Spinning plate

Abstract

The invention relates to a spinning plate for the production of melt-spun fibers in order to produce geotextiles.

1 . Method for the production of geotextiles, wherein the production of the continuous fibers of different texture takes place in one spinning process, wherein the adjustment of the ratio of fibers of finer and coarser texture is defined and, in the subsequent mechanical and/or hydraulic solidification, a geotextile with defined properties is produced.  
     
     
         2 . Method as claimed in  claim 1 , wherein the finer fibers have a texture of 1-10 dtex.  
     
     
         3 . Method as claimed in  claim 1 , wherein the coarser fibers have a texture of 5-30 dtex.  
     
     
         4 . Method as claimed in  claim 1 , wherein the proportion of finer fibers is 20-95%.  
     
     
         5 . Method as claimed in  claim 1 , wherein two or more fibers of different texture are produced in one spinning process.  
     
     
         6 . Spinneret plate for the production of melt-spun continuous fibers for geotextiles, wherein the spinneret plate has bores of different diameters for producing fibers of different texture in one spinning process.  
     
     
         7 . Spinneret plate as claimed in  claim 6 , wherein the bores have identical or different non-round cross sectional shapes.  
     
     
         8 . Geotextile produced utilizing a method claimed in  claim 1.
