Rhone-Poulenc and Amoco developed an improved polyamide/imide fiber called Kermel for uses in fire protective clothing. Kermel fabrics are nonflammable. Their limiting oxygen index is 32. Resistance to carbonization is good. No. carbonization occurs at 250 degrees centigrade. At 350 degrees centigrade, carbonization takes 8 minutes. Even during carbonization, Kermel fabrics retain their physical structure. Blending with other fibers achieves such properties as comfort, low shrinkage during washing, and resistance to wear, damage, chemicals, detergents, chlorine bleaches, and creasing. A wider range of colors is also possible. Kermel is in the generic class of meta-aramids produced by polycondensation of trimellitic anhydride on diisocyanatodiphenylmethane. Dope dyeing ensures a high level of fastness.
