Experimental investigation the dynamic pressure attenuation of elastic fabric for compression garment

Compression garments are made of elastic fabric, which is used for operational reasons and clinical applications for treating venous ulceration, deep vein thrombosis or burns. The constant pressure of compression garments exerted on human body is very essential, and the success of the application is extremely dependent on this pressure. However, elastic fabric has a characteristic of hysteresis which contributes to the pressure decay during wearing. In this study, dynamic pressure attenuation is investigated experimentally. Dynamic pressure decreases with the repeated extension and recovery; its pressure attenuation increases as the extension level varied from 10% to 40%. The effects of fabric parameters on dynamic pressure at 1st test cycle and on dynamic pressure attenuation are also analyzed, such as spandex feeding rate and fabric structure. These results provide a better understanding of characteristics of elastic fabric used for making compression garments, and are beneficial for practitioners with scientific developments and for effective applications.
