Abstract
Abstract A velvet-type or snap-together fastener web comprises a warp-knitted ground structure and series of interlooped loops disposed in at least every other wale, each loop including a pair of mushroomed stems projecting from the wale at each course. To produce such a fastener web, a double-faced fabric is knitted on a Raschel warp knitting machine, and is separated into a plurality of strips by dissolving transversely spaced water-soluble threads in the fabric. Each strip is divided into front and back fabric webs by severing thermoplastic thread portions therebetween, leaving a multiplicity of raised stems on each fabric web. The raised fabric stems are then heated to mushroom their ends.
