Kev siv cov tshuaj disperse dye leveling agents hauv polyester dyeing

Cov xim disperse feem ntau yog siv rau kev zas xim hydrophobic fibers xws li polyester, spandex, nylon, thiab acetate fibers. Nrog rau kev nce qib tas mus li ntawm cov thev naus laus zis dyeing fiber, ntau hom leveling agents tau ua tiav kev loj hlob tseem ceeb.

1. Tus neeg sawv cev rau kev zas xim kub siab

Thaum siv cov xim disperse rau kev zas xim kub thiab siab, kev zas xim tsis sib xws feem ntau tshwm sim vim yog cov yam xws li kev sib kis tsis zoo, kev sib npaug, thiab kev txav mus los ntawm cov xim, nrog rau kev tswj hwm qhov kub tsis zoo. Tshwj xeeb, cov polyester fibers zoo-denier muaj qhov ceev me me thiab thaj chaw ntau dua, uas ua rau qhov nrawm ntawm cov xim zas xim sai dua. Tsis tas li ntawd, cov qauv ntaub nruj ua rau nws nyuaj rau cov xim nkag mus rau hauv, ua rau muaj kev zas xim tsis sib xws ntau dua piv rau cov polyester fibers ib txwm muaj. Kev siv cov neeg sawv cev sib npaug kub thaum lub sijhawm zas xim tuaj yeem txhim kho qhov cuam tshuam ntawm cov ntaub thiab txhim kho cov khoom zoo.

Feem ntau, rau cov xim tsis-ionic disperse, cov surfactants tsis-ionic tuaj yeem siv ua cov neeg sawv cev leveling. Ob qho tib si tuaj yeem tsim cov hydrophobic ua ke, uas tuaj yeem qeeb qeeb qhov nrawm dyeing kom ua tiav lub hom phiaj ntawm leveling. Ntawm cov molecules ntawm cov neeg sawv cev leveling uas tsis-ionic dispersing, polyoxyethylene ester-hom surfactants muaj cov khoom zoo dua li polyoxyethylene ether-hom surfactants (qhov sib raug zoo ntawm cov qauv ester-hom rau polyester yog ntau dua li ntawm cov qauv ether-hom), thiab surfactants nrog benzene rings muaj cov khoom zoo dua li aliphatic surfactants.

Txawm li cas los xij, cov tshuaj surfactants uas tsis yog ionic feem ntau yuav qhuav thaum lub sijhawm kub siab ntawm polyester, thiab kev sib xyaw ua ke ntawm cov saw hlau oxyethylene thiab cov pab pawg xws li hydroxyl thiab amino hauv cov xim pleev xim yog qhov kev nqus dej xoob, tsis muaj zog intermolecular, ua rau tsis muaj kev sib kis thiab solubilization. Kev siv cov surfactants uas tsis yog ionic qis-huab tuaj yeem ua rau cov xim sib sau ua ke. Txij li thaum anionic surfactants tuaj yeem raug adsorbed rau ntawm qhov chaw ntawm cov xim pleev xim los tsim cov txheej txheem them tsis zoo, muaj kev tawm tsam hluav taws xob muaj zog ntawm cov xim pleev xim, tsim kom muaj lub xeev sib cais ruaj khov. Lawv muaj peev xwm sib kis tau zoo rau cov polymers sib koom ua ke ntawm cov xim pleev xim, yog li txo lawv cov kev sib sau ua ke thiab ua kom cov xim pleev xim ruaj khov hauv chav dej xim pleev xim, uas tuaj yeem daws qhov teeb meem ntawm cov xim pleev xim los ntawm kev sib sau ua ke vim yog qhov qis huab ntawm cov surfactants uas tsis yog ionic.

Cov neeg sawv cev kub siab uas muaj kev ua tau zoo heev yog ua los ntawm kev siv cov teebmeem synergistic thiab txhim kho ntawm cov surfactants tsis-ionic thiab anionic surfactants, qhov twg cov qauv sib txawv ntawm txhua qhov khoom muaj cov haujlwm sib txawv. Muaj ntau cov khoom siv kub siab uas tau sib xyaw los ntawm anionic / non-ionic surfactants (qee qhov kuj ntxiv qee qhov nqa khoom). Cov qauv sib txawv ntawm txhua qhov khoom muaj cov haujlwm sib txawv, uas tuaj yeem faib ua: 1) Cov qauv ethoxy tuaj yeem ntes cov xim disperse thaum lub sijhawm dyeing, nce qhov chaw dyeing ntawm cov xim, thiab ncua dyeing; 2) Thaum qhov kub dyeing ncav cuag qee qhov tseem ceeb, cov qauv aromatic compound tuaj yeem ua rau cov polyester fiber sai sai plasticize thiab o, txo qhov kub hloov iav ntawm polyester los ntawm 20-25, ua rau cov qhov hws hauv cov fiber ntau ntxiv, ua rau cov xim zas sai thiab sib zog zas cov fiber, thiab tib lub sijhawm, ua haujlwm ua cov kuab tshuaj rau cov xim zas kom cov xim zas hauv cov fiber txuas ntxiv desorb los ntawm cov fiber thiab dhau los ua qhov pom tseeb (kev tsiv teb tsaws chaw) kom ua tiav cov txiaj ntsig leveling.

Qee cov khoom sib xyaw ua ke ntawm cov surfactants muaj cov khoom ua npuas siab, uas tuaj yeem ua rau muaj teeb meem hauv cov tshuab zas xim sai thiab cov xim zas xim qis. Yog li ntawd, cov neeg sawv cev ua npuas qis yog qhov yuav tsum tau ua. Cov kev daws teeb meem suav nrog: ntxiv cov tshuaj defoamers, tshwj xeeb tshaj yog silicone defoamers, uas ua haujlwm zoo heev ntawm qhov kub siab; siv txoj kev copolymerization ntawm ethylene oxide thiab propylene oxide kom tau txais cov khoom ua npuas qis.

2. Tus neeg sawv cev rau kev zas xim thermosol

Thaum lub sijhawm ua cov txheej txheem thermosol dyeing ntawm cov xim disperse, kev tsiv teb tsaws chaw feem ntau tshwm sim, ua rau muaj qhov tsis zoo xws li cov xim me me, cov duab ntxoov tsis sib xws, thiab cov kab ntawm cov ntaub, ua rau cov xim tsis sib xws. Txhawm rau daws qhov teeb meem no, yuav tsum siv cov tshuaj tiv thaiv kev tsiv teb tsaws chaw. Tam sim no, muaj ob hom tshuaj tiv thaiv kev tsiv teb tsaws chaw hauv daim ntawv thov: ib qho yog sodium alginate; lwm qhov yog acrylic copolymer. Sodium alginate muaj cov yam ntxwv tsis zoo ntawm kev zas xim, thaum acrylic copolymer muaj peev xwm tiv thaiv kev tsiv teb tsaws chaw zoo thiab tsis muaj qhov tsis zoo ntawm kev zas xim.
