FIELD: production of a product made out of a non-woven material with a three-dimensional stamping.
SUBSTANCE: the invention is pertaining to a product made out of product made out of a non-woven material with a three-dimensional stamping, in particular, of a flat form consisting of fibers and-or elementary filaments and having on its both sides the areas with uniformly or non-uniformly alternating elevations and the excavations and separated from each other across a direction of the material driving by non-stamping solid sections, which are drawn out in the direction of the drive of the material and occupy from 5 up to 50 % of the surface of the non-stamped non-woven material. At that the elevations arranged on one side form on the opposite side an excavations, and correspondingly the excavations arranged on one side form on the opposite side of elevations. At that the elevations located on both sides are made boldly protruding in respect to the surfaces, which are on both sides formed by imaginary prolongation of the surfaces of non-stamped solid areas. The offered invention also concerns the method of manufacture of the above-stated product and the device for its realization. The offered invention ensures production of a stamped non-woven material, which not require an additional stabilizing layer, after previous compression would return its initial form better, than the so far known versions and which due to that would be better suitable for absorption of liquids of a different composition or for transportation of the liquids into an absorption layer.
EFFECT: the invention ensures production of a stamped non-woven material not requiring an additional stabilizing layer, better than the so far known versions restoring its initial form after compression, better suitable for absorption of different liquids and for their transportation into an absorption layer.
