(54) Deep dyeing helically crimped conjugate yarn process


(57) A deep dyeing helically crimped-conjugate yam is made by high speed melt spinning, preferably with an in-line draw. The drawing step increases the degree of crimp, and the resulting yarn dyes deeper than conventional yams and has greater dye stability than it would have without the drawing step.
