Abstract: Process and apparatus for the continuous, tensionless treatment of textile material lengths and similar web-shaped flat materials wherein the material is conveyed in gathered form to at least one treatment zone of a material treating unit. A fluid stream impinges intermittently from below upon the length of material approximately at right angles to the conveying direction thereby straightening and compressing the material by an alternating lifting and falling of the material. An air permeable conveyor belt may be employed to convey the length of material through the treating units or a number of spaced individual rollers may be provided in the treating unit with the material forming a loop between adjacent rollers which loop is acted upon by the stream of fluid. A sensor arrangement is provided for determining and controlling the length of the loop so as to maintain such length within predetermined limits.

Abstract: The disclosure is directed to a system for the recovery of spent ammonia, in connection with the processing of fabrics and the like with liquid ammonia, and concerns particularly the elimination from the recovered ammonia of undesired water.Economic processing of fabrics by liquid ammonia requires recovery and reuse of substantial quantities of ammonia. In the course of processing, the ammonia unavoidably becomes contaminated with water. Separation of water from ammonia on a laboratory level or, in any kind of batch processing is a theoretically simple matter and can be coped with by conventional differential evaporation techniques, or otherwise. However, in a continuously operating processing line where large quantities of anhydrous liquid ammonia are being used as the treating medium, water accumulates rapidly, not only from the fabric being processed, but also from a certain inevitable amount of air leakage in the system.

The flow of liquid takes place uniformly over the supporting surface of the conveyor support.

Abstract: A method for treating a knitted fabric containing cotton fibers with an alkali hydroxide, which comprises impregnating said fabric with an aqueous solution of an alkali hydroxide while continuously feeding it in the open form in the longitudinal direction, allowing the fabric to shrink in the longitudinal direction, then feeding it to a tenter while giving an overfeed, thereby to hold it to a given width, and then washing the fabric. The knitted cotton fabrics so treated have superior dimensional stability, especially dimensional stability in the widthwise direction, a deep silky luster, a soft bulky hand, and a superior dyeability.

Abstract: Process for continuous wet treatment of elongated materials, such as travelling textile webs and the like, namely for soaking the webs with liquids, applying chemicals thereto, dyeing, washing and rinsing them. The web is passed through a closed space, preferably in an upward direction, between two rows of vertically spaced-apart rollers. The travelling web is subjected to a short-duration action of a hot liquid in at least two separate, consecutive stages which can be in the form of dish-shaped containers that hold the liquid underneath some of the rollers; the web is also subjected to intensive heat treatment in a hot gaseous medium for a longer time than the liquid exposure; and the liquid adhering to the travelling web is squeezed out between at least two consecutive liquid stages, and preferably returned to a container of a stage through which the web was previously guided.
