Utilization of Magnetic Fields during Coloring of Cellulose and Polyester Fiber Fabrics.

摘要

The intensification of the processes of coloring textile materials with the utilization of magnetic fields is executed by the magnetic treatment of industrial water or dye solution. Magnetization of water during coloring of cotton fabric by direct dyes accomplished on the type PMU-1 apparatus with circular permanent magnets with laminar nature of flow, close to the transitional into the turbulent, and the strength of the magnetic field in the primary operating gap of the apparatus 143 kA/m. The most effective variant of magnetic activation of the impregnation process of cellulose and polyester fabrics with solutions of active and disperse colorants with their subsequent thermal fixation on textile material is revealed.
