Papermachine fabric

Abstract

The invention relates to a papermachine fabric having a batt structure extending over the entire width of the fabric, the batt structure comprising at least one ultrathin elongated fiber batt which extends over a part width of the fabric and has a thickness of 0.3 mm or less.

1 . A papermachine fabric comprising: 
 a batt structure,    wherein the batt structure comprises at least one ultrathin elongated batt section that extends over part of a width of the fabric, the ultrathin batt structure having a thickness of greater than 0 mm and less than approximately 0.3 mm.    
   
   
       2 . The papermachine fabric of  claim 1 , wherein the thickness of the ultrathin batt section is greater than 0 mm and less that at least one of 0.25 mm, 0.15 mm and 0.1 mm.  
   
   
       3 . The papermachine fabric of  claim 1 , wherein the ultrathin batt section comprises fibers with a titer in the range from approximately 1 to approximately 150 dtex.  
   
   
       4 . The papermachine fabric of  claim 1 , wherein a plurality of ultrathin batt sections are adjoined in a width extent.  
   
   
       5 . The papermachine fabric of  claim 1 , wherein a plurality of ultrathin batt sections are not adjoined in their width extent when arranged beside one another in one plane.  
   
   
       6 . The papermachine fabric of  claim 1 , further comprising a second ultrathin batt section, wherein the at least one ultrathin fiber batt section differs from the second ultrathin batt section by at least one of permeability, liquid storage volume, compressibility and density.  
   
   
       7 . The papermachine fabric of  claim 6 , wherein the at least one ultrathin batt section has the same thickness as the second ultrathin batt section.  
   
   
       8 . The papermachine fabric of  claim 6 , wherein the at least one ultrathin batt section has a different thickness than the second ultrathin batt section.  
   
   
       9 . The papermachine fabric of  claim 1 , wherein a first ultrathin batt section comprises fibers with a different titer than a second ultrathin batt section.  
   
   
       10 . The papermachine fabric of  claim 1 , wherein the batt structure comprises a plurality of ultrathin fiber batts which are arranged flatly on one another.  
   
   
       11 . The papermachine fabric of  claim 10 , wherein the ultrathin fiber batts are joined flatly to one another.  
   
   
       12 . The papermachine fabric of  claim 10 , wherein the ultrathin fiber batts are joined to one another by at least one of adhesive bonding, fusing and cross-linking.  
   
   
       13 . The papermachine fabric of  claim 1 , wherein the fabric comprises a carrier structure which is joined to at least one of the ultrathin fiber batts.  
   
   
       14 . The papermachine fabric of  claim 13 , wherein a first part of the carrier structure is arranged between a first ultrathin fiber batt and a second ultrathin fiber batt.  
   
   
       15 . The papermachine fabric of  claim 14 , wherein the carrier structure is joined flatly on both sides to the first and second ultrathin fiber batts.  
   
   
       16 . The papermachine fabric of  claim 13 , wherein the carrier structure comprises an ultrathin carrier layer with a thickness of 0.3 mm or less.  
   
   
       17 . The papermachine fabric of  claim 16 , wherein the ultrathin carrier layer comprises at least one of a permeable film, a semipermeable film, an impermeable film, a two-dimensional textile structure such as a woven fabric or a fine woven fabric, a film structure, and a warp knit.  
   
   
       18 . The papermachine fabric of  claim 10 , wherein the batt sections of different ultrathin fiber batts extend parallel to one another.  
   
   
       19 . The papermachine fabric of  claim 10 , wherein the batt sections of different ultrathin fiber batts extend perpendicular in relation to one another.  
   
   
       20 . The papermachine fabric of  claim 1 , wherein the papermachine fabric is one of a forming fabric, a press felt, a dryer fabric, and a transfer belt.
