Elastic fabrics used to make pressure garments are normally cut in various sizes and different aspect ratios (i.e., width of fabric divided by gauge length). Because the aspect ratio may vary the load-strain relationships measured from the elastic fabric, the resultant pressure of a tubular elastic fabric exerted on the cylindrical surface may vary. This study investigates the effect of aspect ratio of a tubular elastic fabric on pressure changes in making up pressure garments. Both the theoretical analysis and experimental study are presented, and results from both are in close agreement.
