Bu galigmada, akrilik lifi boyamasinda kullanilan katyonik boyarmaddelerden, Synacryl Red X-5GN, Synacryl Magenta ve Synacryl Black X-FBL olrnak iizere, iig farkli katyonik boyarmaddenin antibakteriyel ozellikleri incelenmigtir. 1nsan sajjlijji agismdan zararli olan beg ayn bakteri tiirii; Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa ve Proteus mirablis, % 1, % 2 ve % 5 lik boya konsantrasyonlmnda nasil aktivite gosterdijji, agar difiizyon yontemi ile belirlenmigtir. Elde edilen etki gap1 sonuglanna gore, her iig boyanlnda segilen mikroplara kargi farkli seviyelerde antibakteriyel etkiye sahiptir. 

In this study, cationic dyes used in dyeing of acrylic fiber, Synacryl Red X-SGN, Synacryl Magenta, and Synacryl Black X-FBL were examined properties of antibacterial activity. Five different species of bacteria which are harmful for human health were determined; Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, and Proteus mirablis, how activity on 1 %, 2 %, and % 5 selected dye concentrations. According to the zone of inhibition experimental results, each of tested dye have antimicrobial effect against selected microbes
