  • Flame retardant fabrics and process to make same
    Patent number: 10633789
    Abstract: A flame retardant fabric wherein a flame retardant composition is applied to the fabric while the fabric is being stretched. Preferably, the fabric is a blend of cotton and a thermoset. Carbon fibers may be included to impart anti-static properties. The present invention includes a method of treating a woven or knitted fabric of cotton blended with a thermoset, or with a thermoplastic, or with both with a flame retardant composition comprising the steps of stretching the fabric up to 12% greater than its un-stretched dimensions and, while so stretched, applying a flame retardant to the fabric and then allowing the fabric to shrink back to its approximate original dimensions. The flame retardant may either be applied to the fabric or the fabric may be immersed in an aqueous bath containing flame retardants.
