Abstract New quaternary ammonium compounds, 6-(1-anthraquinonylamino) hexyldi methylammonium bromide (AHDDAB) was synthesized by 1-aminoanthraquinone with dimethyl dodecyl amine via hexamethylene spacer, and its antimicrobial activity was investigated. Results indicate that the new quaternary ammonium salt was successfully treated on PET surfaces by exhaustion method as in dyeing, and durable antimicrobial finish of PET was also investigated. New QAC was exhausted on PET fabric without any aid of chemical auxiliary even water- soluble. Since AHDDAB is soluble in water, and the anthraquinonyl moiety of compound could anchor on PET surface, and the antimicrobial part orientates outwards, the results indicate that the durability of PET treated with AHDDAB were good enough to maintain the initial properties even after 30 repeated laundering. The fastness of PET treated with AHDDAB to 30 repeated laundering in anionic commercial detergent are good enough to show colony reduction above 70% against S, aureus and K, pneumoniae. The results mentioned above would suggest that test fabrics finished with AHDDAB could be valuable in the development of the field of antimicrobial fabrics, and could contribute considerably to the better hygiene of all textiles in general.
