Abstract
The present invention is directed to a fiber cement felt comprising repeat units, each of which includes top, middle, and bottom machine direction yarns and cross-machine direction yarns interwoven with the top, middle, and bottom machine direction yarns in a predetermined weave pattern. The top, middle, and bottom machine direction yarns may comprise effect yarns and linear yarns without the need for a batt layer.
Claims22
A fiber cement felt comprising:
- a base fabric comprising repeat units, each of which includes a plurality of top, middle, and bottom machine direction (MD) yarns and a plurality of cross-machine direction (CMD) yarns interwoven with the plurality of top, middle, and bottom MD yarns in a predetermined weave pattern,
- wherein the plurality of top, middle, and bottom MD yarns comprises a plurality of effect yarns and a plurality of linear yarns,
- wherein at least some of the top MD yarns are effect yarns, and at least some of the bottom MD yarns are effect yarns;
- and
- wherein at least some of the effect yarns in the plurality of middle and bottom MD yarns are woven in pairs with the linear yarns.
