1. Hygienic product comprising an odor control material having a longitudinal direction, a transverse direction and a thickness direction, said hygienic product comprising a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core enclosed between the top sheet and the back sheet, wherein: the odor control material is located between the topsheet and the absorbent core and comprises a first carrier material wherein a plurality of odor control particles consisting of activated carbon are bonded to at least one surface of the first carrier material by a binder substance,the first carrier material in an unexpanded condition has a plurality of transversal slits, and the first carrier material in an expanded condition in the longitudinal direction has a plurality of openings, andthe first carrier material is fixed in the expanded condition in the hygienic product whereby the odor control material is in the form of a reticulated structure,wherein the hygienic product is an absorbent product,wherein the odor control material comprises a second carrier material laminated to the first carrier material in expanded condition so that the first carrier material is fixed to the second carrier material in expanded condition in the form of a reticulated structure with openings,wherein the second carrier material is a nonwoven material. 2. Hygienic product according to claim 1, wherein the odor control material is fixed in the expanded condition in the hygienic product so that the odor control material covers 5-100% of the total surface area in a horizontal plane of the hygienic product. 3. Hygienic product according to claim 1, wherein the odor control material is fixed in the expanded condition in the hygienic product so that the odor control material covers 5-60% of the total surface area in a horizontal plane of the hygienic product. 4. Hygienic product according to claim 1, wherein the first carrier material is a foam material. 5. Hygienic product according to claim 1, wherein the slits are provided in staggered rows extending in the transverse direction, having a slit length A of 5-20 mm and a slit distance B between the ends of two mutually sequential slits in the staggered row of 0.4-0.6 times the slit length A, and a row distance C between two adjacent rows of 0.4-0.6 times the slit length A. 6. Hygienic product according to claim 5, wherein the slit length A divided with the row distance C is less or equal to 10. 7. Hygienic product according to claim 1, wherein the odor control material also comprises an additive selected from the group of a plasticizer, stabilizer, agent improving dispersibility, pH regulating agent, antimicrobial substance, perfume, surfactant, and scenting substance. 8. Hygienic product according to claim 1, wherein the binder substance is water soluble so it at least partially dissolves when in contact with an aqueous solution. 9. Hygienic product according to claim 1, wherein the first carrier material has a first surface and a second opposite surface wherein the first surface is facing the liquid permeable topsheet and the second surface is facing the absorbent core wherein the odor control particles are bonded to the second surface of the first carrier material so that the surface bonded with odor control particles is facing the absorbent core. 10. Hygienic product according to claim 1, wherein the second carrier material is facing the topsheet and the first carrier material is facing the absorbent core. 11. Method for producing a hygienic product comprising an odor control material having a longitudinal direction, a transverse direction and a thickness direction, said hygienic product comprising a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core enclosed between the top sheet and the back sheet, wherein the method comprises the following steps: locating the odor control material between the topsheet and the absorbent core;providing a first carrier material forming part of the odor control material and having a first surface and a second opposite surface;bonding a plurality of odor control particles consisting of activated carbon to at least the first surface by means of a binder substance;providing a plurality of transversal slits in the first carrier material, in an unexpanded condition thereof, so that the first carrier material in an expanded condition in the longitudinal direction has a plurality of openings; andfixing the first carrier material in the expanded condition in the hygienic product whereby the odor control material is in the form of a reticulated structure,wherein the hygienic product is an absorbent product,wherein the odor control material comprises a second carrier material laminated to the first carrier material in expanded condition so that the first carrier material is fixed to the second carrier material in expanded condition in the form of a reticulated structure with openings,wherein the second carrier material is a nonwoven material.
