DE3123102C2 - Process and sampling fleet for irregular, multicolored sampling of textile fabrics - Google Patents

Abstract

The invention relates to a method and a sampling fleet for irregular, multicolored sampling of air-permeable flat structures. For the process, the use of a prefabricated, chemically stable sampling liquor is proposed, the inner phase of which consists of an anionic dye paste and the outer phase of a cationic dye liquor. The composition of the sampling fleet is specified in more detail.

Description

The invention relates to a method for irregular, multicolored patterning of textile fabrics, in which a patterning liquor containing several dyes is applied to the fabric, the dyes are sucked into the fabric and fixed by the action of heat. The invention relates to also the sampling fleet.

From DE-OS 29 05 945 a method for patterning material webs is known, with the to Design zones tapering to the edges, d. H. soft transitions between the adjacent zones can be achieved. In this process, the colored subsets of the patterning liquid are through a specially arranged above the application device Dispensing device released into or onto the carrier liquid shortly before the application of the dye liquor. The number the sampling colors is limited by the feeding device.

Furthermore, a similar sampling process is out

ίο the US-PS 18 46 845 known, in which the Bemusf.erungsfarben through contact between the air-permeable material web and that on the surface of the moving carrier liquid applied floating paint film to the web of material; be, afterwards the dyes are sucked into the textile goods and the carrier liquid is sucked off. Even the number of sample colors is limited and depends on the number of devices required, which supply the sample colors to the carrier liquid.

The invention is based on the object to testilen Flat form an irregular, 'multicolored pattern with sharply delimited color areas using conventional equipment and avoiding the disadvantages of the known methods to reach.

To solve this problem, a method of the type mentioned at the outset is proposed, which is characterized in that is that a chemically stable sampling liquor is used, which consists of an inner and a outer phase, the inner phase being a paste of anionic dyes or disperse dyes, an anionic acid-resistant thickener, an acid, a temporary foaming agent, an anionic and optionally one non-ionic auxiliary and water and the outer phase a liquor made of an acid-resistant non-ionic Thickening agent, an acid, a silicone defoamer, a cationic and a nonionic Aids. W.isser and optionally disperse dyes.

In the method according to the invention, a practically unlimited number of sampling colors can be used, since the sampling fiotte can be prefabricated in conventional paint containers, which means that the special devices for adding the dyes to or into the carrier liquid are also omitted.
In order to achieve further pattern marks, the patterning process according to the invention can be combined with a conventional printing and / or dyeing process.

A sampling fleet as claimed can be used to carry out the proposed method 3 is marked.

For the inner phase, metal complex dyes, such as. B. Acid red 315 or Acid green 109, particularly suitable.
Instead of anionic dyes, disperse dyes can also be used.

All customary anionic and acid-resistant agents can be used as thickeners in the inner phase be used.

Formic acid is the acid component of the inner phase brought the best results. Other acids such as B. sulfuric acid, but can also be used.

As a temporary defoamer, for. B. an alcohol

defoamers (mixture of high-quality alcohols) can be used.

The anionic adjuvant, e.g. B. an ether sulfate, and the non-ionic auxiliary, e.g. B. an Aikylpolyglyko-Iäther, serve to fix the dyes on the web and to network the web.

As a thickener of the outer phase, for. B. modified throats in question.

In addition, there is a strong acid for the outer phase, which promotes the fixing and absorption of the dyes, required. For this purpose, z. B. a dicarboxylic acid mixture (Adipic + malonic + tartaric acid).

Finally, as a cationic aid, for. Legs quaternary ammonium compound are used and an alkyl polyglycol ether as a nonionic auxiliary Find use.

The viscosities of the outer and inner phases depend on the available dye liquor application options, the dye liquor preparation station, the pattern effects and 4sr to be sampled accordingly Were.

With the method according to the invention, all fabrics and fiber types that deal with anionic or disperse dyes can be colored.

The method is e.g. B. carried out as follows:

First, the trunk thickening of the inner phase is made, then according to the number of the colors to be used are taken from the Stammveraickung and added to each Partial amount of dissolved dyes, if “Also required Aids and water, given and mixed.

Then the outer phase with <; ii specified Components

The sub-quantities of the inner phase, which have been set with different color nuances, are then added one after the other into the outer phase and stir until the inner phase undergoes the desired crushing Has. The amount of the inner phase that is added to the outer phase depends on the desired Pattern effect

The chemically stable sampling fleet, prefabricated in this way in common facilities, is becoming more common Wise, in particular by pouring, applied to the textile flat structure, the inner phase in the flat structure sucked in and the outer phase sucked off essentially. Then the dyes fixed in the damper on the web. The separated dyes become the inner ones and outer phase of the chemically stable, inventive sampling liquor locally, without running, fixed on the fibers, so that sharply delimited pattern areas are created. After that, the becomes irregular and multi-colored patterned webs washed and dried in a conventional manner.
