Sealed heat insulation structure for use in e.g. potholder used in restaurant, has two layers respectively formed on faces of structure and superimposed on one another, where one of layers is made of brushed cotton

摘要

The structure has two layers respectively formed on two faces of the structure. One of the layers is made of brushed cotton, and another layer i.e. kelvar (RTM: poly paraphenylene terephthalamide) layer, is made of polymer of type brushed aramide, where the two layers are superimposed on one another. Third layer is formed on the latter layer, where the third layer is made polymer of type acrylonitrile butadiene or silicone. Thickness of the third layer ranges between 0.4 and 0.8 mm, and thickness of the latter layer ranges between 1.6 and 3.0 mm.
