Abstract
Thermal protective fabrics and garments are disclosed made from fabrics treated with a fire retardant composition. In one embodiment, the fabrics include a multi-layered construction or a multi-face construction that are treated with the fire retardant composition.
Claims21
A thermal protective garment comprising:
- a jacket or pants including an outer shell material shaped to cover a user's body, the outer shell material comprising a fabric laminate, the fabric laminate including a first outer layer, the first outer layer comprising non-inherently flame resistant synthetic fibers in an amount of at least about 70% by weight based on the weight of the first outer layer, the non-inherently flame resistant synthetic fibers comprising polyamide fibers, polyester fibers, polyolefin fibers, or mixtures thereof;
- a film layer positioned adjacent to the first outer layer, the film layer being comprised of a polyester, a polyurethane, or a polytetrafluoroethylene polymer;
- a second outer layer, the film layer being positioned inbetween the first outer layer and the second outer layer, the second outer layer comprising inherently flame resistant fibers;
- wherein at least the first outer layer contains a flame retardant composition, the flame retardant composition containing at least one flame retardant, the flame retardant comprising a halogen-containing compound or a compound containing phosphorus;
- and
- wherein the fabric laminate has an after flame of less than about 10 seconds when tested according to ASTM Test Method D6413-08.

- and
- wherein at least the first outer layer contains a flame retardant composition, the flame retardant composition containing at least one flame retardant, the flame retardant comprising a halogen-containing compound or a compound containing phosphorus;
- wherein the flame retardant composition is contained in at least the first outer layer in an amount of from about 0.5% to about 20% by weight of the fibers of at least the first outer layer;
- and
- wherein the fabric laminate has an after flame of less than about 10 seconds when tested according to ASTM Test Method D6413-08.
