  • Method of cooling an object with a fabric
    Patent number: 9121642
    Abstract: A fabric for thermal management including the cooling of an object, such as a person's skin. The fabric is formed of a plurality of materials including at least one liquid transport enhancing material and at least one evaporative transport impeding material. When the fabric is in use, the transport enhancing material is located near an object to be cooled, while the evaporation impeding material is spaced away from the object. The fabric is peached so that there is an entanglement of the two materials. Peaching is performed on both sides of the fabric, but initially on the side with the transport enhancing material such that a portion of the evaporation impeding material is pulled into the fabric core. A method of making the fabric is also described.
    Type: Grant
