Abstract

The effect of permanent press resin of the dimethylol ethelene urea (DMEU) type on 100% cotton fabric resistivity, as measured on a guarded hot plate, was studied. Increased add-on reduced average air pore size and increased solid content. A reduction in fabric thickness and an increase in actual contact area with a solid surface were also observed. A maximum of resistivity was obtained for an add-on of 4.4%. Further increase in add-on caused a reduction in resistivity as bulk density increased. These results were compared with theoretical models of heat transfer through randomly oriented fiber assemblies.
