るという欠点があった。(Prior Art) It is generally known that both synthetic fibers and natural fibers are charged by friction. In particular, the triboelectric charging of synthetic fibers is awkward, and is remarkable in winter when the humidity is low and causes various kinds of static electricity damage. It is known that, in order to improve such a problem, an antistatic property is conventionally imparted by mixing a conductive fiber or the like with a fiber material. As a specific method, in the case where the conductive fiber is simply blended with the non-conductive fiber and used, the conductive fiber is exposed on the yarn surface, impairs aesthetics, and the conductive fiber is applied to the surface layer of the yarn. There is a drawback that the feel is bad due to the location, and that the durability of the antistatic performance is reduced.

Further, a conductive yarn having a core as a core and a non-conductive short fiber as a sheath (Japanese Patent Publication No. 61-42012) is known. However, even in these methods, the core portion is easily exposed because the core portion and the sheath portion are easily displaced, and not only the aesthetics are impaired, but also when the fabric using the yarn is dyed and finished, the color hue unevenness (so-called eyes ). Further, the strength of the yarn is liable to decrease with the exposure as described above, and there is a serious problem such as yarn breakage during weaving.

Specifically, for example, carbon fibers such as carbon fibers and graphite fibers as well as metal fibers such as stainless steel fibers and aluminum fibers, and conductive fine particles (metals, metal oxides, carbon black, etc.) are partially embedded in the synthetic fibers. Or a so-called core-sheath type conductive filament yarn dispersed or uniformly dispersed in the core, or metal on the surface of the synthetic fiber,
Examples include conductive fibers coated with metal oxides, carbon black, and the like. The conductive filament yarn of the present invention may be a monofilament or a multifilament, and is not particularly limited, but is preferably selected in consideration of the linear density when blending by the interlacing method described later.

限定され好ましくない。The non-conductive staple used in the present invention is made of a natural fiber, a synthetic fiber, or a blend thereof. The raw cotton for spun yarn is shown, and the fineness of the raw cotton, the fiber length, etc. may be any as long as the restrictions of the machine used for the production allow. The non-conductive staple of the sheath surrounds the outer layer of the mixed fiber of the core, and further, the core and the sheath are united to form a twist coefficient (inch method) of 1.5 to 5.0.
It must be twisted. If the number of twists is less than 1.5, the covering properties of the core-sheath portion will be insufficient and the conjugation force will decrease.If the number of twists exceeds 5.0, the conjugation force will improve, but on the other hand, the physical properties of the composite yarn will decrease and the texture will be hardened, It is not preferable because the application for use is limited.

Furthermore, in the present invention, the non-conductive staple is 50 to 50 in the antistatic composite yarn.
It needs to account for 90% by weight. If the non-conductive staples are less than 50% by weight, the hue of the core is conspicuous and the appearance is deteriorated. If the content exceeds 90% by weight, the effect of the antistatic property decreases, which is not preferable. Performance as antistatic composite yarn (antistatic),
The preferable range of the non-conductive staple which becomes the sheath from the viewpoint of physical properties, hue and appearance is 60 to 85% by weight.
ここで、本発明の制電性複合糸の製造法について簡単
に説明する。Here, the method for producing the antistatic composite yarn of the present invention will be briefly described.
まず、導電性フィラメント糸と非導電性マルチフィラ

レース法が好ましい。First, the conductive filament yarn and the non-conductive multifilament yarn are interlaced (Japanese Patent Publication No. 36-12230,
The fibers are mixed according to Japanese Patent Publication No. 37-1175). As a method for producing the mixed yarn, there is also an electric mixing method. However, since a high voltage of 1000 to 5000 volts is applied, problems such as generation of sparks in the conductive filament yarn are likely to occur, and the interlace method is preferable.
なお、インターレース法は以下に述べるように空気力
を用いて均一に混繊されるため上記問題を解決できるも
のであり生産性も高い。In addition, the interlace method can solve the above-mentioned problem because the fibers are uniformly mixed by using the aerodynamic force as described below, and the productivity is high.

ある。The interlacing method creates two or more turbulent turbulence zones almost parallel to the yarn axis, guides the filament yarns in this zone, and applies tension so that loops and crimps do not occur to produce a tight non-bulky yarn. Technology. Of particular interest in interlacing are overfeed ratio, tension, fluid pressure and denier, and number of filaments.
導電性繊維は一般に非導電性マルチフィラメントに比

や高く好ましくは１〜５％に設定することが重要であ
る。Since the conductive fiber generally has a higher density and modulus than non-conductive multifilaments, it is important to set the overfeed rate to be slightly higher, preferably 1 to 5%.
均一な混繊は乱流域内における各成分の線密度をでき
るだけ近くすることが好ましい。It is preferable that the uniform fiber mixing make the linear density of each component in the turbulent flow region as close as possible.

のであった。As described above, according to the present invention, the mixed yarn composed of the conductive filament yarn and the non-conductive filament yarn is located at the core of the antistatic composite yarn, and the core is covered with non-conductive staples. An antistatic composite yarn is obtained, and this yarn provides a product excellent in appearance with excellent physical properties and weaving properties. Further, the fabric using the antistatic composite yarn could impart not only the antistatic property but also excellent characteristics without color hue unevenness after dyeing.
