Abstract: The invention relates to a method for the continuous dyeing of warp ends, in particular cotton warp ends, with indigo or other dyestuff groups which, after impregnating and squeezing out, require oxidation or thermal treatment for fixing. The method eliminates the disadvantages of traditional methods for the continuous dyeing of warp ends. In particular, the required bath amount is considerably reduced by this method. By using a new dyeing reactor (1), the residence time of the warp ends in the dyeing installation can be varied without having to increase the bath volume. The option of heating or cooling the dyeing bath enables a fixing temperature between below room temperature and over 100° C. to be chosen. Optimal conditions can thus be created for all dyeing methods which are habitual for warp ends.

Abstract: The invention relates to an installation for the wet and/or dry treatment, such as washing, dyeing, bleaching, steaming, drying, finishing and/or sizing of a web, yarn, strand or filiform textile goods with a carrier supporting the textile goods, consisting of several rollers, on which the textile goods are guided as an endlessly running band and with at least one or several treatment unit(s), wherein the carrier with the textile goods can travel in any desired succession. The dimensions of the rollers basically correspond to the ones of rollers in industrial installations, but can be reduced when the installation has to operate under lab-test conditions. Compared to industrial installations, this installation has an extremely compact construction.

Abstract: A dyeing padder for the dyeing of warp yarn includes a dyeing vat having at least two sectional and mutually connected vat chambers both used in a dyeing process with indigo dyes or alternatively, only one of the sectional vats is used, a displacement body introduced in the dyeing vats for reducing a volume of a dye bath having a continuous circulation thereof at a constant level.

Abstract: A process for the treatment of warp yarns as a row of substantially parallel threads, wherein said yarns are impregnated with excess treating liquor, said excess is removed from the yarns and the treated yarns are finally dried and wound up on a loom beam, the improvement of bringing the linear thread density of the yarns, at least in the excess liquor removal zone, to a value of 2 or higher, said value being the same over the entire width of said yarn row, and reducing said yarn density to the nominal thread count for weaving before said yarns are wound up on at least one loom beam.
