Definitions

  • the present invention relates to a slide fastener tape obtained by weaving or knitting and more particularly, to a slide fastener tape having a so-called positive pucker condition in which a fastener stringer, on which elements are mounted by strong stretching and various kinds of heat treatments, is slightly dented toward the element attachment side, and the slide fastener tape being integrated with object clothes by sewing such that the entire surface thereof is uniform and flat without weaving on its tape main body and its sewed surface by absorbing the aforementioned slight dent through contraction of the tape main body at the time of sewing.
  • fastener tape As for the slide fastener tape (hereinafter referred to as fastener tape), a plurality of elements, which are formed to mesh with mating elements, are mounted along a side edge thereof at an equal pitch and a slider is loaded on the element row. Then, upper and bottom stopper devices are attached to ends of the element row so as to produce a slide fastener of a predetermined length. After that, this slide fastener is sewed to clothes or various kinds of bags by sewing.
  • the fastener tape has a tape main body and an element attachment edge portion attached to a side edge of the tape main body.
  • this element attachment edge portion a core thread having a larger diameter than other warp yarns is knitted together along the longitudinal direction of the tape at the same time when the tape is knitted or woven in order to not only stabilize the attachment condition of the respective elements but also increase their attachment strength.
  • the element attachment edge portion in which the core thread is disposed has a smaller heat shrinkage than the tape main body.
  • the tape main body is contracted largely in the fastener tape after passing various of heat treatment processes, thereby likely producing an inverted pucker in which the element attachment edge portion is warped outwardly.
  • Japanese Patent Application Publication No. 59-51807 has proposed that a textured yarn is adopted as the constituent yarns for the tape main body in a fastener tape composed of double-sided knitting structure, and a core thread covered with a covering yarn continuous from the tape main body is disposed in the element attachment edge portion while the boiling water shrinkage ratio of the core thread is higher than that of the textured yarn.
  • Japanese Patent Publication No. 2002-209613 has disclosed a slide fastener tape comprising a tape main body produced by weaving and an element attachment edge portion in which a core thread is woven, wherein a foundation warp yarn used for the tape main body is composed of a textured yarn having a lower thermal shrinkage ratio than the other warp yarns, and the core thread has a multi-filament having a high boiling water shrinkage ratio while a warp yarn inside and adjacent the core thread is composed of a textured yarn whose boiling water shrinkage ratio is higher than that of the foundation warp yarn used in the tape main body and lower than that of the core thread.
  • this fastener tape has an inverted pucker condition in which the element attachment edge portion is slightly jumped outward and curved because of a difference in weaving structure between the tape main body and the element attachment edge portion. If dry thermal setting is applied to the fastener tape having such a structure for a short time, the contraction amount of the element attachment edge portion and the contraction amount of the warp yarn disposed in the tape main body are hardly different and the contraction amount of the element attachment edge portion is slightly larger. Thus, the inverted pucker which is produced when weaving of the fastener tape is completed is eliminated so that entirely the fastener tape becomes linear.
  • the contraction amount in the fastener tape due to dying decreases in the order from the core thread to the warp yarn adjacent the core thread and the tape main body, so that the fastener tape turns into the positive pucker condition in which the side of the element attachment edge portion is dented inward like a bow.
  • bias occurs such that the tape main body turns into a waved condition.
  • the boiling water shrinkage ratio of the core thread in the element attachment edge portion of the fastener tape larger than the boiling water shrinkage ratio of the warp yarn inside and adjacent the core thread, the difference in thermal shrinkage between the element attachment edge portion and the tape main body is changed in steps. Thus, no step-like contraction behavior is generated between the element attachment edge portion and the tape main body. Because the element attachment edge portion in the fastener stringer keeps linear when this slide fastener is sewed to object clothes, the sewing processing can be executed accurately, and consequently, a beautiful product can be obtained, in which no waved state occurs in a longitudinal direction in the slide fastener after the sewing.
