For the carpet industry, the most relevant new component of the Clean Air Act Amendments (CAAA) is Title V. which initiates a national operating permit program for stationary air pollution sources. Stationary sources at carpet and yarn plants include boilers, heat setting and carpet backing machines, carpet and batch dyeing equipment, polypropylene fiber extruders, and other equipment. There are two principal sources of regulated emissions from heat setting and dyeing equipment--caprolactam, a chemical commonly used during the production of nylon, plastics. and other synthetic material; and the diverse group of finishing compounds and lubricants used to facilitate processing. Caprolactum is the raw material used to manufacture nylon 6 fiber. Because the chemical reaction during manufacturing is incomplete, a quantity of caprolactum remains on the finished fiber. The amount of caprolactum emitted from Suessen and Autoclave exhaust stacks during the heat setting of nylon 6 yarn is sufficient to qualify as a Major Source category under Title V of the CAAA. Various means of reducing caprolactum emissions and contamination from finishing oil products are discussed.
