Adding antibacterial properties to textile materials containing polyester fibers during dyeing stage

The work investigated the possibility of combining the antibacterial treatment with the process of dyeing fabrics, containing polyester fibers, using triclosan. A feature of the chosen biocide is its ability to plasticize the polyester structure and facilitate dye diffusion, which will allow to lower the dyeing temperature of 30-40 °C (to 100 °C) or at high temperature dyeing decrease the consumption of the dye due to its greater selectability. It is shown that by using the triclosan color intensity increases while color stability persists. The fact of obtaining antibacterial properties is proved. Triclosan can not only provide a reduction in energy consumption during dyeing but also eliminate the antibacterial treatment at final finishing step. It can be recommended for the dyeing of fabrics that contain polyester fibers.
