WASHFAST INSECT REPELLENT FINISH FOR COTTON FABRICS
Abstract
Deet in various binder systems was applied to cotton fabrics by a padding operation. Because of the low order of fastness found, emphasis has shifted from repellence to mosquitos to toxicity to chiggers and samples were tested for the latter. All but one were tested only after a standardized rinse. Three gave fairly good protection from chiggers: molecular sieve-ethyl cellulose, silicone resin and vinyl copolymer. Four gave fair protection: ethyl cellulose, polyethylene, deet trapped in fiber overpadded with deet-acrylic resin and again overpadded with melamine formaldehyde resin and imine terminated polymer cured at room temperature with carboxyl containing polymer. Four gave poor protection room temperature moisture curing polyurethane, ethyl cellulose overpadded with fluorochemical, carboxy containing acrylic terpolymer and locked in deet. Contrary to results expected from previous experiments, there was one fabric in which deet could not be trapped, presumably be cause of a finish on the fabric.
