Method of and device for coloring textiles

Abstract

Coloring of continuous textiles includes pad dying the textiles many times in at least one trough; subsequently oxidizing 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.

1 . A method of coloring continuous textiles, comprising pad dying the textiles many times in at least one trough; subsequently oxidizing 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 oxidation.  
     
     
         2 . A method as defined in  claim 1 , wherein the expelling of the oxygen is performed by immersing in a liquid and subsequent squeezing.  
     
     
         3 . A method as defined in  claim 2;  and further comprising using washing water as the liquid.  
     
     
         4 . A method as defined in  claim 1;  and further comprising maintaining an oxygen-free atmosphere between each expelling of oxygen and the subsequent oxidation.  
     
     
         5 . A method as defined in  claim 4;  and further comprising using a nitrogen atmosphere as the oxygen-free atmosphere.  
     
     
         6 . A device for coloring continuous textiles, comprising a plurality of coloring troughs each connected with a supply of a coloring substance; a second squeezing mechanism connected after each of said coloring troughs; a plurality of oxidation lines each arranged behind the second squeezing mechanism; a washing trough; a dryer; means for expelling oxygen from the textiles arranged immediately before each of said coloring troughs; further means which prevent a contact of the textiles with oxygen between each means for expelling and the second squeezing mechanism.  
     
     
         7 . A device as defined in  claim 6 , wherein said means for expelling include a trough and a first squeezing mechanism.  
     
     
         8 . A device as defined in  claim 7 , wherein each said trough is hydraulically connected with said washing trough.  
     
     
         9 . A device as defined in  claim 7 , wherein said second squeezing mechanism have a same squeezing pressure.  
     
     
         10 . A device as defined in  claim 9 , wherein said first squeezing mechanism is coupled with said second squeezing mechanism.  
     
     
         11 . A device as defined in  claim 6 , wherein said further means for preventing a contact of the textiles with oxygen include a hood.  
     
     
         12 . A device as defined in  claim 11 , wherein said hood is connectable with a nitrogen source.
