Theoretical and practical aspects of original technologies of gray linen finishing

Resumo

Research results on the development of preparation and printing technologies for textile materials containing gray linen fibers were reported. The difficulty of finishing treatment of such fabrics consists in the need to preserve the self-color of flax while obtaining pure color patterns. This problem can be solved through the use of plasma-chemical processes in the preparation stage for imparting high hydrophilic properties to the fabric without affecting the chromophore structure of the natural dye of flax. Technologies for obtaining white and color patterns on self-colored silvery gray flax linen by oxidizing discharge printing were proposed. The influence of the process parameters (oxidant and dye concentrations and steaming temperature and time) on the resulting coloristic effect was evaluated.
