Slide fastener includes a pair of waterproof stringers including a pair of woven and/or knitted fastener tapes, a pair of coil elements respectively secured to opposing side-edge portions of the pair of fastener tapes, and waterproof films respectively overlaid via adhesives on tape top surfaces of the fastener tapes of the pair of fastener tapes, and a slider that moves forward to engage the pair of coil elements and moves rearward to disengage the pair of coil elements. The adhesive penetrates into a structure of the fastener tape such that the waterproof film and the fastener tape are in direct contact at least partially.

A slide fastener includes a pair of waterproof stringers comprising a pair of woven and/or knitted fastener tapes, a pair of coil elements respectively secured to opposing side-edge portions of the pair of fastener tapes, and waterproof films respectively overlaid via adhesives on tape top surfaces of the fastener tapes of the pair of fastener tapes, and a slider that moves forward to engage the pair of coil elements and moves rearward to disengage the pair of coil elements. Each of the waterproof films has a film edge positioned over a space between the opposing side-edge portions of the pair of fastener tapes, the film edge supported by a supporting portion made of the adhesive solidified, the supporting portion partially occupying the space between the opposing side-edge portions of the pair of fastener tapes, and the supporting portion having a thickness greater than a thickness of the film edge.

Provided is a fastener stringer attachment structure which can provide an attractive pants silhouette, improve the fit of the pants, and furthermore, reduce the manufacturing cost of the pants by reducing the number of superposed fabrics at a side edge section of a lower front bodice. A fastener tape of a fastener stringer is sewn with a sewing thread to the upper surface of a lower side fabric so that a fastener element of the fastener stringer is positioned inside an end section of the lower side fabric, and a portion of the sewing thread positioned over the fastener tape is in contact with the upper surface of the fastener tape.

Woven and knit substrates having juxtaposed notches with finished edges are disclosed. Such substrates can be used as opposed fastener tapes and fastener elements can be formed, woven, or otherwise added to the opposed fastener tapes in a known fashion. The notched fastener tapes permit the resulting slide fastener to be curved in-plane without buckling either of the opposed the fastener tapes out-of-plane. The finished edges maintain structural integrity of the woven or knit substrates, in stark context to prior art substrates having cut notches. Also disclosed are panelized substrates having curved apertures and incorporating disclosed slide fasteners.

A knitted fastener stringer has a chain stich yarn disposed on the innermost edge wale furthest from the tape body portion of an element attaching portion is the thickest of all the chain stich yarns used in a fastener tape. This enables a distance of a gap formed between left and right fastener tapes to be smaller when a slide fastener is formed by two knitted fastener stringers.

There is provided a slide fastener stringer. A substrate tape includes a first main side having a rough surface structure perceptible to the eye and/or the touch and a second main side opposite to the first main side. A gripping member is affixed to a longitudinal edge of the first main side of the substrate tape. A cover sheet is made of an artificial flexible material and has a 5 top surface provided with a predetermined design and a bottom layer made of a thermoformable material having a predetermined thickness. The bottom layer is attached to the second main side of the substrate tape such that the surface structure of the second main side of the substrate tape is not perceivable through the cover sheet.

Stringers without fastener tape have continuous fastener elements and have element fixing members wherein the fastener elements are sewn together by a sewing thread. The element fixing members are inserted between upper and lower leg sections of the fastener elements. The sewing thread comes in contact with and straddles the upper and lower leg sections of each fastener element and pierces the element fixing members between the fastener elements. As a result of such stringers without fastener tape, the fastener elements can be held and the weight and cost of an article with a slide fastener can be reduced.

Such substrates can be used as opposed fastener tapes and fastener elements can be formed, woven, or otherwise added to the opposed fastener tapes in a known fashion. The notched fastener tapes permit the resulting slide fastener to be curved in-plane without buckling either of the opposed the fastener tapes out-of-plane. The finished edges maintain structural integrity of the woven or knit substrates, in stark context to prior art substrates having cut notches. Also disclosed are panelized substrates having curved apertures and incorporating disclosed slide fasteners.

A fastener element has a central land portion and first and second bulging portions bulging from the central land portion toward the tape front surface side and the tape rear surface side in the element thickness direction. The first and second bulging portions respectively have a bulging end surface facing to the element thickness direction. The bulging end surface has a quadrilateral base end surface which is long in the element length direction and a tapered protrusion end surface protruding from the base end surface in the element width direction. Thus, it is possible to make the fastener element look like a single-sided metal element and to make a slide fastener which is formed by using the fastener elements lighter than a conventional slide fastener having single-sided metal elements.

A zip includes: a pair of stringer tapes, each of which supports a row of teeth; the teeth on the two tapes being mutually opposing and capable of interdigitation thereby to fasten one stringer tape to another; a slider, adapted to move along and whose motion is guided by the rows of teeth, the slider being adapted to cause interdigitation of the teeth as a result of motion along the teeth in a first direction, and to disconnect the teeth by motion along the teeth in a second direction; wherein the first and second stringer tapes are formed of a matrix of threads interspersed with a waterproof material.
