Abstract
An apparatus and method for measuring characteristics of entities in a sample of textile material, including trash, provides a sample of textile material to a processor where entities are individualized and thereafter transported to a sensor system. Characteristic signals are generated by the sensor signal corresponding to sensed characteristics of the entities, including trash, and a computer analyzes the characteristic signals to identify signals corresponding to trash and to classify the trash signals as corresponding to one of several types of trash. Based on the characteristic signals, the computer determines an entity length, diameter and speed and also determines a peak value of a characteristic signal corresponding to an entity. Based on these measurements, trash is characterized as to one of several types of trash.
