A STUDY OF THE PARAMETERS MEASURED IN THE WRINKLING OF WOOL IN A FIXED-DEFORMATION TEST.

In wrinkling tests based on angular recovery from a fixed deformation, constraints imposed on the fibres by virtue of yarn or fabric construction are of secondary importance. When ageing effects have been eliminated, this results in similar wrinkle-ratings for all fabrics. Any performance differences subjectively assessed during wear arise from either fabric deformability or optical effects caused by differences in curvature. [ABSTRACT FROM AUTHOR]
