  • Patent number: 4451263
    Abstract: The very economical padding methods for applying liquid treatment agents and which have largely become established for flat-lying material are also interesting for dyeing and finishing tubular textile material. In the latter case, the use of this technique is however opposed by the finding that on impregnating circular-knitted goods on a pad mangle the squeeze edges are marked on both sides of the tube, which gives rise, for example, to undesirable color differences. According to the invention, this adverse phenomenon and the problems arising therefrom can be avoided if, through maintaining a relatively high liquor pick-up by the textile material and through mechanical shifting of the edges, the liquor is enabled to level out any unevenness produced on squeezing.
