Abstract
A method of manufacturing composite fibers comprising the steps of separately melting two different synthetic linear polymers having the ability to form fibers, and forming a single fiber by simultaneously extruding said polymers from the same orifice of a nozzle, such that said two types of polymers may be disposed eccentrically with respect to each other within arbitrary arbitrary cross section of the obtained fiber, said method being characterized in that one of said polymers essentially consists of a homopolyamide having an inherent viscosity of 0.8 or more, and the other polymer consists of a copolyamide such as those having an inherent viscosity of not less than 1.2 and less than that of said homopolyamide, said copolyamide, with respect to said homopolyamide, in equilibrium ratio of melting point and viscosity, being the difference between the melting point of said homopolyamide and that of di copolyamide of 80º C or less, and said copolyamide being formed of a polymer whose main constituent is contained in the proportion of 75% or more by weight, while at least one of the copolymer constituents contained in said copolymer is present in the copolymer. proportion of 3% or more in weight.
