FIELD: textile, paper.
SUBSTANCE: three-dimensional nonwoven cloth warmer made from a fiber mixture containing natural and polyester fibers, characterised in that the composition of a natural organic product contains - natural goose down 80%, goose feather - up to 10%, polyester hollow fiber in 10% of the composition, bonded with a colloidal binder in an amount of not more than 7% of the total weight of the fiber composition with a total fulfilment of 728.7-767.0 Fill Power.
EFFECT: increasing the moisture resistance of the complex material due to the presence of polyester fibers in its composition at a general level of elasticity, equivalent in the permissible range of variation in the elasticity of a completely natural insulator based on down and feather.
