A continuous bi-compound bulky yarn consisting of a pair of acrylic polymeric components differing from each other in some of their properties is prepared by spinning those components in solution to produce a spun yarn which is drawn and then, successively, passed through a first oven heated to a temperature in the range of 130 DEG -250 DEG C, subjected to a false twist by means of a rotating spindle, passed through a second oven heated to a temperature in the range of 120 DEG -240 DEG C, and wound on a holder.
