​This presentation presents research conducted by CSIRO (Commonwealth Scientific and Industrial Research Organisation) and USDA-ARS personnel to access the potential impact that plastic contamination in a lint bale can have on the final product. In this study, a 227 kg (500 lb) bale of lint was spiked with 6 g of plastic bale wrap and processed through a commercial textile mill to determine the effect on yarn and fabric processing performance. The first portion of this talk defines the background and setup for the study. The second portion discusses the results as well as future studies based on findings.
