Sweaters and fleeces made of acrylic fibers are subject to static electricity when you take them off after wearing them. In order to prevent the generation of static electricity, there is a demand for conductive yarns that can be mixed with acrylic fibers.
In order to meet this demand, it is conceivable to mix acrylic fibers with conductivity, and some have been proposed in the past (see Patent Documents 1 and 2).

However, the production of acrylic conductive yarn is very problematic. A method for producing an acrylic conductive yarn is a method in which conductive particles are added to an acrylic resin, for example, a spinning stock solution is prepared by dissolving an acrylic polymer and conductive particles such as conductive titanium oxide in an organic solvent. There is a complicated method of discharging into the inside and spinning by a semi-dry method, and after-treatment to remove the solvent. When this solvent is removed, voids are generated in the acrylic fiber itself, which adversely affects the conductivity.
What can be considered there is a conductive yarn of another material. However, if conductive yarns of other materials are mixed with acrylic fibers, two steps of dyeing acrylic fibers and dyeing other materials are required.
The problem to be solved by the present invention is to provide a composite conductive fiber that has few problems in making it conductive and can be dyed under the same conditions as the acrylic fiber.

The present invention relates to a composite conductive fiber comprising a non-conductive layer and a conductive layer, wherein the non-conductive layer occupies at least 70% of the fiber surface, and the non-conductive layer includes a metal sulfonate group-containing isophthalic acid and a polyalkylene glycol. And the conductive layer is a composite conductive fiber that is a thermoplastic polymer containing titanium oxide particles having a conductive coating, and the above-described problems have been solved by constituting in this way.

That is, as a result of intensive studies on conductive yarns, the present inventors focused on composite conductive fibers by melt spinning in order to obtain conductive fibers that can be dyed in the same way as acrylic fibers and have few manufacturing problems. The present invention has been achieved by making the polymer of the non-conductive layer on the surface of the composite conductive fiber into a polymer that can be dyed under the same conditions as acrylic, i.e., capable of atmospheric pressure cationic dyeing.

The composite conductive fiber of the present invention can be easily and inexpensively produced industrially, can be dyed at normal pressure, and has good color development. Therefore, when mixed with an acrylic material, it generates static electricity in the product. And can be dyed under the same conditions as the acrylic fiber.

The nonconductive layer of the composite conductive fiber of the present invention is a polyester obtained by copolymerizing a metal sulfonate group-containing isophthalic acid and a polyalkylene glycol.
The metal sulfonate group-containing isophthalic acid (hereinafter referred to as SIP) is preferably 0.5 to 10 mol% with respect to the acid component contained in the polyester of the nonconductive layer. SIP is 0
. When the amount is less than 5 mol%, the cation dyeability is lowered, and the dyeing is not performed under the same conditions as acrylic.
When mixed and dyed, the conductive fibers tend to appear as spots. In addition, SIP is 10
When it exceeds mol%, the degree of polymerization does not progress, the molecular weight of the polymer does not increase, and even when spun, there is a tendency that it does not become a yarn.
Examples of SIP include dimethyl 5-metal sulfoisophthalate (hereinafter referred to as SIPM) or a compound obtained by esterifying a dimethyl group with ethylene glycol (hereinafter referred to as SIPE). It is preferable to employ SIPE because if a large amount of SIPM is added to the slurry tank, the physical properties of the slurry may be deteriorated.
Further, examples of the metal in SIP include sodium, potassium, lithium and the like, and most preferred is sodium.

Moreover, it is preferable that polyalkylene glycol is 1.5 to 6 weight% with respect to polyester of a nonelectroconductive layer. If the polyalkylene glycol is less than 1.5% by weight, the dyeability under normal pressure is inferior, and high-pressure dyeing is required. If mixed with acrylic and dyed at normal pressure under the same conditions, conductive yarn is dyed. Concentration is low and tends to look like spots. On the other hand, if the polyalkylene glycol exceeds 6% by weight, the degree of polymerization does not progress, the molecular weight does not increase, and there is a tendency that even when spinning, the yarn does not become a yarn.

The average molecular weight of the polyalkylene glycol is preferably 150 to 1000.
If the average molecular weight of the polyalkylene glycol is within the above range, the dyeing effect at about 100 ° C. under normal pressure is exhibited, and the thickening action due to the sulfonate group is reduced because the polyalkylene glycol exhibits a plastic effect. Therefore, it is possible to increase the degree of polymerization of the polymer.
The polyalkylene glycol is represented by the general formula HO (CnH2nO) mH (where n and m are positive integers), and polyethylene glycol of n = 2 is general-purpose and most preferred.

This DEG is generated by a side reaction during polymerization. If it is less than 4.5 mol%, the atmospheric pressure cationic dyeability is inferior. Also, 6.0
When it exceeds mol%, the heat resistance and oxidation resistance of the polymer are inferior, and the operability during melt spinning is remarkably deteriorated.
The terminal carboxyl group concentration of the polymer is preferably 20 to 30 equivalent / ton. When the terminal carboxyl group concentration is less than 20 equivalents / ton, the color of the polymer extruded from the polymerization tank is poor, and when it exceeds 30 equivalents / ton, the heat resistance in the spinning process and the subsequent process is deteriorated.
