Abstract
Protective garments are disclosed having a fabric material treated with a durable water resistant treatment. In accordance with the present disclosure, the durable water resistant treatment is substantially free of fluorocarbon chemicals and yet provides not only excellent water resistance, but also has excellent durability properties.
Claims17
A protective garment comprising:
- a fabric material that forms at least a portion of the protective garment, the fabric material comprising inherently flame resistant fibers, the inherently flame resistant fibers comprising at least one of para-aramid fibers, meta-aramid fibers, polybenzimidazole fibers, or poly(p-phenylene-2,6-bezobisoxazole) fibers, the fabric material being impregnated with a durable water resistant treatment, the fabric material containing fluorocarbon chemicals in an amount less than 0.1% by weight of the fabric material, the durable water resistant treatment being incorporated into the fabric material such that the fabric material maintains a spray rating of at least 70 after ten laundry cycles, the durable water resistant treatment comprising a dried and cured finish, the dried and cured finish being formed from a polyurethane polymer, a blocked isocyanate, an acrylic polymer, a wax, and optionally a softener, the polyurethane polymer comprising an anionic polyurethane that is aqueous dispersable, wherein the polyurethane polymer comprises an aliphatic polyester/ether polyurethane polymer, and further wherein the dried and cured finish comprises about 10% to about 50% by weight of the polyurethane polymer and about 10% to about 70% by weight of a combination of the acrylic polymer and the wax.
A protective garment comprising:
- a fabric material that forms at least a portion of the protective garment, the fabric material comprising inherently flame resistant fibers, the inherently flame resistant fibers comprising at least one of para-aramid fibers, meta-aramid fibers, polybenzimidazole fibers, or poly(p-phenylene-2,6-bezobisoxazole) fibers, the fabric material being impregnated with a durable water resistant treatment, the fabric material containing fluorocarbon chemicals in an amount less than 0.1% by weight of the fabric material, the durable water resistant treatment being incorporated into the fabric material such that the fabric material maintains a spray rating of at least 70 after ten laundry cycles, the durable water resistant treatment is a dried and cured finish and is formed from a durable water resistant treatment consisting of an aqueous dispersable and anionic polyurethane polymer, a blocked isocyanate, an acrylic polymer, optionally a wax, optionally a softener, water, and optionally a wetting agent, wherein the polyurethane polymer is an aliphatic polyester/ether polyurethane, and further wherein the dried and cured finish comprises about 10% to about 50% by weight of the polyurethane polymer and about 10% to about 70% by weight of a combination of the acrylic polymer and the wax.
