Base fabric for papermaking felt and papermaking felt made by jointing same

Abstract

A base fabric for papermaking felt has a wet-paper-side layer on which a wet-paper-side surface is formed; a roll-side layer on which a roll-side surface is formed; at both ends, seam loop parts connecting the wet-paper-side layer and the roll-side layer and through which core wires are passed in the CD direction, the wet-paper-side layer and the roll-side layer made of MD yarns material in the running direction of the felt and CD yarns material in the transverse direction of the felt, the seam loop parts are formed of MD yarns material; and stuffer yarns passed through near the outer side of one seam loop part and on the inner side of the other seam loop part or near the outer side of one seam loop part and on the inner and outer sides of the other seam loop part. The stuffer yarns are hydrophilic yarns.

1 . A base fabric for papermaking felt having a wet-paper-side layer on which a wet-paper-side surface is formed, a roll-side layer on which a roll-side surface is formed, and, at both ends, seam loop parts which connect the wet-paper-side layer and the roll-side layer and through which core wires are passed in the CD direction,
 wherein the wet-paper-side layer and the roll-side layer are made of MD yarns material in the running direction of the felt (MD direction) and CD yarns material in the transverse direction of the felt (CD direction), wherein the seam loop parts are formed of MD yarns material,   wherein the base fabric for papermaking felt further includes one or more stuffer yarns passed through near the outer side of one seam loop part and on the inner side of other seam loop part or near the outer side of one seam loop part and on the inner and outer sides of the other seam loop part, and   wherein the stuffer yarns are hydrophilic yarns.   
     
     
         2 . The base fabric for papermaking felt according to  claim 1 , wherein the hydrophilic yarns are fiber having a moisture content of 6% or more at a relative humidity of 65% and 20° C. (standard state). 
     
     
         3 . The base fabric for papermaking felt according to  claim 1 or 2 , wherein the hydrophilic yarns are rayon or hydrophilically treated nylon. 
     
     
         4 . A papermaking felt, which is made by jointing the base fabric for papermaking felt according to any one of  claims 1 to 3 .
