Analysis of breakage of the polymer layer in the conditions of use and care of digitally printed textile products

The causes of breakage and damage of digital inkjet prints are analyzed from the aspect of the cotton fabric surface structural characteristics, physical parameters and the amount of pigment defined by the color characteristic, the method of pretreatment and in real conditions of use and care of a final product. After analyzing the physical and mechanical properties of the textile material, the non coated samples and samples coated by acrylate-based binder, were digitally printed by inkjet technology. The printed samples were analyzed by spectrophotometric measurements, and in terms of the surface morphology by microscopic imaging with a Dino - Lite digital microscope. A test of fastness to different washing conditions was performed and the results are presented in terms of total color difference calculated based on the CIE76 formula, by comparing samples before and after washing. The research was performed in order to solve the real problem of the stability of digital prints in the conditions of care, in cooperation with the company Moira, Nova Gradiška.
