Abstract: In a washing method, a web of textile goods is wetted with a washing-active liquid and the liquid is caused to foam by steam which is blown at high pressure into a back side of the web of goods with a pile on the front side. The steam is discharged from a nozzle slot that extends transversely across the web of goods. The nozzle directs the steam against the web and through it. The foam which then suddenly forms is then drawn off by a vacuum or suction together with the liquid still in the pile from the pile side of the web.

Abstract: A method wherein a thin card web which contains meltable synthetic fibers as well as natural fibers is processed into a thicker web of fleece. The synthetic fibers are initially melted to prestrengthen the web. Then the web is saturated with the appropriate fluid finishing agent for making the web flame-resistant and the like and this web can then be readily dried on a screen drum dryer. It is at this point that the web layers are accumulated into a proper fleece in a cross layer unit which transfer the end product to a heat treatment assembly for heating to effect vulcanization, curing or setting of the synthetic fibers.

Abstract: The process for rendering wool sliver shrinkproof involves complete wetting of at least one laterally unguided wool sliver with a chlorinating liquor at ambient temperature wherein the liquor is applied to the sliver with a four- to sevenfold excess. The sliver is conducted immediately thereafter through a guide slot, together with the applied excess quantity of liquid; the complete wetting of the fibers of the sliver with the chlorinating liquor is effected in this guide slot by separating the wool sliver from possible air occlusions. Subsequently thereto, the sliver is accompanied by the liquor through a small-volume guide channel, to be squeezed out following the chlorine treatment. The apparatus has a pair of squeeze rolls, the cylinders of which are arranged to be spaced apart to form a guide slot and are rotatably mounted, these squeeze rolls being associated immediately thereabove with spray means to supply the chlorinating liquor necessary for complete wetting.
