Abstract
A fiber cement felt includes a fabric and a batt layer. The fabric includes: a set of fine top machine direction yams; a set of coarse bottom machine direction yarns; and a set of fine cross machine direction yams interwoven with the top and bottom machine direction yams in a plurality of repeat units. The batt layer overlies and is attached to the set of top machine direction yams of the fabric. The fineness of the yams of the top machine direction yams and the cross machine direction yams can improve the surface achieved with other fiber cement felts
