(1) Cov disperse dye yuav tsum siv dej hauv qab 40 ° C thaum muab faib thiab yaj. Vim hais tias cov disperse dye manufacturing txheej txheem tau ntxiv ib tug loj npaum li cas ntawm dispersant, xws li ntau kub dispersing tus neeg sawv cev, lub disperse dye yog agglomerated. Dissolving yog qhov nyuaj tshaj. Yog tias lub lim tsis huv, nws yooj yim los tsim cov xim ntsiab lus.
(2) Disperse dyes yog prone rau heev nyob rau hauv qhov muaj hlau ions. Yog li ntawd, nws tsis yog siv tau los siv cov xim hauv cov xim ntawm cov xim xim, thiab sodium hexametaphosphate softener yuav tsum ntxiv.
(3) Cov disperse dye tseem nyob ruaj khov hauv qaub tsis muaj acidity, thiab alkaline kua nyhav ua lub disperse dye rau hydrolyze los cuam tshuam cov xim lub teeb. Feem ntau, cov pH tswj tau nyob hauv qhov ntau ntawm 5 txog 5.5. Yog tias tus pH qis dua 8 lossis siab tshaj 10, qhov qis ntawm cov roj pleev muaj qis qis, uas ua rau muaj cov hlwv ntawm cov paj rwb. Lactic acid los yog tartaric acid tej zaum yuav muab ntxiv rau qhov muab tshuaj txhuam los kho tus pH.
(4) Cov tshuaj ntsuab thawj coj yuav tsum siv cov thev nchuav thiab sodium alginate paste uas nyob ruaj hauv qaub qaug zog. Yuav kom txhim kho cov nyhuv xim ntawm cov xim xim tshuaj, cov emulsified paste yuav muab ntxiv rau tib lub sijhawm, tab sis nws yuav tsum tsis txhob ntau heev, txwv tsis pub tus contour ntawm tus qauv yuav raug cuam tshuam.
(5) Tsis muaj urea ntxiv tsuas yog ntshiab polyester ntaub luam ntawv. Txwv tsis pub, tus qauv ntawm cov paj rwb fiber ntau dua. Vim muaj kev kho mob siab, tua cov dej, volatilizes thiab decomposes ntawm 130 ° C, thiab cov ntaub ntawv eutectic nrog cov disperse dye, uas ua rau cov tawv tsis ntxuav tawm.
