DE2216758B2 - Device for the continuous patterning of web-shaped textile goods - Google Patents

Description

The invention relates to an apparatus for continuous patterning, e.g. B. dyeing or printing, of textile goods in web form, in which the textile goods before and after the application of the sampling agent each passed through a treatment chamber with a gaseous atmosphere and the applicator is arranged outside the same.

It is known to transfer dye liquids inside a damper onto a continuously advancing web of material to apply. In some cases it is desirable to do this before applying the dye To expose to a steam atmosphere, but nevertheless to work with a dye liquid which has a lower temperature than the vapor space, e.g. B. when the drawing speed is below the temperature of the vapor space has a maximum. Other reasons may also seem desirable let to remove the applicator from the steam atmosphere, such as the fact that the mechanical Parts of the application mechanism suffer damage in the steam atmosphere or the steam atmosphere chemically or physically with the sample agent to be applied, e.g. B. the dye reacts.

From the German Offenlegungsschrift 19 49 801 it is known to carry out printed, web-shaped textile goods to guide a horizontal pre-fixing damper, then the textile material out of the pre-fixing damper and to lead through a commissioned work for another application of paint and then into a hanging loop damper to run in.

In this embodiment, the applicator is located outside of the steam atmosphere of the Vorfixierdämpfers and the hanging loop damper, but the individual damper levels are as separate units connected in series, which is a considerable structural, energy-wise and control-wise Effort means

The invention has the task of with the

Sampling of web-shaped textile goods by a

outside of the gaseous treatment atmosphere

the work involved

to decrease.

To solve this problem, the invention provides that the textile material before and after passing through the

, o Applicator is passed through the same treatment chamber that has an additional outlet and inlet is provided.

Everything takes place in a single, uniform treatment chamber, so that despite the two

, 5 of the following treatments in the treatment atmosphere c no two separate housings with associated installation are required. The commissioned work as, such is, as it is located outside the treatment chamber, not the chemical and by the

exposed to attacks of the treatment atmosphere caused by high temperatures. Nevertheless, the Application immediately after leaving the treatment atmosphere. Arrived immediately after the order the textile goods back into the area of treatment

atmosphere. If the treatment takes place in a steamer, the textile material emerges in a steamed state the damper off, this steaming to fix or fix a previous coloring or originate from a previous pressure or can only be used to heat up and prepare the textile material. The sample agent is applied in the area outside the treatment chamber. A short one Way outside the treatment chamber until the re-entry takes place immediately after the order.

Fencing in the same ensures an immediate attack or re-attack of the treatment atmosphere. if For example, if it is about steaming during dyeing or printing, the dye liquid is located on the textile material during the first part of the run after re-entering the damper housing at the desired temperature deviating from the damper temperature, which has a maximum drawing speed results, and is only then after covering a certain distance in the damper housing heated to the temperature corresponding to the actual fixation. Another benefit of the Invention with several successive Färebzw. Printing operations consists of an application of paint after the previous application of paint has been pre-set on the still warm textile material and that Textile material then immediately enters the damper housing again, so that no renewed heating of the textile is required and considerable energy costs can be saved. Finally an externally arranged commissioned work is of course much lighter, z. B. for the purpose of cleaning, accessible.

In a first embodiment it can be provided that on the top of the treatment chamber a Transversely to the textile extending recess is provided with substantially vertical walls, the contain the additional outlet and inlet, and that the applicator is arranged in the recess.

Another embodiment is characterized

fi5 shows that the textile material from the treatment chamber through the outlet vertically down to the applicator and again after passing through the applicator horizontally through the inlet into the treatment chamber

In the F; G. 1 and 2 of the drawing are two Embodiments of the invention are shown.

1 shows a section of the upper side of a belt conveyor chamber 2, denoted by the dash-dotted line 1, in which a web-shaped textile material 3 runs in the direction of the arrow 4 over support rollers 5. In your area 6, the top of the lighting chamber 2 has a recess 7 which is bounded by vertical walls 8 and 9; is. An additional outlet 10 is provided in the wall 9, while the wall 9 has an additional line 11. The textile material 3 exits the processing chamber 2 at the outlet 10. In the area 6, an outer stretch is laid back and straight back into the treatment chamber 2 at 11. In area 6 it is guided on support rollers 5 '. Above the textile material 3, in the area 6, there is an application unit IZ which consists of a trough 13 extending across the width of the textile material 3, a roller 14 rotating therein and a squeegee 15 which rests against the roller 14 and which tapes against the textile material 3 . The surface of the roller 14 takes liquid with it from the trough Ii as it rotates. The flaw 15 strips the liquid from the surface of the roller 14 and transfers it to the textile material 3.

The order of the liquid, which is a coloring liquid can be, takes place on the just emerged from the outlet 10 Textiigin 3, which after the application

<the inlet II immediately back into the treatment hammer 2 arrives. The distance covered is short,

d. H. only as long as it is for structural reasons Placement of the commissioned work 12 is required.

The course of the textile material 3 in the treatment chamber

By the way, over 2 is arbitrary. It can e.g. B. on that Textile material 3 a dye liquid has already been applied beforehand, which on the in front of the outlet 10 lying running route vorfbcieri is.

In Fig. 2 shows another embodiment, in which the textile material 3 is printed, the textile material 3 first passes through in a horizontal direction Loop the upper part of the treatment chamber 2 '. It then arrives at an outlet 10 'and continues running vertically below and is attached to a commissioned work 12 ', which is listed as in

ü a kind of niche 7 'of the chamber housing housed printing unit is formed. printed- Even after this printing process, the textile material 3 runs horizontally at the F.inlaß 1Γ back into the treatment chamber ¹ "2 '.
