ABSTRACT
The following study deals with the ever present problem of waste handling. Clean reworkable waste refers to primarily sliver from piece-ups, roving bobbin strips, and pneumafil. To start, the source and amount of clean reworkable waste produced was studied at a sheeting yarn manufacturing facility. This study yielded an approximate rate and proportion at which clean reworkable waste should be added. It was found that pneumafil accounted for approximately 40% of the total waste while roving bobbin strips made-up about 25%. For the study a 37s 50/50 polyester/cotton yarn was produced using Clemson University laboratory manufacturing equipment. Separate forms of clean reworkable waste were added at 3.5% to the polyester lay down. A blend of the waste forms was added at 3.5%, 7.0% and 10.5%. Testing was performed on the Uster Evenness Tester II, Classimat, Statimat II, and Scott Tester.
