<p>Large amounts of water, synthetic dyestuffs and chemicals are used in the wet processes of</p><p>textile finishing, and at the end of these processes, liquors containing chemical substances create a</p><p>waste load. For this reason, it is of great importance to develop new wet-finishing processes that use</p><p>less water, dyestuffs and chemicals. For this purpose, the layer-by-layer deposition method (LbL)</p><p>was used in this research as an environmentally friendly, sustainable method that can be used in wetfinishing processes to minimize chemical, water and energy consumption. The dyeing and functional</p><p>finishing of cotton fabrics were carried out in one process by the LbL method. Cotton fabrics were</p><p>pre-treated with a commercial cationic dye fixation agent and cationic charges were produced on</p><p>the fabric surfaces. Reactive and direct dyestuff groups were used in the dyeing process of cotton</p><p>fabrics and fluorocarbon was used in the functional finishing process. Eight and 12 dye/fluorocarbon</p><p>layered structures were obtained by LbL deposition using a laboratory-type padder. Cotton fabrics</p><p>were dyed and finished with the same dyes and fluorocarbon via the padding method and both</p><p>samples were compared. The washing, rubbing and light color fastness properties, color strength</p><p>and color difference of the dyed samples were tested. Tensile strength, air permeability, SEM graphs,</p><p>contact angle, water and oil repellency analyses were performed for the treated fabrics.</p><div><br></div> |
