New method for investigating the dynamic pressure behavior of compression garment

Abstract

Purpose

The paper aims to develop a system and measuring method for investigating the dynamic pressure behavior of compression garments.

Design/methodology/approach

The dynamic pressure behavior measurement, realized by use of the self‐designed system, is a direct measuring method, which is based on a rigid hemisphere with five pressure sensors distributed on its surface. The dynamic pressure is measured over time under the process of fabric 3D deformation. The pressure distributions at the basic five sites are accepted as the measuring results. The dynamic stiffness index can be calculated from dynamic pressure profile and 3D deformation of compression garments.

Findings

The measuring system records the pressure‐time curve and pressure‐deformation curve. The dynamic pressure stiffness index expresses the change in pressure owing to the change in elongation of compression fabrics. The pressure measuring system and the index provide much information in the field of compression garment assessment.

Research limitations/implications

Another characteristic that was not mentioned but important is pressure hysteresis, which can give the information about pressure decay when fabrics undergoing repeated stretch and relaxation. The influence factors of hysteresis and its role in compression garments also requires further research.

Originality/value

To determine and characterize the dynamic pressure behavior of compression garment under 3D deformation, this study develops a measuring system and defines a new index. The measuring system can be used in scientific research institutes and factories, contribute to optimize process parameters and quality control of compression garment.
