Dyeing or washing installation for narrow textile fabrics and method for removing an excess amount of dye or washing agent

Abstract

The invention relates to a dyeing or washing installation ( 1 ) for narrow textile fabric ( 2 ), the narrow fabric ( 2 ) being passed through a dyeing or washing liquor, followed by removal of the excess amount. To develop further a dyeing or washing installation ( 1 ) of the type in question advantageously with regard to the application of dye and removal of excess amounts, it is proposed that the narrow fabric ( 2 ) is guided along a width-adapted suction nozzle ( 6 ), disposed downstream of the dyeing or washing liquor.

         2 . Dyeing or washing installation according to  claim 1  or in particular according thereto, characterized in that the removal of the excess amount takes place between two passes of the narrow fabric ( 2 ) through the dyeing or washing liquor.  
     
     
         3 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal is carried out at right angles to the direction of movement (r) of the narrow fabric ( 2 ).  
     
     
         4 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the narrow fabric ( 2 ) consists of inelastic material.  
     
     
         5 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the narrow fabric ( 2 ) consists of elastic material.  
     
     
         6 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the narrow fabric ( 2 ) is guided along the suction nozzle ( 6 ) by means of a screen belt ( 14 ).  
     
     
         7 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal takes place in the upward and/or downward direction.  
     
     
         8 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal takes place horizontally and/or vertically.  
     
     
         9 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal takes place at an inclination with respect to the narrow fabric ( 2 ).  
     
     
         10 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that squeezing takes place upstream of suction removal.  
     
     
         11 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that suction removal is carried out from a plurality of narrow fabrics ( 2 ) parallel to one another.  
     
     
         12 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the liquid removed by suction is passed through a water separator ( 10 ) and fed back into the dyeing or washing liquor.  
     
     
         13 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal takes place through a plurality of layers of the narrow fabric ( 2 ).  
     
     
         14 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal from the narrow fabric ( 2 ) is carried out while it runs through spirally.  
     
     
         15 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the narrow fabric ( 2 ) is guided spirally while stretched out on two deflecting rollers ( 20 ,  21 ) which are spaced apart from each other.  
     
     
         16 . Dyeing or washing installation according to one or more of the preceding claims or in particular according thereto, characterized in that the suction removal is simultaneously applied to fabric strands produced by the spiral guidance.  
     
     
         17 . Method of removing an excess amount of colorant or washing agent from a narrow textile fabric ( 2 ) which is passed through a dyeing or washing liquor in a dyeing or washing installation ( 1 ), characterized in that the narrow fabric ( 2 ) is guided along a width-adapted suction nozzle ( 6 ), disposed downstream of the dyeing or washing liquor.  
     
     
         18 . Method according to  claim 17  or in particular according thereto, characterized in that the narrow fabric ( 2 ) is passed a number of times in succession through the dyeing or washing liquor and subjected to suction removal by means of the suction nozzle ( 6 ) to remove the excess amount.
