Embodiment Construction

[0044] The embodiment of the apparatus shown generally at 11 in the single figure has a conventional dyeing device 10 provided with a container 12 for holding a skein 13 of fabric to be dyed. During the dyeing and rinsing process, the fabric skein 13 is conveyed continuously through the container 12 , wherein in the embodiment shown a driven capstan 14 is used for conveying the fabric skein 13 .

[0045] A dye liquor circulation system 16 is assigned to the bottom region 15 of the container 12, wherein via the dye liquor circulation system 16 the corresponding treatment liquor is discharged from the container 12 by means of a dye liquor circulation pump 17 and a heat exchanger and is discharged in the dye liquor circulation system 16. The liquid is re-introduced in the container 12 after heating. The fabric skeins 13 are conveyed during the treatment by means of the capstan 14 at a predetermined speed in the direction of the arrow 19a, wherein the conveying speed usually varie...

Abstract

The method involves bringing a textile substrate (13) in contact with a dye liquor containing a reactive dyeing material. A colored textile substrate is rinsed after expiration/cycle of a preset dyeing time, and the dyeing material is not fixed through the textile substrate and is present in the dye liquor, is degraded by chemical and/or physical treatment. The dye liquor is formed as colorless, and the textile substrate is rinsed with a decolorized liquor. An oxidative treatment is performed as a chemical treatment, and a treatment with ozone is performed as an oxidative treatment. An independent claim is also included for a device for coloring a textile substrate for performing a method for dyeing a textile substrate, comprising a boiler.

Description

technical field [0001] The invention relates to a method for dyeing textile fabrics with the features of the preamble of claim 1 and an apparatus for carrying out the method with the features of the preamble of claim 13 . Background technique [0002] For dyeing textile substrates, and in particular for dyeing such textile substrates (Substrat), wherein reactive dyes are used as dyestuffs, it is known to bring the textile substrate into contact with a dye liquor containing said dyestuffs, wherein in The colored textile base fabric is rinsed after a predetermined dyeing time. [0003] In this regard, a distinction is made between a pad-stack dyeing method, a pad-steam dyeing method and an exhaust dyeing method according to the respective selected method and the correspondingly provided equipment, but what all methods have in common is that at the end of the actual dyeing process Flushing is sometimes required in order to remove unfixed dyestuff from the textile base fabric c...