  • GB 681 438 discloses a fastener tape which can be either slightly concave or slightly convex. Nylon threads are used which lead to a positive pucker condition at the time of attaching the engagement elements after weaving.
  • GB 2 069 553 discloses a woven stringer tape of a sliding clasp fastener. Warp threads in spaced zones have a greater contractibility than warp threads in intermediate zones which consequently have a more relaxed construction than the spaced zones, thus permitting contraction during the sewing operation without producing undesirable undulations.
  • EP 1 224 883 is a fastener tape obtained by weaving in which the difference of thermal contraction coefficient between the various warp yarns is used to obtain a fastener stringer with less puckering, which can be linearly secured to a garment.
  • puckering is diminished or avoided due to differences of thermal contraction coefficient of the various yarns used in an ordinary weaving structure.
  • the present invention aims at avoiding any puckering due to differences in contraction resulting from the tension which occurs due to the sewing thread used for sewing a fastener chain to an object or a cloth.
  • a specific object of the present invention is to provide a woven or knitted slide fastener tape capable of obtaining a beautiful sewed product regardless of which the sewed product is hard or soft.
  • a slide fastener tape comprising: a tape main body formed by weaving or knitting and an element attachment edge portion in which a core thread is woven or knitted, wherein constituent yarns extending in a warp direction outside and adjacent the core thread in the element attachment edge portion have an elongation recovery ratio R against a stretching, which is obtained according to JIS L1096 and is higher than that of all other constituent yarns and the core threads extending in the warp direction according to claim 1.
  • the main body and element attachment edge portion in the fastener tape are pulled together strongly and particularly, the element attachment edge portion is pulled relatively strongly.
  • the element attachment edge portion and the tape main body are elongated together by a tension at the time when the elements are attached.
  • the element attachment edge portion approaches to its original length because the elongation recovery ratio R of the constituent yarns disposed outside the core thread in the element attachment edge portion is set larger than the elongation recovery ratio R of the constituent yarns extending in the warp direction of the tape main body.
  • recovery of its tape main body is small, thereby providing a positive pucker condition in which the side of the element attachment edge portion is dented and curved like a bow while the tape main body is waved.
  • the tape main body is flattened due to contraction which occurs at the time of sewing, so that the fastener tape is sewed in a condition that it is well adapted to the object clothes. That is, a beautiful product which does not suffer waving in the longitudinal direction of the slide fastener after sewing is obtained.
  • the elongation recovery ratio R at this time can be obtained by measuring respective yarn lengths according to JIS L1096 and using the following equation (1).
  • the elongation recovery ratio R of the constituent yarns disposed outside the core thread in the element attachment edge portion of the present invention is difficult to automatically determine because it is determined relative to that of the other constituent yarns.
  • the elongation recovery ratio R is preferred to be 85% or higher because the elongation recovery ratio R of the constituent yarns disposed outside the core thread in the element attachment edge section is easier to set to be higher than the other materials.
  • the elongation recovery ratio R of ordinary multi-filament or mono-filament is at most 80% even if it reaches its maximum.
  • L0 is an original yarn length
  • L1 is a yarn length when pulled under a predetermined tension
  • L2 is a yarn length after recovery under no tension
  • a tension test machine or an apparatus having similar performance is used for measurement of the yarn length based on JIS L1096, a tension test machine or an apparatus having similar performance. With an end of a test piece fixed with a clamp, an initial load is applied to the other end and marks are made at a position 20 cmk from a bottom end of the clamp in the test piece. Next, a load of 14.7 N (1.5 kgf) is applied gently and after leaving for one hour, the interval between the marks is measured. Next, the load is removed and the initial load is applied 30 seconds after and one hour after and then the interval between the marks is measured.
  • the elongation recovery ratio R is obtained according to the above-described equation (1) and three average values are calculated about 30 seconds after and one hour after.
