Abstract
In a papermaking single-layer broken-twill woven fabric having a running surface formed of long crimps of wefts, auxiliary wefts having a smaller diameter than primary wefts are disposed between primary wefts. The auxiliary wefts are disposed over warps at locations where one of two adjacent warps located between the two wefts intersect by extending from either the paperside or from the running side of the preceding primary weft toward the opposite side of the succeeding primary weft. Every auxiliary weft which is woven into the texture at least once in a repeating unit, thereby forms a flat papermaking surface.
