PURPOSE: To obtain the subject conjugate fiber readily producible in a low cost and having a slight color by conjugating a nonelectroconductive layer of fiber-forming polymer with an electroconductive layer comprising thermoplastic polymer and titanium oxide particles having coating film of metal oxide, etc.
CONSTITUTION: (A) A non-electroconductive layer of fiber-forming polymer (e.g. polyamide) is conjugated with (B) an electroconductive layer composed of (i) 15-50wt.% thermoplastic polymer and (ii) 50-85wt.% titanium oxide particles having an electroconductive coating film composed of ≤50wt.% metal oxide (e.g. zinc oxide or tin oxide) and ≤50wt.% metal and/or other metal oxide, preferably in an amount of 5-60wt.% (in conjugated ratio) to afford the aimed conjugated fiber capable of manufacturing white or light colored fiber product or imparting antistatic properties to fiber product in mixing with other electrically charging fiber in a staple state.
