FIELD: textiles; paper. ^ SUBSTANCE: invention refers to heat-resisting fabrics mainly used for heat insulation. Fabric includes woven core and filling threads. Core threads are subject to destructive impact and capable of partial separation and felting of separate fibres from thread surface at transport, erection and operation impacts on fabric. Filling threads are equipped with separated fibre parts formed during production of threads. Increase in mechanical strength of fabric is reached at maintaining decreased aerotransparency of fabric without increase in its thickness and density of interweaving. ^ EFFECT: improving operating and economic characteristics of fabric heat insulation.
