ABSTRACT:
A method for continuously treating strand-like textile material which is transported horizontally in vertical loops, by way of transverse rods or bars, through a treatment liquid, particularly a hot mixture of liquids; the formation of the loops occurs by way of vertical flow. The loop formation, the maintaining of the formed loop, the form or shape stability thereof, as well as the horizontal movement thereof are effected by transverse rods or bars, which are arranged in the lower loop bends and in the vicinity of the container bottom move from the textile strand inlet or entry side of the textile strand outlet or discharge side, and by a flow directed upwardly between the transverse rods or bars; the horizontal movement is aided by a horizontal transverse flow of the treatment liquid. The apparatus for carrying out the foregoing method includes a cubic or quadratic liquid container, and an endless chain which is guided in the vicinity of the container bottom and the container end walls and is provided with transverse rods or bars of greater width than that of the textile strand to be treated. The apparatus further includes an air permeable and liquid permeable stationary support or overlay which is inclined relative to the horizontal from the textile strand inlet or entry side to the textile strand outlet or discharge side of the container. The apparatus also includes a pair of rails in the vicinity of the container bottom for the transverse rods or bars, of the endless chain, moved thereon, and upwardly directed nozzles located below the support or overlay as well as a device for generating the transverse flow.
