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