Sažetak

Due to increasing environmental awareness and the need to apply the circular economy, natural dyes are increasingly used in the textile sector. In this research, pigment printing is carried out with natural plant dyes, i.e. plant extracts from walnut leaves, pomegranate peels and onion peel. The composition of the printing paste and the fixation parameters are optimised. A print screen is created to assess the quality of the print, focussing on the sharpness of the print. Pastes with Prisulon DCA 90 or Tubivis Star, a universal thickening agent for textile printing, were compared without and with the addition of aluminium salt. A launder and rub resistance test were carried out on printed cotton fabrics. The results were analysed spectrophotometrically using a Datacolor 850 spectrophotometer. It was found that fixing the printed textile fabric with a paste containing the thickening agent Prisulon DCA 90 with aluminium salts and natural plant dye for 240 seconds at 180°C led to the best results in terms of wash and rub resistance. The natural dyes and their concentrations are selected according to the design idea with a view to the desired implementation in the textile design on the final product.
