Abstract: Apparatus 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 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.

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.

Abstract: Apparatus for the continuous liquid treatment of a running web of a textile material and the like comprises a set of horizontally disposed treatment tanks, means for introducing the web into and through the tanks, means for introducing and distributing treating liquid over the width of the web, and for removing both web and used liquid, and control means for maintaining the depth of treating liquid at a level whereby there is associated with each unit length of web a predetermined quantity of treating liquid during its passage through the apparatus, with means for moving web and liquid through the apparatus at substantially the same speed and in the same direction whereby substantially complete extraction of the treating agent from the liquid is obtained.

Abstract: The dyeing and finishing of textured textile webs made of synthetic fibers is carried out by immersing the web in a hot dye solution, moving the web and solution in the same direction and at the same speed whereby a constant amount of dye liquid is applied to each unit length of web, the web floating in the liquid in tension-free state, the weight ratio of liquid to web being in the range 10:1 to 50:1, and then subjecting the web to a finishing treatment.
