FIELD: textiles; paper. ^ SUBSTANCE: invention refers to heat-resisting fabrics mainly used for heat insulation. Fabric includes woven core and filling threads. Fabric surface represents alternating projections and cavities containing holes. Surface area of fabric, which is occupied with projections, is not less than 50% of total surface area. Increase in mechanical strength of fabric is reached at maintaining decreased aerotransparency of fabric surface without increase in its thickness, interweaving density and number of layers. ^ EFFECT: improving operating and economic characteristics of fabric heat insulation. |
