Fixation of Cationic Antibacterial Products Before Dyeing: A More Ecological Process

ABSTRACT With the vulgarization of antimicrobial treatment of textile fabrics, simple methods to quantify the evaluated the link efficacy, and durability performance will be needed. The biological tests are usually inexistent in textile plant and their specific requisites allow that need to be made by controlled biological laboratories out of textile facilities. The knowledge of textile dyeing processes was applied to the control of cationic antimicrobial applications. The exhaustion profile of a direct dye with lower affinity was used to evaluate the concentration of bonded cationic antimicrobial agent on cotton material. Only bonded agent lasted throughout the dyeing process, transforming this process as a quick simultaneous evaluation of the nature of the bond between agent and fibre.
