Abstract
A multilayer papermaker's fabric includes: a first set of machine direction yarns; a top set of cross machine direction yarns interwoven with the first set of machine direction yarns; and a bottom set of cross machine direction yarns interwoven with the first set of machine direction yarns. The first set of machine direction yarns, the top set of cross machine direction yarns, and the bottom set of cross machine direction yarns are interwoven in a repeat pattern in which each of the machine direction yarns passes below at least two nonadjacent bottom cross machine direction yarns, in which each adjacent pair of machine direction yarns passes below a common bottom cross machine direction yarn to form side-by side bottom knuckles, and in which machine direction yarns adjacent to and sandwiching the adjacent pair of machine direction yarns forming the side-by-side bottom knuckles pass over a top cross machine direction yarn positioned substantially directly above the bottom cross machine direction yarn under which the bottom knuckles are formed such that a phantom float is formed on that top cross machine direction yarn.
