Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a tape for attaching eyelets, etc. of underwear, etc., which is sewn to the foundation of body suits, waist knitwear, etc., and underwear, etc. It is something.

(Prior art) Foundations such as bodysuits and waist knitwear are generally worn to create a beautiful figure by correcting physical defects, and are hygienic and easy to blend into the skin. In addition to requiring the use of stretchable materials, it is also required to have functionality such as improved correction effects, convenience in wearing, and easy partial opening after wearing.

For example, as shown in FIG. 4, a part of a bodysuit B, the crotch area C where the buttocks fabric and the lower abdomen fabric are connected is divided, and each end edge D has a female
By attaching a male hook, etc., and making it possible to open and close this part, it is possible to conveniently use the toilet after wearing the bodysuit. In waist knitpers that are worn while wearing clothes to correct the body shape of the torso, instead of connecting both ends of the belt with a fastener, etc., eyelets are attached along both ends, and the belt is passed through the eyelets. There are devices that improve the body shape correction effect by adjusting the tightness of the straps.

In such products, even if the hooks and grommets are attached directly to the stretchable fabric, they will come off immediately, so a long non-stretch tape with a core material inside and fixed along the longitudinal direction is used. Cut to length, attach hooks and eyelets to the sewn mounting tape to prevent the edges of the cut portion from fraying, and sew this mounting tape in place on the body suit, etc. It is used like this.

(Problem to be solved by the invention) However, the seam allowance at the cut edge of the mounting tape, which is obtained by cutting a long tape into a predetermined length, is narrow in the width direction of the long tape, and it is difficult to prevent fraying. Since the sewing is done at a predetermined pitch, it becomes difficult to completely sew all the way to the edges, which causes the seam allowance to fray from the edges, and one side of each of the many mounting tapes. The problem was that it took a lot of time to manufacture because the cut edges of the first one had to be aligned and sewn together by hand, and then the other cut edges had to be sewn together.

Furthermore, even when sewn onto a body suit, etc., there was a drawback that the mounting tape frayed early from the edge along the cutting line, making it easy for the mounting tape to separate from the body suit, etc.

In view of these drawbacks of conventional mounting tapes, it is an object of the present invention to provide a tape for mounting eyelets, etc. of underwear, etc., which can reliably prevent fraying from the cut edge and has excellent manufacturability.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a core sheet made of thermoplastic fibers, in which fabrics using thermoplastic fiber threads are polymerized on both sides, and the edges in the longitudinal direction are polymerized. The gist is a tape for attaching eyelets, etc. of underwear, etc., which is characterized in that a long tape on which is sewn is cut to an appropriate length by ultrasonic or high-frequency welding means, and the cut edges are welded. .

(Example) Next, an example of the tape for attaching eyelets, etc. of underwear, etc. of the present invention will be described below based on the drawings.

FIG. 1 is a plan view of a tape for attaching eyelets, etc. for underwear, etc. according to a preferred embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the - line of FIG. Polymerize fabrics 2 and 3 woven using nylon fiber threads on both sides of 1,
In addition, a long tape T whose longitudinal edges are stapled and sewn 6 is melt-cut 4 to an appropriate length L using ultrasonic or high-frequency welding means, and the melt-cut edges 5 are welded. There is.

The surface of the welded fusing edge 5 may be a smooth surface, but if the entire fusing edge 5 is welded, that part will be hardened by heating and the whole will become hard, as shown in A, B, and C of Fig. 5. It is preferable to have a dot-like, streak-like, or mesh-like shape.

The tape for attaching eyelets, etc. of underwear, etc., configured in this way is used after attaching the hooks, eyelets, etc.
As an example shown in the figure, it is used by being sewn onto the edge D of the divided crotch part C of a body suit B.

In addition, in this example, the core material sheet 1, the fabric 2,
Although nylon is used as No. 3, materials such as polypropylene, polyethylene, etc. that can be welded by ultrasonic wave or high-frequency welding can be used.

In addition, the tape for attaching eyelets, etc. of underwear, etc. in the above embodiment is designed to attach hooks, eyelets, etc. later, but as shown in Fig. 3, fasteners F such as hooks, eyelets, etc. are attached in advance. In some cases, the integrated long tape T is cut by fusing 4 to an appropriate length L, and the cut edges 5 are welded.

Furthermore, although the materials of the hooks and eyelets are not particularly specified, they may be made of metal or synthetic resin.

(Operation and effect of the invention) The tape for attaching eyelets etc. of underwear etc. according to the invention explained above has a core sheet made of thermoplastic fibers, fabric using thermoplastic fiber threads polymerized on both sides, and longitudinal edges. Since the long tape with the sections sewn is melt-cut to an appropriate length by ultrasonic or high-frequency welding means and the melted edges are simultaneously welded, when the long tape is cut to a predetermined length, At the same time, the fused edges are welded and bonded over the entire width, and fraying from the fused edges is completely eliminated. This eliminates the need to sew the seam allowances of the cut edges to prevent cumbersome fraying, which was required in the past in addition to cutting the long tape, and makes it possible to use tape for attaching eyelets, etc., to underwear, etc. It can be provided at low cost.

In addition, when sewing the seam allowance of the cut edge to prevent fraying as in the past, due to the narrow width of the cut edge and the sewing pitch, it is best to sew the cut edge completely to the end. This is difficult and may cause fraying from the edges of the seam allowance, but in the present invention, the welded edges are welded over the entire width to the edges, so
The fraying from the edges is also completely eliminated.

Furthermore, the tape for attaching eyelets, etc. for underwear, etc. of the present invention can be sewn to objects such as bodysuits using the welded edges, so its attachment strength is high and unlike conventional This also eliminates the drawback that the mounting tape tends to come off easily from the part that is sewn onto the body suit or the like.
