Perforated functional textile structures
First Claim
1. A functional stretch laminate with a substantially puckered appearance comprising:
- (a) a first outer layer of a fabric or film perforated with one or more predetermined vias, said first layer defining an inner surface and an outer surface;
(b) a second outer layer of a fabric or film, said second layer defining an inner surface and an outer surface;
(c) at least one stretch and recovery element;
(d) at least one functional element co-extending with the stretch and recovery element sandwiched between the inner surfaces of the outer layers, wherein when the stretch and recovery element is in a relaxed or unstretched state at least one portion of said functional element loops beyond the outer surface of the first outer layer through the one or more predetermined vias in a direction substantially perpendicular to a plane defined by the outer surface of the first outer layer; and
(e) at least one adhesive composition for bonding the stretch and recovery element and the functional element between the inner surfaces of the outer layers;
wherein the substantially puckered appearance results when the stretch and recovery element is in a relaxed or unstretched state.

Abstract
The invention provides a functional stretch laminate composite puckered fabric which is robust, laundry-durable and adaptable for securing about any three dimensional body, and a method for forming such puckered fabric. The functional stretch laminate fabric is provided with at least one functional element which can conduct electricity, conduct light, provide electromagnetic fields or provide shielding from electromagnetic fields. In addition, at least one via is provided in the functional stretch laminate allowing the functional element to extend or loop outwardly from the at least one via when the laminate is in a relaxed or unstretched state. Generally, the functional stretch laminate fabric is sufficiently robust for incorporation into garments and for applications in so-called wearable electronics.
