Multifunctional Textile Coating of Military Fabrics

This STTR Phase I project will develop a novel multifunctional coating to combat a wide range of threats in a variety of complex situations for the warfighter. Military combat uniforms currently use NYCO fabrics (Nylon/cotton 50/50). The US Army is seeking new coating technologies that will impart multifunctional properties such as antistatic, conductive, flame resistance, improved abrasion resistance, and ballistic/stab protection to existing NYCO fabric clothing systems. Fire resistant fabrics are expensive because they are made using special fibers. Imparting fire and heat resistance property to the NYCO fabrics by simple FR coatings is a cost-effective approach. This can also help extend their use in other advanced military textile applications such as tents, tarpaulin covers and flight gear. Recent studies have shown that ionic liquids have excellent thermal and fire resistant properties. Since ionic liquids contain charged species they can also exhibit excellent antistatic properties. In the proposed Phase I effort, a new multifunctional coating based on ionic liquids will be developed for military fabrics. MMI has significant experience in the development of ionic liquids for specific end applications. The multifunctional NYCO fabrics treated in Phase I will be tested for vertical flame resistance, antistatic testing, mechanical durability and launderability. In the Phase II effort, the coating composition and process will be optimized for producing multifunctional fabrics for specific military gear that will be field tested.
