The purpose of this study was to investigate the friction characteristics of different fabrics used in personal protective equipment worn during competition and matches. During vigorous taekwondo activity, sweat, movement, and body collisions may cause personal protective equipment to slide from its original position and accordingly fail to protect the athletes effectively. Therefore, a thorough study investigating the friction characteristics among different fabrics used in personal protective equipment and its effect on the skin is needed. This study is intended to be helpful for the athletes in the selection of appropriate personal protective equipment fabrics. Universal Nano + Micro + Macro Materials Tester was used in friction tests between six different personal protective equipment fabrics and the dorsum forearm skin to obtain the coefficients of kinetic friction and static friction. The results indicated that PVC faux leather showed better anti-skid performance under dry conditions. Under wet conditions, however, the friction coefficient of PVC faux leather decreased significantly due to lubrication, and thus lowered the anti-skid performance. In addition, the friction coefficient of fabrics with better water absorption or drainage capacity showed greater adhesion with the increasing of skin hydration. In particular, 100% polyester weft-knitted fabric showed better anti-skid performance under wet conditions. The result of this study provides a good reference in the selection and design of Taekwondo personal protective equipment for athletes, coaches, and manufacturers. |
