Abstract
Official abstract text for this publication.
A method and apparatus for producing non-woven elements, including a body of bonded fibers in which graphene and/or graphene oxide is incorporated.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing non-woven elements, comprising: depositing loose unbound fibers on a movable surface and providing graphene and/or graphene oxide, and binding together said loose unbound fibers so as to form a structure of bound fibers in which at least the graphene and/or graphene oxide is incorporated, wherein the loose unbound fibers and granular superabsorbent polymer are deposited onto said movable surface, and wherein the graphene and/or graphene oxide is incorporated into said granular superabsorbent polymer. 2. The method of claim 1 , wherein the graphene and/or graphene oxide is deposited on said loose unbound fibers after depositing the loose unbound fibers onto said movable surface. 3. The method of claim 1 , wherein the loose unbound fibers are deposited by projecting the loose unbound fibers by pressurized air jets onto the movable surface or another surface fluidically connected to a suction source. 4. The method of claim 1 , wherein the loose unbound fibers are deposited onto said movable surface so as to form an array of blanks of discrete elements. 5. A method for producing non-woven elements, comprising: depositing loose unbound fibers on a movable surface and providing graphene and/or graphene oxide, and binding together said loose unbound fibers so as to form a structure of bound fibers in which at least the graphene and/or graphene oxide is incorporated, wherein the graphene and/or graphene oxide is coupled to said loose unbound fibers by electromagnetic fields.
