Abstract:
1. A method for producing a latent elastic laminate material, comprising: stretching at least one elastic member; extruding a latent polymer in the form of a film or filaments; applying the latent polymer onto the at least one stretched elastic member, wherein the latent polymer is applied onto the at least one stretched elastic member at a temperature below its softening point; applying an adhesive to at least one substrate, the at least one elastic member, the latent polymer or combinations thereof; attaching at least one substrate to the latent polymer on the at least one stretched elastic member, wherein the temperature of the adhesive is below the softening point of the latent polymer upon attachment of the at least one substrate; wherein the amount of latent polymer applied to the at least one stretched elastic member provides enough force to overcome a retractive force of the at least one elastic member when the polymer is at a temperature below a softening point of the polymer, and the amount of polymer is small enough to allow the laminate to retract into an elastic, gathered structure when the laminate is heated to at least a softening point of the polymer.
