Cationic xim av dyes
Cationic dyes yog ib hom ntawm textile dyes, tseem hu ua alkaline dyestuff thiab puag. Lawv yog cov soluble hauv dej thiab ionized hauv cov kua aqueous los ua cov xim zoo sib xyaw ions. Cov ntawv caws ntawm cov xim zas tuaj yeem ua ke nrog cov kua qaub pawg ntawm tus thib peb cov monomer hauv cov ntaub los ua cov tshuaj fibering.
Cov khoom yog xim tshwj xeeb ntawm acrylonitrile fiber. Cov txheej txheem dyeing nyob hauv lub dab da dej uas tsis muaj zog acidity (tus nqi pH yog txog 4. Cov. Cov txheej txheem dyeing tuaj yeem faib ua peb qib:
(1) Lub cation hauv da dej dyeing yog adsorbed rau ntawm cov npoo.
(2) Cov cation sib txawv ntawm qhov xov paj mus rau sab hauv.
(3) Lub cation yog ntsev-sib raug zoo nrog cov anion pawg uas muaj nyob hauv cov fiber.
