Multi-layer fabric
First Claim
1. A fabric comprising:
- a first layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven therewith;
a second layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven therewith; and
a plurality of pairs of first type of binder yarns for binding the first layer and the second layer together which are interwoven therewith so as to be (i) an integral part of the first layer and contribute to a structure thereof, and (ii) a non-integral part of the second layer and not contribute to a structure thereof, each first type pair having a first binder yarn and a second binder yarn;
wherein during a repeat pattern the first binder yarn of a first type pair is integrally woven with the yarns of the first layer and passes over outer surfaces of two non-consecutive yarns in the second layer.

Abstract
A fabric having top and bottom layers, with each layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven together. The fabric includes pairs of binder yarns that bind together the top and bottom layers. The binder pairs are interwoven so as to be an integral part of the first layer and contribute to a structure thereof. The binder pairs are a non-integral part of the second layer and do not contribute to a structure thereof. During a repeat pattern, at least one of the two binder yarns of a binder pair is integrally woven with the yarns of the first layer and passes over outer surfaces of two non-consecutive yarns in the second layer. As a result, a “double knuckle” binding structure may be formed which improves integrity of the resulting composite fabric by reducing the length of the binder yarn path through the fabric.

25. A fabric for use in fabricating paper, said fabric comprising:
-
a first layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven therewith;
a second layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven therewith; and
a plurality of pairs of binder yarns for binding the first layer and the second layer together which are interwoven therewith so as to be (i) an integral part of the first layer and contribute to a structure thereof, and (ii) a non-integral part of the second layer and not contribute to a structure thereof, each pair having a first binder yarn and a second binder yarn;
wherein the first binder yarn of a pair passes in-between only two consecutive first layer yarns and two consecutive second layer yarns at a given location within a repeat pattern, and wherein the second binder yarn of the pair passes in-between only one first layer yarn and one second layer yarn at a given location within the repeat pattern. - View Dependent Claims (26, 27)
