Abstract
Novel block copolymer formed by melt blending a melt spinnable polyamide such as nylon-6 and a poly(dioxa-amide) such as poly(4,7-dioxadecamethylene adipamide) which is also known as N-30203-6 is disclosed. Said copolymer has utility as a fiber. The fiber of disclosed copolymer, for example, of nylon-6 and said poly(dioxa-amide) has moisture absorption characteristics similar to that of cotton. Resulting copolymer is also known as N-30203-6//6. Furthermore, the resulting fiber still maintains the other desirable properties of the major constituent, for example, nylon-6.
