ABSTRACT OF THE DISCLOSURE Novel block copolymer formed by melt blending a melt spinnable polyamide such as nylon 6 and a poly(oxa- amide) such as poly(4-oxaheptamethylene adipamide) (also known as 303-6) is disclosed. Said copolymer has utility as a fiber. The fiber of copolymer, for example of nylon 6 and said poly- (oxa-amide) has superior absorption characteristics than that of nylon 6. Furthermore, resulting fiber still substantially maintains the other desirable properties of the major con- stituent, for example nylon 6. -1-
