small amount of dmdheu was added more decreases in fabric tensile strength along both warp and weft directions were observed table 2 results on fabric hand table 1 showed that the latex finish could increased the values of fabric bending rigidity b and hysteresis of bending moment 2hb in both machine warp and cross weft directions depending on the core flexibility and the padding solution with or without a crosslinker the increase in fabric stiffness was quite different while fabrics became much stiffer after finishing with the hardcore cts pnipam latexes the soft cts pba treated cotton had relatively small changes in both bending rigidity and bending hysteresis moreover we found that the cts pba padded sample had a better fabric hand than the fabric padded from 0 5 wt chitosan solutions table 1 in this procedure sample fabrics 1 u00b1 0 1 g cut into around 0 5 u00d7 0 5 cm were dipped into a test flask containing 50 ml of 0 5 mm pbs monopotassium phosphate culture solution with a s aureus atcc 6538 cell concentration of 1 0 1 5 u00d7 10 4 ml the flask was then shaken at 250 rpm on a rotary shaker at 37 u00b0 c for 1 h before and after the shaking 1 ml of the test solution was extracted diluted and spread onto an agar plate after 24 h of incubation at 37 u00b0 c the number of colonies formed on the agar broth was counted and the number of bacterial cells a or b in the testing flask was calculated fig7 amp 8 are the results of antibacterial tests on cotton fabrics before and after the treatment besides cotton antibacterial test on other modified textiles is summarized in.
