Flame resistant yarns and fabrics including partially aroma tic polyamide fiber and other flame resistant fibers

Abstract

The present invention provide an article exhibiting flame resistant or flame retardant property comprising fiber and yam which are made with partially aromatic polyamides and a fiber having vapor phase action such as an flame resistant cellulosic fiber. The fabric made from such fiber and yam demonstrates superior flame retardancy over traditional flame retardant nylon 6, 6 fabrics. The present invention further provides, the fiber and yam when blended with other flame retardant fiber then it does not demonstrate the dangerous "scaffolding effect", whereas, this effect is common with flame retardant nylon 6, 6 blended fabrics.
