Abstract: An apparatus for mercerizing textiles and fabrics of cotton or cotton blends; the textile material, before and during impregnation with lye, is guided between a drum mantle and a synchronous liquid-permeable pressure band; removal of the lye is effected through the textile material while the latter is looped around the drum. The shrinkage of edges, especially of fabrics, is to be avoided both with certainty and also in a lasting manner. Also to be achieved is a complete impregnation of the textile material, as well as a removal and recovery of the strong lye without a dilution thereof by weak lye or water used for removal of lye.

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.