  • the elongation recovery ratio R is preferred to be set smaller in the order from the constituent yarns in the element attachment edge portion extending in the warp direction outside and adjacent the core thread to the core thread and all the other constituent yarns extending in the warp direction in the tape main body. If the fastener tape is left under no load after it is stretched equally with such a structure, the constituent yarns in the element attachment edge portion extending in the warp direction outside and adjacent the core thread, the core thread and the tape main body try to return to their original lengths in this order. As a result, their elongation recovery behaviors are obtained without any difference in step among these yarns, thereby providing a positive pucker condition in which the element attachment edge portion is dented and curved like a bow. When the slide fastener is sewed to object cloth, contraction at the time of sewing is absorbed by the waving state of the tape main body, so that the sewing work can be carried out easily and accurately and a beautiful product can be obtained after the sewing.
  • the size of a single yarn having a high elongation recovery ratio R is set larger than the size of the single yarn in all the constituent yarns extending in the warp direction. If the size of the single yarn having the high elongation recovery ratio R is larger than the size of the single yarn in all the other constituent yarns extending in the warp direction, the recovery ratio after the elongation is increased. Even if the inverted pucker condition is conceivable until elements are mounted, it can be changed to a slight positive pucker condition securely after the elements are mounted.
  • Examples of a typical material for a yarn having a high elongation recovery ratio R include nylon and polycondensate of n-propanediol and terephthalic acid. If multi-filament yarn of polyester is employed for all the other constituent yarns extending in the warp direction in the tape main body except these yarns, it is preferable because a conceivable different can be provided to the elongation recovery ratio R between them.
  • a fastener tape obtained by weaving employing the textured yarn for all warps yarns used in the element attachment edge portion and tape main body is preferable because it prevents deviation in stitch.
  • the knit fastener tape does not always need to be of a textured yarn because there is no fear that their stitches may be deviated.
  • FIG. 1 shows an example of a woven fabric of a fastener tape according to a typical embodiment of the present invention. Although the weaving structure shown in this figure is expressed roughly for graphic representation, actually, this is composed of a tight structure.
  • the fastener tape 1 having this weaving structure is woven by means of a small-width weaving machine usually called needle weaving machine.
  • a yarn is reciprocated through an opening produced by the warp yarns, so that two yarns act as a pair of weft yarns 2 in a condition that they are doubled.
  • the pair of weft yarns 2 inserted laterally are expressed as a condition that yarns 2a, 2b doubled are set apart from each other in a vertical direction, actually, the yarns 2a, 2b keep in contact with each other.
  • a loop end formed at a return end of the weft yarn 2 entangles with a loop end of a weft yarn (not shown) which is to be formed next time with a latch needle (not shown), so as to form an ear section at a side edge of the fastener tape 1.
  • fastener elements 3 are attached as indicated with a phantom line in FIG. 2 .
  • the fastener tape 1 is comprised of an element attachment edge portion 4 on which fastener elements 3 are to be attached and which is located on an edge portion opposite to the ear section (not shown) formed by entanglement of the loop ends of the weft yarns 2, and a tape main body 5 which is stretched from the element attachment edge portion 4 to the ear section (not shown) on the opposite side.
  • the yarns 2a, 2b which compose the weft yarns 2 of this embodiment a fine textured yarn constituted of 330dTex polyester is employed.
  • nylon multi-filaments thicker than the other warp yarns 6c, 6d, 6e, ... 6m, 6n are disposed and two core threads 7a, 7b are disposed inside and adjacent the two warp yarns 6a, 6b.
  • the polyester textured yarns composing two pairs of warp yarns 6c to 6f, each composed of two yarns, are disposed inside and adjacent the core threads, thereby constructing the element attachment edge portion 4.
