Insulating clothing with moisture vapor transfer and heat-reflecting elements
The granted patent US11993871B2 describes an innovative insulating material designed for use in clothing, characterized by its unique construction and properties. The material features a base layer with a moisture vapor transfer rate (MVTR) of at least 2000 g/m²/24 h, ensuring effective moisture management. Coupled to one side of this base material are heat-reflecting elements that are strategically positioned to direct heat back towards the wearer, enhancing thermal comfort. Additionally, a foam-based spacer material is integrated, which serves as the innermost layer facing the wearer. This spacer material can be made from various polymers, including polyacrylate, polyurethane, or polyolefin, and may include a crosslinking agent to improve its structural integrity.
The design of the insulating material includes a rippled profile on both the top and bottom surfaces of the base material, which contributes to the formation of cavities that can further enhance insulation. The foam-based spacer material can take on various patterns, such as line-shaped, cross-shaped, circular, or hexagonal, and can be configured as an array of discrete elements. The thickness of the spacer material can vary, with specific claims indicating thicknesses of approximately 0.1 mm or 6 mm. This innovative construction not only improves heat retention but also positions the insulating material as a valuable component in clothing articles, potentially offering enhanced comfort and performance for the wearer.
