Abstract: An apparatus for dyeing a fabric material comprising a semicircular dye vessel having at opposite ends upwardly directed openings, a first conduit and second conduit connected at one end to the respective openings of the vessel, a dye feed box with a jet nozzle and a deflecting means operatively associated with the jet nozzle. The fabric material is a narrow strip of tape bonded at both ends to form a loop. The deflecting means is rotatable in the first conduit for deflecting the flow of fabric material and dye liquid at an angle of approximately 45.degree. with respect to the vertical axis of the first conduit, the fabric material being oriented to form a succession of loops deposited one upon another and extending substantially radially of the vertical axis.

Abstract: After a dyeing operation has been concluded, the hot dyeing liquor present in the piece dyeing jet is returned via a cooling heat exchanger in the dyeing circulation system back into the makeup storage vessel for the dyeing liquor. Thereafter, the liquor-free dyeing system, which is still under an elevated static pressure, is relieved to atmospheric whereby the dyeing system is cooled down adiabatically together with the dyed textile material present therein to such an extent that a sample can be taken therefrom rapidly and safely.

Abstract: Process and apparatus are provided for the batchwise wet treatment of textile material with an aqueous liquor that contains dyestuff or other textile processing products according to an exhaust technique. Textile material in continuous loop form is recirculated in a jet dyeing machine, and a recirculating gas stream propels the material. A blower recirculates the gas stream while aqueous liquor is metered into the stream by aspirating the liquor at the upstream side of the blower. The action of the blower finely disperses the liquor within the gas stream.

Abstract: The invention relates to a material store for the through transport of a length of textile material. It contains a storage vessel with an upright delivery shaft, an upright extraction shaft and a turn-round section which connects the lower ends of the shafts, and transport arrangements for the delivery and removal of the length of material are provided above the two shafts. In the turn-round section of the storage vessel the length of material is turned round with the aid of a rotating turn-round device and a break roller can be pivoted from the inner face of each of the shafts into the cross-section of the shaft.By these means the length of material is transported through the storage vessel satisfactorily and extremely gently with an extremely high degree of stabilization.

Abstract: The invention relates to a method and apparatus for the treatment of continuously moving tubular fabric (1) in the wet state, in which this tubular fabric is deliberately expanded in an expansion zone (3) by blowing air in and the fabric width (WB) effectively obtained is measured. The actual value obtained for the fabric width is compared with a predetermined theoretical value and in the event that they differ a correction value is formed and the quantity of air blown into the tubular fabric is controlled as a function of this correction value. The tubular fabric (1) is expanded immediately after wet treatment and is then delivered to the expansion zone free of tension and with a sealing material store. In this way a compact apparatus is achieved which functions simply and reliably.

Abstract: In industry there is, for economic reasons, an urgent need to be able to carry out the drying of moist textile material immediately after a completed wet-treatment in the same apparatus in which the preceding treatment operation was carried out.According to the invention the problems arising in the case of textile materials treated in rope form on jet units are solved by evaporatively dewatering the textile material in rope form by means of the gaseous agent which in the case of fabric-advancing jet systems operated by flowing liquor, steam or hot air takes over the transport of the goods immediately after the wet-treatment and which acts on the textile material under a predetermined variable superatmospheric pressure, then cooling the circulating drive gas to condense out the absorbed moisture, and recirculating the air thus dried.

Abstract: The invention relates to a process and device for the wet treatment of textile material in hank form. The material travels in a circulating passage through an intensive treatment drawframe with subsequent folding-down, further conveying, and finally renewed feeding to the intensive treatment drawframe by a hank winding device. Circulating conveying of the treatment bath through the intensive treatment drawframe occurs while the textile material is passed through the horizontally arranged intensive treatment drawframe essentially at the same speed as the treatment bath. Such material is also under the action of the tensile force of a second hank winding device, which works at essentially the same conveying speed as the hank winding device upstream from the intensive treatment drawframe.
