Abstract:
1. A functional stretch laminate with a substantially puckered appearance usable in a garment comprising: (a) a first outer layer of a fabric or film defining an inner surface and an outer surface opposite the inner surface; (b) a second outer layer of a fabric or film defining an inner surface and an outer surface opposite the inner surface; (c) at least one stretch and recovery element having a relaxed strand length and a stretched strand length, and when stretched to its stretched strand length co-extending along a length of the first outer layer and interposed between the inner surfaces of each of the first and second outer layers so as to be sandwiched therebetween; (d) at least one functional element having a strand length and spaced apart from, and substantially parallel or co-extending along its length with the at least one stretch and recovery element, and interposed between the inner surfaces of each of the first and second layers so as to be sandwiched therebetween in a same plane as the at least one stretch and recovery element, wherein the at least one functional element extends out of a distal end of the functional stretch laminate in a machine direction, wherein the functional element is selected from the group consisting of: insulated single and multi-stranded metallic wires, non-insulated single and multi-stranded metallic wires, metallic coated polymeric fibers, inherently conductive polymer fibers, plastic optical fiber, silica glass optical fibers, and metallic coated films; and (e) an adhesive composition for bonding the stretch and recovery element and the functional element as a middle layer of the laminate between the outer layers; wherein as the stretch and recovery element is at its relaxed length, the functional stretch laminate has its substantially puckered appearance.
