Effect of Fabric Elongation on the Making Up of Pressure Garments

Pressure garments are widely used in Hong Kong andmany other countries for burn rehabilitation.Thesegarments are mainly made of elastic Lycra fabrics andtailor-made to individual patient's measurement toprovide an appropriate amount of skin-garment in-terface pressure for medical treatment.However,thefabric tension would be reduced due to fabric elonga-tion under prolonged period of stress,and thus theskin-garment interface pressure cannot be main-tained after repeated use of the garment.This paperaims to study the behaviour of fabric elongation of thefabrics commonly used for making pressure garmentsin U.K.and/or Hong Kong.Attempts to correct theexisting practice of drafting the pressure garments forproviding a more effective clinical treatment.     

An Experimental Study of Aspect Ratio on the Tensile Properties of an Elastic Fabric for Making-up of Pressure Garments

The“cut-and-sewn” pressure garments are normally tailored made in various sizes according to the size of human body as well as the area of burn wounds.When a tubular pressure garment is cut in different length and width measurements,different aspect ratio will be occurred on the elastic fabric for making up the pressuregarment. Many therapists in Hong Kong concerned the change of aspect ratio may affect the tensile properties of the elastic fabric and ultimately will affect the skin-and-garment interface pressure for the patient.The aim of     

A STUDY OF SEAM STRENGTH AND EXTENSIBILITY FOR PRESSURE GARMENTS

Pressure garments are functional garments designed for medical purposes and arc normally used under prolonged stress. The stress across seams is related to the size of the wearer and the fit and the garment, the more close fitting a garment, the greater stress is put on the seam. Since pressure garments are subjected to appreciable stress during wear, seams with the required strength and extensiblity are particular important. The seam type, stitch type, stitch density and thread strength are the main factors determining the strength and extensibility of a seam. In this paper, investigation of seam strength and extensibility are made on four types of seams which have been used for making pressure garments. Five different types of stitch densities and two sizes of sewing thread are used on each type of scam to be tested. The seaming conditions of the selected fabric are also examined.

Effects of Compression Garments on Lower Limb Muscle Activation via Electromyography Analysis during Running

Sports compression garments are common-selected sportswear to improve athletic performance and reduce sports injury. Since they consist of elastic textile that exerts compression and pressure onto the muscle,muscle activation is of interest to sports compression garment manufactures who seek to enhance sports performance through gradient compression garment design.However,there are few scientific investigations to explore this effect of muscle activation to evaluate the performance of sports compression garments during sport activity. In this paper, a systemic experimental protocol was presented to improve the quality of evaluation test under a standardized running test. Then muscle activation with and without wearing sport compression garments to highlight the changes caused by compression garment was investigated. The electromyography( EMG) signal was collected and processed by the proposed method to represent the muscle activation combined with gait analysis of running. As a result,the average muscle activation of gait cycle for the major muscles such as rectus femoris( RF) and gastrocnemius medialis( GM) revealed that they needed to exert more muscle force without wearing garment at certain periods for mid-stand and pre-swing phase within gait cycle. These lower muscle activation levels prolonged activity duration,reduced fatigue,and presented low risk for sport injury.Such an evaluation study therefore would scientifically prove the effect of compression garment and provide information on muscle activation and the ergonomic efficacy of gradient compression garment design.
