Device for the continuous treatment of thick, voluminous textiles

The invention relates to an apparatus for continuous Treating, in particular dyeing and / or printing, thick, voluminous goods of great width, preferably tufted carpets, Plush and needle felts, e.g. made of wool, polyamide and polyacrylonitrile fibers, whereby the textiles continuously have several individual units, namely a padder and / or a cover device, a steamer, a washing device and a dryer go through according to patent ... (Application Az.V31 756 VIIa / 8a).

In the parent application a method and an apparatus for continuous dyeing or printing of thick, voluminous textiles such as carpets. A special feature of this The invention is that the device is used both for dyeing tufted carpets and for dyeing and optionally consolidating Needle felt carpets are suitable.

Thorough experiments with tufted carpets and needle felt carpets have shown that the impregnation or pressure device is of particular importance in this system. It will be as low as possible Striving to take up the fleet in order to achieve the highest possible profitability to reach. With needle felt carpets, a good squeezing effect can be achieved with the dye padding if the rollers are relatively hard. With tufted carpets, however, there is Again there is the danger that the pile will be printed by the hard walls and the printed pile layer is fixed in the subsequent steamer. Favorable results with tufted carpets are achieved when the foulard relatively large, soft rollers with a hardness of the above. 20 Shore or, the Preöwalzen with such a rubber

are covered. The press rolls for needle felt should as possible Have a hardness of 75 - 80 Shore in order to obtain a favorable "squeezing effect". These two requirements contradict themselves. One helps sicli with tufted carpets by that These carpets are not squeezed off as strongly, i.e. with a higher moisture level in the steamer if a padder is used relatively hard rollers are used. However, this has considerable disadvantages: On the one hand, it results in higher chemical costs and for others require a higher steam consumption in the damper. Becomes a If a padder with less hard rollers is used, then the liquor pick-up with needle felt is correspondingly higher and thus again the energy and chemical costs.

The invention is now based on the object of a! Continue— to build a dyeing plant in which both tufted goods and goods with ~~ a relatively high and soft pile can be dyed flawlessly with great economic efficiency as well as needle felt carpets.

According to the invention, it was recognized that a compromise in the drinking tippers Printing device between tufted and needle felt goods always leads to a reduction in the quality of both types of goods and to a poorer quality Economics leads and therefore such a compromise must be avoided.

According to the invention, it is therefore proposed in a device of the type described at the outset to arrange an impregnation or pressure device for tufted carpets and for needle felts in front of the damper and to assign transport elements to the two impregnation or pressure devices, which require driving around, ie driving over or under, one at a time allow these drinking facilities. This makes it possible to use a padder or a printing device, one of which gives the most favorable values for tufted carpets and is specially designed for this type of goods, and the other is designed for needle-felted goods. Depending on which material is being used, one or the other of the impregnation or pressure

direction of application. Steamers, washing baths and dryers remain completely the same for both materials. The invention makes it possible to achieve a quality improvement in both tufted and needle felted goods. Ils is .möglich, two well-known per se foulard or Tränkeinr i chlungen to use, as they are offered for needlefelt and tufted carpets and used.

However, it is also possible to provide only one impregnation or pressure device and only two of this impregnation or pressure device Assigning presses, one of which is specially designed for tufted carpets and the other is designed for needle felts. Depending on the type of material, one or the other press is used. The goods can either pass through both presses, with only one press being put under pressure, or they can be routed around the press unit that is not in use.

An exemplary embodiment of the invention is shown schematically in the drawing shown in longitudinal section.

The device shown consists of a padder 1 for impregnating needle felt goods. This padder has relatively small, hard press rollers 2 with a hardness of 75-80 Shore and a diameter of about 20-25 cm. Another padder 3 for tufted carpets and plush is assigned to the padder 1 for needle felt, which has relatively large, soft press rollers h . Rollers 5 are provided on both pads, which make it possible to guide the material web to be treated over the padder without passing through the padder. The damper 6 shown has a screen drum 7 under suction and driven Y / cylinders 8, over which the material is guided in running loops. A heated cylinder 9 with a suction box 10 is provided at the inlet and a water lock 11 is provided at the outlet. These parts ensure an air-free atmosphere in the damper. Thereafter, suction drum baths 12 with associated presses 13 are arranged. The downstream sieve drum dryer lh is only used for drying needle felted civars.

A roller conveyor 15 allows tufted carpets to be bypassed of the dryer. For strengthening needle felt or for applying the Another foulard 16 is used for binder solution. Dried and condensation is applied to a sieve drum dryer 17 with a Big drum IS. The direction of rotation of the large drum 18 can be changed This makes it possible to use the top of the carpet on needle felt carpets against the sieve drum and thus to achieve a depletion of binders on the upper side and with tufted carpets to lay the carpet against the sieve drum so that the loops cannot be printed in the hot drying atmosphere. The situation is analogous for printing. Also here has one suitable pressing of great importance.
