Flame-retardant fabric and protective clothing made of the same

Abstract

The present invention relates to a flame-retardant fabric that includes modacrylic fibers, one or more of regenerated cellulose fibers selected from the group consisting of flame-retardant rayon fibers and lyocell fibers, and polyimide fibers. The flame-retardant fabric includes the modacrylic fibers in an amount of 26 to 79 wt%, the regenerated cellulose fibers in an amount of 18 to 48 wt%, and the polyimide fibers in an amount of 3 to 26 wt%. The polyimide fibers have a fiber length of 45 to 127 mm. The char length measured by a flammability test based on GB/T 5455-1997 is 50 mm or less. The present invention also relates to protective clothing made of the flame-retardant fabric. Thus, the present invention provides a flame-retardant fabric whose char length is short in a flammability test and that has favorable flame retardancy, and protective clothing made of the flame-retardant fabric.
