog txheej txheem ua haujlwm uas cov ntaub ntawv textile tau txais cov xim ci thiab ruaj khov los ntawm lub cev, tshuaj lom neeg lossis lub cev-tshuaj lom neeg ua ke ntawm dyes (los yog pigments) thiab cov ntaub ntawv textile.

Qhov zoo thiab qhov tsis zoo

Pigment luam ntawv

Qhov zoo:

•Kev siv yooj yim, txheej txheem yooj yim, kev ua haujlwm siab, tuaj yeem txo cov dej khib nyiab

•Dav chromatogram, siab lightfastness, clear print kab thiab contours

•Nws yog qhov tsim nyog rau kev luam ntawv tshwj xeeb, thiab tuaj yeem siv rau kev tso tawm thiab tiv thaiv dyeing luam ntawv

•Ib qho yooj yim xim txuam thiab zoo xim lub teeb luam tawm

•Nws yog tsim rau cov ntaub luam tawm ntawm ntau yam ntaub ntawv fiber ntau, tshwj xeeb tshaj yog cov ntaub sib xyaw.

Qhov tsis zoo:

• Cov tes tsis zoo, tsis zoo qhuav thiab ntub dej nrawm nrawm

• Kev siv cov kerosene hauv emulsified paste pollutes huab cua;Feem ntau ntawm cov monomers siv los npaj cov nplaum yog tshuaj lom

• Cov xim ci ci tsis yog ci li cov xim luam ntawv nrog cov qauv sib npaug

• Cov nplaum nplaum yog yooj yim tev thiab thaiv lub mesh

Dye printing (coj reactive dyes ua piv txwv)

Qhov zoo:

• Muaj ntau ntau yam, ua tiav chromatograms thiab ci xim

• Nws yog qhov yooj yim los npaj cov xim pleev xim, txheej txheem luam ntawv yooj yim, cov nyhuv zoo thiab ob peb yam tsis xws luag

• Zoo ceev ceev rau kev kho ntub dej

• Tsawg nqi luam ntawv thiab xim sib txuam yooj yim

Qhov tsis zoo:

• Feem ntau ntawm lawv tsis tiv taus cov tshuaj chlorine, thiab tus nqi fixation tsawg.Ib co reactive dyes muaj kev ncaj ncees (affinity), uas yog ib qho yooj yim los ua staining thaum soaping, tshwj xeeb tshaj yog thaum luam ntawv sib sib zog nqus thiab tuab xim.

Qhov txawv:

Qhov sib txawv loj tshaj plaws ntawm dye printing thiab pigment printing yog pigment printing yog ua ke nrog cov ntaub los ntawm lub cev kev sib raug zoo, thaum dye printing yog ncaj qha ua ke nrog ntaub los ntawm van der Waals quab yuam.

Pigment luam ntawv tuaj yeem siv rau kev ua cov khoom siv fiber ntau.Nws muaj ntau qhov zoo hauv kev luam ntawv ntawm cov khoom sib xyaw thiab cov ntaub sib txuas.Nws muaj cov txheej txheem yooj yim, dav chromatography, pom meej paj zoo, tab sis tsis zoo txhais tes xav thiab tsis tshua muaj rubbing ceev.Lawv lub teeb ceev ceev thiab ziab kom ceev ceev yog qhov zoo, txawm tias zoo heev, yog li lawv tau siv dav hauv cov ntaub zoo nkauj, ntaub ntaub thiab cov khaub ncaws uas xav tau kev tu kom qhuav.

Yuav ua li cas paub qhov txawv ntawm dye printing thiab pigment printing

Pigment printing thiab dye printing tuaj yeem paub qhov txawv los ntawm kev sib piv qhov sib txawv ntawm qhov sib txawv ntawm cov ntawv luam tawm thiab qhov tsis tau luam tawm ntawm tib cov ntaub.Lub tes xav ntawm cov xim luam tawm yog me ntsis nyuaj dua li ntawm qhov chaw tsis tau luam tawm, uas tej zaum yuav yog me ntsis thicker.Yog hais tias cov ntaub yog luam tawm nrog dyes, tsis muaj qhov pom tseeb hardness qhov txawv ntawm qhov luam tawm thiab qhov tsis tau luam tawm.
