Identification of the contaminants present in secondary fibers would aid in the reduction of the stickies problem common to the secondary fiber Industry. Presently, Identification and quantitative analysis of stickies is difficult. The staining characteristics of the hotmelts and latexes were studied and used to complete a flow chart analysis of a sample to determine the type and quantity of contaminants. Dupont '4 and Superlitefast Brilliant Blue dyes were shown to stain the hotmelts. Analysis of a sample through the flow chart developed for this thesis would determine the type and quantity of contaminants present. These results may be used to better determine the effectiveness of contaminant removal by different cleaning methods used in the recycle industry.
