Abstract
A multi-layer fabric which may be utilized in a papermaking process. Such fabric has a first layer of machine direction (MD) yarns, a second layer of MD yarns and a first system of cross-direction (CD) yarns having first binder yarns weaving a first contour pattern and second binder yarns weaving a second contour pattern different from the first contour pattern. The first binder yarns and the second binder yarns are each intrinsic to the first layer and each bind with the second layer. Moreover, the binder yarns each weave in sequence in the first layer more than once in a pattern repeat of the fabric. The binder yarns also weave plural contour patterns in the first layer in the weave pattern repeat.
