Abstract

The present invention refers to a method for the treatment of threads, wherein after spinning, a preparation liquid having a viscosity of 15 to 70 mm 2 /s at 25° C. and a water content of 0 to 6% by weight is applied to the threads.

Claims

exact text as granted — not AI-modified
1 . Method for the treatment of threads, wherein after spinning a preparation liquid having a viscosity of 15 to 70 mm 2 /s at 25° C. and a water content of 0 to 6% by weight is applied to the threads. 
     
     
         2 . Method according to  claim 1 , wherein the preparation liquid has a viscosity of 20 to 50 mm 2 /s at 25° C. 
     
     
         3 . Method according to  claim 2 , wherein the preparation liquid has a viscosity of 30 to 45 mm 2 /s at 25° C. 
     
     
         4 . Method according to  claim 1 , wherein the preparation liquid has a water content of 0.5 to 4% by weight. 
     
     
         5 . Method according to  claim 4 , wherein the preparation liquid has a water content of 0.8 to 3% by weight. 
     
     
         6 . Method according to  claim 1 , in which the preparation liquid is applied before drawing the threads. 
     
     
         7 . Method according to  claim 1 , where the preparation liquid is applied after drawing the threads. 
     
     
         8 . Use of a preparation liquid having a viscosity of 15 to 70 mm 2 /s at 25° C. and a water content of 0 to 6% by weight for the treatment of threads.
