Processes of forming a fiber article and articles formed therefrom are described herein. The processes generally include providing a propylene-based polymer; contacting the propylene-based polymer with polylactic acid in the presence of a reactive modifier, a non-reactive modifier or a combination thereof to form a polymeric blend, wherein the reactive modifier is selected from epoxy-functionalized polyolefins and the non-reactive modifier comprises an elastomer; and forming the polymeric blend into a fiber article.
