An absorbent article (2) comprising cellulose fibers (14) present at least partially in the form of granules.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules are completely present in granular form.
The absorbent article (2) according to one or more of the preceding claims, wherein the fibers used to produce the granules are fine fibers, preferably fibers with an average fiber length of 100 to 600 μm and an average fiber thickness of 10 to 50 μm.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules are obtained from α-cellulose.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules are present in the form of a mixture of granules and fibers.
The absorbent article (2) according to one or more of the preceding claims, wherein an absorbent material (22) which serves as a secondary storage (8) is arranged on the side of the liquid-impermeable layer (10) facing the wearer's body.
The absorbent article (2) according to one or more of the preceding claims, wherein at least one third of the absorbent material (20, 22) of the absorbent body (6) consists of the cellulose fibers (14) present at least partially in the form of granules.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules are coated with an agent such as dextrin which retards the uptake of liquid.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules have been rendered hydrophobic by suitable agents such as Wacker-Silicone Finish WS 60 E.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules have a water retention capacity of at least 6 g H2O/g.
The absorbent article (2) according to one or more of the preceding claims, wherein the cellulose fibers (14) present at least partially in the form of granules have a water retention capacity of 8-16 g H2O/g.
The absorbent article (2) according to one or more of the preceding claims, wherein the absorbent material (20, 22) contains at least one care substance.
The absorbent article (2) according to one or more of the preceding claims, wherein the absorbent body (6) has at least one core piece (12), in which the absorbent material (20, 22) is accommodated, where preferably the length l of the core piece (12) is less than or equal to the length L of the absorbent article, and the width b of the core piece (12) is less than or equal to the width B of the absorbent article.
