ABSTRACT:
Novel copolymer formed by melt blending a melt spinnable polyamide, such as nylon-6, and a block of random poly(dioxa-amide), such as a copolymer prepared from the mixture of caprolactam and the salt of adipic acid and 4,7-dioxadecamethylene diamine, is disclosed. The resulting copolymer, N-30203-6/6//6, has utility as a fiber. The fiber, for example, resulting from melt blending of nylon-6 and the aforementioned random poly(dioxa-amide) has moisture absorption characteristics similar to that of cotton. Furthermore, the resulting fiber still maintains the other desirable properties of the major constituent, for example, nylon-6.
