ABSTRACT:
Novel block copolymer formed by melting blending a melt spinnable polyamide such as nylon-6 and a poly(oxa-amide) such as poly(4-oxaheptamethylene adipamide) (also known as N-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 (N-303-6//6) still substantially maintains the other desirable properties of the major constituent, for example nylon-6.
