Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape and a cloth for preventing fraying, and more particularly, to a tape or a cloth which is not frayed even when its side edges are cut during sewing or after sewing with another cloth. It relates to tape and fabric for prevention.

[0002]

2. Description of the Related Art Conventionally, a tape composed of a warp and a weft (a woven tape and a knitting tape of a weft insertion type) has a warp at both side edges. Usually, the end of the weft holds the warp so that the end of the weft is not frayed, and has the same effect as the end of the weft. However, when using the tape sandwiched between other fabrics, the tape is cut and removed with an overlock sewing machine together with the other fabric, or after sewing, the excess fabric is cut and removed. In some cases, the side edges of the tape may be cut. Then, the end of the weft holding the warp so that it does not fray at the end is also cut and removed,
The warp thread is pulled out in the weft direction, and the tape side edge is frayed.

[0003] The above conventional case is illustrated with reference to the drawings.
A tape t as shown in FIG. 7 is sandwiched between the fabrics S, S as shown in FIG. 8, and one needle g or two needles g are cut while removing excess fabric at a cutting position h by a cutter when sewing with an overlock sewing machine. The sewing is performed with the needles g and i, but if the cutting position is shifted to the inside h ', a part of the tape t, particularly the side edge f of the tape is cut, and the warp is held so that the warp does not come off and fray. The end of the weft is also cut, and the holding force of the warp is lost. As described above, there is a problem that the warp escapes in the weft direction and the fraying phenomenon successively spreads to the inside of the tape.

[0004] In order to prevent such spread of fraying in the tape, a low-temperature welding yarn (for example, an elder yarn ... trademark) is inserted into the structure of the tape, and the warp and the weft are melted by post-processing by heating. Even if the tape is cut by welding, the warp is prevented from coming off, and fraying can be eliminated. However, the use of low-temperature welded yarns has the following disadvantages.

[0005] The low-temperature welded yarn turns yellow and affects the color of the product. Sublimation of dye fastness deteriorates by raising the temperature for melting in post-processing (generation of color fading phenomenon). Since the dye fastness is poorly sublimated, the number of working steps for washing and drying and setting the product is increased, resulting in an increase in cost. The cost of the low-temperature welded yarn increases. The product hardens. This causes a similar problem not only in the above-described tape but also in the side edge of the cloth. Therefore, in the present invention, it is possible to provide a tape and a fabric that can prevent fraying by improving the configuration of the tape or the fabric itself without using the low-temperature welding yarn.

[0006]

In the tape for preventing fraying according to the present invention, as described in claim 1, at least one of the two side edges of the tape constituted by the warp and the weft yarns. Is characterized in that a weft is added to the inner position and the additional weft is held so that the warp does not fray. Claim 1
In the anti-fraying tape, the weft for preventing the warp from fraying is added at least inside the one side edge, so that even if the side edge of the tape is cut, it will become frayed. There is no.

[0007] More specifically, when the tape is sandwiched between other fabrics and then sewn or after sewing, the excess fabric is cut and removed. At this time, the cut portion shifts inward and the side edge of the tape is also cut. Would. Then, the end of the weft holding the warp so as not to be frayed is also cut, the warp is pulled out in the weft direction and the tape side edge is frayed, and the fray spreads inward, but the position of the additional weft is Can stop the spread of fraying, and prevent further fraying.

More specifically, according to the present invention, the inner position where the weft yarn is added is within the range where the tape is cut and removed at the time of sewing with another cloth or after sewing. It is characterized by being located at the position of the other sewing range, so that the above-mentioned fraying prevention effect can be realized properly. Regarding the structure of the tape according to the present invention, the warp, the weft and the additional weft can be prevented from being frayed regardless of whether the warp, the weft and the additional weft have a single structure as in claim 3 or a double structure as in claim 4. Tape can be configured.

[0009] The additional weft for preventing fraying may be provided not only at one position inside the one side edge of the tape but also at two positions inside the both side edges. . Claims 5 to 8 relate to a structure in which a cloth is used instead of a tape.

[0010]

Next, an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing an essential part of an example of a tape T. The tape T is composed of a warp 1 and a weft 2, and c in the figure is a normal warp 1 and a weft. 2 shows a sewing range in which a weft 20 for preventing fraying is added in addition to 2, and the weft 20 is added to at least an inner position of one of the illustrated side edges f among both side edges, "e" indicates an end of the additional weft 20, which is a fray preventing portion which holds the warp 1 so as not to be frayed. D in the figure
Is a removal allowable range in which the tape T may be cut and removed at the time of sewing or after sewing with another cloth, and the position where the weft 20 of the sewing range c is added is located inward of the removal allowable range d. Will be located.

FIG. 1 shows a single woven structure in the case of a woven tape, while FIG. 2 shows a case of a double woven structure in the sewing range c. Constitutes a fray prevention part e by the added weft yarn 20 as in the case of the single weave. Next, FIG. 3 is a schematic cross-sectional view showing a state in which the tape T according to the present invention is sewn while being sandwiched between other fabrics S, S. FIG. The state after cutting at h is shown in a schematic sectional view.

More specifically, referring to FIGS. 3 and 4, the tape T is sandwiched between the fabrics S, and sewn with one needle g or two needles g, i using an overlock sewing machine. At the cutting position h by the cutter at the time of sewing or after the sewing, along with the excess cloth d.
It also cuts and removes the tape part in the normal weft 2
End portion f is cut and removed. Therefore, even if a warp may fall out in the remaining cutting allowable range d ', the spread of the fray is prevented by the fray prevention portion e by the end portion of the added weft yarn 20. Will be prevented.

The stitch type of the sewing by the overlock sewing machine is surging (discarding) with one needle and two threads.
Known stitches such as stitches with three single-needle threads and stitches with two-needle four-thread threads are used. Further, FIG. 5 shows a case in which a fray preventing portion by the end e of the weft 20 added to the tape T having the pipe-shaped hollow portion P formed at one end is formed, and FIG. Although the state in which the ripple is blocked at the end e is shown for convenience, the allowable range of cutting of the tape T outside the weft preventing portion due to the end e of the additional weft 20 remains too long for sewing use. It is preferred that sewing and cutting be performed so that there is no stitching.

The shape, width and length of the tape T are
It can be carried out arbitrarily according to the purpose of use, and it is also possible to carry out fray prevention portions by additional wefts on both sides inside each side edge of the tape width.
Although the above-described embodiment relates to a tape,
The same operation can be performed in the case of fabric instead of tape.

[0015]

As described above, according to the tape of the present invention,
By forming a part that becomes a fray prevention part by the addition of weft, the cutting position of the excess cloth is shifted even when sewing the tape by sandwiching it between other cloths, and cutting one end of the tape Even if the side edge is removed, the additional weft within the sewing area holds the warp so as not to be frayed, so that the warp can be reliably prevented from coming off in the weft direction and spreading the fray.

[0016] Accordingly, it is also possible to eliminate the need for great care in cutting excess cloth when sewing with a tape in between.
The efficiency of sewing using the tape is improved, and the productivity is improved. Further, since it is not necessary to use a low-temperature welded yarn as in the related art, the above-described drawbacks due to the use of the low-temperature welded yarn are also
Can all be resolved. Although the above effects have been described with respect to the tape, the same effects can be obtained when fabric is used instead of the tape.
