By using a simple dye staining technique the distribution of a wide range of polymers can be readily seen on wool. After staining with selected dyes, samples are mounted in media with refractive indices similar to that of wool and examined using a conventional optical microscope. The different types of polymer distribution observed correlate well with scanning electron micrographs, but the technique is much simpler and easier to use than electron microscopy. It is possible to view polymers in locations that are inaccessible by other techniques. Visual examination of pieces of stained fabric enables the evenness of polymer treatments to be assessed.
