DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the fabric of the present invention is applied to a blouse having a pattern on a collar will be described below with reference to FIGS. First, in FIGS. 1 and 2, a cloth material 1 is formed of natural fibers such as cotton for both warp and weft, and a cloth 2 made of a heat-meltable fiber such as a chemical fiber is laid on top and bottom of this. The blouse 3 is formed by fusing the cloth material 1 and the cloth 2 along the cutting part 4 at the collar, and a concave pattern part 5 or a hole-shaped pattern hole part 6 is formed at the periphery of the cutting part 4. ing.

Next, a procedure for manufacturing the blouse 3 will be described. First, a cloth 2 made of hot-melt fiber is overlaid on top and bottom of a cloth material 1. In this case, if the edge of the cloth 2 is temporarily fixed to the cloth material 1, the subsequent work can be performed efficiently. The cutting section 4 and the pattern sections 5 and 6 are fused and welded by the "sheet material ultrasonic processing apparatus 20" proposed by the present inventor in an earlier application (Japanese Patent Publication No. 3-42344).

In FIGS. 3 and 4, a plate-shaped mold 21
Is a fusing blade 22 having a sharp cutting edge provided for forming the cutting portion 4 and the pattern hole portion 6, and a welding blade 2 having a flat cutting edge provided for forming the concave pattern portion 5.
And 3. The cloth material 1 and the cloth 2 to be processed are placed on the mold member 21, and an ultrasonic horn 24 is provided from above the cloth material 1 and the cloth 2 so as to contact the cloth material 1 and the cloth 2. By moving the mold member 21 and the cloth material 1 and the cloth 2 while cutting, the cutting section 4 and the hole-shaped pattern hole 6 are melted by the fusing blade 22, and the melted cloth 2 penetrates into the cut to prevent fraying. do. At the same time, if the concave pattern portion 5 is formed by the welding blade 23, the blouse 3 having a pattern on the collar is manufactured.

Here, the cutting and fraying of the cut portion 4 and the pattern hole 6 and the formation of the concave pattern portion 5 are carried out by increasing the local temperature by ultrasonic vibration and melting the fabric 2 to prevent fraying. , And the cloth material 1 is blown off by the pressing force of the fusing blade 22. That is, the natural fiber portion of the cloth material 1 is cut by the cutting blade having a sharp cutting edge, and the heat-meltable fiber of the cloth 2 is heat-melted by ultrasonic vibration. Therefore, the cuts of the cut portion 4 and the pattern hole 6 are securely prevented from fraying.

The above-mentioned "sheet material ultrasonic processing apparatus 20"
In addition, the “border decoration processing device 30” described later can easily change the melting temperature by changing the frequency applied to the ultrasonic horns 24 and 34, so that the optimum is determined according to the material of the workpiece. A melting temperature can be obtained. Also,
By making the cross-sectional shape of the fusing blade 22 sharp and increasing the pressure contact force (pressure per unit area) of the fusing blade 22 against the cloth material 1, fusing can be facilitated. Therefore, the workpiece is not excessively melted or scorched as compared with fusing and welding by a heating blade or the like.

According to the first embodiment, the melted cloth 2 penetrates into the cut at the same time as the cutting of the cutting section 4 and the cut is completely frayed, so that the fray is reliably prevented from fraying. The cutting edge is not bulky, the usability is improved, and the decorativeness of the cutting edge can be enhanced by changing the shape of the fusing blade into a scalar shape or a lace shape. In addition, since cotton is used for the warp and the weft, water absorption can be ensured, and this is effective for fabrics that are frequently washed, such as underwear such as blouses.

FIGS. 5 and 6 show a second embodiment in which the present invention is applied to a pattern portion of a garment. A tape 7 made of a heat-meltable fiber, for example, a chemical fiber, is laminated on and under a cloth material 1. Here, the pattern portion 5 and the pattern hole portion 6 are formed. The pattern portion 5 and the pattern hole portions 6 and 8 are fused and welded by the "border processing device 30" proposed by the present inventor in an earlier application (Japanese Patent Application Laid-Open No. 2-61171). That is, in FIG. 6, the fusing blades 32 and 35 (the cross-sectional shape is shown in FIG. 7) having a sharp cutting edge corresponding to the pattern hole 6 and the welding blade 33 having a flat cutting edge provided in the vicinity thereof. The work material 31 serving as a workpiece is sandwiched between the processing roll 31 provided with the ultrasonic horn 34 and the ultrasonic horn 34.
Is rotated to melt the pattern hole 6 and prevent it from fraying with the melted tape 7 to form the concave pattern 5.

FIG. 8 shows a third embodiment in which the present invention is applied to a collar portion using an interlining.
Between the cloth material 1 and the interlining 9.
Are repeated. When the cloth material 1, the interlining 9 and the cloth 2 are subjected to ultrasonic processing in the same manner as described above, even when the thick interlining 9 is used, the cloth material 1 and the interlining 9 are melted and three cloths are used. 2 can penetrate the cut to ensure fraying. These second and third embodiments also have the same effects as the first embodiment.

The present invention is not limited to the embodiment described above and shown in the drawings. The cloth may be provided not only on both sides but also on at least one side.
May be appropriately selected according to design requirements.
Various modifications are possible without departing from the gist, such as application to all cloth products such as clothing products such as blouses, underwear, place mats, coasters and handkerchiefs.
