Abstract:
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.
Abstract:
A double sided nylon sandwich mesh fabric zipper and slider assembly includes coil strips being left handed and right handed plastic coils each having a center cord and a series of interlocking teeth, each tooth having a tooth head and a tooth body so configured that the tooth heads are respectively interlockable with the tooth heads of the teeth of the coil strips at the other zipper tape. The slider has C-shaped guide grooves to guide locking and unlocking positions horizontal movement of the teeth of the upper and lower coil strips, and a balance guide block configured to match with the configuration of the tooth heads, facilitating accurate alignment between the left and right teeth of the upper and lower coil strips and assuring smooth engagement and disengagement of the interlocking teeth.
Abstract:
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.
Abstract:
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.
Abstract:
The present invention provides a warp-knit slide fastener in which a fastener element row can be easily knitted into and attached stably and firmly on a fastener tape, and fastener elements of the fastener element row are not separated from each other due to pushing up of a fastener face.The successive fastener element row is knitted, simultaneously with knitting of the fastener tape, into a fastener element attaching portion at longitudinally side edge portion of the fastener tape, and is fixed by two wales or more of fixing chain stitch yarns. Respective needle loops of the respective fixing chain stitch yarns push respective element leg portions of the successive fastener element row from above toward a foundation structure. Respective sinker loop groups form a part of the foundation structure on which the successive fastener element line is disposed. Warp in-laid yarns are warp inserted through at least a part of sinker loops of the sinker loop groups while being intermingled. Heat contraction rates of all yarns forming the fastener element attaching portion are higher than that of yarns forming a fastener tape main body portion. After knitting, respective knitting yarns are heat contracted.
Abstract:
In a knit slide fastener in which a continuous fastener element row is knitted in a fastener element attaching marginal portion of each of fastener tapes simultaneously with the knitting of the fastener tape, the fastener element attaching marginal portion includes a plurality of parallel binding chain stitch yarns extending longitudinally of the marginal portion for holding the fastener element row to the marginal portion. One of the binding chain stitch yarns, which is adjacent to coupling heads of fastener elements, is larger in size than the remaining binding stitch yarns.
Abstract:
A knit slide fastener comprises: a warp-knit fastener tape having along one longitudinal edge a fastener-element-mounting marginal portion; and a row of continuous fastener elements knitted in the fastener-element-mounting marginal portion simultaneously with the knitting of the warp-knit fastener tape; the fastener-element-mounting marginal portion including anchoring chain stitches knitted of a plurality of parallel knitting yarns for pressing down successive legs of the continuous fastener elements, and a plurality of anchoring weft inlaid yarns laid in weftwise in a zigzag pattern and between the parallel knitting yarns of the anchoring chain stitches, the anchoring weft inlaid yarns being interlaced with the chain stitches.
Abstract:
A coiled slide fastener element made of a synthetic resin monofilament has a coupling head portion, which has an enlarged width by forming bulging portions so that firm coupling of a slide fastener can be realized.
Abstract:
In a woven slide fastener stringer of the type which comprises a row of successively interconnected elongated loops of a plastic filament woven into a longitudinal edge of a stringer tape woven of foundation warp and weft threads, and a pair of groups of upper and lower binding warp threads extending respectively over and under the loops and interwoven with the foundation weft thread, the improvements comprising a gap-filling warp thread extending parallel with and between an outermost one of the upper binding warp threads and the next adjoining upper binding warp thread and also between an outermost one of the lower binding warp threads and the next adjoining lower binding warp thread, and passing alternately over and under the foundation weft thread, thereby tensioning the latter thread to sink substantially halfway between the upper and lower legs of each adjacent pair of loops. Preferably, the outermost upper and lower binding warp threads are disposed in registry with each other to make the foundation weft thread lie substantially perpendicualr to the plane of the fastener stringer between the two outermost binding warp threads. The row of loops thus woven is stably secured in place against angular displacement and held at the proper pitch with respect to individual adjacent loops.
Abstract:
Disclosed is a woven slide fastener of the type in which fastener elements formed of a continuous monofilament in the shape of a coil are woven into a longitudinal side portion of a tape fabric at the same time that the tape fabric is woven. In order to improve element spacing stability and raise the bending and tensile strength, as well as the thrust-up strength, of a fastener chain, a weft thread at an element weave-in portion of the tape is so arranged as to alternately run over and under and intersect binding warp threads and coil-fastening warp threads.
