Abstract: A slide fastener assembly has a net joining structure which includes a pair of warp-knitted adapters having a number of rectangular meshes defined by a plurality of warp cords and a plurality of weft threads. Each adapter has a net transition region including a plurality of longitudinal portions having meshes of varying sizes arranged for easy connection to one of the confronting edges of a net structure and for taking up and distributing lateral tension uniformly over the length of the slide fastener stringer supported by and between a pair of web regions of the adapter. The stringer is sewn to the web regions by at least one row of sewing stitches extending in and along a longitudinal groove in each of the web regions.
