AB - New quaternary ammonium compound, 6-(1-anthraquinonylamino) hexyldi methylammonium 
bromide (AHDDAB) was synthesized by 1-aminoanthraquinone with dimethyl dodecyl amine via 
hexamethylene spacer, 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 though it is 
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 was good enough to maintain the initial properties 
even after 30 repeated launderings. The fastness of PET treated with AHDDAB after 30 repeated 
launderings in anionic commercial detergent is 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 better hygiene of all textiles in general.
