る。2. Description of the Related Art Conventionally, as a sewing thread, cotton,
Sewing threads such as silk and synthetic fibers are widely used,
In recent years, synthetic fiber sewing threads have been widely used from the viewpoints of strength and dyeing fastness. Especially, among synthetic fiber sewing threads, polyester filament sewing threads and polyester spun sewing threads have become the mainstream.

る。Polyester filament sewing threads are excellent in strength, but inferior in heat resistance and abrasion resistance.
There is a problem that the high-speed sewability is poor. On the other hand, the polyester spun sewing thread has excellent high-speed sewability because its fluff improves heat resistance and wear resistance, but it is inferior in strength, and the fluff comes off during sewing and There is a drawback that it adheres to the hook portion and the pressing portion of the sewing machine and contaminates the sewing cloth.

ている。[0004] As a sewing thread which improves the defects of these polyester filament sewing thread and polyester spun sewing thread, for example, Japanese Patent Publication No. 62-38457 discloses a polyester filament as a core component and a polyester short fiber as a sheath component. A core yarn sewing thread has been proposed.

糸がしごかれて、撚りが解撚され、ミシン糸の単糸割
れ、糸切れ、目とびなどが生じ、可縫性が低下するとい
う問題がある。Although this sewing thread is excellent in strength and high-speed sewability, since it is a twisted sewing thread, it is sewn with a sewing machine needle or a sewing machine hook during back stitching, zigzag stitching and the like. There is a problem that the twist is untwisted and the sewing machine yarn is broken into single yarns, broken, and skipped, and the sewability is deteriorated.

縫製トラブルの原因となるという欠点がある。In order to solve this problem, the sewing thread is coated or impregnated with an adhesive resin to prevent untwisting of the sewing thread. In this sewing thread, the adhesive resin is coated. In addition, the manufacturing cost is high because it requires a special device for impregnation and an extra step. Moreover, at the time of sewing, the sewing machine thread is squeezed by the sewing machine needle or the sewing machine hook, and the resin falls off, and the sewing machine There is a drawback that it adheres to the hook and the like and causes various sewing problems.

提案されている。For the purpose of improving the drawbacks of the conventional twisted sewing thread, for example, JP-A-2-2694 is used.
Japanese Unexamined Patent Publication No. 4 (1994) proposes a sewing thread composed of a polyester filament or a polyester spun yarn and a low-melting thermoadhesive polyester multifilament, in which the thermoadhesive polyester filament is melt-bonded to fix the twist.
【０００８】このミシン糸では、確かに耐解撚性の向上

ったものとなる。Although the untwisting resistance is certainly improved in this sewing thread, its effect is not sufficient because the heat-adhesive fibers are filaments, and the twisting is still performed during back stitching, zigzag stitching and the like. Is untwisted and the single thread of the sewing thread breaks,
When the polyester spun yarn is used, fluff is relatively frequently dropped off, and when the polyester filament is used, the high-speed sewability becomes inferior.

を防止することはできない。Further, JP-A-62-162039 comprises a blended yarn containing a low-melting point copolyester short fiber, which is melted or softened to increase rigidity. , A sewing thread that prevents the occurrence of skipped stitches is described, but since this sewing thread is composed only of spun yarn, it has low strength and is also used for back stitching and zigzag stitching. Untwisting that occurs cannot be prevented.

A thermoadhesive spun yarn containing 20 to 100% by weight of thermoadhesive short fibers which are composite fibers is used. Melting point of sheath component is 10
When the temperature is lower than 0 ° C, the heat-adhesive short fibers are melted by a sewing machine needle heated by frictional heat during sewing, causing sewing trouble, and further, the heat-adhesive short fibers are melted at the time of dyeing. And the effect of the present invention is not achieved. On the other hand, when the melting point exceeds 180 ° C., high temperature is required for heat bonding, which is not preferable in terms of heat deterioration of fibers and processing cost. A more preferable range of the melting point of the sheath component is 130 to
It is 160 ° C.
