In order to develop a fabric with excellent flame resistance function,antistatic function,moisture absorption and breathability,the polysulfonamide(PSA)fiber and the flame retardant viscose(FRV)fiber were blended.Meanwhile,the conductive filaments were used as the core yarn,and then they were made into the core-spun yarn and the fabric at different blending ratios of PSA/FRV.The effects of the blending ratio of PSA/FRV on the mechanical properties and the evenness of the yarn were studied.The effects of the blending ratio of PSA/FRV on mechanical properties,flame retardant properties,antistatic properties,moisture permeability and drape of the fabric were analyzed.With the increase of the blending ratios of PSA/FRV,the strength and the elongation of the core-spun yarn increased firstly and then decreased.Moreover,the evenness of the core-spun yarn was improved,the fabric strength increased firstly and then decreased,the flame resistance decreased,and the antistatic performance improved.These results provide an important basis for the preparation and wide application of fabrics made of PSA/FRV/conductive filament.
