Disperse dyes tuaj yeem siv rau hauv ntau yam thev naus laus zis thiab tuaj yeem yooj yim xim tsis zoo sib xyaw ua ke nrog cov dyes disperse, xws li polyester, nylon, cellulose acetate, viscose, hluavtaws velvet, thiab PVC.Lawv kuj tuaj yeem siv los ua xim cov nyees khawm yas thiab fasteners.Vim yog cov qauv molecular, lawv muaj qhov tsis muaj zog ntawm polyester, thiab tsuas yog tso cai rau cov xim pastel kom dhau mus rau nruab nrab tones.Polyester fibers muaj qhov los yog cov raj hauv lawv cov qauv.Thaum rhuab mus rau 100 ° C, lub qhov los yog cov raj nthuav dav kom tso cai rau cov xim xim nkag mus.Kev nthuav dav ntawm lub qhov hws yog txwv los ntawm cov cua kub ntawm cov dej - kev lag luam dyeing ntawm polyester yog nqa tawm ntawm 130 ° C hauv cov khoom siv zog!
Raws li Linda Chapman tau hais, thaum siv disperse dyes rau thermal hloov, tag nrho cov xim tuaj yeem ua tiav.
Kev siv cov dyes disperse ntawm ntuj fibers (xws li paj rwb thiab ntaub plaub) tsis ua haujlwm zoo, tab sis nws tuaj yeem siv ua ke nrog Reactive Dyeing los ua polyester / paj rwb blends.Cov thev naus laus zis no yog siv hauv kev lag luam raws li kev tswj xyuas.
Disperse Dyeing
Disperse Dyeing technology:
dye 100 grams ntawm ntaub hauv 3 liv dej.
Ua ntej dyeing, nws yog ib qho tseem ceeb uas yuav tau xyuas seb cov ntaub puas "npaj rau dyeing" (PFD) los yog xav tau kev txhuam kom tshem tawm cov roj, roj lossis hmoov txhuv nplej siab.Muab ob peb tee dej txias rau ntawm daim ntaub.Yog tias lawv nqus tau sai, tsis tas yuav yaug.Txhawm rau tshem tawm cov hmoov txhuv nplej siab, cov pos hniav thiab roj, ntxiv 5 ml Synthrapol (ib qho tshuaj ntxuav tes uas tsis yog-ionic) thiab 2-3 liv dej rau txhua 100 grams ntawm cov khoom.Do maj mam rau 15 feeb, ces yaug kom huv si hauv dej sov.Cov tshuaj detergents hauv tsev tuaj yeem siv tau, tab sis cov alkaline residues tuaj yeem cuam tshuam cov xim kawg lossis ntxuav ceev.
Cov dej kub hauv lub thawv tsim nyog (tsis txhob siv hlau, tooj liab lossis txhuas).Yog tias siv dej los ntawm cov dej tawv, ntxiv 3 grams Calgon los pab tiv thaiv nws cov alkalinity.Koj tuaj yeem siv daim ntawv xeem los ntsuas dej.
Ntsuas cov hmoov dyeing dispersed (0.4gm rau lub teeb xim thiab 4gm rau cov xim tsaus), thiab nphoo ib me ntsis dej sov los ua ib tug tov.
Ntxiv cov tshuaj zas xim ua ke nrog 3 grams ntawm dispersant rau lub da dej dye, thiab do kom huv si nrog ib tug ntoo, stainless hlau los yog yas diav.
Ntxiv cov ntaub rau dyeing da dej thiab do maj mam maj mam nce qhov kub ntawm 95-100 ° C hauv 15-30 feeb (yog tias dyeing acetate, khaws qhov kub ntawm 85 ° C).Qhov ntev ntawm cov ntaub nyob twj ywm nyob rau hauv lub dye da dej, lub thicker lub ntxoov ntxoo.
Cia lub da dej txias rau 50 ° C, tom qab ntawd xyuas cov xim.Ntxiv cov tshuaj zas xim ntxiv kom nws lub zog, thiab tom qab ntawd nce qhov kub ntawm 80-85 ° C rau 10 feeb.
Txuas ntxiv mus rau kauj ruam 5 kom txog thaum cov xim xav tau.
Txhawm rau ua kom tiav cov txheej txheem no, tshem tawm cov ntaub los ntawm da dej dyeing, yaug hauv dej sov, tig qhuav thiab hlau.
Thermal hloov siv disperse dyes thiab coatings
Disperse dyes tuaj yeem siv rau hauv kev hloov luam ntawv.Koj tuaj yeem tsim ntau yam luam tawm ntawm cov khoom siv hluavtaws (xws li polyester, nylon, thiab ntaub plaub thiab paj rwb sib xyaw nrog cov ntsiab lus hluavtaws fiber ntau ntau dua 60%).Cov xim ntawm disperse dyes yuav tshwm sim npub, thiab tsuas yog tom qab ua haujlwm los ntawm tshav kub tuaj yeem pom cov xim tiav.Kev kuaj ua ntej cov xim yuav muab qhov qhia tau zoo ntawm qhov kawg tshwm sim.Cov duab ntawm no qhia tau hais tias qhov tshwm sim ntawm kev hloov ntawm paj rwb thiab polyester fabrics.Sampling tseem yuav muab sijhawm rau koj los xyuas cov hlau qhov chaw thiab lub sijhawm xa khoom.
