Apparatus for the continuous washing of lengths of textile material

An apparatus for the continuous wet treatment of liquid-permeable textile material includes a sieve drum located within a container that is filled with treatment liquid, with the drum being at least partially immersed within the liquid. A treatment chamber is formed between the sieve drum and one of the container walls and liquid is fed to this treatment chamber from a distributor duct located above the treatment chamber. The distributor duct includes a liquid discharge slot for feeding the liquid to the treatment chamber. A pump is provided for feeding liquid into the distributor duct and the liquid discharge slot is arranged to fed liquid uniformly across the operating width of the sieve drum.

Apparatus for the continuous wet treatment of liquid-permeable textile

A process for the continuous shrinking of textiles includes initially exposing the material to the effect of a hot treatment liquid prior to placing the material on a curved support, and then, to obtain complete shrinkage, allowing the same treatment medium to flow through the material, disposed loosely on the support, and thereafter drying the material and setting the material on a sieve drum under a suction draft. In this process a plurality of twisted yarn threads are shrunk in the wet state together in parallel, side-by-side relationship at temperatures of about 85.degree.-95.degree. C.; the threads are then cooled by cold water and, subsequently, are deposited without tension on a sieve drum subjected to a throughflow of a heated gas to further develop the thus-obtained shrinkage. During this heating step, the threads are initially gradually dried in a cooling temperature range of from 50.degree.-60.degree., compressed, optionally by differences in the speeds of successive sieve drums. Then shrinkage is set, by gas being drawn through the threads, which are further guided in parallel to one another at a temperature of 180.degree.-200.degree.C.

An apparatus for treating a length of textile material which has a pile surface includes at least one sieve drum washing bath for washing the entire width of the textile material to even out or level irregularities across the width of the pile surface, a first steamer unit for treating the washed textile material, a dye applicator unit for applying dye to the steamed and washed textile material and a second steamer unit for treating the dye-containing textile material with steam to fix the dye to the textile material. The sieve drum washing bath includes a sieve drum positioned within a container for the treatment liquid and is provided with a plurality of nozzle openings arranged within the container and spaced closely adjacent to the sieve drum for directing the treatment liquid in the form of a plurality of jets across the width of the textile material being supported on the sieve drum.

Using a continuous open-width washing machine for pile-structured

A process for the continuous washing of printed dye-fixed, web-shaped textile material, e.g. woven or knit fabrics formed of natural and/or synthetic fibers, on a full-width washing machine which involves first moistening the textile material, allowing the textile material to dwell in a folded condition, the dewatering of the textile material and immediately thereafter subjecting the textile material to an intensive throughflow from the outside toward the inside of a washing material on a rotating sieve drum. In this process in order to promote the swelling of the printing paste or the like, the textile material dwells in a cold liquor and then a film detachable from the textile material which covers the textile material is removed mechanically and thereafter the textile material is subjected to the intensive throughflow with a hot liquid on the sieve drum.

An apparatus for the wet treatment of fibrous materials includes a container filled with a treatment liquid, a liquid-permeable support for the material arranged with a supporting surface at least partially underneath a first liquid level within the container, and means for providing a second liquid level extending uniformly along the entire length of the immersed supporting surface and underneath said supporting surface of the support.

Apparatus for the wet treatment of tension-free guided material

A process for the continuous dyeing or printing of lengths of textile material, such as carpet panels having a portion which consists of shrinkable fibers that are set prior to the application of dyes or printing inks includes the step of forcing a hot liquid medium through the length of textile material. An apparatus for effecting this process includes a sieve drum through which the hot liquid medium flows from the inside towards the outside with the material lying on the circumference of the sieve drum.

Process for the continuous dyeing or printing of lengths of material

An apparatus for the drying of lengths of textile material impregnated with a disperse dye or synthetic resin dispersion, which includes a preparatory drying section wherein the length of textile material is conducted in a contact-free manner and is subjected to a first drying operation and a sieve drum means for effecting a final drying treatment. The preparatory drying section includes a transverse tentering frame having a traveling transverse tentering means and is arranged upstream of the sieve drum means. This transverse tentering means is guided through a drying unit for effecting the preparatory drying operation.

Apparatus for the drying of lengths of textile material

An improved process for the continuous dyeing or printing of lengths of textile material, especially tufted carpet panels, having backing materials which are subjected to at least partially a change in length during a dye fixation process of the pile portion of the textile material under saturated steam conditions, the process including the step of setting the fibers making up the backing material prior to applying dye to the pile fibers.

Process and apparatus for the continuous dyeing or printing of endless

A heated roll for effecting heat treatment of materials has an outer cylindrical shell, an inner cylindrical shell spaced from the outer cylindrical shell, a wall defining an annular space between the shells, partitions in the annular space for forming flow channels for the heating medium passing through the inner space, feed means for introducing a heating medium into the annular space and a discharge means for discharging the heating medium from the annular space and from the roll. The discharge means includes a centrally located backflow conduit and defines a single stationary discharge opening arranged in the roll below the roll axis for discharging heating medium selectively from the lower portion of the roll to the centrally located backflow conduit.
