Wear side weave pattern of a composite forming fabric

Abstract

A fabric for papermaking including a first layer side, a second layer side and at least one binder warp yarn pair. The first side layer, having a plurality of first weft yarns and a plurality of first warp yarns. The second side layer having a plurality of second weft yarns and a plurality of second warp yarns. The at least one binder warp yarn pair including a first binder warp yarn pair having a first binder warp yarn and a second binder warp yarn, the first side layer and the second side layer being bound by the first binder warp yarn pair. The first binder warp yarn and the second binder warp yarn exchanging the layer to which they are woven at exchange points. A knuckle is formed with the first binder warp yarn and an adjacent first warp yarn, a subsequent adjacent knuckle only being formed with the first binder warp yarn and an opposite adjacent first warp yarn.

1 . A fabric for papermaking, comprising:
 a first side layer, having a plurality of first weft yarns and a plurality of first warp yarns;   a second side layer having a plurality of second weft yarns and a plurality of second warp yarns; and   at least one binder warp yarn pair including a first binder warp yarn pair having a first binder warp yarn and a second binder warp yarn, the first side layer and the second side layer being bound by the first binder warp yarn pair, the first binder warp yarn and the second binder warp yarn exchanging the layer to which they are woven at exchange points, a knuckle being formed with the first binder warp yarn and an adjacent first warp yarn, a subsequent adjacent knuckle only being formed with the first binder warp yarn and an opposite adjacent first warp yarn.   
   
   
       2 . The fabric for papermaking of  claim 1 , wherein no more than four knuckles are formed between exchange points on the first layer along the binder warp yarn pair. 
   
   
       3 . The fabric for papermaking of  claim 1 , wherein no more than two knuckles are formed between exchange points on the first layer along the binder warp yarn pair. 
   
   
       4 . The fabric for papermaking of  claim 1 , wherein the knuckle is a first knuckle, the subsequent adjacent knuckle is a second knuckle, the second knuckle being the last knuckle prior to an exchange point, after the exchange point the second binder yarn forms a third knuckle with the adjacent first warp yarn. 
   
   
       5 . The fabric for papermaking of  claim 4 , wherein the second binder yarn forms a fourth knuckle with the opposite adjacent warp yarn. 
   
   
       6 . The fabric for papermaking of  claim 5 , wherein on the first layer side the at least one binder warp pair only has alternating knuckles in a repeating pattern. 
   
   
       7 . The fabric for papermaking of  claim 1 , wherein at least one of the plurality of first weft yarns and the plurality of second weft yarns include a first yarn having a first diameter a second yarn having a second diameter and a third yarn having a third diameter. 
   
   
       8 . The fabric for papermaking of  claim 7 , wherein at least one of the plurality of first warp yarns, the plurality of second warp yarns and the at least one binder warp yarn pair include a warp yarn having a diameter different than the first diameter, the second diameter and the third diameter. 
   
   
       9 . The fabric for papermaking of  claim 1 , wherein the warp yarn and the weft yarns include at least one of a monofilament yarn and a twisted pair yarn. 
   
   
       10 . The fabric for papermaking of  claim 1 , wherein the fabric is fabricated using a loom having at least three warp beams.
