An Experimental and Theoretical Study of the Adsorption and Swelling Isotherms of Human Hair in Water Vapor

Abstract

Quantitative data on the length and diameter changes accompanying the adsorption of water by human hair are given as functions of the relative humidity. Data are also given on the effects of a load on the swelling isotherms. A theoretical treatment is proposed which accounts in a semi-quantitative way for the swelling isotherms and the effects of tension as well as for the adsorption isotherm.
