The paper presents research on the application of vat dyes to inherently flame resistant fabrics, using the conventional screen-printing method. The composition of the fabrics are defined within a scope of a project conducted in partnership of Croatian textile factory Cateks d.d. and University of Zagreb Faculty of Textile Technology. Fabrics are screen printed by using a vat dye Indanthren® Olive R (DyeStar, Germany) in two concentrations. After printing, a coloristic analysis of the obtained colouration is performed, based on instrumental spectrophotometric measurement and objective evaluation of the colouristic parameters (L*, C*, h°) and colour depth (K/S). The samples are tested for resistance to surface burning, and the colour fastness to dry/wet rubbing and light exposure are also tested. Excellent results of fire resistance and dry/wet rubbing resistance are achieved, while resistance to light exposure is lower to optimal. |
