Abstract
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.degree.-250.degree.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.degree.-240.degree.C, and wound on a holder.

Method for the production of a bulky acrylic bi-compound, continuous yarn consisting of a pair of acrylic polymeric components differing from each other in some of their properties, characterized by from 4 to 15 waves per centimeter and a crimping rate ranging from 5% to 20%, wherein the yarn is drawn, the drawn yarn is passed through a first oven heated to a temperature in the range from 130.degree.C to 230.degree.C, is then subjected to a false twist by means of a rotating spindle, is then passed into a second oven, heated to a temperature of from 120.degree.C to 200.degree.C, and is then wound on a holder.
