Flame retardant textile fabric

A textile product having flame retardant properties, said textile product comprising a woven or knitted fabric comprised of yarns of rayon continuous, non-texturized filaments, the yarns having outer filaments along the periphery of the yarn and inner filaments in the interior of the yarn, a cured insoluble hydroxymethyl phosphonium flame retardant compound present on the fabric at an add-on level of at least 20% by weight of the fabric and imparting flame retardant properties to the fabric, and wherein the outer filaments of the yarns are adhered to one another by said cured insoluble flame retardant compound, and the inner filaments of the yarns have a phosphorus content in cores of the inner filaments that is at least 50% of the phosphorous content in cores of the outer filaments, and wherein the textile product meets the vertical flammability requirements as set forth in ASTM D 6413.

A garment for direct contact with the skin of a wearer, the garment having hydrophilic properties for wicking moisture away from the skin of the wearer and having low friction properties to avoid chafing, said garment comprising a woven or knitted fabric formed of yarns of rayon continuous, non-texturized filaments, the yarns having outer filaments along the periphery of the yarn and inner filaments in the interior of the yarn, a cured phosphorus-based flame retardant compound durably affixed to the filaments and imparting flame retardant properties to the fabric, and wherein the inner filaments of the yarns have a phosphorus content in cores of the inner filaments that is at least 50% of the phosphorous content in cores of the outer filaments, and wherein the garment meets the vertical flammability requirements as set forth in ASTM D 6413.
