Definitions

  • This invention relates to slide fasteners and particularly to stringer tapes of a warp-knitted structure for mounting thereon rows of interlocking fastener elements.
  • Warpknitted tapes for use in the field of slide fasteners or zippers.
  • Warpknitted tapes of the known type are basically 'con structed with longitudinally extending chain stitches which form a multiplicity of wales and transversely extending lapping threads laid into connect the wales coursewise.
  • the knitted tapes are known to be inferior to woven fabric tapes inrespect of the qualities of mechanical strength and dimensional stability; that is, they have the inherent problem of stretch which occurs warpwise or weftwise when they'are subjected to external stresses exerted in normal use of the slide fastener. I
  • FIG. 1 is a diagrammatic view illustrating the construction of a warp-knitted fastener tape provided in accordance with the invention
  • FIGS is a trans've'rse cross-sectional view of a modification of the warp-knitted tapeof FIG. 1.
  • FIG. 1 An inspection of FIG. 1 will show that the chain stitch 13 has a closed lap 13a alternating with an open lap 13b in each course of the knitted structure and that the lapping threads 14 consist of two different groups of lapping threads 14a and 14b having their respective lapping points or U-tums 14a and 14b disposed in alternate'courses, the arrangement being that the resulting web portion 11 has a double-faced knit structure in which the wales W project symmetrically from both surfaces of the tape.
  • This is better depicted in FIG. 2, and this double-layer knit system renders the tape 10 physically rugged and dimensionally stable as required in the art of slide fasteners.
  • a reinforcing core member 16 inserted centrally between adjacent wales W and W and extending lengthwise of the tape 10 so as to cause the marginal edge portion 12 to become more swollen and projected uniformly on both sides of the tape 10.
  • the lapping threads 14c serving to connect the marginal edge portion 12 with the web portion 11 are preferably stronger and greater in denier than the remaining lapping threads 14.
  • connecting threads 17 for separably connecting adjacent ones of a plurality of tapes 10 widthwise.
  • This connecting thread 17 may be for example dissolvable in water so that the tapes 10 may be separated to individual widths when they are treated with water as in dyeing process at the finishing stage of the slide fastener manufacture.
  • FIG. 3 illustrates a modification of the warp-knitted fastener tape 10 which has been described with reference to FIGS. 1 and 2.
  • This modification is characterized by the provision of a double-layer knit structure only at limited areas of the web portion 1 1 immediately adjacent the swollen marginal edge portion 12, while the remaining web areas are constructed with a singletheir upper and lower legs Ea and Eb mounted astride of the marginal edge portion 12 in the properly aligned position and in parallel to the plane of the tape web.
  • the fastener elements E can maintain their proper operative posture over extended lengths of time against severe stresses applied to the slide fastener in use.
  • a warp-knitted tape for a slide fastener which comprises a web portion and a marginal edge portion extending longitudinally of the web portion and adapted to carry a row of coupling elements each having a pair of spaced-apart legs extending in a transverse direction to said row of coupling elements, said web portion comprising chain stitches forming a plurality of longitudinally extending wales and at least two different groups of transversely extending lapping threads laid in to connect said wales coursewise, and said marginal edge portion comprising chain stitches forming a plurality of longitudinally extending wales and two different groups of tricot stitches extending across and interknitted with said wales whereby said marginal edge portion is thickened and projects symmetrically with respect to the plane of the tape to accommodate secur- 4 ing said row of coupling elements to the marginal edge portion with the legs of the elements mounted astride of said marginal edge portion.
  • a warp-knitted tape as defined in claim 1 in which a reinforcing core member 1 is inserted centrally into said marginal edge protion.
