THERMAL CONDUCTIVITY OF WET FABRICS.

Abstract

In the reported study, the thermal conductivity of wet fabrics parallel to warps (K//w) and normal to the fabric surface (K//v) were measured by a line heat source method. The results obtained when p//l, the volume fraction of water in interfiber spaces, is between 0 and 1, are as follows: (1) The relation between K//v and p//l is approximately expressed by a quadratic curve, and that between K//w and p//l by a straight line. (2) The specific heat of wet fabrics calculated by the thermal properties of their components agrees well with the experimental values. (3) For 0 less than p//l less than 1, the thermal conductivity of wet fabrics can be estimated from equations derived by the authors.
