active luam ntawv
Raws li lub npe qhia, peb cov dyes luam ntawv tau ua tiav los ntawm kev luam ntawv reactive. Cov qauv tsim ntawm reactive luam ntawv muaj ntau haiv neeg: cov nroj tsuag thiab paj, cov duab geometric, cov ntawv Askiv thiab cov xim sib txawv yog cov organically ua ke los qhia cov qauv tsim sib txawv los ntawm cov txheej txheem tsim. Cov ntaub ntawv zoo li no yog tsim rau ntau tus neeg thiab muaj lub sijhawm ua haujlwm ntev. Lub reactive luam ntawv ntaub muaj xim ci, xim zoo ceev, mos tes zoo nkaus li, tuaj yeem ntxuav tsis tu ncua, thiab zoo li tshiab tom qab siv mus ntev.
Feem ntau, reactive luam ntawv thiab dyeing tuaj yeem ua kom ntseeg tau tias nws yog ib puag ncig tus phooj ywg thiab tsis muaj teeb meem rau tib neeg, thiab cov xim thiab cov ntaub zoo zoo yam tsis muaj qhov nyuaj lossis muag.
pigment luam ntawv
Nws siv cov thermosetting los yog thermoplastic hluavtaws cob raws li ib tug binder, tov nrog insoluble pigments los ua pigment printing paste, uas yog siv rau saum npoo ntawm cov ntaub los ntawm mechanical los yog phau ntawv txoj kev, qhuav thiab ci los ua ib zaj duab xis, thiaj li hais tias cov xim yuav ua tau. nruj nreem npog ntawm fiber ntau, kom ua tiav lub hom phiaj ntawm kev luam ntawv thiab xim. Pigment printing xim paste feem ntau yog tsim los ntawm cov xim paste, nplaum, optical coupling agent thiab latex xim paste, uas tuaj yeem sib xyaw thaum siv.
Pigment printing yog txoj kev luam ntawv nrog tus nqi qis tshaj plaws hauv kev luam ntawv ntau lawm, vim tias cov xim luam ntawv yog qhov yooj yim, yuav tsum muaj cov txheej txheem tsawg tshaj plaws, thiab feem ntau tsis xav tau chav ntxhua khaub ncaws thiab dej ntxhua. Cov xim yog ci thiab nplua nuj xim thiab tuaj yeem siv rau txhua qhov textile fibers. Lawv lub teeb nrawm nrawm 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 yuav tsum tau ntxuav kom qhuav. Tsis tas li ntawd, cov txheej txheem tsis tshua muaj qhov sib txawv xim loj ntawm cov khoom sib txawv ntawm cov ntaub, thiab lub zog zais ntawm lub hauv paus xim kuj zoo heev thaum npog cov luam ntawv.
Nrog rov ua dua los yog ntxuav kom qhuav, cov xim luam tawm yuav maj mam ploj mus thiab cov xim yuav sib dua. Qhov no yog vim qhov kev sib hloov tas li thiab nplawm thaum lub sijhawm ntxuav, uas ua rau cov nplaum nplaum maj mam poob. Feem ntau, tom qab ntxuav 20-30 zaug, cov ntaub ntawv luam tawm no yuav muaj qhov tshwm sim pom tseeb. Vim yog daim ntawv thov ntawm resin thiab silicone softener nyob rau hauv cov txheej txheem tiav, cov xim ceev ntawm cov ntaub yog txhim kho. Nws tsim nyog sau cia tias cov xim tsaus yuav ploj mus yooj yim dua li lub teeb lossis xim xim.
Cov xim ua rau cov ntawv luam tawm ntawm cov ntaub ntawv nyuaj, uas tsis pom tseeb hauv cov xim teeb, tab sis tseem ceeb heev hauv cov xim tsaus. Cov xim tsis tshwj xeeb hardwear thiab xim tshwj xeeb yog tsaus. Npuag xws li rooj tog zaum yuav tsum tshwj xeeb tshaj yog zam cov xim tsaus.
qhov sib txawv ntawm ob
1. Cov txheej txheem sib txawv
Pigment luam ntawv siv cov thermosetting lossis thermoplastic hluavtaws cob ua cov ntaub ntawv sib xyaw, sib xyaw nrog cov xim tsis muaj kuab lom los ua cov xim luam ntawv, uas yog siv rau saum npoo ntawm cov ntaub los ntawm kev siv tshuab lossis phau ntawv, qhuav thiab ci los ua ib zaj duab xis, kom cov xim tuaj yeem npog nruj. Fiber, kom ua tiav lub hom phiaj ntawm kev luam ntawv thiab xim.
