ABSTRACT

A state-of-the-art image analysis system was used to measure the dimensional characteristics of trash particles in raw stock. Cottons with varying levels of trash and bark content were used. Measurements of the distributions of particle size (area) and particle perimeter for a number of different cottons indicate that image analysis might be useful in defining the dimensions and types of trash particles that are difficult to remove in processing and may provide a mechanism by which cleanability can be defined objectively.
