を可能としたものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven and knitted fabric which constitutes various fiber products such as bags, and has a strong bonding strength by a heat welding method without sewing two or more pieces of the woven and knitted fabric. It made knitting possible.

As for the method of joining woven and knitted thermoplastic thermoplastic fibers, sewing machine sewing is almost the same as before, and only thin woven and knitted fabrics that do not require strong joining strength are used.
The method of joining by a heat fusion method is taken. As you know, it is difficult to mass-produce using a sewing machine, and the heat-fusing method does not provide sufficient joint strength.
A woven or knitted fabric having a basis weight of at least 40 g / m 2 per square rice has not been put into practical use because it does not exhibit the sealing strength. INDUSTRIAL APPLICABILITY The present invention is a woven or knitted fabric that can be completely joined by a heat bonding method regardless of whether the woven or knitted fabric has a basis weight.

を提供せんとするものである。SUMMARY OF THE INVENTION In the present invention, when a woven or knitted product is joined by heat welding without the need for sewing, the problem is the joining strength of the part where the woven and knitted product is joined. The thermal bonding of the woven or knitted material is the bonding of the dots while the film or the like is the bonding of the surfaces. Therefore, under the same conditions, the woven and knitted fabric is weak due to the difference in the bonding area between the woven and knitted fabric and the film. Therefore, the woven and knitted fabrics must have a large sealing area as compared with the heat-bonding of a film or the like. That is, the width of the heat-bonding seal bar must be widened. The thermoplastic synthetic fibers are fused while heat shrinking as the temperature rises. Therefore,
If you raise the temperature of the seal bar to a temperature above heat welding,
When the seal bar comes into contact with the woven or knitted fabric, it simultaneously contracts,
Stable woven and knitted products cannot be joined. The present invention provides a woven or knitted fabric that can be obtained by a heat bonding method without shrinking the sufficient bonding strength required for producing a fiber product.

し収縮するのを防ぐための温度差である。The operation of the woven or knitted fabric of the present invention will be described. Since the yarns having different melting points are woven into the structure of the woven or knitted fabric, the temperature at the bonding point is higher than that of the lower melting point and that of the higher melting point If heated and pressed at a temperature lower than the above, the lower melting point yarn melts and acts as an adhesive, and the higher melting point yarn shrinks from softening of the lower melting point yarn until reaching melting. And protects the dimensional stability of the bonded area. The melting point difference of 20 ° C. or more is a temperature difference for preventing the softening and shrinking of the high melting point yarn when the woven or knitted fabric is heated and pressed at the low melting point temperature.

FIG. 1 is a partial plan view showing the structure of the woven or knitted fabric of the present invention. The woven or knitted fabric A of the present invention is formed by weaving threads having different melting points into the structure. As one example thereof, polyester (melting point 250 ° C.) 50 denier 24 filament is used as warp 1, and 50 denier 24 filament +75
Denier 24 filament polypropylene (melting point 16
(0 ° C.) is woven as the weft yarn 2. And 1 at the adhesion point
When heated and pressurized at a temperature of 60 ° C or higher and 250 ° C or lower,
Only the polyester yarn is in its original state, and the polypropylene yarn acts as an adhesive. As in the embodiment, the warp 1 and the weft 2 and the weft 2 ′ having a lower melting point than the warp 1 and the weft 2 can be used, but either the warp 1 or the weft 2 has a different melting point. It may consist of material.
