Daim ntawv thov ntawm Dispersed zas xim leveling tus neeg sawv cev hauv Dyeing thiab Polyester

Qhov kev ua phem tsuas yog siv rau dyeing hydrophobic fibers xws li polyester, spandex, thiab acetate fibers. Nrog kev nce qib nruam ntawm fiber dyeing thev naus laus zis, ntau hom kev sawv cev theem tau ua tiav.

1, tus neeg sawv cev theem rau kev kub siab-kub

Thaum siv cov dyes dispersed rau high-kub siab, tsis sib xws yog feem ntau tshwm sim los ntawm cov xim tsis zoo, thiab hloov chaw tswj ntawm cov khoom siv cua sov. Tshwj xeeb tshaj yog rau cov polyester nplua, cov kab ntas ntom ntom yog qhov tsawg heev, thaj chaw nce, thiab qhov nrawm ntawm dyes accelerates. Ib qho ntxiv, cov qauv ntaub npuag nruj ua rau nws nyuaj rau kev nkag mus rau qhov nkag mus, ua rau muaj peev xwm ua tau qhov tsis zoo tshaj li cov pa polyester. Kev siv ntawm kev kub-dispersing leveling cov neeg sawv cev thaum lub sij hawm ziab tuaj yeem txhim kho cov nyhuv ntawm cov xas thiab txhim kho cov khoom lag luam zoo.

Feem ntau, tsis yog-ionic surfactants tuaj yeem siv los ua cov neeg sawv cev qib nyiaj, uas tuaj yeem tsim cov khoom siv hydroting kom ua tiav qib. Ntawm cov neeg sawv cev tsis muaj iionic dispersing, polyoxyylene Ester cov qauv muaj txiaj ntsig zoo dua rau kev ua tau zoo dua (Ester rings muaj kev ua tau zoo dua li rog.

Txawm li cas los xij, tsis yog-ionic surfactants yog nquag ua kom lub cev tsis muaj txiaj ntsig, thiab tsis muaj ionfing ntawm ethester rog thiab kev tsis txaus siab thiab tsis zoo thiab tsis zoo. Thaum siv cov huab uas tsis muaj huab tsis yog-ionic surfactants, zas kev sib sau ua ke yog muaj tshwm sim. Vim yog cov muaj zog tsis zoo them txheej txheej tsim los ntawm anionic surfactants ntawm lub xeev dauv tawg, muaj lub zog hluav taws xob tsis sib xws thiab ua kom cov zas nyob ruaj khov hauv cov kua zas. Qhov no tuaj yeem daws qhov teeb meem ntawm cov xim zas xim tshwm sim los ntawm cov huab tsis muaj huab ntawm cov tsis muaj txiaj ntsig.

Lub siab ua haujlwm siab qhov kev saib xyuas kub yog tsim los ntawm kev siv cov kev ua haujlwm thiab anionic surfactans, qhov twg cov qauv sib txawv ntawm txhua yam muaj cov teebmeem sib txawv. Muaj ntau ntau qhov kev kub siab rau cov neeg sawv cev (ib co uas tseem suav nrog qee cov nqa khoom) tsim nrog cov khoom siv anionic / tsis muaj kev ntseeg. Cov qauv sib txawv ntawm txhua cov khoom sib txawv muaj cov haujlwm sib txawv, feem ntau muab faib ua: 1) Kev coj ua kom zas, thiab qeeb thaum lub sijhawm zas; 2) Thaum lub qhov kub tshaj plaws mus txog tus nqi tseem ceeb, txo cov ntxig thiab kev ua kom muaj qhov txias thiab tso rau cov iav hloov pauv hauv qab. Nyob rau tib lub sijhawm, lawv tuaj yeem ua raws li cov kuab tshuaj rau kev ua kom tsis tu ncua desorb thiab tshem tawm cov fibers, ua rau muaj qhov txias loj (hloov chaw zas ntsej muag) kom ua tiav qhov ua zas xim txawv.

Qee cov khoom lag luam ntawm cov khoom muaj zog muaj kev ua npuas dej siab, uas tuaj yeem yooj yim ua rau muaj teeb meem hauv cov tshuab dowying ceev. Yog li ntawd, cov foaming foaming leveling cov neeg sawv cev yuav tsum tau ua. Kev daws yog ntxiv defoamers, tshwj xeeb yog orgososilicon defoamers, uas muaj txiaj ntsig zoo ntawm qhov kub; Cov khoom siv npuas dej tsawg yog tau los ntawm copolymerizing ethylene oxide thiab propylene oxide.