  • the multiple foundation warp yarns 6g, 6h, ... 6m, 6n are disposed in the tape main body 5 from its inside up to the ear section. These foundation warp yarns 6g, 6h, ... 6m, 6n are woven successively while each is composed of two yarns as a pair. Two narrow warp yarns 6o-1, 6o-2 disposed outside the two warp yarns 6a, 6b, disposed outside and adjacent the aforementioned element attachment edge portion 4, have a function of holding the configuration of the edge of the element attachment edge portion 4.
  • the entire organization except the core threads 7a, 7b is a plain weaving organization in which the warp and weft yarns are woven with two yarns of each as a pair.
  • the two warp yarns 6a, 6b having a high elongation recovery ratio R disposed in the element attachment edge portion 4 of the fastener tape 1 and outside of the attachment edge portion are composed of nylon multi-filament having a boldness of 470 Tex.
  • the two core threads 7a, 7b are composed of polyester made multi-filament of 560 dTex of gray yarn as a core thread and knit yarns of 267 dTex covering the circumference of the former.
  • the respective warp yarns 6c, 6d, ... 6m, 6n on the side of the tape main body of the element attachment edge portion 4 are composed of polyester textured yarns of 330 dTex.
  • the two warp yarns 6o-1, 6o-2 disposed most outside in the element attachment edge portion 4 are composed of polyester textured yarns of 235 dTex.
  • the warp yarns 6a, 6b disposed outside and adjacent the core threads 7a, 7b are not elongated by liquid pressure at the time of injection of the fastener element and in coloring process.
  • the elongation recovery ratio R of the two warp yarns 6a, 6b having a high elongation recovery ratio R is 94.3%, the elongation recovery ratio R of the warp yarns 6c, 6d, ...
  • the elongation recovery ratio R of the core threads 7a, 7b is 73.1%. That is, the elongation recovery ratio R decreases gradually in the order of the two warp yarns 6a, 6b disposed outside and adjacent in the element attachment edge portion, the core threads 7a, 7b and the warp yarns 6c, 6d,.. 6m, 6n disposed in the tape main body.
  • the above-mentioned core threads 7a, 7b have a boiling water shrinkage ratio of 15%, which is extremely larger than the other yarns, so that the thermal setting contraction is increased from conventional 5% to 7%.
  • the elongation recovery ratio R of the two warp yarns 6o-1, 6o-2 disposed most outside in the element attachment edge portion 4 is equal to the elongation recovery ratio R of the warp yarns 6c, 6d,... 6m, 6n disposed in the tape main body.
  • the core threads 7a, 7b are covered so as to surround a core material with a knit tube obtained by intersecting sinker loops each composed of multiple knitting yarns with each other like the core thread structure disclosed by, for example, Japanese Utility Model Application Publication No. 55-21605 .
  • gray yarn multi-filaments of polyester of 330 dTex ⁇ 2 are employed as the core thread and its boiling water shrinkage is set to as high as 15%.
  • the configuration of the fastener tape 1 changes as indicated in FIGs. 3A to 3E each time when it passes a predetermined heat treatment process. Consequently, when elements are attached by injection under a high temperature, a fastener stringer 8 is configured into a positive pucker in which the side of the element attachment edge portion 4 is slightly dented to produce a curved shape. Its slight waving condition is eliminated by contraction in the fastener tape generated when it is sewed to mating clothes so that a beautiful sewing configuration can be obtained easily.
  • the fastener tape 1 obtained in this way is dyed.
  • this dying usually, the fastener tape 1 is wound around a dying beam (not shown) and that beam is dipped into dying solution circulated in a dying machine and then, the fastener tape 1 is dyed under high temperatures. Therefore, unless the fastener tape is wound around the beam uniformly, no uniform dying can be obtained.
  • the fastener tape 1 having the pucker condition just after weaving is completed is subjected to the thermal setting under a dry hot condition temporarily. At this time, a uniform tension is applied to the fastener tape 1 to execute linear thermal setting so that uniform winding around the beam is secured.
