FIELD: textiles.
SUBSTANCE: invention relates to the textile industry, namely, to production of multilayer heat-insulating materials used in the production of winter footwear as an inserted warming stocking for winter footwear, for example, high boots. The multilayer heat-insulating textile material is made flexible and includes a front layer in the form of a polymer metallised film, a second layer in the form of a non-woven fabric made of chemical fibres, a third layer in the form of a polymer metallised film, a fourth layer in the form of a non-woven camel wool fabric; the fifth layer is the foot-facing inner layer in the form of artificial fur made of camel wool, wherein the first four layers are fastened by the needle-punch method, and the fifth layer is attached to the first four layers by an adhesive method.
EFFECT: material exhibits high operating characteristics, primarily heat-protective properties, due to the increase in the heat resistance thereof and the increase in the comfort thereof on the foot of the wearer.
