Determination of the depth of penetration of polymeric binding in textile material in the formation of layered composites

Theoretical and experimental studies of the processes of impregnation of textile materials with polymeric binders during the formation of layered composite materials were carried out. Mathematical models have been obtained that allow determining the thickness of the polymer binder on the surface of a textile fabric when joined to the base fabric under the action of pressure rolls. As a result of experimental studies, it was found that for layered textile materials with a top layer of woven fabric the optimum value of the polymer binder film thickness is 0,03-0,06*10-3m. Also, experimentally obtained values of the effective pore radius into which the polymer binder penetrates for textile materials used in the formation of layered (composite) textile materials, is in the range of 20-100 microns.
