Abstract
M. Harris and his colaborators studied the shrinkage of wool top and they state that the larger the shrinkage the larger the resilience Rs. This result is opposite to author's result obtained on carroted fur (XXXX). The contradiction may be explained from the following relations, when the systine of a modified fur is non-broken the larger the relative work of the elongation Er the larger is the Rs, and when the systine is broken as the carroted fur the larger the Er the smaller is the Rs. Therefore, the relations between Er and Rs of the generally modified and carroted are opposite, but the relations between feltability and Er of both cases showed a same tendency. Therefore the physical property of the more generally connected to feltability is the Er rather than Rs.
