Coefficient of Friction Between Knitted Fabric and Human Skin and Its Prediction

Abstract

It is the purpose of this paper to examine how the regain influences the coefficient of friction μs(R) between fabric and human skin and to predict μs(R). Fourteen knitted fabrics for undershirt and sport shirt, which are worn next to the skin, are used as sample. Five women subjects are selected and the measurement has been made at the left anterior forearm. μs(R) is measured in four different regain of fabric. The results are as follows: 1) The regain dependence of μs(R) is shown for the different fiber type and structure of knitted fabric. 2) It is confirmed that the degree of μs(R) between the knitted fabric with any water contents from the standard condition to 100% regain and human skin can be predicted from μk which is measured by KES instrument under the standard condition. © 1988, The Japan Research Association for Textile End-Uses.
