A laboratory set-up using an online vision system was designed to observe the dispersion
behavior of glass and polyester fibers. The effect of different blend ratios, agitation speed,
and dispersion time in dispersing “logs” and formation of “ropes”, was studied. Our results
indicate that there is a specific dispersion time period in which optimum fiber dispersion can
be achieved. This time was found to be shorter for glass fibers. It was observed that the
dispersion behavior of each fiber type has a profound influence on the dispersion of fiber
blends. It was also noted that there is an optimum agitation energy which allows the logs to
be dispersed while minimizing the rope formation.
