Abstract
Disclosed are technical fibers and yams 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 yams, when blended with other flame retardant fibers, do not demonstrate the dangerous “scaffolding effect” common with flame retardant nylon 6,6 blended fabrics.
Claims28
An article exhibiting flame resistant or flame retardant property comprising a primary yarn;
- wherein said primary yarn comprises a flame resistant or flame retardant (FR) fiber having vapor phase action and a fiber different from said flame resistant or flame retardant fiber comprising a partially aromatic polyamide fiber;
- wherein said partially aromatic polyamide is spun into fiber without FR additives.
