The influence of hemp fibres in paper on chemical resistance of prints

In the last few years the consumption of non-wood fibres in pulp and paper industry has been showing the increasing trend. Regardless to the fibre origin, it is very important that used fibres provide good quality of the paper and their printability for the final graphic product. The aim of this research was the evaluation of some chemical, optical and surface properties of hemp fibre based papers which were used for making prints. Hemp fibre based papers were printed and the chemical resistance of prints has been analysed. In accordance with ISO 2836:2004 all prints were tested for resistance to water, alcohol and alkali. Evaluation of chemical degradation on prints was determined through the Euclid color difference (Euclid distance of CIE L*a*b* coordinates, ΔE00 value) and surface roughness (Ra value).
