Abstract

PURPOSE: Magnetic fiber, containing a magnetic layer consisting of a synthetic polymer containing magnetic particles combined with a protective layer consisting of a fiber-forming polymer, easily obtainable in a few steps, and suitable for iron cores, e.g. coils and recording materials.
CONSTITUTION: 0.2wt% or more magnetic particles consisting of a metal, alloy or oxide thereof containing iron, nickel and cobalt is principal components is mixed with a synthetic polymer, e.g. polyamide, having a softening point of 80W250°C as a binder to form a magnetic layer 1, which is then joined to a protective layer 2 consisting of a fiber-forming polymer, e.g. polyamide, having a softening point of 150°C or above and 30°C or more higher than that of the polymer at a composite ratio in the range of (90/10)W(10/90), preferably (20/ 80)W(80/20), in the form of the sheath-core type or side-by-side type.
