High Char Yield Multifunctional Textile Finishes

A need exists for advances in non toxic treatments for cover and barrier fabrics. Since polybrominated materials have been banned in many European countries and the production of a number of brominated additives terminated in the U.S. as well, future technologies must focus on non-halogenated treatments. In general, non-halogenated treatments (phosphates and borates) are not durable to aqueous solutions. Barrier fabrics are useful in reducing the risk of fires, however many of the synthetic polymers used in them do not form cohesive char layers or they experience significant shrinkage during initial exposure. This allows holes to form, allowing for off gassing and continued burning of underlying foam. During this program, Luna will develop a durable non-halogenated flame retardant treatment applicable to both barrier fabrics and cover fabrics. This treatment will significantly improve char yields of the barrier fabric. Cover fabric samples will exhibit improved fire performance and stain resistance.
