摘要： A conductive sheath-core conjugate fiber having its sheath component constituted of a conductive layer of thermoplastic polymer (A) containing conductive carbon black microparticles and having its core component constituted of a protective layer of fiber forming thermoplastic polymer (B), characterized in that the ratio of polymer (A) based on the total weight of polymers (A) and (B) is in the range of 10 to 35 wt.%, and that the ratio of L 1 /L 0 , wherein L 1 is the length of interface between the core component and the sheath component in a cross section of the conjugate fiber while L 0 is the length of circumference of perfect circle having a sectional area of the same size as that of the core component, is in the range of 1.04 to 10.0, and that the fineness, breaking strength and breaking elongation thereof fall within given ranges, and that the shrinkage ratio thereof in 100°C water is within a given range, and that the fiber surface covering ratio of the sheath component is 85% or above. Accordingly, there is provided a conductive sheath-core conjugate fiber that exhibits excellent electricity removing performance, having substantially no deterioration of electricity removing performance even when continuously worn for a prolonged period of time, and that maintains the performance thereof over a prolonged period of time, excelling in durability. Furthermore, there is provided a process for producing the same, and provided a dustproof cloth utilizing the above fiber.

摘要： Disclosed is a conductive composite fiber having an elongation (DE) of 100-350%, wherein a conductive layer (A) composed of 60-80% by weight of a thermoplastic resin and 20-40% by weight of a conductive particle, and a protective layer (B) composed of 50-95% by weight of polyethylene terephthalate and 5-50% by weight of polyethylene-2,6-naphthalate are combined. Consequently, this conductive composite fiber has excellent conductivity. In addition, this conductive composite fiber is small in changes over time in fiber properties such as elongation and boiling water shrinkage during transportation or storage, although it has a certain or more elongation.
