Possible Identification of Specialty Fibers by Electrophoresis

sure. Wray [2] had earlier reported that increasing air pressure gave a more unstable yam, apparently because a few large loops were more stable than a larger number of small loops. It stands to reason, however, that the degree of entanglement between filaments would increase with the increase in air pressure and this should enhance the structural integrity of the yam. As the increase in air pressure increases the disorientation of the unlooped segments of the filaments in the yam, there is an overall increase in extensibility of the yam with the increase in air pressure. Thus, Wray’s method
