Abstract
A study has been made of some single fiber properties of wool, rayon, and Vicara zein fibers at various relative humidities, and the crease recoveries of fabrics made from the same fibers have been measured under identical conditions. In general, the wool and Vicara are similar in many load-extension properties. A fair correlation was found between fabric crease recovery on the one hand, and fiber tensile and work recovery on the other hand at low and normal humidities. At high humidity, and particularly with wet fabrics, however, this relationship no longer holds. A general correlation also seems to exist between fabric crease recovery and work returned by stretched fibers during retraction from extension to 4%.
