This method determines the ability of a fabric to recover from creasing such as might occur during normal wear. It does not necessarily reflect the resistance of a fabric to wrinkling. (The effect of high relative humidities on the ability of a fabric to recover from wrinkling is important for certain applications. This method may be used for testing fabrics at different levels of a relative humidity by enclosing the apparatus in a container maintained at the required temperatures and relative humidity. In carrying out the test, the fabric specimen may be manipulated by hand through tightly fitting sleeve openings in the container.)
Attention is drawn to the fact that for some types of fabrics, the limpness, thickness and tendency to curl of the specimen may give rise to very ill-defined crease recovery angles, and therefore an unacceptable lack of precision in making measurements. Many wool and wool mixture fabrics come under this heading.
