Influence of manufacturing parameters of knitted compression fabric on interface pressure

Abstract

The influence of various parameters, such as knitted structure, elastane percentage, elastane yarn count and stitch length, on the interface pressure generated by compression knitted garment has been studied. An experimental device has been developed to measure interface pressure by using a FlexiForce^® sensor. The obtained result shows that the pressure generated by compression garment depends on the considered parameters. It is observed that plain knitted fabric causes high pressures on leg, generating a high value of interface pressure. Moreover, the increase in elastane percentage and elastane yarn count cause an increase in interface pressure. Contrariwise, the increase in stitch length generates a decrease in interface pressure. Mathematical models based on ANOVA analysis are also developed. The validity of these models has been demonstrated using χ²-test.
