Patent number: 5669247Abstract: In an underwire brassiere, a generally inelastic and dimensionally stable two-bar warp knitted fabric is provided as a covering for the underwire. One set of warp yarns is knitted in a pattern of coursewise spaced stitches with extended underlaps and another set of warp yarns is knitted in a chain stitch pattern, collectively providing warpwise and coursewise stability and elongation resistance to the fabric. The run-in ratio of the two sets of warp yarns imparts a controlled coursewise inclination to the chain stitches enabling a predetermined degree of walewise elongation for better conformation of the fabric to the underwire in fabrication of the brassiere.Type: GrantFiled: August 28, 1996Date of Patent: September 23, 1997Assignee: Guilford Mills, Inc.Inventors: Phillip D. McCartney, Hilda E. Allen, James G. Donaghy

Patent number: 5628210Abstract: In a method for manufacturing a warp knitted fabric, the guides can also be displaced by one needle space (pitch) in addition to the overlap and underlap shog of the guide bar, so that the guides are not only selectively displaceable during the underlap shog, but also selectively during the overlap shog. A warp knitting machine for the purpose of carrying out the method comprises at least one thread system which consists of pattern threads laid in intermixed, varying patterns. These pattern threads have underlaps of n, n+1 and n-1 needle spaces and can produce a float and/or a twill. The number of pattern possibilities can be increased in this manner.Type: GrantFiled: April 24, 1995Date of Patent: May 13, 1997Assignee: Karl Mayer Textilmaschinenfabrik GmbHInventors: Kresimir Mista, Hans-Jurgen Hohne
