Description

Zipper belt

Original application numbers of the present case divisional: CN 201921646645.7; application date: 2019.09.29, respectively; the patent name: a zipper tape and a zipper tape knitting machine.

Technical Field

The utility model relates to a weave technical field, in particular to zipper strip.

Background

With the rapid development of the technology, since the zipper has the advantages of convenient opening and closing and durability, the zipper is widely used, for example, the zipper is used for ready-made clothes, leather bags, sleeping bags, tents and the like, and the zipper mainly comprises paired mutually-engageable zipper teeth and sewn cloth belts at two sides for use; the types of the slide fastener can be roughly classified into a metal slide fastener, a nylon slide fastener and a plastic steel slide fastener according to the material of the zipper teeth. Although the zipper has the advantage of convenient use, the zipper has the defect of being limited to be linear in processing or using occasions, namely, the zipper is difficult to form if the zipper is required to be processed by sewing a curve or an arc; especially metal and plastic steel zippers, because the zipper teeth are shaped and the bending and stretching degrees are limited, the defects that the zippers and clothes are uneven and are arched outwards are easy to appear after processing. Aiming at the defect, the traditional technology is that when the zipper is sewn, a plurality of gaps are cut on zipper cloth belts on two sides of the zipper by scissors so as to increase the elongation of the zipper belts; in the prior art, a special weaving technology is adopted to increase the scalability of a zipper strip. Chinese patent No. 01223244.0 entitled "improvement of fastener tape" discloses "an improvement of fastener tape including a long continuous element and a tape connected to one side, a non-tape-sewn portion of the tape being knitted with a stretch yarn, which can be stretched and expanded. Chinese patent No. 200410002476.5 entitled "fastener tape" discloses a fastener tape "having a positive wrinkle state after fastener elements are mounted in a state where the fastener element fixing edge portion is recessed and curved with a main body slightly undulating," after being woven or knitted outside a core thread in one fastener element fixing edge portion and at least part of constituent yarns extending in the warp direction adjacent thereto have a higher elongation recovery rate than all other constituent yarns and core threads extending in the warp direction. Thus, a woven or knitted fastener stringer "capable of securing the straightness after the fastener tape is sewn to the target clothes can be formed. The zipper belt knitting machine in the prior art mainly comprises a yarn guide device, a knitting device, a driving device and a dragging device, and the improvement on the yarn guide device and the knitting device can manufacture a novel zipper strip, but the structure is complex and the modification cost is large. To this end, chinese patent documents: CN201120149800.1 zipper tape knitting machine and the zipper tape knitted by the same, which discloses a yarn guide device, a knitting device, a driving device, a dragging device, wherein the dragging device comprises a plurality of dragging shaft assemblies, each dragging shaft assembly comprises a dragging shaft and a group of dragging wheels fixedly connected to the dragging shaft, each dragging wheel comprises a vertical positioning surface and a conical surface, the zipper tape is wound on the conical surface, and one side of the zipper tape is abutted against the vertical positioning surface. The zipper belt manufactured by the zipper belt knitting machine comprises one side for mounting zipper teeth and the other side for sewing, wherein the other side for sewing the zipper belt is wavy. Meanwhile, the utility model discloses a tow band pulley has the conical surface, just can exert progressive tensile force to the zipper area simultaneously at the in-process of dragging the zipper strip, thereby make the zipper strip produce the effect of wave fold, the zip fastener that possess wavy sewing limit when sewing the target clothing, although can absorb the shrink that some produced when sewing makes the good zip fastener level than conventional, but because the weaving knitting line of one side of its whole zipper strip installation chain tooth and the other side of sewing is isometric, the shrink size problem that should have wavy zipper strip and sewing needs has not been solved by essence, only draw down the range that the outward arch of the shrink size that will be needed to make up because of the wavy after sewing zipper strip and cloth etc. because of the wavy is balanced, what the zip fastener arch out after final zipper strip is made is not protruding to show at local big hunch out but is balanced to whole many places trace, the problem that the zipper belt is well knitted and then the zipper is arched due to sewing shrinkage of the zipper belt knitting can not be effectively solved when the traditional zipper belt knitting machine is knitted and manufactured.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a rational in infrastructure, can eliminate the zip fastener because of making up the size problem that the shrink produced, zip fastener and cloth, leather etc. make up the smooth and docile zipper strip of whole zip fastener after.

In order to solve the technical problem, the utility model discloses take following scheme: the zipper tape comprises a zipper tape body, wherein the zipper tape body comprises one side provided with zipper teeth and one side sewn with fabric, the length of the edge of one side of the zipper tape body sewn with the fabric is greater than that of one side provided with the zipper teeth, and the total length of warp yarns of one side of the zipper tape body sewn with the fabric in the length direction of the edge is 1% -10% longer than that of the warp yarns of one side of the zipper teeth in the length direction of the edge.

Furthermore, the length of the edge of one sewn side of the zipper tape body and the fabric is 1cm-5cm longer than that of the edge of one side provided with the zipper teeth.

Furthermore, one side of the zipper tape body, on which the zipper teeth are mounted, is provided with a reinforcing rib.

Furthermore, the reinforcing rib is wrapped in yarn on one side of the zipper tape body where the zipper teeth are installed.

Furthermore, the total length of the warp yarns of one edge of the zipper tape body sewn with the fabric along the length direction of the edge and the total length of the warp yarns of one edge of the zipper teeth mounted along the length direction of the edge gradually become longer from one edge of the zipper teeth mounted to one edge sewn with the fabric.

By adopting the technical scheme, the beneficial effects of the utility model are that: the zipper is manufactured by making the outer diameter length of the edge of the zipper tape body where the zipper teeth are installed and the outer diameter length of the edge of the side where the zipper teeth are sewed with the fabric different, so that the unit length of the side where the zipper tape body is sewed with the fabric is larger than that of the side where the zipper teeth are installed, namely, the side where the zipper tape body is sewed with the fabric is longer than that of the side where the zipper teeth are installed, so that the side which is longer than the side where the zipper teeth are installed and is sewed with the fabric is in a long arc shape, further, when the zipper is sewed to target clothes through the zipper tape, the long arc shape longer than the side where the zipper teeth are installed and the side where the fabric is sewed can absorb the shrinkage generated during sewing, the size problem of the zipper caused by sewing shrinkage can be completely eliminated, the sewed zipper tape and clothes are smooth and fit, the structure is reasonable, the integral zipper is smooth and fit after the zipper is sewed with cloth, leather and the like, can be widely popularized and applied.
