Abstract: The invention relates to a new process for the manufacturing of chitin derivatives, in particular of nanofibrillary chitin, sustainable from the industrial implementation point of view and suitable to produce chitin derivatives having improved properties. The invention further relates to chitin derivatives obtainable with such method. The invention further relates to the uses of such derivatives which comprise for example the formulation of pastes and aqueous gels useful for the topic applications on skin, the manufacturing of materials of biomedical interest, as well as the deposition of chitin nanofibrils on coating surfaces or the incorporation of the same inside articles such as, for example, hygiene sanitary products.

Abstract: An apparatus for making a multilayer absorbent element apt to be incorporated in a sanitary article is provided. The apparatus has an embossing roller bearing a plurality of protruding elements, a pierced roller bearing a plurality of protruding elements and cavities, and a unit of cohesion and drilling. The configuration of the apparatus is such that, after a first layer of sheet material is deformed by the embossing roll and the perforated roller continues to slide on the pierced roller, a second layer of sheet material is superimposed. The first and second layer of sheet material are then carried to the joining and piercing unit in which, at the intermediate zones of the first layer, it forms a plurality of holes passing through the first and second layer and joins them near or at the plurality of holes.

Abstract: An apparatus for manufacturing an absorbent element for sanitary products and a method for manufacturing the same are disclosed. The absorbent element is of the type incorporating plurality of sacs or pockets in which expandable super-absorbent material is placed.

Abstract: A machine utilized for producing and manufacturing a film, soft at touch, resilient and suitable at draining use. A film produced by such a machine, presents, at least, on one surface an essentially continuous pattern of micro-funnels three-dimensional (3D) directed in an essentially perpendicular way to the surface from which the micro-openings have origin. It presents also on the opposite surface a continuous pattern, composed by 3D macro-funnels directed in an essentially perpendicular way to the surface from which the macro-funnels have origin. The “micro-funnels” term, intend to describe a multitude of funnels non distinguishable by the human eye at a distance equal or higher than 450 mm. while the “macro funnels” term, intend to describe funnels clearly visible by the human eye at a distance higher than 450 mm.
