The thermomechanical properties of spot-bonded nonwoven synthetic-fiber materials with a polymer binder have been investigated. The materials are composed of heterogeneous fibers, with low-melting polymers (binder) forming the surface layer. The change of deformation in uniaxial tension was studied from 20 to 150° C (rate of temperature increase 1.5° C/min) as a function of the nature of the fibers and the binder, their relative proportions, and the density and weight of the material. A theoretical explanation of the observed effects is offered.
