Abstract: The present invention provides a method of forming a polymer-wood composite structure and additive systems for use therein. The method of the invention includes extruding a heated mixture that includes from about 20% to about 80% by weight of a thermoplastic polymer, from about 20% to about 80% by weight of a cellulosic filler material, and from about 0.1% to about 10% by weight of an additive system. The additive system according the invention includes a blend of from about 10% to about 90% by weight of a nonionic compatibilizer having an HLB value of from about 9 to about 19 and from about 10% to about 90% by weight of a lubricant. Use of the method and additive system according to the invention facilitates the production of highly filled polymer-wood composite structures at a very high output rate while maintaining commercially acceptable surface appearance.

Abstract: A plurality of garments are impregnated with an effective amount of permethrin to provide protection against insects by use of a combination of an industrial washing machine and holding tank containing permethrin solution of predetermined strength. The permethrin solution is pumped through the washing machine during washing and returned to the holding tank after the wash cycle is completed. The process is repeated as often as needed. Extracted liquid resulting from a spin cycle to dry the garments after washing may also be circulated to the holding tank and ultimately recirculated.

Abstract: This invention relates to the manufacture of fabric intended to be made into washable garments, and more specifically to the placement of an insecticide such as permethrin in the fabric by impregnation with polymeric binders and a cross-linking agent; or by surface coating with a polymeric binder and a thickening agent to improve the efficacy as an insect repellent and retention of the permethrin in the fabric as an effective insecticide through successive washings of the garments.

Abstract: This invention relates to the manufacture of fabric intended to be made into washable end items, and more specifically to the placement of permethrin in the fabric, as an insecticide, and a synergist for retention of the permethrin in the fabric as an effective insecticide through successive washings of the end items.

Abstract: An insect repellent fabric has a coating containing permethrin and a plasticizer, and a barrier covers the coating to protect the permethrin from degradation by ultraviolet light and oxygen. The barrier may be an acrylic coating or film, aluminum foil, a urethane coating or film, or an outer fabric barrier such as an awning or a tent fly.

Abstract: A tent fabric with a water repellent and flame retardant coating that includes the insecticide permethrin with an effective life of more than six months.

Abstract: A coated fabric that is flame resistant and water repellant includes a polyfunctional isocyanate as an adhesion promoter and binder to adhere the coating to the substrate in a flake proof manner.

Abstract: A lightweight coated fabric weighing no more than 7 ounces per square yard which is resistant to fire, abrasion, water, mildew, and ultraviolet degradation, has a base coat of a urethane binder and fire retardants on both surfaces of a woven synthetic substrate and a top coat bonded to the base coat on both surfaces and containing a polyvinyl chloride binder, fire retardants and chemical compositions resistant to water and ultraviolet degradation.

Abstract: A flame retardant, water-proof fabric useful for tenting, tarpaulins and protective clothing comprises a woven substrate formed from synthetic fibers intimately coated with a homegeneous composition of binders, flame retardants and plasticizers. The composition includes a blocked polyester/polyether urethane prepolymer which, when cured at a temperature sufficient to unblock the urethane, provides strong film integrity to bond the coating to the substrate and thereby increase the effective life of the product.
