Abstract: PURPOSE:To produce an acrylic yarn not causing the mutual adhesion of single filaments and useful for carbon fibers, etc., superior in productivity of its production facility by subjecting a specific yarn to a drawing treatment in a hot water bath and subsequently nipping the drawn yarn at a yarn temperature of =2000, the index M being represented by an equation: M=(the substantial total deniers [d] per yarn fed into the drawing in the bath)/(the width [mm] of the yarn per yarn), and has a single filament number of >=3000 per yarn.
