JPS598574Y2 - upper material of footwear - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an upper material for footwear that is machine embroidered.

The upper material of footwear such as sandal bands is very fashionable,
Various materials are used and various designs are applied, but in recent years, one with machine embroidery is often used.

Incidentally, although the embroidered upper material looks beautiful, once the embroidery thread breaks due to friction or the like during use, there is a problem in that the embroidery thread frays in a chain reaction.

Therefore, conventional methods have generally been adopted to reinforce the back of the upper material, which is likely to cause friction with the foot, by applying a cloth to the back of the upper material.

However, for example, in sandal bands, etc., especially for summer wear, the design requires that the bare foot be seen through the upper material, and products using the above-mentioned cloth do not meet this requirement. I can't be satisfied.

This invention was devised in view of the above-mentioned problems with conventional uppers with embroidery. By heat-treating the embroidery thread to melt the heat-adhesive thread of the bobbin thread, and bonding the heat-adhesive thread to the upper thread and upper material, even if the embroidery thread breaks, it will not fray in a chain reaction, and the fabric It is something that has made it unnecessary.

Hereinafter, the present invention will be specifically described with reference to an embodiment of the illustrated sandal band.

The sandal band 1 of the sandal shown in FIG. 1 has the structure shown in FIG. 2.

In FIG. 2, 2 is an upper material such as cloth, 3 is an upper thread made of ordinary thread, and 4 is a heat-adhesive thread (for example, the product name Elder manufactured by Toray Industries, Inc. has a melting temperature of about 90° C.).

As is well known, the upper thread 3 and the lower thread 4 are entangled with each other,
Upper thread 3 is sewn onto upper 2 to form the desired design.

The upper material having the above structure is heat-treated at a temperature that melts the lower thread of the heat-adhesive thread.

However, this heat treatment must not completely dissolve the lower thread 4 of the heat-adhesive thread, and it is necessary to maintain its original shape as a thread. Weld it to the material 2 and needle thread 4.

Therefore, according to this embroidery, since the bobbin thread 4 is adhered to the back side of the upper material, it not only has excellent abrasion resistance, but also
Even if part of the upper thread is cut, the upper thread will not become frayed in a chain reaction.

As is clear from the above description, the embroidered upper material according to the present invention has a simple structure in which the lower thread is embroidered using heat-adhesive thread and the upper material is heat-treated. Since it can be bonded to the upper thread, even if the embroidery is cut, it will not become unraveled in a chain, and therefore the cloth etc. will not be needed and the desired purpose can be achieved.
