<p>The hanks are laid on a material bearing arm (A) inserted on a mobile wall (P) which acts as a proof closing door of the dyeing tank. At its end the arm is properly conceived for being introduced into a motor lodging on the opposite side, on the moving wall, in the dyeing tank. By means of this contrivance, the arm is motorized and, therefore, kept in constant rotating motion both in clockwise and anticlockwise sense in order to avoid entanglement of the hanks. The dyeing bath is constantly injected and recirculated on the hanks which are kept in continuous motion by means of a system of pump (D) and bored injection pipes (B). This double aspect, continuous injection and rotation, allows a very quick renewal of the dye molecule contact dissolved in the solution of the dyeing tank with the textile material and their respective hooking power. Therefore, by increasing the contacts of the dyeing substance with the textile material, the temperature increasing time can be reduced which is indispensable for the colour fixing with a consequent considerable reduction of the dyeing times.</p> |
