Abstract: A spun yarn of a 100 percent elastic fiber or of an elastic fiber blended with a hard fiber. The yarn is prepared by stretching and heat setting a multifilament yarn or tow of the elastic fiber, stretch breaking, drawing, if necessary, and twisting. The blended yarn is prepared by, after the stretch breaking of the basic elastic fibers and before the drawing, blending with hard fiber roving. The yarn is prepared by employing a modified direct spinning machine equipped with top and bottom aprons in a stretch breaking zone between the back roll and the intermediate roll; the aprons being driven by the revolution of the intermediate roll.
