Glove thermal protection system
A construction for a glove or other article of clothing for use in hazardous environments is disclosed, comprising a first layer comprising a laminate that includes an inner layer comprising a woven, nonwoven, or knit material, an intermediate layer comprising a barrier to the passage therethrough of liquids that overlies the inner layer, and a thermal layer affixed to and overlying the intermediate layer in at least a portion of a bridge area. The thermal layer is approximately 0.30 mm thick. The construction also includes a second layer attached to and overlying the first layer to form an outer portion for the glove or other article of clothing. The first layer and the second layer combined provides a thermal protection performance (TPP) of at least approximately 75% greater than a reference combination of the first and the second layer that does not include the thermal layer.
