Composite Fiber And Multifilament

Abstract: The present invention provides a composite fiber wherein the sum of the lengths of interfaces that are formed by two or more kinds of polymers that constitute a fiber cross-section is extremely large. A composite fiber according to the present invention has a fiber cross-section which is composed of two or more kinds of polymers that form a plurality of interfaces; the value obtained by dividing the sum of the interface lengths between two kinds of polymers by the area of the fiber cross-section is 0.0010 nm-1 or more; and the interfaces are continuous in the fiber axis direction.
