THE METHOD OF MAKING A BULKED CONTINUOUS FILAMENT YARN COMPRISING COMBINING IN INTERLEAVED RELATION THE FILAMENTS OF A FIRST GROUP OF CONTINUOUS FILAMENTS AND THE FILAMENTS OF A SECOND GROUP OF CONTINUOUS FILAMENTS TO PRODUCE A SINGLE YARN, WITH THE FILAMENTS OF ONE GROUP DISTRIBUTED AMONG THE FILAMENTS OF THE OTHER GROUP AND THROUGHOUT THE YARN, THE SHRINKAGE OF ONE GROUP OF FILAMENTS BEING DIFFERENT FROM THE SHRINKAGE OF THE OTHER GROUPS OF FILAMENTS, AND SUBJECTING THE RESULTING INTERLEAVED BUNDLE OF FILAMENTS TO CONDITIONS ADAPTED TO CAUSE THE HIGHER SHRINKAGE FILAMENTS TO CONTRACT IN LENGTH WHILE THE HIGHER SHRINKAGE FILAMENTS ARE MAINTAINED RELATIVELY STRAIGHT AND TO DRAW UP THE LESS SHRINKABLE FILAMENTS INTO A BULKED STATE, WHEREBY IN THE FINISHED SINGLES YARN CERTAIN FILAMENTS ARE UNIFORMLY CRIMPED THROUGHOUT AT LEAST A PORTION OF THEIR LENGTH TO PROVIDE BULK AND OTHER FILAMENTS ARE IN RELATIVELY STRAIGHT FORM TO PROVIDE DIMENSIONAL STABILITY.
