FIBROUS MATERIAL Russian patent published in 2023 - IPC D21H27/10 D21H13/24 D21H13/26 D21H21/40 C08K3/22

Abstract RU 2796113 C1

FIELD: fibrous materials.

SUBSTANCE: invention is related to obtaining fibrous materials used for the manufacture of paper for special purposes. The fibrous material for paper packaging contains cotton fibres and dyed polyamide fibres or round polyester fibres. Polyamide or polyester fibres are composite fibres containing as a filler 0.3-1.2% by weight of metal oxides TiO₂, NiO, Cu₂O, SnO₂, MoO₂. Moreover, the total number of metal oxide particles is 1.0-4.0, the ratio of the number of aggregated metal oxide particles to the number of spherical metal oxide particles is 1.0-1.1, and the ratio of the average distance between metal oxide particles to the average diameter of metal oxide particles is in the range of 1.47-11.88.

EFFECT: fibrous material in which the composite synthetic fibres are firmly held due to the increased frictional force, and the presence of metal oxide particles provides ease of detection of protective elements in the fibre.
