Description:
The report gives initial results of a project to determine the nature of emissions resulting from the heat setting of carpet yarn and to identify possible control options. To collect the necessary technical information, two manufacturing facilities were visited: World Carpets in Dalton, GA (a yarn and carpet manufacturing facility) and Diamond Mills in Rome, GA (a yarn spinning facility). Information on the yarn spinning and heat setting operations was gathered, the carpet manufacturing process was viewed, and (with input from the plant technical staff) opportunities were identified for preventing and/or controlling the heat setting emissions. The face fibers currently used in the processing of carpet yarn include nylon, polypropylene (olefin), polyester, and wool, with the first three accounting for all but 0. 6% of the face fibers used. The output of the carpet mills is tufted, knitted, needle punched, felt, or braided carpet. ithout specific vent stream characteristics, it is difficult to accurately assess heat set emissions and to develop emission control strategies. However, based on an initial review of the heat set systems, only two possible control strategies appear applicable: condensation and absorption. Initial data suggest that the lowest cost control alternative is the absorber.
