There is provided a slide fastener. A pair of fastener element rows are respectively sewn to opposing tape side edge portions of a pair of fastener tapes with sewing threads. Each of the fastener element rows has a plurality of fastener elements. A slider is configured to engage and disengage the pair of fastener element rows. The pair of fastener tapes and the pair of fastener element rows are colored in different colors. The slide fastener is used such that the fastener element rows are at a back side. A width dimension of a gap between the pair of fastener tapes is set to be 10 to 25% of a width dimension of the pair of fastener element rows that are engaged with each other. The color of the fastener element rows is visible through the gap from a front side of the slide fastener.

In a Y bar for forming coupling elements, an opening angle of a pair of right and left leg parts is narrower than that of the ordinary ones. Plural bent portions, which are bent inward, are formed successively in an extending direction of the leg parts in a range from a crotch part toward pawl parts at front ends of the leg parts. The gap between the pawl parts are narrowed gradually from proximal ends to front ends thereof. Bulging portions are provided on outer side surfaces of the crotch part. Thus, the stabilization of the posture of a metallic coupling element, which is obtained by cutting the Y bar, at the time of mounting, strength of the coupling element and stabilization of the mounting posture of the coupling element to the fastener tape can be improved.

A colorful fastener tape for a slide fastener chain and a fastener stringer comprising such a fastener tape have an ornamental portion arranged along an inner longitudinal edge of the fastener tape and formed by multicolored yarns. A multicolored cord or a number of multicolored yarns are woven or knitted into the fastener tape 1 along the inner longitudinal edge to produce a thickened reinforced section, thus producing an ornamental portion such as of rainbow colored. Fastener elements of various types may be fitted to the reinforced section of the fastener tape of the a fastener stringer, thus the fastener stringer has a beautiful ornamental portion. When multicolored yarns are used for several warps or warp knitting yarns located adjacent to the reinforced section, a broadened ornamental portion can be produced to enhance the color effect of the fastener stringer that may be used for a dress to improve its color effect.
摘要:
A plastic separable fastener strip, and assembly of such strip with a substrate, and a method of attaching such strip to a substrate, comprising the provision of and utilization of fusible ribs on the base surface of the fastener strip to provide a bonding layer for bonding the strip to the substrate. Reducing the ribs into fusible condition without heat distortion of the remainder of the fastener strip and without heat distortion or damage of the substrate, provides a bonding layer when the fused ribs of the fastener strip are pressed together with the substrate. A simple apparatus and method are provided for effecting the bonding by fusion of the fusion ribs.

A slide fastener is disclosed including mounting tapes each having a warpless area or a void area formed in them near their adjacent edges. Coupling elements are secured onto the edges of the mounting tapes and plugs of material interconnecting the legs of each coupling element extend through the void area or warpless area of the mounting tapes. Interconnecting straps are also formed in the warpless areas linking each adjacent pair of the coupling elements.

A row of fastener elements for a slide fastener comprises a continuous spiral-shaped thread having a varying pitch, each whorl of the spiral thread having two legs which are substantially superimposed, and each whorl being separated from each other whorl, each whorl having at a first end portion thereof a deformation to serve as a tooth of a fastener element. In such a construction, the connecting sections between the successive whorls, opposite the teeth, each have a respective bend facing towards the teeth and the totality of said bends forms a series of notches along the corresponding longitudinal edge of the row of fastener elements. When the row of fastener elements is secured by stitching onto a backing tape, the stitching consists of two parallel longitudinal rows, one of said rows being at an intermediate point in the space between the teeth and the connecting sections, preferably close to the connecting sections, and the other being along the edge of the row of fastener elements opposite to the teeth and disposed inside the notches. Advantageously, the stitching is double chain-stitch made with two needles, the chains being positioned over the end of the whorls opposite to the teeth.
摘要:
A multifilament yarn composed of multiple filaments as thin as 0.5 to 1.5 dTex is used for all warp knitting yarns (1, 2) and warp weaving yarns (21 to 35-N) of a tape main body (A). As for an exposed portion on a side of a coupling head of each element covered with multiple fixing yarns (11, 11), when it is assumed that a distance from a front end of each coupling head (Eh) to an inside face of a connecting portion (Ec) is (a) while a dimension of a covered portion of an element (E) covered with the fixing yarns (11, 11) in a direction of a leg portion (El) thereof is (b), a value of a ratio (b/a) is larger than 1/2 and 4/5 or less. As a consequence, it is possible to obtain a knitted/woven concealed type slide fastener in which fastener elements are attached strongly in a stable manner, and even if a strong lateral force is applied to the slide fastener during usage, a coupling portion of a fastener element row is difficult to be seen from outside, the knitted/woven concealed type slide fastener being thin and plastic.

In a Y bar for forming coupling elements, an opening angle of a pair of right and left leg parts is narrower than that of the ordinary ones. Plural bent portions, which are bent inward, are formed successively in an extending direction of the leg parts in a range from a crotch part toward pawl parts at front ends of the leg parts. The gap between the pawl parts are narrowed gradually from proximal ends to front ends thereof. Bulging portions are provided on outer side surfaces of the crotch part. Thus, the stabilization of the posture of a metallic coupling element, which is obtained by cutting the Y bar, at the time of mounting, strength of the coupling element and stabilization of the mounting posture of the coupling element to the fastener tape can be improved.
