Several polyoxyethylene type quaternary ammonium salt cationic surfactants were selected to investigate their interaction with acid dyes and influence on the dyeing properties.

Alkylphenol ethoxylates(APEO) are a kind of non-ion surfactants used widely, which are potential hazardous to environment because of its toxicity, non-biodegradation and biodegradable products.

Nonionics include polyoxyethylene condensates, sucrose esters and alkyl amine oxides.