Reactive printing: Thaum lub sij hawm luam ntawv thiab dyeing txheej txheem, cov active pab pawg ntawm reactive dyes yog ua ke nrog fiber ntau molecules, thiaj li hais tias cov dyes thiab fibers tsim ib tug tag nrho.
2. Cov yam ntxwv sib txawv
Reactive printing thiab dyeing txhais tau hais tias tsis muaj azo thiab formaldehyde ntxiv thaum lub sij hawm luam ntawv thiab dyeing txheej txheem, tsis muaj tshuaj lom neeg lub cev, thiab xim tsis ploj thaum ntxuav. Cov xim thiab cov ntaub zoo zoo, tsis tawv lossis mos.
Pigment printing: Cov ntaub ntawv luam tawm yog ci thiab ci hauv cov xim thiab muaj lub teeb pom kev zoo. Nws tuaj yeem muab cov ntaub npuag, qhuav thiab muag muag, tshwj xeeb tshaj yog zoo heev rubbing ceev. Qhov qhuav thiab ntub dej nrawm nrawm tuaj yeem ncav cuag ntau dua lossis sib npaug li 4 (rau kev siv nkaus xwb) yog siv kom raug. Zoo heev ntxuav ceev thiab zoo huab cua permeability ntawm ntaub.
xaiv li cas
Cov txheej txheem ntau lawm ntawm pigment printing thiab reactive printing yog siv los piav qhia qhov kev luam ntawv zoo dua: feem ntau cov cav tov tuaj yeem pleev xim tus number case ncaj qha rau ntawm textile fabrics. Cov qauv siv tau yog cov khoom siv ncaj qha txhaj tshuaj, thiab cov txheej txheem tsim khoom yog yooj yim thiab meej. Feem ntau, cov txheej txheem tsim khoom siv tus cwj mem reactive yuav tsum tau mus los ntawm kev luam ntawv - kev txhaj tshuaj ncaj qha - ntxuav dej - steaming - ntxuav dej. Feem ntau hais lus, nws yuav tsum mus dhau ntawm kev ua ntej thiab ua ntej ntawm cov txheej txheem, thiab cov txheej txheem ntau lawm yog qhov nyuaj. Feem ntau muaj ntau cov xim luam tawm.
Koj tuaj yeem txiav txim siab seb qhov twg yog qhov zoo dua los ntawm cov xim ceev ntawm cov xim luam ntawv thiab reactive printing: xim ceev ntawm reactive luam ntawv feem ntau yog 4-5 qib, thiab seb nws yuav tsum tau faded feem ntau nyob ntawm seb cov dej ntxuav cov xim puas thiab seb cov hlwv kub kub yuav ploj mus. Cov xim ceev ceev ntawm cov xim feem ntau yog qib 3, thiab cov xim yuav tsis ploj thaum ntxuav los ntawm lub tshuab ntxhua khaub ncaws. Feem ntau hais lus, los ntawm kev xav ntawm xim ceev, xim ceev ntawm reactive luam ntawv yog qhov zoo.
Brightness qhia tias qhov twg yog qhov zoo dua: pigment printing lossis reactive printing: tus number case reactive tuaj yeem nkag mus rau hauv cov fiber ntau thiab xim yog ci heev. Lacquer number case feem ntau nkag mus rau hauv qhov chaw ntawm fiber ntau, thiab qhov ci ntsa iab yog qhov tsis muaj zog piv nrog cov haujlwm.
Piav seb qhov luam ntawv twg yog qhov zoo dua los ntawm qhov kev xav ntawm kev tiv thaiv ib puag ncig: cov txheej txheem xim number case jet luam ntawv feem ntau luam tawm rau ntawm daim ntaub, uas yooj yim decomposed los ntawm xwm thiab tag nrho raws li kev tiv thaiv ib puag ncig. Reactive luam ntawv nkag mus rau hauv pem hauv ntej thiab nraub qaum ntawm cov ntaub, uas yog qhov nyuaj rau decompose nyob rau hauv cov xwm thiab tsis yog ib puag ncig tus phooj ywg. Tam sim no, lub ntsiab lus ntawm kev tiv thaiv ib puag ncig yog tawm tswv yim thoob ntiaj teb, thiab cov pa phem raug tswj nruj heev. Yog li ntawd, dab tsi tsis tso cai los ntawm kev ua lag luam tsis tso cai. Peb xaiv pigment printing ntau.
Hais txog cov nqi tsim khoom: cov txheej txheem ntau lawm ntawm qhov kev tshwm sim yog lub luag haujlwm, cov nqi tsim khoom yog siab, xav tau ntau lub tshuab, thiab cov khoom tiav kuj tseem kim heev. Cov txheej txheem luam tawm cov xim pigment yog qhov yooj yim heev thiab tus nqi kuj tsawg. Yog li koj paub tias koj xaiv luam ntawv dab tsi.
