Abstract
Abstract A slide fastener stringer tape comprising a major region made of a knitted fabric with an open, net-like texture, and a relatively narrow scoop-carrying region made of a warp-knitted fabric. The major tape region is longitudinally subdivided into several subregions of progressively finer mesh size from the one lying along one of its longitudinal edges to the one lying along the other longitudinal edge. The scoop-carrying region is arranged next to and along the finest mesh subregion of the major tape region, for supporting thereon a row of scoops of any desired type.
