Abstract
A process for the production of a foam rubber tree bark-configured article having a manmade textile backing is provided. The inventive process involves the vulcanization of NBR or SBR including a chemical blowing agent, and optionally including EPDM as an ozone-resistance agent, over a silicon-base mold which is a negative relief mold of at least a portion of tree bark, and with a backing adhered to, and not easily removed from, the unmolded side of the rubber. Such a backing is either 100% polyester or 100% nylon, which provides an excellent, long-lasting, durable, easily colored, fast-drying article for use in outdoor camouflage applications. The article itself, as well as clothing, footwear, and shelter articles incorporating the inventive product, are also provided.
