This invention relates to textile substrates to which a finishing treatment has been applied during the manufacturing process. Such a finishing treatment provides improved water and / or oil repellency and stain and soil resistance. The finishing treatment generally includes a repellent agent, a stain release agent, and a particulate component. Other compounds may be added to the treatment, such as stain-blocking agents, crosslinking agents, coupling agents, antimicrobial agents, and pH adjusting agents. The components of the finishing treatment are generally applied to the textile substrate using an application process that results in layered structures on the surface of the treated substrate, which has been found to greatly improve the durability of the treatment. Such treated textile substrates thus exhibit excellent stain and soil resistance and water and / or oil repellency properties.

A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapacitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.
