摘要:
A device for removing moisture from a continuously advancing textile web by suction. A suction slit which reaches crosswise across the textile web is provided, which is delimited on one side by a slide surface, on the other side by a roll. On the side facing the roll, the slide crosspiece has a concave recess, into which the roll partly fits. At its edge, facing the roll, the slide crosspiece forms a tongue-like projection, which extends over the top of the roll, almost to the vertex of the roll.

A method and a device are provided for the treatment of an endless web of fabric with a washing liquid and employing a vacuum. The treatment medium is withdrawn from the treatment zone and the withdrawn treatment medium is separated in a cyclone into a gas and a liquid. The liquid is pumped back into the treatment zone. The gas is heated additionally in a vacuum generator and is then returned into the treatment zone.

A method of reducing the liquid content of air-permeable material in tubular form, especially for reducing the moisture content of tubular fabric, involves moving the tube of material longitudinally through a device for applying suction to the outer surface of the tube, either in a single area which extends all round the tube or in a plurality of areas which together extend substantially all round the tube.Means for carrying the method into effect may comprise one or more hollow members defining a frame to surround the tube of material from which liquid is to be removed. Each hollow member has apertures in its inwardly-facing wall, each of which apertures communicates with the hollow interior of its hollow member, and means is provided for creating a sub-atmospheric pressure in each hollow member. Preferably, the apertures are in the form of elongate slots having a length considerably greater than their width, and the axis of each slot is inclined at an angle of from 5 to 10 degrees to the direction of advance of the tubular fabric.The liquid extraction means may be combined with hot air drying apparatus disposed downstream of the suction applying means and/or with squeeze rollers disposed upstream of the suction applying means.

An improved process for dyeing carpet by intermittently moving the carpet along a path having horizontal and vertical portions. The horizontal portion of the path is immersed in a print form having compartments separated by thin walls and filled with liquid dyes of varying colors, to impart a desired pattern to the fabric. After the horizontal portion of the fabric is withdrawn from the print form, the fabric is moved along its path so that the immersed portion is moved along the vertical portion of the path. A vacuum slot along the vertical portion of the path adjacent the horizontal portion is activated only while the carpet is in motion, and serves to draw the dye toward the backing of the carpet while removing excess dye therefrom. Thereafter the carpet is steamed to set the dyes.

An apparatus for finishing, especially bleaching and/or desizing knitted fabrics and hosiery goods, such as for example cellulose fibers, wherein the knitted fabrics and hosiery goods are impregnated with the treatment liquor, steam, washed and/or rinsed and dried. The knitted fabrics and hosiery goods are continuously transported and guided in open width and without any substantial tension during the individual treatment stages.

The invention relates to a dyeing or washing installation (1) for narrow textile fabric (2), the narrow fabric (2) being passed through a dyeing or washing liquor, followed by removal of the excess amount. To develop further a dyeing or washing installation (1) of the type in question advantageously with regard to the application of dye and removal of excess amounts, it is proposed that the narrow fabric (2) is guided along a width-adapted suction nozzle (6), disposed downstream of the dyeing or washing liquor.
摘要:
Excess liquid is removed from a fast-moving thread, in that the latter is deflected, so that the liquid is hurled off, the hurled off liquid is removed from the thread, in that the thread is passed through a closed chamber, where a vacuum is produced in order to facilitate liquid evaporation and in that the thread is led through a narrow gap, so that the layer directly surrounding the thread and travelling therewith is peeled off. The combination of these drying effects constitutes one process stage. Advantageously, this process stage is performed several times in direct succession, so that in the case of a thread-protecting, small deflection angle a good thread drying can be achieved. The process is performed by an apparatus comprising several chambers (K.1-3) connected in series in the thread movement direction, the thread being deflected at the inlet and/or outlet with respect to each chamber by a deflection element (U.1-4) and passes through a narrow gap (S.1-). The chamber walls (20.1-4), which carry the thread passage, are inclined away from the thread in the gravity direction. The hurled off liquid, under the influence of gravity flows through corresponding passages, which interconnect the chambers and passes into the final chamber in the thread movement direction and is sucked off from the latter.
