Example

[0018] A device for coloring textiles in accordance with the present invention has a plurality of wetting stages 1. An oxidation line 2 and a washing device 3 follows each wetting stage 1. Furthermore, the device in accordance with the present invention has not shown means for supplying threads 4, in which the threads are wound for example in a bobbin by spools and supplied to coloring, and means for drying of the colored threads 4.

[0019] Each wetting stage 1 includes means for expelling oxygen 5 from the threads 4, a coloring substance trough 6, and a second squeezing mechanism 7.

[0020] The means for expelling 5 contain a trough 8 with at least one first deviating roll 9, and a first squeezing mechanism 10 arranged at an outlet of the threads 4 from the trough 8. An overflow conduit 11 is attached to the trough 8 and is connected with a drain.

[0021] At a short distance in the running direction of the threads 4 behind the first squeezing mechanism 10, the coloring trough 6 is pro...

Abstract

Coloring of continuous textiles includes pad dying the textiles many times in at least one trough; subsequently green painting the textiles in an oxidation line; then washing and drying the textiles; and expelling oxygen from the textiles immediately before each pad dying, wherein a reintroduction of oxygen in the textiles is prevented before each green painting.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a method for continuous coloring textiles, as well as to the device for performing the method. [0002] Methods and devices of this type are known in the art, for example for indigo coloring of textiles, in which a coloring substance which is not soluble in water is converted by means of alkali or reduction agent into a water-soluble form which has affinity to threads. In this manner the coloring substance can color the threads of the textiles, which is also called pad dying. After a subsequent oxidation which is also known as green painting, the coloring substance obtains indigo blue color. Also, other copper coloring substances such as indanthrene and sulphur coloring substances can be used. The textiles in this application include textile webs or threads. [0003] German patent document DE 43 14 402 A1 discloses a method of indigo coloring of threads, in which the threads are pad dyed with a coloring substances many ...
