摘要：
Acrylic synthetic fibers highly resistant to pilling and having good dyeability can be produced by specifying the composition of the acrylic polymer, the condition of the primary stretching step, the internal water content of the water-swollen gel fibers, the conditions of the steps of the drying-compacting, secondary stretching and relaxing heat treatment.
