Tam sim no, lub siab ntawm kev tiv thaiv ib puag ncig yog nce.Nylon filaments txhawb kev tsim khoom huv si, thiab cov txheej txheem xim tsis muaj dej tau nyiam ntau thiab ntau dua.Hauv qab no yog qee qhov kev paub txog cov txheej txheem dej tsis muaj xim.
1. Anhydrous coloring txheej txheem ntawm nylon 6 yarn
Tam sim no, cov xim ntawm thepolyamide filament nyob rau hauv Tuam Tshoj txoj kev lag luam nylon feem ntau yog siv rau dip dyeing thiab ncoo dyeing nyob rau tom qab theem ntawm spinning.Cov dyes siv muaj xws li disperse dyes thiab acid dyes.Txoj kev no tsis yog tsuas yog sib cais los ntawm cov dej, tab sis kuj muaj kev siv zog thiab tus nqi siab.Cov pa phem ntawm kev luam ntawv thiab dyeing dej khib nyiab nyob rau theem tom ntej yog teeb meem heev.
Cov xim yog siv los ua cov xim xim los npaj cov xim masterbatch, uas yog yaj-spun nrog nylon 6 yarn chips kom tau txais cov nylon 6 xov paj xim.Tag nrho cov txheej txheem spinning tsis tas yuav poob dej, thiab nws yog ntsuab thiab ib puag ncig tus phooj ywg.Nws yog cov txheej txheem siv ntau dua uas tau tshwm sim nyob rau xyoo tas los no, tab sis nws tsis zoo tag nrho ntawm kev sib tw thiab qib qib.
Lub tshuab nqus tsev sublimation dye coloring txheej txheem siv disperse dyes los yog yooj yim sublimable pigments li colorants, uas yog sublimated rau hauv roj nyob rau hauv siab kub los yog lub tshuab nqus tsev tej yam kev mob, adsorbed rau saum npoo ntawm nylon 6 yarn filaments thiab diffused mus rau hauv lub fiber kom tiav cov txheej txheem dyeing.
2. Qhov zoo ntawm nylon 6 yarn waterless coloring txheej txheem
Cov txheej txheem no tsis haus dej, tab sis muaj ob peb hom dyes thiab pigments uas tuaj yeem siv rau xim nylon 6 yarn filaments.Kev tswj ntawm sublimation ceev yuav cuam tshuam rau theem thiab dye uptake mus rau ib qho twg, uas yuav tsum muaj cov cuab yeej siv siab.Txawm hais tias tsis muaj teeb meem ntawm dej qias neeg, kev ua qias tuaj rau cov khoom siv, ib puag ncig thiab cov neeg ua haujlwm tsis tuaj yeem tsis quav ntsej.
Supercritical carbon dioxide dyeing tsis haus dej.Hydrophobic disperse dyes tuaj yeem yaj hauv supercritical carbon dioxide rau xim nylon filaments.Piv nrog rau dyeing dej, lub sij hawm dyeing yog luv dua.Tsuas yog los ntawm kev kho lub siab thiab kub, tag nrho cov txheej txheem dyeing tuaj yeem ua tiav ntawm ib lub cuab yeej, tab sis nws tsis tuaj yeem daws cov txiaj ntsig ntawm oligomers ntawm kev ua haujlwm dyeing thaum lub sijhawm dyeing.
