FLAME RESISTANT YARNS AND FABRICS INCLUDING PARTIALLY AROMATIC POLYAMIDE FIBER AND OTHER FLAME RESISTANT FIBERS

摘要

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.
