Abstract: 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.

Abstract: A material and method for treating timber. The material comprises a preservative and a carrier. The carrier is selected such that it remains mobile within the wood and provides for migration of the preservative within the treated wood. By providing a carrier which is mobile within the wood, the timber has a ‘self healing’ effect wherein the carrier/preservative migrates to any freshly cut or exposed surface of the wood to thereby redistribute and treat such a surface within the preservative and hence maintain integrity of a treatment envelope surrounding the wood.

Abstract: The present invention provides a bis(2-pyridinethiol-1-oxide) copper salt coated with one or more compounds selected from glycerin, dialkyl phthalate, lubricating oil, acrylic resin, rosin, fatty acid amide, dialkyl polysulfide, polybutene, paraffin and petrolatum. The coated copper salt does not scatter, so that it is easy to handle, and is superior in safety and workability. In addition, the copper salt does not suffer from any adverse influence on the inherent storage stability or antifouling effect by being coated. Therefore, a coating for the bottom of a ship having a superior antifouling effect and storage stability can be obtained.
