Abstract
In a single-layer papermaking woven fabric of more than four shafts, auxiliary wefts each having a smaller diameter than that of the primary wefts are disposed between each of the primary wefts. Each of the auxiliary wefts is woven once into a repeating unit of a texture by a warp. Each auxiliary weft is placed by at least two other warps extending above two adjacent primary wefts. The auxiliary wefts are pushed or urged upwardly thereof by these at least two other warps in order to form a flat papermaking surface of the fabric, whereby wire marks on a paper are reduced.
