Abstract RU 2720941 C2

FIELD: protective devices.

SUBSTANCE: invention relates to use of material containing fibers which prevent oxygen penetration, which contain natural cellulose and dialcoholic cellulose. Invention also relates to a material comprising said fibers and having a density of at least 1200 kg/m³, which comprise natural cellulose and dialcoholic cellulose, wherein the oxygen permeability for the material according to ASTM D3985 is less than 30 ml⋅mcm/(m²·kPa·24 h) at 23 °C and 80 % relative humidity.

EFFECT: antioxidant protection based on modified cellulose fibers is proposed.
