Abstract: The invention relates to the impregnation of clothing, specifically Battle ress Uniforms (BDUs) used by the U.S. Military, with amylopectin fabric wrinkle inhibitor and permethrin insect/arthropod repellent in combination. In one disclosed embodiment of the invention, BDUs are loaded into a field laundry, are rinsed with clear water at 120 degrees Fahrenheit, and amylopectin is applied at a particular concentration. The BDUs preferably are then steam pressed. Permethrin at a predetermined concentration is then applied preferably by the "Individual Dynamic Absorption Application" (IDAA) procedure. The retention of permethrin by clothing treated with amylopectin unexpectedly reveals a substantially higher retention level than clothing without treatment by amylopectin after multiple laundry cycles, providing thereby a dramatic improvement in the insect/arthropod repelling action of the clothing over time.

Abstract: Footwear is tested and evaluated by apparatus which is capable of simulat the actual wearing thereof under various environmental conditions. The apparatus includes a leg pylon and artificial foot which are moved as a unit by apparatus which duplicates the motion of the knee and ankle of an individual. The artificial foot, on which the footwear to be tested is mounted, may be provided with various sensors or condition simulators.
