Papermachine fabric

Abstract

The invention relates to a papermachine fabric, in particular a press felt, having a carrier layer on which, at least in some sections, fibers with exposed fiber ends are arranged, the fibers forming a contact surface with which a paper web can be brought into contact, and wherein the contact surface is substantially formed by the exposed fiber ends.

1 . A papermachine fabric, comprising a carrier layer on which fibers with exposed fiber ends are arranged, the fibers forming a contact surface with which a paper web can be brought into contact, wherein the contact surface is substantially formed by the exposed fiber ends.  
   
   
       2 . The papermachine fabric as claimed in  claim 1 , wherein the carrier layer has a surface in relation to which the fibers extend at an angle (α) between 45 and 90°.  
   
   
       3 . The papermachine fabric as claimed in  claim 1 , wherein the fibers extend substantially perpendicular to the surface of the carrier layer.  
   
   
       4 . The papermachine fabric as claimed in  claim 1 , wherein a binder layer is arranged on the surface of the carrier layer in order to hold the fibers.  
   
   
       5 . The papermachine fabric as claimed in  claim 4 , wherein the fibers are embedded in the carrier layer by means of needling and penetrate the binder layer.  
   
   
       6 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at leat one of the surface of the carrier layer and the binder layer by less than 1 mm.  
   
   
       7 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at least one of the surface of the carrier layer and the binder layer by less than ten times the fiber diameter.  
   
   
       8 . The papermachine fabric as claimed in  claim 4 , wherein the fibers having a fineness index of 3.3 dtex, 250,000 to 325,000 fibers per cm 2  are arranged in at least one of the carrier layer and the binder layer.  
   
   
       9 . The papermachine fabric as claimed in  claim 4 , wherein the binder layer is softer than the fiber material and formed of a thermoplastic elastomer.  
   
   
       10 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at leat one of the surface of the carrier layer and the binder layer by less than 0.5 mm.  
   
   
       11 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at leat one of the surface of the carrier layer and the binder layer by less than 0.3 mm and more than 15 μm.  
   
   
       12 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at leat one of the surface of the carrier layer and the binder layer by less than 1 mm and more than 15 μm.  
   
   
       13 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at least one of the surface of the carrier layer and the binder layer by less than five times the fiber diameter.  
   
   
       14 . The papermachine fabric as claimed in  claim 4 , wherein the ends of the fibers project beyond at least one of the surface of the carrier layer and the binder layer by less than three times the fiber diameter.  
   
   
       15 . The papermachine fabric as claimed in  claim 4 , wherein the fibers having a fineness index of 6.7 dtex, 125,000 to 200,000 fibers per cm 2  are arranged in at least one of the carrier layer and the binder layer.
