Description

  The present invention relates to a piping tape for use in clothing edge decorations.

  There is a technique called piping as one method of cleaning the cloth edge. Piping is usually done in a decorative manner, with a bi-folded bias tape placed between the front and back or two facing fabrics, or between the switching seams. It is often used for the outer periphery, neckline, and hem of heels and cuffs. In addition, piping that is made to stand out by putting it in a folded tape with a yarn or cord as a core is also widely used in clothes.

  When performing piping, it is easy to sew a bi-folded bias tape between two fabrics because it can be sewn by a main sewing machine.

  However, putting a yarn or a cord as a core to round the piping requires skill, and it is difficult to sew unless the sewing machine is also a special sewing machine. That is, when sewing clothes, it is extremely difficult to sew while performing piping in a state where the core is put in a folded tape, using only an industrial lockstitch sewing machine. For example, instead of a normal presser foot in a sewing machine, a piping tape presser as disclosed in Patent Document 1 (Japanese Utility Model Publication No. 4-32669) is used, or Patent Document 2 (Japanese Utility Model Publication No. 63-49267). ) And Patent Document 3 (Japanese Utility Model Publication No. 7-29975), a sewing machine having a piping tape guide device must be used.

  Further, Patent Document 4 (Utility Model Registration No. 3117795) proposes that a woven fabric having a shape-retaining property is folded in half and used as a piping tape instead of a bias tape. The piping tape disclosed in this publication is a narrow woven fabric using a fibrous shape retaining material for a part of warp and weft. When this tape is folded in two parallel to the longitudinal direction, the shape is retained in two by the shape-retaining material. Therefore, it is disclosed that the cuffs are prevented from being deformed.

For those using shape-retaining materials for clothing, in Patent Document 5 (Patent No. 3784398), a bag is formed along the periphery of the garment, cuffs, etc., and a deformable wire is formed in the bag. It is proposed to be inserted. It is disclosed that the shape of clothes such as a garment is changed by a wire inserted into a bag.

  As described above, it is difficult to attach a piping tape having a cored roundness while sewing clothes.

  As disclosed in Patent Document 4, in a narrow woven fabric using a shape-retaining material for warp and weft, the shape-retaining material is dyed differently from other yarns in dyeing. There is a problem of becoming. In addition, a lot is large in the case of a woven fabric, that is, when a single tape is woven, the minimum amount is several tens of meters. Furthermore, piping tapes of various shades are required from the viewpoint of the color and design of the fabric used for clothes. However, if different color tapes are prepared with narrow fabric as in Patent Document 4, There is a problem that it becomes a large lot.

  As disclosed in Patent Document 5, it is very troublesome to produce a garment by providing a bag around the periphery of the bag or cuff and inserting a shape-retaining wire into the bag. Is a problem.

  The present invention is to solve such a conventional problem, and to provide a piping tape that can form a piping with roundness and can be sewn together with a cloth such as clothes by a main sewing machine. Objective. It is another object of the present invention to provide a piping tape that can be produced in a small lot. It is another object of the present invention to provide a piping tape having a shape retaining property capable of changing the shape of a sewn portion.

  According to the present invention, a piping tape comprising a narrow tape and a plastic deformable plastic wire, the wire corresponding to the wire and the wire along one side edge of the narrow tape. The narrow tape is sewn by edge stitching with looper thread and needle thread so that the side edge of the narrow tape is not visible from the outside, and no wire is sewn on the other side edge of the narrow tape The above object is achieved by a piping tape characterized in that the fluctuation of the width of the piping tape is 15% or less.

  In order to prevent the wire from being seen from the outside, it is preferable that the number of stitches per 1 cm of the needle thread is 17 to 20 needles although it depends on the thickness of the looper thread. In particular, it is preferable that there are two looper yarns, and at least one of them is a crimped yarn.

  Further, it is preferable that the narrow tape is a biased fabric or a lace fabric.

  According to the present invention, a wire rod is sewn to one side edge of a narrow tape by stitching, and the wire rod and sewing thread (looper thread and needle thread) or a wire rod and a narrow tape corresponding to the wire rod Piping tape with a rounded part of the piping formed by the side edges and sewing thread. By sandwiching the piping tape between two pieces of fabric and sewing the piping tape together with the two pieces of fabric Piping with roundness can be formed. In this case, it is possible to easily sew with a sewing machine that is usually owned by a sewing factory. That is, the sewing operation does not require skill and does not require the use of a special sewing machine or instrument.

