nm on cotton and 600 nm on polyester this could be explained as due to the difference in the chemical structure of the fabrics the drug coated fabrics are therefore suggested to be used as antibacterial fabrics the drug coated bandages revealed an antibacterial activity stronger than that of a commercial ttcl tablet the pms can be used to improve dye affinity fabrics coated with pristing pms were dyed and washed under the usual testing conditions in a rotawash machine 60 min 40 u00b0 c 40 rpm in order to determine the effect of the proteinaceous microspheres on dye affinity the results show that proteinaceous microspheres bound to cotton or polyester increased dye affinity especially for acid dyes such as coomassie brilliant blue g the gluteraldehyde ga cross linked microspheres bound to fabrics showed an increase in the dye affinity as compared to pm coated fabrics without ga this results from a better protein fixation on the fabrics 39 surfaces when ga is used proteinaceous microspheres on the fabrics were measured by the modified lowry method indigo backstaining during cellulase washing cavaco paulo a morgado j almeida l kilburn d textile res j 1998 68 398 401 the results of the k s values color staining levels at 620 nm are presented in fig1 the stability of bonded spheres under ambient conditions of using and wearing the textiles was measured by using dyeing and washing under tests modified lowry method by this technique we have measured the bond strength between.
