The subject of this invention is a method for producing a totally impregnated, coated yarn structure. According to the method, a carded roving containing two varieties of staple fiber, each having a different melting point, is drawn through a tapering die heated to a temperature sufficient to melt only the staple fibers of the variety having the lower melting point. The molten liquid so produced coats and impregnates the staple fibers of the other variety. The tapering die provides the compression needed to impregnate these fibers and to drive out any air trapped between them. The yarn obtained by practicing this method is also claimed.
