    摘要: Continuous filaments are subjected to treatments to produce in the axial direction of each filament alternating and repeating high shrinkage segments and low shrinkage segments. Yarns and fabrics produced from the filaments will bulk out in the low shrinkage segments by the shrinkage of the high shrinkage segments upon being subjected to a relaxation treatment.
