Abstract
Yarns from six widely different cottons were subjected to a resin finishing treatment. The mechanical properties of single fibers withdrawn from untreated and treated yarns were examined. The changes in resilience and rupture properties resulting from the treatment were studied in order to determine whether the different cottons responded differently to the resin treatment. It was observed that many changes in the mechanical properties were not constant for the six cottons. Changes in resilience properties could be related to the cottons' fibrillar orientation as measured by X-ray angle.
