1. A laminate for heating or warming, comprising:
- (a) a first outer layer of an inextensible material defining an inner surface and an outer surface opposite the inner surface;
(b) a second outer layer of an inextensible material defining an inner surface and an outer surface opposite the inner surface, wherein at least one of the first and second outer layers defines one or more predetermined punched holes therethrough;
(c) at least one heating element coextending with the first and second outer layers and interposed between inner surfaces of said first and second outer layers so as to be sandwiched therebetween, said at least one heating element being intermingled, twisted, core spun, or covered together with;
(i) at least one other heating element;
or (ii) a material having stretch and recovery properties;
(d) at least one stretch and recovery element spaced apart from, coextending and substantially parallel with the heating element and interposed between the first and second outer layers;
(e) at least one loop, formed of a portion of the at least one heating element, that extends through the one or more predetermined punched holes above a plane defined by one of said outer surfaces as said stretch and recovery element is in a relaxed or unstretched state; and
(f) an adhesive composition for bonding the heating element and stretch and recovery element as a middle layer of the laminate between the outer layers to form the laminate.

Abstract
The invention provides a laminate composite fabric which is robust, laundry-durable, and a method for forming such fabric. The laminate fabric is provided with at least one element that provides heat or warmth (heating element). Generally, the laminate fabric with heating element(s) is sufficiently robust for incorporation into garments or warming textile structures (pads and blankets). The laminate fabric may include one or more stretch and recovery elements to cause the laminate to be more adaptable for securing about any three dimensional body.

12. A method for making a laminate for warming or heating, comprising:
-
providing a length of a first piece of inextensible material having a first surface and a second surface; extending and fixing at least one length of a heating element coextensively along the length of the inextensible material, said at least one heating element being intermingled, twisted, core spun, or covered together with;
(i) at least one other heating element;
or (ii) a material having stretch and recovery properties;securing the extended length of the heating element to the first surface of said first piece of inextensible material along a substantial portion of the fixed length thereof; extending to at least 50% of its undeformed recoverable extension limit and fixing at least one length of a stretch and recovery element coextensively along the length of the first piece of inextensible material and spaced apart from and substantially parallel with the at least one length of a heating element; securing the extended length of the stretch and recovery element and the extended length of the heating element to the first surface of said first piece of inextensible material along a substantial portion of the fixed length of the first piece of inextensible material; providing a second piece of inextensible material having a first surface and second surface; securing said second piece of inextensible material either to the heating element or to the first surface of said first piece of inextensible material along a substantial portion of the length thereof coextending with said heating element to form the laminate, wherein one or both of said first piece of inextensible material and said second piece of inextensible material defines at least one punched hole therethrough; after the second piece of inextensible material is secured, relaxing the extended length of said stretch and recovery element substantially and allowing the laminate to pucker, exposing the at least one heating element through the at least one punched hole provided in at least one of the first piece of inextensible material or second piece of extensible material; and forming a loop in a portion of the at least one heating element that extends outwardly above a plane defined by the second surface of one of said pieces of inextensible material through the at least one punched hole in said one piece of inextensible material. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
