Aqueous-based Amphiphile Solutions Used as Gel Coatings to Reduce Flammability of Cotton Fabrics



Andre L. Thompson, Brian Love, Rick D. Davis


This study reports on the change in flammability of cotton fabrics caused by water-insoluble gel coatings applied from a single bath solution formulated with polymeric micelles and flame retardant amphiphiles. The flame resistant coatings are made from low concentration aqueous formulations of polyethylene oxide-polypropylene oxide-polyethylene oxide, and 5%-15% w/w melamine and sodium hexametaphosphate. The coated cotton fabrics were tested and characterized by a variety of bench-scale tools, such as vertical flame testing, micro-scale combustion calorimetry, and thermogravimetric analysis. Properties such as increased ignition resistance, self-extinguishment, and higher decomposition temperatures were measured, relative to the uncoated cotton.
