It is known that, for example, polyester, polyamide, polyacrylonitrile, polyolefin, nylon, etc., generate significant static electricity due to friction and the like. The generation of static electricity (particularly those with a charged voltage exceeding 10Kv) can lead to quality problems, workability and production problems due to the attraction of dust and objects, secondary disasters due to electric shocks, and insulation breakdown of electronic equipment. Various adverse effects such as these were occurring. For this reason, many proposals have been made for antistatic fibers. For example, side-by-side type or core-sheath type composite fibers consisting of a conductive component and a non-conductive component are effective fibers for preventing static electricity, and are

It has been proposed in Japanese Patent Publication No. 57-25647, Japanese Patent Publication No. 56-189816, Japanese Patent Application Laid-open No. 57961-1984, and the like. However, when the conductive component of the fiber is completely covered with a non-conductive component, the conductivity is poor, and dielectric breakdown of the non-conductive component covering the conductive component of the fiber is required. Therefore, a fiber described in Japanese Patent Application Laid-open No. 174469/1983 has been proposed as a fiber that should solve these problems.

生じていた。(Problem to be Solved by the Invention) However, in this conductive composite fiber, when the sheath component on the eccentric side of the core component is removed by a solvent, a part of the core component is removed over the length of the fiber. It is configured to be exposed along the horizontal direction. Therefore, the exposed portion of the core component on the peripheral surface of the fiber is formed according to the position and shape of the core component that are predetermined before manufacturing the composite fiber. As a result, as the exposed portion increases, the shape of the core component becomes more complicated, resulting in a problem that the production of the fiber becomes more complicated.

Further, a part of the conductive component is cut and protrudes from the sheath material made of non-conductive resin to the fiber surface.

被覆されている。 As shown in FIGS. 1 and 2, the core material 12 is composed of a bundle of fibrous conductive components 13. As the fibrous conductive component 13, conductive powders such as powdered carbon, simple substances such as metals, metal oxides such as tin oxide and zinc oxide, and metal compounds such as copper sulfide and zinc sulfide, polyethylene, polypropylene, etc. , polystyrene, polybutadiene, polyisoprene, nylon-6, nylon-66, polyethylene terephthalate, polybutylene terephthalate and other thermoplastic polymers and melt-spun. The mixing ratio of the conductive powder to the thermoplastic polymer varies depending on the type of the conductive powder, but a weight ratio of 1 part thermoplastic polymer to 3 parts conductive powder is preferable. However, if the amount of conductive powder mixed is too large, it will not be possible to mix the conductive powder sufficiently with the weight body, so it is necessary to appropriately determine the amount of conductive powder mixed. The core material 12 is constructed by bundling a plurality of conductive components 13 (preferably 3 to 5) thus configured. The core material 12 is covered with the sheath material 14 so as to be placed in the center thereof.

Polymers, polyolefins such as polyurethane and polypropylene are suitable. Core material 1 formed by bundling the conductive components 13 with this non-conductive resin
2 is surrounded and covered to form a fiber with a core-sheath structure. Here, the sheath material 1 of the core material 12
Although the coating according to No. 4 may be done by any conventionally proposed method, in this example,
By melting the non-conductive resin constituting the sheath material 14 and immersing the core material 12 in this melt, resin is spread between the surface of the core material 12 and the conductive component 13 constituting the core material 12. A method was used in which a coating layer was formed by impregnation and cooling and solidification.

た繊維を通過させることにより行なつた。 A part of the conductive composite fiber 11 forming this core-sheath structure is cut, and a part of the core material 12 disposed at the center of the fiber protrudes from the surface of the fiber. Any method may be used to cut the fibers, but in this example, electrical discharge machining was used. That is, the test was carried out by running the fiber under constant tension at a speed of 5 to 10 m/min and applying a voltage of 10 to 20 Kv. At this time, the depth of the cut portion depends on the thickness of the sheath material 14, but is deep enough to cut at least one of the conductive components 13 that constitute the core material 12 arranged in the center of the fiber. It needs to be disconnected. Therefore, the thickness of the sheath material 14 that covers the core material 12 is preferably as thin as possible. However, if the thickness of the sheath is reduced over the entire fiber, the strength and elongation will decrease. Therefore,
It needs to be thick enough to maintain its elongation and strength as a fiber. The cut fibers are transferred to the core material 12
A part of the conductive component 13 constituting the core material 12, especially the core material 12
The tip and/or the vicinity of the tip of the conductive component 13 disposed on the outside of the conductive component 13 protrudes from the fiber surface in a state of expanding outward, so that the fiber as a whole has a raised appearance. Further, the conductive component 13 of the core material 12 is cut, and the sheath material 14 is also hollowed out around the protruding portion of the conductive component 13. In this example, the entire outer surface of the sheath material 14, that is, the outer surface of the non-conductive resin constituting the sheath material 14, is further removed by the solvent, and the fiber as a whole becomes thinner than when it was cut. Therefore, as the core material 12 becomes thinner, the protruding portion of the conductive component 13 of the core material 12 increases, and the conductive performance is further improved. Sheath material 14 made of solvent
The removal of the fibers was carried out by passing the cut fibers through an atmosphere of the solvent to be removed, although any conventionally proposed method may be used.

Therefore, in the case of the mat 22 for automobiles, static electricity generated by contact with shoes or clothes is absorbed by the static electricity neutralizing paper 23 arranged in the mat 22 by the conductive composite fibers 11 contained in the pile 24. Guided by this neutral Japanese paper 23
It is designed to be discharged in the air by In addition, static electricity is also discharged into the air from the tips of the conductive components 13 protruding from the surface of the conductive composite fibers 11 included in the pile 24. As a result, static electricity generated by friction can be efficiently disposed of.

る。(Effects of the Invention) As detailed above, in the conductive composite fiber according to claim 1, the fibrous conductive components constituting the core material disposed in the center of the fiber are bundled together and It is in contact. Further, a part of the conductive component is cut and protrudes from the sheath material made of non-conductive resin to the fiber surface. Therefore, static electricity generated due to friction or the like is guided by the conductive component protruding from the fiber surface to other conductive components constituting the core material, resulting in conductivity. As a result, it can be obtained by a simpler method than conventional conductive composite fibers, and can maintain conductivity for a longer period of time.

It is starting to increase. Therefore, even if a portion of the protruding conductive component is worn out due to friction or the like, the conductivity does not decrease, and the conductivity can be maintained for a long time.
