Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties.
