Flame-resistant nylon/cotton fabric and process for production thereof

摘要

Nylon/cotton blend fabrics containing at least 40% by weight of nylon are rendered flame resistant and durable to multiple launderings in a two step process in which a THP/urea precondensate/ammonia polymer network is formed within the cotton fiber structure then durability is enhanced in a second step 1 which a flame resistant cyclic phosphonate ester and a THP salt plus urea are applied. Durability up to 50 multiple washings and continued flame resistance for these nylon/cotton blend fabrics are reported.
