New quaternary ammonium compounds, 6-(1- anthraquinonylamino) hexyldi methylammonium bromide (AHDAB) was synthesized by 1- aminoanthraquinone with dimethyl dodecyl amine via hexamethylene spacer, and their antimicrobial activity was investigated. Results indicate that the new quaternary ammonium salt was successfully treated on Nylon surfaces by exhaustion method as in dyeing, and durable antimicrobial finish of Nylon was also investigated. New QAC was exhausted on Nylon fabric without any aid of chemical auxiliary even that is watersoluble. Since AHDDAB is soluble in water, and the anthraquinonyl moiety of compound could anchor on Nylon surface, and the antimicrobial part orientates outwards, the results indicate that the durability of Nylon treated with AHDAB were good enough as to maintain the initial properties even after 25 repeated laundering. The fastness of Nylon treated with AHDAB to 25 repeated laundering in anionic commercial detergent are good enough to show colony reduction above 65% against S, aureus and K, pneumoniae. The results mentioned above would suggest that test fabrics finished with AHDAB could be valuable to the development of the field of antimicrobial fabrics, and could contribute considerably to the greater hygiene of all textiles in general.
