Zusammenfassung: | To provide an electroconductive fiber having sufficient electrical conductivity even when blended or drawn during manufacture of BCF and no noticeable black streak when used for a carpet.SOLUTION: An undrawn electroconductive composite fiber includes an electroconductive layer consisting of a polyamide containing an electroconductive carbon black of 20 mass% or more and 45 mass% or less, and a protective layer consisting of a polyamide containing a concealing inorganic pigment of 5% or more. A fracture elongation is 200% and 600%, a linear resistance value is 1.0E+05 to 9.9E+07 Ω/cm, and a ratio of an exposed circumference length of the electroconductive layer to a total circumference length of a cross-section of a fiber is less than 8%.SELECTED DRAWING: None
【課題】BCF製造時に混繊、延伸されても十分な導電性を有しており、カーペットに使用された際に黒筋が目立たない導電糸を提供する。【解決手段】導電性カーボンブラックを20質量%以上、45質量%以下含有するポリアミドからなる導電層と、隠ぺい性無機顔料を5質量%以上含有するポリアミドからなる保護層とを有し、破断伸度が200〜600%であり、線抵抗値が1.0E+05〜9.9E+07Ω/cmであり、繊維横断面の全周長に対する導電層の露出周長の割合は8%未満である未延伸導電性複合繊維である。【選択図】 なし |
