ABSORBING LAYER WITH SYSTEMATISED STRUCTURE OF ADHESIVE MATERIAL Russian patent published in 2014 - IPC A61F13/539 

FIELD: medicine.

SUBSTANCE: invention relates to an absorbing core for absorbing products, such as hygienic towels and similar to them, and relates to a method of production of such absorbing core. An absorbing product for women's hygiene contains an upper sheet, an back sheet and the absorbing core, placed between the upper sheet and the back sheet and which has longitudinal and transverse axes. The absorbing core is formed from: a covering layer, which has the first surface and the second surface, a layer of the first auxiliary adhesive, applied on the second surface of the covering layer, a base layer, which has the first surface and the second surface, an absorbing layer, which contains a layer of superabsorbing polymer particles and a layer of a thermoplastic adhesive; optionally, a layer of the second auxiliary adhesive, applied on the first surface of the base layer. The first surface of the covering layer and the first surface of the base layer are faced to the user in the process of the product wearing, and the second surface of the covering layer and the second surface of the covering layer are faced to the user's clothes in the process of the product wearing. The layer of the superabsorbing polymer particles is contained between the second surface of the covering layer and the first surface of the base layer. The layer of the thermoplastic adhesive covers the mentioned layer of the superabsorbing polymer particles on the first surface of the base layer, with the first auxiliary adhesive being applied in the form of a structure, which covers less than 50% and more than 15%, preferably less than 35% and more than 25% of the area of the second surface of the covering layer.

EFFECT: construction improvement.
