  • Patent number: 11761124
    Abstract: An elastic flame-resistant yarn containing an intimate fiber blend of staple fibers wrapped around a plurality of elastic continuous fibers. The intimate fiber blend of staple fibers contains non-flame-resistant (FR) cellulosic fibers, modacrylic fibers, and aramid fibers. The non-FR cellulosic fibers constitute at least about 31% by weight to at most about 54% by weight of the intimate fiber blend of staple fibers, the modacrylic fibers constitute at least about 30% by weight to at most about 49% by weight of the intimate fiber blend of staple fibers, and the aramid fibers make up at least about 3% by weight to at most about 20% by weight of the intimate fiber blend of staple fibers. The elastic continuous fibers make up at least about 0.01% by weight to at most about 5% by weight of the elastic flame-resistant yarn.
