Abstract
The crimp rigidity test devised by the Hosiery and Allied Trades Research Asso ciation (HATRA), England is used as a measure of crimp retraction and also of the "degree of set." This paper attempts to assess how far this test is representative of set. Of the two components of crimp rigidity (extension under load and recovery upon unloading), only the recovery component is related to set in the samples studied.