  According to the present invention, the piping rounded part is a state in which the wire and the corresponding narrow tape part are completely covered with the sewing thread of the sewing machine, so the piping part can be changed by changing the sewing thread of the sewing machine. It is easy to add changes such as color. Therefore, according to the present invention, various piping tapes can be prepared in a small lot.

  The piping tape of the present invention has a single narrow tape and is not folded in half like a conventional piping tape, so it is easy to sew even when it is sandwiched between two fabrics. The attached part does not become thick. Therefore, the piping tape of the present invention can be applied not only to the edge of a heel or the like but also to a switching portion, and can be applied to a fabric to be sewn, whether thin or thick.

  Since the tape for piping of the present invention has a substantially uniform width, it can be easily sewn and can be finished beautifully when it is sewn on clothes.

  According to the piping tape of the present invention, it is easy to attach anywhere, and since the wire contained in the core is made of a plastically deformable material, the shape of the attached portion can be variously changed. . For example, when the piping tape of the present invention is used for fringing the heel, it is possible to change its shape in various ways, such as standing the heel, laying it down, or waving it.

  In the present invention, since the number of stitches of the needle thread is 17 to 20 needles per 1 cm, the core wire and the corresponding narrow tape portion can be completely covered so as not to be seen from the outside, Narrow tape does not wave like a frill.

  In the mellow finish used to clean the ends of conventional knitwear, etc., the edges of the mellow are waved in a frilled state in order to hang the mellow lock while stretching the fabric. Since the sewing machine is applied with 17 to 20 stitches per cm so that the narrow tape is not stretched when sewing, the narrow tape is not substantially wavy.

  In the present invention, since the narrow tape is single, it is easy to sew anywhere, but when the narrow tape is made of biased fabric or lace fabric, the narrow tape can be slightly expanded and contracted to form piping. Even if the place to be done is not linear but curved, it is easier to sew.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing a piping tape of the present invention. FIG. 2 is a schematic enlarged cross-sectional perspective view for explaining a portion where the wire is sewn to the side edge of the narrow tape. FIG. 3 is a schematic explanatory view showing various aspects of the positional relationship before sewing the narrow tape and the wire.

  The piping tape 1 of the present invention is composed of a narrow tape 2 and a wire 3. The narrow tape 2 may be a bias tape, a tape woven by a narrow loom, a lace fabric cut into a narrow width, or a lace knitted into a narrow width. The narrow width in the present invention is 15 mm or less, preferably 6 mm to 12 mm. This is because if the width is too large, the thickened portion (sewing allowance) becomes wide when stitched with the fabric constituting the clothes as a piping tape.

  The wire 3 is made of a plastic material that can be plastically deformed, and preferably has a diameter of 0.4 mm to 1.3 mm. When the wire is too thin, it is deformed even if a slight force is applied, and the shape retainability deteriorates. If it is too thick, it is difficult to sew on the edge of the narrow tape, and it is difficult to deform. Therefore, when sewing as piping tape 1 on clothes etc., it is difficult to sew on curved portions. Because it occurs.

  Known linear plastic materials that can be plastically deformed include polyolefin-based plastic (for example, high-density polyethylene) wires. For example, what is marketed by Mitsui Chemicals as "Techno Roto" (registered trademark) can be used as the wire 3 of the piping tape 1 of the present invention.

  The wire 3 as described above is sewn to only one side edge of the narrow tape 2 using an overlock sewing machine. In this case, the sewing machine thread prevents the wire 3 or the wire 3 and the corresponding side edge 2a (see FIG. 3) of the narrow tape from being visible from the outside.

  In FIG. 2, the wire rod 3 is sewn to the side edge of the narrow tape 2 by a normal edge stitching with the needle thread 4, the upper looper thread 5, and the lower looper thread 6 by an overlock sewing machine of three single threads. The state is shown schematically. In FIG. 2, for the sake of explanation, the wire is drawn so that the wire can be seen between the yarns. However, in the actual piping tape of the present invention, the wire 3 and the side edge 2a of the narrow tape are hidden in the sewing thread. I can't see it. For this reason, in the present invention, the number of stitches of the needle thread 1 is larger than that of normal edge stitching, and the looper threads 5 and 6 are sewn tightly. That is, in the case of normal edge stitching with an overlock sewing machine, it is 18 stitches / 3 cm (thin fabric) to 12 stitches / 3 cm (thick fabric). In the present invention, the number of stitches of the needle thread is 17 to 20 stitches per cm. Particularly preferred are 18 to 19 needles.

