WOMEN HYGIENIC ABSORBENT ARTICLES COMPRISING WATER ABSORBING COMPOSITE MATERIALS Russian patent published in 2015 - IPC A61F13/15 

FIELD: personal use articles.

SUBSTANCE: invention relates to women hygienic absorbent article comprising the water absorbing composite materials obtained by foaming an aqueous mixture containing at least one monoethylene unsaturated monomer bearing acid groups, at least one crosslinking agent, at least one initiator, and at least one surfactant of contacting with the resulting foamed material with at least one web of synthetic fibres, and polymerisation, to the composite materials themselves, as well as their use for absorption of aqueous liquids.

EFFECT: improved properties of women hygienic absorbent articles containing superabsorbent foamed materials, in particular by providing foamed materials that have good absorbent, retaining and conducting properties of aqueous liquids and are stable, particularly when wet, handled effectively, processed effectively and simple in the manufacture, providing of women hygienic absorbent articles containing superabsorbent foamed materials which swell only in one dimension and that do not shrink in drying.
