BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail.

In the composite flat integrated yarn according to the first aspect of the present invention, some or all of the plurality of yarns in the width direction are irregularly overlapped, and the yarns are partially or continuously formed. In addition to being integrated, the entire yarn has a flat shape.

Here, "a part or all of the plurality of yarns in the width direction are irregularly superposed" means that the superposed state in the width direction in the cross section of each constituent yarn is irregular. However, since the form of the yarn generally has a substantially circular cross section, it means that the yarns are overlapped in the diameter direction.

In the present invention, it is desirable that each yarn is arranged as parallel as possible to the length direction (substantially parallel). They may be superposed at an angle in a diagonal direction. In addition, the overlapping state of two or more yarns may have a multiplex structure of substantially double, triple, etc. in the width direction of each yarn, but at least a part of the overlapping state in the width direction of each yarn. Are preferably shifted and overlapped.

In the present invention, the fact that the yarns are partially or continuously integrated and that the whole yarn has a flat shape means that the width (diameter) direction of each constituent yarn and This indicates the integrated state of the contact surfaces of the yarns in the length direction. In particular, even if the yarn has a circular (circular) cross-section, it is finally flattened by pressing, so that the aggregate is formed. This means that the entire yarn is flattened, and has a structure of being bundled by integrating the contact surfaces. Expressing the degree of flattening by the ratio of the thickness and width of the bundled yarn,
In the present invention, the ratio between the thickness and the width of the bundled yarn is preferably 1: 2 or more, more preferably 1: 5 or more, and still more preferably 1: 1.
0 or more.

As a method of integrating the yarns in the present invention, techniques such as entanglement of the yarns with fluff or an interlace (vortex air jet), bonding by a glue material (adhesive), a solvent or heat fusion are used. In addition, as a method of simultaneously processing the integration and flattening of each yarn,
For example, it can be easily processed by feeding a plurality of superposed constituent yarns into a gap between two (one pair) rollers in a heated or heated atmosphere, and applying a temperature and an external pressure such as pressure bonding or pressing deformation. For this reason, the handleability of the composite flat integrated yarn of the present invention is greatly improved.

Therefore, in the present invention, the material, structure, form, hue, etc. of each constituent yarn are not restricted at all.
For example, natural fibers, regenerated fibers, synthetic fibers, or the like, or spun yarns, continuous multifilament yarns, slit yarns, and the like, or raw, processed, or mixed yarns thereof can be used alone, mixed, or combined. When integrating by heat fusion, it is preferable to mix thermoplastic synthetic fibers having a low melting point.

In the present invention, the number of the plurality of yarns is two or more, preferably two to ten, more preferably three to six.

The invention according to claim 2 is characterized in that some or all of the plurality of yarns have different dyeing properties or are colored in different colors. Here, a part or all of the constituent yarns have different dyeing properties or are colored in different colors, which means that the yarns are of the same type, different types, or a mixture thereof, in which post-dying expresses different dyeing properties. Furthermore, it means that the fiber is composed of fibers which are dyed, dyed or mixed with these or mixed with a post-dyed type. Therefore, the combination of colors as the multicolor flat integrated yarn of the present invention is simple and has a high degree of freedom.

The invention according to claim 3 is characterized in that part or all of the constituent yarns are made of thermoplastic synthetic fibers, and the yarns are partially or continuously thermally fused. I have.

In the present invention, the term "heat-fused" means that the bonding method is limited to the heat-sealing using a heating roller or the like by utilizing the thermoplasticity of the yarn. Using a roller made of the same type of unevenness or a combination of these as the gear shaping method known as a surface smoothing or crimping method, feeding and removing the superposed yarn between these pairs of rollers. By appropriately setting the yarn tension balance with the roller, the temperature of the roller, the number of rotations (speed), and the like, the contact surfaces of the yarns are thermally fused to be bundled.

In the present invention, the heat treatment temperature for heat fusion is preferably from the glass transition point temperature of the thermoplastic synthetic fiber to the melting point, and below this temperature, the pressure and time can be changed. In addition, it is preferable that the degree of fusion is maintained so that the yarn is bundled until a knitted fabric is manufactured using the yarn.

For this reason, in the present invention, thermoplastic synthetic fibers are preferably used as the yarn constituting fibers. As the thermoplastic synthetic fibers, in addition to synthetic fibers made of polyamide, polyester, polyacrylonitrile and the like, low-melting-point easy-adhesion fibers obtained by copolymerizing these with a third component can also be used.

The invention according to claims 5 and 6 of the present invention relates to a method for producing a composite flat integrated yarn, and a part or whole of a plurality of yarns in the width direction becomes irregular. In the preferred embodiment of the present invention, a part or all of a plurality of such yarns are made of thermoplastic synthetic fibers. The thermoplastic synthetic fibers are partially or continuously thermally fused to be integrated. In this case, it is preferable that some or all of the plurality of yarns have different dyeing properties or are colored in different colors. It will stand out. Furthermore, in order to change the Kasuri pattern of the knitted fabric, it is effective to individually move the supply yarns in the manufacturing method.