  • this just woven tape is subjected to thermal setting under a dry hot condition of, for example, 180°C for a minute, as shown in FIG. 3B , although the core threads 7a, 7b are contracted, they are not contracted completely because the thermal setting processing time is short. Further, a difference in contraction between the element attachment edge portion 4 and the tape main body 5 at the time of thermal setting is quite small and bias in the element main body hardly exists visibly.
  • the fastener tape 1 is dipped into a high-pressure dying solution at 130°C and dyed for 40 minutes. Consequently, the element attachment edge portion 4 is contracted most and then, the core threads 7a, 7b are contracted next, so that a difference in contraction occurs between the element attachment edge portion 4 and the tape main body 5. As a result, as shown in FIG. 3C , a positive pucker condition becomes evident so that it is visually found that wave-like bias is generated in the tape main body 5 at the same time.
  • Fastener elements 3 are injection-molded under high temperatures subsequent to dying and then, are integrated with the element attachment edge portion 4 of the fastener tape 1. At this injection-molding time, the largest tension is applied to the element attachment edge portion 4 so that it is elongated. Although if the tension is released after the molding, the elongation in the element attachment section of the element attachment edge portion 4 is not recovered but that in the tape section between the elements is largely elongated or recovered.
  • the recovery from the elongation in the core threads 7a, 7b and tape main body 5 is small and because of the difference in elongation recovery ratio R, the warp yarns 6a, 6b disposed outside and adjacent the core threads 7a, 7b, the core threads 7a, 7b, and the warp yarns 6c, 6d, ... 6m, 6n disposed in the tape main body try to return to their original lengths.
  • the warp yarns 6a, 6b disposed outside and adjacent the core threads 7a, 7b are recovered to their original length most while the amount of the recovery in the warp yarns 6c, 6d, ... 6m, 6n in the tape main body is the smallest.
  • the element attachment edge portion 4 in a fastener chain 9 becomes linear as shown in FIG. 3D so that the waving in the tape main body 5 is evident.
  • a slider is loaded on the fastener stringer 8 and upper and bottom stopper devices are mounted.
  • this slide fastener is sewed to object clothes, although usually its sewing section is waved due to contraction by sewing, the slide fastener of this embodiment fits to the object clothes regardless of which it is hard or soft at the time of sewing because the tape main body 5 is in the waving condition. Consequently, not only the slide fastener can be sewed easily but also as shown in FIG. 3E , a product after sewing 10 can be completed beautifully. Particularly, this slide fastener is preferable for a soft object clothes.
  • FIG. 4 shows a modification of the fastener tape 1 obtained by weaving in the same way as the above-described embodiment.
  • This modification is achieved by modified hollow-weaving and although the organization of the core threads 7a, 7b to be woven into the element attachment edge portion 4 is the same as the above-described embodiment, the two warp yarns 6a, 6b having a high elongation recovery ratio R disposed outside and adjacent the same core threads 7a, 7b are arranged in parallel in the direction of the front and rear sides of a tape surfaces and the two warp yarns 6o-1, 6o-2 having a small diameter disposed most outside in the element attachment edge portion 4 are excluded from this embodiment.
  • a textured yarn composed of polycondensate constituted of n-propanediol having a high elongation recovery ratio R and terephthalic acid is employed for the warp yarns 6a, 6b having a high elongation recovery ratio R in the element attachment edge portion 4 like the above embodiment.
  • a textured yarn of polyester having a smaller elongation recovery ratio R than the warp yarns 6a, 6b is employed for the warp yarns 6c, 6d, ... 6m, 6n in the tape main body 5 like the above embodiment.
  • the elongation recovery ratio R of yarn (made by Asahi Chemical Industry Co., Ltd.) composed of polycondensate constituted of the aforementioned n-propanediol and terephthalic acid is 88% and the elongation degree is 36 to 37%, which are extremely larger than polyester and nylon 66.
  • FIG. 5 shows another modification of the above-described embodiment.
