Composite based on hemp fabric with an aerogel layer, intended in particular for the palm portion of a protective glove, and a method for manufacturing the composite

Abstract

The subject of the application is a composite based on hemp fabric with an aerogel layer intended especially for the palm part of a protective glove, which is characterized in that it consists of an aerogel layer, with a thickness of 2 mm to 4 mm, saturated with poly(chloro-p-xylylene), in the form of granulate with a particle size range of 0.1 - 0.7 mm, thermal conductivity of 0.012 W / m*K at a temperature of 25°C, which aerogel layer is located between two hemp fabrics, also saturated with poly(chloro-p-xylylene), wherein the hemp fabrics constitute a fabric with a surface mass of 180.00 - 210.00 g / m2, thickness of 0.48 - 0.60 mm and a rep weave, furthermore, on the outer surface of the hemp fabric there is a poly(chloro-p-xylylene) coating with a thickness of 8 to 15 µm, on which by applying An 8 to 12 µm thick aluminum layer is deposited using magnetron sputtering techniques. The application also covers a method for producing the above composite.
