DE1610985B1 - Device for the wet treatment of web-shaped textile goods - Google Patents

Description

and also when the treatment liquid is one having a low viscosity and a low surface tension is. The invention is also advantageous if a textile material with relatively slippery surfaces is used (such as z. B. one made from synthetic fibers or from mixtures thereof with other components consists); Examples of such textiles are those made entirely or in part of polyamide or Polyester fibers are made. Suitable solvents for use in the invention Device are z. B. trichlorethylene, perchlorethylene, trichlorotriflorethane (especially 1,1,2-trichloro-1,2,2-trifluoroethane) and mixtures thereof.

An embodiment of the invention is shown in the drawings.

1 and 2 show vertical sections in the transverse direction and longitudinal direction of a device;

F i g. 3 is a horizontal section of a heating element for the systems shown in FIGS. 1 and 2 shown device.

As can be seen from FIGS. 1 and 2, there are in a container 1 designed as guide rollers Guides 2, over which the web-shaped textile material 3 is guided in the open width. The container 1 is filled with the solvent up to liquid level 5. At the bottom of the container 1 there is a flanged connector 6, which is provided with a cover plate 7, on which as a heating element 8 a steam coil is attached, which has steam inlet and steam outlet pipes 9. The heating element 8 is surrounded by a sleeve as a protective shield 10 in order to limit the transfer of heat.

According to Fig. 3, the heating element 8 consists of a U-shaped bent metal tube, which is through the Cover plate 7 is guided through in two places. The connections 13 and 14 are by welding sealed. Around the heating element 8 in the vicinity of the cover plate 7 sleeves are made as a protective shield 10 tubular metal attached by welds 16 and 17 to the plate 7 and the heating element 8 are connected. Openings 18 are provided in the cover plate 7 to the interior between the heating element 8 and the sleeve to connect to the outside atmosphere for the purpose of air circulation. Threads 11 and 12 are provided for the connection of steam inlet and steam outlet lines.

A conventional heating element can also be used near the edge zone of the textile material (3), which is arranged to reduce the heat transfer from the heating side of the tank, so that the lower element (8) for the treatment liquid with half of the guides in the tank protrudes.
Protective shield (10) is surrounded. If this side-mounted version 5. The device according to claim 1, wherein the form is used, then the heating element should indicates that the edge zones are each 10% 35 so arranged that it is completely related include the width of the textile material (3). on the textile goods guides in the desired position comes to rest (i.e., in a direction transverse to the axis of the guides); or it should be with one Equipped with a protective shield or a protective cover 40 to allow heat transfer into the liquid in the zone near the edge or the edges never to reduce textile goods.

A disadvantage that often occurs at a 60 so the best work area for the size of the Such a treatment occurs, is that the boiling zone is approximately 70 to 90% of the textile width the treated web-shaped textile material folds or makes up.
