Abstract

A composite interlining sheet material for garments and the like is disclosed. The composite interlining sheet material comprises a substantially continuous internal layer of porous material having low heat conductivity and high resilience. The internal layer is of a substantially uniform thickness and consistency, and its composition and thickness is such that it is supple and drapable. A continuous layer of flexible reflective material is bonded to the outside of the internal layer at at least spaced intervals and functions to reduce the conduction of heat away from the internal layer and decrease the emissivity of the composite sheet, the outside being the side which is to be disposed away from the body of the wearer or person when used as a interlining of a garment or the like when it is desired to maximize heat retention.

Claims

1. A heat insulating garment and the like for maximizing heat retention, comprising:

an outer fabric shell adapted to be disposed to cover a portion of the body of a wearer;

a composite interlining sheet material for said fabric shell, said composite interlining sheet material including (i) a substantially continuous internal layer of porous material having a low heat conductivity and high resiliency, said internal layer being of a substantially uniform thickness and consistency and having a composition and thickness such that it is supple and drapable, and said internal layer having first and second surfaces, and (ii) a continuous layer of flexible reflective material adhered to said first surface of said internal layer at at least spaced intervals, said reflective material providing a reflective surface facing away from said first surface of said internal layer to decrease the emissivity of said composite sheet material and reduce the conduction of heat in a direction away from said second surface of said internal layer toward said first surface of said internal layer; and

said composite interlining sheet material being disposed relative to said outer fabric shell in a manner (i) such that said continuous layer of reflective material faces and outer fabric shell and is between said outer fabric shell and said internal layer and (ii) such that the surface of said interlining sheet material facing said outer fabric shell is not bonded in complete physical contact with said outer fabric shell, whereby said continuous layer of reflective material will be disposed to face away from the body of the wearer when said outer fabric shell is disposed to cover a portion of the body of a wearer to thereby maximize heat retention.

2. The garment and the like of claim 1 wherein said continuous layer of reflective material includes an outer layer of flexible transparent material and an inner layer of reflective material so that said transparent material protects said reflective material.

3. The garment and the like of claim 2 wherein said outer layer of transparent material comprises a clear plastic film, and wherein said inner layer of reflective material comprises a metallized layer of reflective material deposited on said clear plastic film, said clear plastic film with said metallized layer deposited thereon being adhered at at least spaced intervals to said first surface of said internal layer so that said metallized layer is between said clear plastic film and said first surface of said internal layer.

4. The garment and the like of claim 1, further including an inner layer covering said second surface of said internal layer and being adhered to said second surface of said internal layer at at least spaced intervals.

5. The garment and the like of claim 4 wherein said inner layer is embossed to reduce laminar air flow therealong.

6. The garment and the like of claim 4 wherein said layers are adhered to one another by adhesive at spaced intervals to increase suppleness.

7. The garment and the like of claim 1 wherein said internal layer comprises a synthetic foam material.

8. The garment and the like of claim 7 wherein said synthetic foam material comprises polyurethane foam material.

9. The garment and the like of claim 1 wherein said internal layer of porous material is continuous over at least 80 percent of the area of said interlining material.

10. The the garment and the like of claim 9 wherein said internal layer is continuous over at least 90 percent of the area of said interlining material.

11. The garment and the like of claim 10 wherein said internal layer of porous material is continuous over the entire area of said composite sheet material.

12. The garment and the like of claim 1 wherein said layers are perforated to increase porosity and breathability.

13. The garment and the like of claim 1 wherein said composite sheet material has a thickness of no greater than approximately 1/8 inch.

14. The garment and the like of claim 1 further including spacer means on the surface of said continuous layer of reflective material facing away from said internal layer to reduce physical contact between said continuous layer of reflective material and said fabric shell of said garment and the like.

15. The garment and the like of claim 1, further including spacer means interposed between said continuous layer of reflective material facing away from said internal layer and said fabric shell of said garment and the like.

16. The garment and the like of claim 15 wherein said spacer means comprises embossed surfaces on said composite interlining material.

17. The garment and the like of claim 15, wherein said spacer means comprises a separate membrane of low heat conductivity interposed between said continuous layer of flexible reflective material and said fabric shell.
