Interaction of colour and cotton fabric surface coated with ultrafine cellulose (UFC)

In this research the influence of ultrafine cellulose (UFC) coating of cotton fabric, on the colour characteristics of a digitally printed sample was tested. Three pastes with a difference in the amount of binder and crosslinking agent were applied in the layering process. Coated cotton surfaces were digitally printed in a multicolour pattern. The synergy of the two layers (ultra-fine cellulose and pigment layer) was analysed in terms of colouristic, fastness and chemical-physical properties. Wet rubbing resistance of layered surface before printing and washing resistance of layered surface after printing were tested. The morphology of surface structure of the samples was analysed by using FESEM (Field Emission - Scanning Electron Microscope). Coloristic parameters were analysed by numerical evaluation and graphical representation of CIELAB colouristic values as well as in terms of CIE colour differences.
