Process and high-pressure steamer for dyeing thick textiles

The invention relates to a method for dyeing thick Textile goods, especially blankets and carpets, and a high-pressure damper for carrying out this process.

For example, when making blankets, a Raising treatment carried out so that a surface with a hair blanket can be made from long erect Hair consists of textile materials used for the production of carpets, the upright surface areas have to form pile, woolen hair or the like. Large amounts of water are used to dye such textiles and a relatively large amount of work is required. In known processes for dyeing such textiles machines are used in which · textile goods with a predetermined Length repeatedly dipped in a staining liquid must become. A relatively long time is therefore required for dyeing such textiles. Because of the big one Heat and water requirements are such processes

■ r

nism moderately uneconomical. Furthermore, if a single dyeing device As a Wince dyeing machine is used, different or uneven dyeing of unit lengths of the textile material can result. Furthermore, wrinkles can form occur during inking.

There were already procedures for coloring in older applications proposed by Textilgut, which has a thickness that is suitable for shirts or other items of clothing and allows impregnation and fixation without significant difficulties. However, thicker textile material can be used in this way mentioned type are not colored because in such a material provided with a hair blanket or the like the staining liquid does not readily enter the material or penetrates between the fibers in a relatively short period of time. That is why it has been difficult so far to achieve a uniform To achieve coloring of thick textiles with a relatively short treatment time.

It is therefore the object of the invention to provide a method and specify a high-pressure damper for performing the method for dyeing thick textile goods with which the Textile goods with the greatest possible avoidance of the disadvantages and difficulties mentioned at the highest possible transport speed can be colored continuously. For example, it should be made possible that textile goods with a Hair blanket, which has a thickness of about 12 mm, with a raised Throughput speed can be colored. According to the invention, this object is achieved by the subject matter of the patent claim 1 or claim 2 solved.

In summary, therefore, the essential features of the invention are in a method for dyeing thick textile materials such as blankets or carpets, in which the textile material is impregnated with a dye liquid and then in subjected to a first coloring process in a tension-free state is, with a steam treatment in a front area

a high pressure damper takes place. After this first dyeing, a second dyeing process takes place, in which the textile material through a flowing dye solution is transported into a container in a rear area of the high pressure damper. The high pressure damper contains a number of guide rollers in the front area, which enable tension-free transport of the textile material. The container through which the coloring liquid flows is arranged in a rear area of the high-pressure damper and stands with a circulation line for the dye solution in Link.

Based on the drawing, the invention is intended, for example are explained in more detail. The single figure shows a sectional view of a high-pressure damper according to the invention.

The high-pressure damper 1 shown has an inlet 2 and an outlet 3. A sealing device 4 is provided at the inlet 2 and a sealing device 5 is provided at the outlet. The sealing devices enable sealing during the transport of textile goods 11 through the high-pressure damper. The sealing device 4 contains two rubber rollers 4,, which are pressed against each other, a sealing container A ~ which is filled with liquid and is arranged closer to the inlet 2 than the rubber rollers, and nip rollers 4,. The sealing device 5 at the outlet contains two rubber rollers 5 pressed against one another, and a cooling container 5 ″, which is arranged closer to the outlet than the rubber rollers 5.

A group of rollers 6 is arranged in a row in the area of the front half of the high pressure damper. Each of the rollers 6 is connected to a drive mechanism in order to enable the transport of the textile material in a tension-free state. Each of the rollers 6 is driven at a predetermined speed. Seen in the direction of transport, a container 7 is arranged behind the rollers 6. Coloring liquid 8 flows through the container 7. This coloring liquid is the same as that with which the container 4 _{2 is} filled. The coloring liquid 8 is at the upper end of the inclined container

7 and flows out at the lower end. On the container 7 is a circulation line 9 at the opposite ends of the Container 7 connected. In the circulation line 9 is a pump 10 provided, through which the coloring liquid 8 with a constant Flow rate is circulated through the container 7.

The textile material 11 has a thickness of, for example 10 mm and has a surface treated in such a way that a hair blanket or the like is provided. in transport direction behind the container 7 squeeze rollers 12 for squeezing out dye liquid are arranged.

When starting up, the high-pressure damper 11 is first heated to a temperature of 120 to 150.degree. Dyeing liquid is fed to the container 4 via a feed line 4 in order to maintain a constant liquid level in this container. The cooling container 5 ″ in the sealing device 5 at the outlet of the high-pressure damper is constantly supplied with water which, for example, has the temperature of the water pipe.

Thereafter, textile material 11 is transported in through the sealing device 4 and in the process in the dye liquid in the container 4 “immersed. -The material impregnated with coloring liquid is expressed by the nip rollers 4_ in order to remove air contained in the textile material 11 and to ensure better penetration to allow the dye liquid in the interior of the textile. After squeezing out an excess amount the dye liquid through the squeegee rollers is the textile material in the interior of the high pressure damper and then over the driven rollers 6 transported in a tension-free state. During this transport of the textile material, the dye in the dye liquid is applied to the textile material by steam treatment fixed. The steam treatment under high pressure and at high temperature causes felting and heat treatment effects for the textile material 11 at the same time. A primary dye fixation of the Textile material 11 therefore takes place while the textile material is transported over the guide rollers 6 before it reaches the container 7, through which the coloring liquid flows. In the container 7

the textile material 11 is caused by the flow of the dyeing liquid ■ transported further, in which the textile is immersed. After exiting the container 7 is through the nip rollers 12 Dye liquid squeezed out of the textile material. In this A second dyeing of the textile takes place at Transport through the staining liquid in a tension-free Condition due to the container 7. which can occur in the first coloring process are eliminated in the second coloring process in order to achieve a homogeneous coloring to ensure. The flowing coloring liquid in the The container 7 also prevents creasing in the textile material 11, so that a good texture of the textile material is maintained can. After the dye liquid has been squeezed out by the squeeze rollers 12, the textile material gradually increases to about 50.degree cooled during transport through the cooling container 5_ and then reaches the outside of the high-pressure damper for further treatment perform. According to a modified embodiment of the invention, the first dyeing of the textile material can also take place outside the high-pressure damper.

According to the embodiment described can therefore relatively thick textile material that is used, for example, for Production of blankets or carpets is suitable, homogeneously and dyed with good efficiency in the first dyeing process in a tension-free state under the action of steam takes place in the high pressure damper. During the second coloring process in the high-pressure damper, further transport takes place in a flow of coloring liquid. During the first coloring process furthermore, a felting and a fixing process are effected simultaneously on the textile material. In the second inking process Wrinkles avoided, so that improved quality properties of the dyed textile material can be achieved.
