Abstract
Disclosed are technical fibers and yarns made with partially aromatic polyamides and a fiber having vapor phase action such as an FR cellulosic fiber. Fabrics made from such fibers and yarns demonstrate superior flame retardancy over traditional flame retardant nylon 6,6 fabrics. Further, the disclosed fibers and yarns, when blended with other flame retardant fibers, do not demonstrate the dangerous “scaffolding effect” common with flame retardant nylon 6,6 blended fabrics.
