Abstract
One or more embodiments of the present invention relate to a flame-retardant fabric that includes modacrylic fibers, regenerated cellulose fibers, and heat-resistant fibers. The regenerated cellulose fibers include one or more regenerated cellulose fibers selected from the group consisting of flame-retardant rayon fibers and lyocell fibers. The heat-resistant fibers include one or more heat-resistant fibers selected from the group consisting of polyoxadiazole fibers and aramid fibers. The flame-retardant fabric includes the modacrylic fibers in an amount of 20 to 76 wt %, the regenerated cellulose fibers in an amount of 11 to 48 wt %, and the heat-resistant fibers in an amount of 6 to 69 wt %. The char length, afterflame time, and afterglow time of the flame-retardant fabric measured using a flammability test in accordance with GB/T 5455-1997 are 100 mm or less, 2 seconds or less, and 4 seconds or less, respectively. Thus, provided are a flame-retardant fabric that has favorable flame retardancy and antimicrobial properties, and protective clothing made of the flame-retardant fabric.
