FIELD: textile and paper.
SUBSTANCE: fluffable heat-insulating material containing natural fibres and crushed synthetic fibres or balls of fibers. Natural fibres and crushed synthetic fibres or balls of fibres separately processed water-repellent substance for imparting water-repellent capacity of fibre and the latter aerodynamically are mixed together.
EFFECT: water-repellent fibers make fraction or a large portion of fluffable heat-insulating material, therefore higher durability of the structure, as well as water repellent capability to be favourable factor during washing or washing.
