The pressure on body scars resulting from pressure garments gradually decreases with time, probably as a consequence of stress relaxation in the fabric material. In order to understand the basic mechanisms contributing to this phenomenon, an understanding of the stress relaxation behaviour of relevant textile structures is vitally important. Makes comparisons of the stress relaxation and shrinkage properties on six selected fabric samples which are all currently used by the hospitals in the UK and/or in Hong Kong. The design of the stress relaxation tests was based on the consideration of the fabric from a performance‐in‐use standpoint. The results of the tests showed differences between the fabrics collected in the UK and Hong Kong. It was also found that the stress relaxation in the wale direction was considerably lower (resulting in better performance) than in the course direction. It may be noted that the shrinkage of the fabrics was closely related to the degree of elasticity loss during washing.
