The Contribution of Single Fibers to the Rapid Creasing of a Wool Fabric

Abstract

Mechanical properties of wool fibers, including stress relaxation, hysteresis, lateral compression, and permanent set in bending and in extension, have been related to the quality of creases formed in a wool fabric at saturation-water content under constant load and at different temperatures. Measurements of stress relaxation and hysteresis offered the most promise. In particular, an energy-loss factor L was defined. which successfully related the quality of creases obtained in acid and alkaline conditions to those obtained in water at different temperatures. The quantitative correlations ob tained did not apply to fabries treated with Benax or formaldehyde.
