Kev kho cov neeg ua haujlwm yog cov pabcuam tseem ceeb hauv kev lag luam luam ntawv thiab dyeing. Lawv yog siv los txhim kho cov xim ceev ntawm dyes ntawm fabrics thaum kho ntub dej. Ntawm cov ntaub, lawv tuaj yeem tsim cov xim tsis sib haum nrog cov xim, yog li txhim kho cov xim nrawm rau kev ntxuav thiab hws, thiab qee zaum txawm tias txhim kho nws lub teeb nrawm.
Cationic surfactant quaternary ammonium ntsev kho cov neeg ua haujlwm ua haujlwm los ntawm kev sib txuas cationic quaternary ammonium ntsev nrog sulfonic acid anions ntawm cov xim tom qab dyeing nrog dej -soluble anionic dyes. Qhov no electrostatic attraction ntawm qhov zoo thiab tsis zoo nqi tsim ib tug dej- pas dej insoluble, yog li ua tiav xim ceev thiab txhim kho xim ceev, tshwj xeeb tshaj yog ntxuav ceev.
