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 dyes, yog li txhim kho kev ntxuav thiab hws ceev, thiab qee zaum txawm tias lub teeb nrawm.
Feem ntau siv kho cov neeg ua haujlwm suav nrog cationic quaternary ammonium ntsev, xws li hexadecylpyridine chloride thiab hexadecylpyridine bromide; amine-formaldehyde resin-hom dicyandiamide-formaldehyde thawj condensates (kho cov neeg ua hauj lwm Y, M); polyamine condensates (txheej kho tus neeg sawv cev LA); phenolic condensates (crosslinking kho tus neeg sawv cev DE); crosslinking kho cov neeg ua haujlwm (Indosol CR); reactive dye fixing agents KS; thiab phenolsulfonic acid-formaldehyde condensates siv los kho cov neeg ua haujlwm hloov tannins ntawm nylon (polyamide) fabrics.