  • the element attachment edge portion 4 is formed as hollow-woven section and a large core thread 7 is inserted in this hollow-woven section.
  • Three warp yarns 6o, 6a, 6b composed of large nylon multi-filament having a higher elongation recovery ratio R than the other warp yarns 6c, 6d, ... 6m, 6n are disposed as yarns arranged most outside in the hollow-woven section. Polyester is used as material of the other warp yarns 6c, 6d,... 6m, 6n like the above embodiments.
  • the fastener stringer 8 after the elements 3 are mounted is formed to have a positive pucker condition in which the element attachment edge portion 4 is slightly dented, so that a product after the fastener stringer is sewed thereto can be finished beautifully.
  • two or three warp yarns 6a, 6b (6o) having a higher elongation recovery ration R than the other warp yarns 6c, 6d, .. 6m, 6n are disposed most outside in the element attachment edge portion 4. Therefore, the behavior of the fastener stringer which tries to return to its original configuration is unlikely to be affected by its peripheral organization so that its predetermined recovery amount becomes easy to obtain and thus, the positive pucker condition can be obtained securely.
  • FIG. 6 shows a second embodiment of the present invention.
  • a fastener tape 11 of this embodiment is a warp knit tape. Although this figure expresses the arrangement of the constituent yarns roughly, actually, they are knitted more tightly.
  • this fastener tape 11 is comprised of an element attachment edge portion 14 on which multiple elements 3 are to be attached at an equal pitch and a tape main body 15 to be sewed to object clothes (not shown).
  • chain knitting yarns 16a, 16b,.. 16m, 16n are disposed on all wales and a 0-0/3-3 weft yarn 12a is inserted into a needle loop of each of the chain knitting yarns 16a, 16b,... 16m, 16n successively.
  • One core thread 17 is disposed between the chain knitting yarns 16a and 16b in the element attachment edge portion 14 and the core thread 17 is knitted into and fixed in the element attachment edge portion 14 by intersecting this weft yarn 12a with the 3-3/0-0 weft yarn 12b on the front and rear surfaces.
  • the total size of the nylon-made multi-filament yarn 16p used in the present invention is 470 dTex and its elongation recovery ratio R is 94%.
  • the core thread 17 is produced by covering a core material 17a of polyester-made multi-filament yarn of three gray yarns of 560 dTex with a covering section 17 which is hollow-woven with a single polyester-made multi-filament yarn of 267 dTex and its elongation recovery ratio R is 78.8%.
  • a textured yarn composed of 330-dTex polyester-made multi-filament is employed for the chain knitting yarns 16a, 16b, ... 16m, 16n and the weft yarns 12a, 12b and its elongation recovery ratio R is 75.6%.
  • the chain knitting yarns 16a, 16b,... 16m, 16n and the weft yarns 12a, 12b of this embodiment utilize a small size yarn and organized in a knitting structure. Accordingly, the fastener tape 11 after knitting has an extremely excellent plasticity and adapts itself to a knit fabric or thin woven cloth easily. Further, because the above-described structure is adopted, a fastener stringer (not shown) after the elements 3 are attached has a positive pucker condition in which the element attachment edge portion 14 is slightly dented like the first embodiment, so that it adapts itself to an object clothes well. At the same time, it can absorb a contraction generated at the time of sewing sufficiently and consequently, a beautiful sewing product is produced.
  • FIG. 7 shows a modification of the second embodiment.
  • the nylon-made multi-filament yarn 16p of the second embodiment is excluded and a nylon-made multi-filament yarn having a high elongation recovery ratio is employed for the chain knitting yarn 16a disposed outside the core thread 17 of the two chain knitting yarns 16a, 16b disposed in the element attachment edge portion 14.
  • the physical property at this time is substantially the same as the second embodiment.
  • the chain knitting yarn 16a disposed most outside in the element attachment edge portion 14 is more than twice longer than the second embodiment.
