ORGANIC NONWOVEN INSULATION MATERIAL Russian patent published in 2020 - IPC D04H1/22 

FIELD: consumer goods industry.

SUBSTANCE: invention relates to the field of light industry, namely, to non-woven material intended for formation of a heat-insulating layer in a garment. Nonwoven organic composite for forming a heat-insulating layer of a garment comprising a mixture of flax (bleached and unbleached) fibres with density of 0.4 to 1.0 tex- 55–60 % and form-stable polyester fibres with density of 0.3–0.7 tex - 15-25 % with addition of bicomponent low-melting fibres of "core-shell" type with concentric arrangement of density from 0.2 to 0.5 tex - 15–25 %, combined into web by means of successive vertical arrangement of fibres on entire length and depth and fastening by heat treatment, providing stable structure.

EFFECT: technical result consists in possibility of its smaller thickness than known analogues at preservation of heat-insulating properties, while providing high level of moisture output and improved mechanical properties, including increased value of breaking load and elongation to break, as well as draining of electric charge and absence of accumulation of static electricity.
