Benefits of technology

The present invention provides a new stretchable composite thermal insulation material that addresses the limitations of prior art. The material is made by lining a stretchable fabric with a stretchable batting, which results in a composite material that is both stretchable and provides thermal insulation. The material can be used in articles of clothing and can be held together with a fabric using means that allow the material to stretch along first and second axes. The technical effect of this invention is to provide a more comfortable and flexible material that can better insulate against heat and cold.

Problems solved by technology

While offering added comfort to the wearer, they have very limited or poor thermal insulation properties.
On the other hand, thermal insulated garments, such as Winter coats, have been heretofore fabricated with non-stretchable insulation batting materials and as such they do not offer stretchability.

Embodiment Construction

[0016] Referring now to FIGS. 1 to 3, there is shown a preferred embodiment of a stretchable composite thermal insulation material 10 suited for use in cold weather garments, sleeping bags, horse blankets and the like. This is not intended to constitute an exhaustive list of the potential applications of the present invention.

[0017] The composite material 10 generally comprises a stretchable fibrous insulator 12 and a stretchable substrate 14. The insulator 12 and the substrate 14 are preferably at least 5% stretch. As will be seen hereinafter, the stretchable insulator 12 and the stretchable substrate 14 are secured together such that the stretchability of both materials is preserved in the assembled product, thereby allowing for the fabrication of stretchable thermally insulated products, such as cold weather jackets and sleeping bags.

[0018] The substrate 14 is preferably provided in the form of a stretchable woven fabric of synthetic yarns, such as polyester. Depending on the i...

Abstract

A stretchable composite material comprises a stretchable substrate, and stretchable continuous filament fiber insulation. The stretchable substrate and the stretchable continuous filament fiber insulation are unified face to face so as to be jointly stretchable.

Description

RELATED APPLICATIONS [0001] This is a continuation of U.S. Provisional Patent Application No. 60 / 647,411 filed on Jan. 28, 2005.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an insulation material and, more particularly, to a stretchable composite material suited for use in the fabrication of clothing, sleeping bags, horse blankets and other thermally insulated products. [0004] 2. Description of the Prior Art [0005] Stretch garments are well known. While offering added comfort to the wearer, they have very limited or poor thermal insulation properties. On the other hand, thermal insulated garments, such as Winter coats, have been heretofore fabricated with non-stretchable insulation batting materials and as such they do not offer stretchability. [0006] There is thus a need for a new composite material that would allow for the manufacturing of clothing and other products offering both stretchability and high thermal insulation pr...