  In the edge stitching shown in FIG. 2, the tensions of the upper looper thread 5 and the lower looper thread 6 are adjusted in the same manner so that they meet at the center. Instead of the edge stitching, it may be a winding sewing in which the lower thread tension is increased and the upper looper thread is pulled back.

  In addition, mellow lock (mellow finish) has been conventionally performed at the end of cuffs and hems of knit clothing, etc. In mellow lock, since the fabric is stretched and stitched finely, the finished product is wavy and frilled It has become. However, in the present invention, the wire rod 3 is sewn in such a manner that the piping tape 1 does not wavy in such a frill shape even by adjusting the traveling speed of the piping tape 1 to make fine stitches.

  The sewing thread used in the present invention is not particularly limited, but a crimped thread such as woolly nylon is preferably used as the looper thread. A crimped thread is bulky and is suitable for covering the surface of the sewn part.

  FIG. 3 shows the positional relationship between the wire 3 and the narrow tape 2 before sewing. FIG. 3A shows a case where the width of the narrow tape is narrow, for example, about 6 mm. The wire 3 is in contact with the end of 2. FIG. 3B shows a case where the width of the narrow tape is narrow, for example, about 8 mm, and the wire 3 is placed on the side edge 2 a corresponding to the wire 3 of the narrow tape 2. FIG. 3 (c) shows that the side edge of the narrow tape is guided in a state where the wire 3 is partially wound. FIG. 3D shows a case where the width of the tape is relatively large, for example, about 12 mm, and the side edge 2a of the tape 2 is guided to the sewing location of the sewing machine so that the wire 3 is completely wound. Which indicates that.

  FIG. 4 shows an example of an overlock sewing machine. In the illustrated sewing machine, a member different from a normal overlock sewing machine is attached to manufacture the piping tape of the present invention. That is, a tape / wire guide 13 is provided on the near side where the needle 11 of the overlock sewing machine falls. FIG. 5 is a cross-sectional view showing an example of the tape / wire guide 13. As shown in FIG. 5, the tape / wire guide 13 has a tape guide portion 13 a and a wire guide portion 13 b. FIG. 6 is a perspective view of an example of the presser foot 12 for manufacturing the piping tape of the present invention (note that the presser support member is omitted in FIG. 4). Unlike the ordinary presser foot of the lock sewing machine, the presser foot 12 is provided with a tape / wire guide 12a wound downward and a recess 12b at the needle drop position. The narrow tape 2 and the wire 3 are guided by the tape / wire guide 12a of the presser foot 12, and the needle 11 and the upper and lower loopers (not shown) are formed in the recess 12b in the positional relationship as shown in FIGS. 3 (a) to 3 (d). ) 4, 5 and 6, the wire 3 is sewn to the side edge of the narrow tape 2.

  Further, a take-up roller comprising two rollers 14 and 15 is provided on the rear side of the sewing machine, and the piping tape 1 sewn by the take-up rollers 14 and 15 is positively taken up at a constant speed. Further, a feeding roller may be provided on the near side, and the tape 2 or the wire 3 may be fed out so as to be in contact therewith.

  In the present invention, the width of the completed piping tape 1 is substantially uniform, that is, the variation of the width is 15% or less. The narrow tape 2 and the wire 3 are regulated so as not to be laterally displaced by the tape / wire guide 13 and the take-up rollers 14 and 15 are used to take up at a constant tension and speed. It is possible to eliminate almost no fluctuation in the width of the. And, since the take-up rollers 14 and 15 are taken up at a constant tension and speed, the piping tape 1 can be prevented from undulating like a frill.

  The conventional normal overlock sewing machine does not have such a tape / wire guide and take-up roller. When the inventor tried to sew a wire rod on a narrow tape using such a conventional sewing machine, the width of the completed piping tape varied greatly, and it varied by nearly 50%. Further, when the sewn piping tape was sewn while being pressed (pulled) by hand, the moving speed of the piping tape changed, so that the completed piping tape was wavy.

It is a front view which shows the tape for piping of this invention. It is a typical expanded cross-sectional perspective view for demonstrating the location which sewn the wire to the side edge of the narrow tape. It is typical explanatory drawing which shows the various aspects of the positional relationship before sewing a narrow tape and a wire. It is a perspective view of an example of the overlock sewing machine for manufacturing the tape for piping of this invention. It is sectional drawing of an example of the tape and wire guide in the sewing machine shown in FIG. It is a perspective view of an example of the cloth presser in the sewing machine shown in FIG.
