Processing technology of the flame retardant product of polyacrylonitrile oxidized fibers

PANOF fibers were processed by means of rotor spinning technique so as to improve their spinnability and properties of the yarns.The relationship between process parameters and yarn quality was researched through spinning trials and comparison,and for enhancing the yarn quality,processing parameters were optimized. The flame retardant fabric developed with rotor spun PANOF yarns was obviously superior to that with ring spun yarns.
