Patent number: 11179583Abstract: A firefighting water garment consists of a reinforced cotton fabric with combing manufactured through weaving of doubled yarn with loose end with an area weight approximately 346 g/m2 which is able to absorb up to six-times more liquid than it weights. The fabric is soaked with a water solution that consists of 50% of water, at least, of 2.7 to 50% of extinguishing agent and of 1 to 10% of a component reflecting heat radiation. Another necessary component is powder titanium dioxide which reflects heat radiation perfectly. Evaporation of water from the suit occurs under presence of fire, and the water starts to cool surface of the fabric and thus prevents overheating of the organism. This way marked extension of time for suit exposure in the fire and prevention of rise of dangerous burns on skin is achieved.Type: GrantFiled: December 18, 2018Date of Patent: November 23, 2021Inventor: Adam Lucanik

Patent number: 7211293Abstract: A closed-loop system and process is used for applying fire retardant chemicals to fibers. Fibers are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. Recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.Type: GrantFiled: November 26, 2003Date of Patent: May 1, 2007Assignees: Gaston International, Inc., Tintoria Piana U.S., Inc.Inventors: Andrea Piana, James L.
