摘要:
A woven slide fastener stringer comprises a binding thread system extending along a row of continuous coupling elements and fixing the latter to a longitudinal tape edge portion of a woven stringer tape. The binding thread system includes a warp thread extending through a space defined in the coupling element row and underlying the upper legs adjacent to the coupling heads of the coupling elements, and a weft thread having first loops interlaced with the longitudinal tape edge portion and second loops each overlying the upper leg of one of the coupling elements in transverse relation adjacent to the coupling head and underlying the warp thread at positions one on each side of the upper leg, whereby the upper legs are sandwiched between the warp and weft threads.

Each of the carrier tapes of a slide fastener include respective pairs of superimposed layers or plies of highly oriented polymer through which stitching threads are secured to attach coupling elements to each tape. The molecular orientation of each of the superimposed layers is at an oblique angle to the inner edge of the tapes with the orientation of one layer being transverse to the orientation of the other layer to prevent tearing of the stitches from the tapes.

A slide-fastener element of the monofilamentary-coil type is held in position on a stringer tape, woven from a set of warp threads and a continuous weft thread, by a core traversing the turns of the coil, the core being anchored to the tape by the weft thread which is interwoven with a first set of ancillary warp threads above the coil and with a second set of ancillary warp threads below the coil.

There is provided a slide fastener comprising a pair of opposed carrier tapes and rows of interlocking fastener elements mounted thereon. Each tape consists of a warp-knitted structure having wales of warp stitches connected coursewise by laid-in weft threads and alternated with grooves wider than said wales. These grooves are substantially filled with reinforcing warp threads to attain dimensional stability of the tape particularly at the longitudinal edge thereof along which the fastener elements are secured.

The invention provides a continuous chain of two rows of linking components for the making of slide fasteners out of two rows each consisting of a thread shaped into a spiral inside the whorls of which a longitudinal cord or strand is positioned, the improvement being that the said cord or strand is placed in an intermediate position in the width of each row by assembling the two corresponding rows while causing the linking components of each row to penetrate more deeply between the whorls of the other, in order to push back the length-ways inside cord or strand in the latter row, thereafter these two rows are fixed onto two supporting tapes by means of lines of stitching, the stitches of said lines being inserted inside the free spaces between the cord or strand inside each row and the portions connecting the successive whorls thereof.

The carrier tape in an otherwise conventional slide fastener stringer having coupling elements formed from a continuous length of a plastic filament is replaced by another length of plastic filament bent into repeating units having each the shape of a meander, a figure-eight, and the like. Each unit has two bend portions and two connecting portions of which one connects the bend portions, and the other one connects the unit to an adjacent unit. The bend portions are arranged in two rows parallel to the row of coupling elements, one or two coupling elements being fastened to an adjacent bend portion by sewing stitches, by adhesive, or by welding. The carrier of plastic filament is more durable than any tape and is readily shaped to hold the coupling elements in an arcuate row of small radius of curvature.

A separation portion having weakened tensile rupture strength of an element having tensile rupture strength reduced to 40 N or below is formed in a range of a first fixing portion of a first leg portion to a second fixing portion of a second leg portion via a coupling head portion, in at least a part of elements of the slide fastener. With this arrangement, when excessive lateral pulling force is applied to the slide fastener, cleavage lateral pulling force that causes cleavage of the slide fastener can be reduced. By adjusting tensile rupture strength of the elements, cleavage lateral pulling force of the slide fastener can be set within a predetermined range.

A continuous-coil type waterproof slide fastener includes two support tapes each having opposing first face and second face, two rows of coupling elements respectively formed of a continuous length of monofilament and respectively secured to along the inner longitudinal edge of the second face of each of the two support tapes, a high polymer elastic member bonded to the vertical wall of the inner longitudinal edge of each support tape and transversely extending from the vertical wall of the inner longitudinal edge to a predetermined distance, each high polymer elastic member further having a covering portion on the inner longitudinal edge of the second face of the associating support tape and a filling portion penetrates into inner chinks in the associating row of coupling elements, and a fluid impervious film covered at least on the first face of each support tape and the associating high polymer elastic member.
摘要:
A liquid-tight slide fastener, wherein a pair of right and left coil-like coupling element rows, through which a core thread is respectively passed, is attached by sewing along opposing side edges of a pair of right and left fastener tapes, the fastener tapes having a liquid-tight layer on one surface thereof, and the core thread is coated with a water repellent agent or oil repellent agent. Consequently, even if water or oil invades into a space portion in the coupling element rows through a joint portion in the liquid-tight slide fastener, the core thread repels the water or oil, thereby blocking a further invasion of water or oil, and exerting excellent water repellency or oil repellency without provision of a water stop flap.
