Abstract (en)
The present invention pertains to a conjugate fiber bundle characterized by being constituted by conjugate fibers comprising at least two types of polymers having different melting points, and by being such that the variation coefficient CV for the value of the ((distance between polymer centers of gravity)/(fiber diameter)) among the conjugate fibers is 5-30%.
