Abstract:
Reversible tear-off closing/opening device comprising a male part suitable to be coupled to a respective female part, said male part comprising a plurality of appendices (14) with attaching heads (14B), said female part comprising a support layer (15) and a fibrous structure (16) provided on said support layer (15) for receiving said attaching heads (14B), characterized in thatsaid fibrous structure (16) comprises - a first fibrous layer (18) provided above said support layer (15), provided with first fibers, said first layer (18) being provided with a first value of average titre of the fibers, the spaces between said first fibers defining spaces for receiving said attaching heads (14B) of the male part of the device, - a second fibrous layer (19) provided above said first fibrous layer (18), provided with second fibers, having a second value of average titre of fibers that is lower than said first value of average titre, so that the spaces between said second fibers are not dimensionally suitable to receive said attaching heads (14B), so that, when coupling said male part to said female part, said attaching heads (14B) are forced to cross said second fibrous layer (19) that is thus reversibly deformed, allowing said attaching heads (14B) to enter said first fibrous layer (18) and to be received in said receiving spaces; when said attaching heads (14B) are housed in said first layer (18), said second fibrous layer (19) returns to a substantially not-deformed status and prevents said attaching heads (14B) from exiting from said housing seats.
Abstract:
Absorbent article comprising a hydrophilic polymer foam with a substantially open cell structure for absorbing liquids, characterized by comprising one or more inorganic substances belonging to the following group: silica, silicates, aluminosilicates. Adequately, the polymer foam may be associated with an absorbent core, preferably of the type comprising superabsorbent polymers.
Abstract:
The absorbent product comprises at least one layer of bonded textile fibers (F) and, inside said layer of textile fibers, a plurality of cells formed through expansion of at least one expandable substance (S).
Abstract:
A machine (11) for producing a composite multi-ply web material (38) having a plurality of continuous plies (32, 34, 36). The machine comprises at least a first mechanical element (22) with grooves (26) and projections (28) and a first guide member (41) comprising at least a first series of guide elements (40) positioned at the level of said grooves (26) and extending at least partially therewithin.
Abstract:
Absorbent material comprising a nonwoven provided with two opposite faces, a first face intended to face the area from which the fluid to be absorbed arrives and a second opposite face, said nonwoven having a first fibrous layer defining said first face, and a second fibrous layer secured to said first layer on the opposite side with respect to said first face, defining said second face; at least a part of the fibers of said first layer being hydrophobic, so that said first layer has hydrophobic properties; at least a part of the fibers of said second layer being hydrophilic, so that said second layer has hydrophilic properties; on said nonwoven there being provided first impressions on said first face and, for each first impression, a second impression on said second face substantially centered with the respective first impression; the bottoms of said first and second impressions being heat welded together; said corresponding pairs of first and second impressions being channels for acquisition of the fluid from said first face toward said second face.
Abstract:
A method for the production of a weblike material including a flocked substrate (F) is described, in which: on at least a first side of the substrate (F) is applied an adhesive (R); on said first face are distributed flock fibers (13); the fibers are anchored to the substrate by way of the adhesive. The quantity in weight of the fibers anchored to the substrate is between 0 and 30 gr/m2; the adhesive is distributed in a non-continuous way on said first side of the substrate, to create zones with flock fibers and zones free of flock fibers;
Abstract:
The composite material comprises an elastic film (F), made of polymer material, and a coating made of flocked fibers (13) on at least one face. The fibers are fixed to the film by a layer (C) of bonding material.
Abstract:
A method is described for the manufacture of a composite absorbent material comprising the following stages: superabsorbent particles (P) are distributed on at least one first textile web (V1); said at least one textile web and said particles are impregnated with a highly water-soluble bonding agent; said bonding agent is dried and the particles are induced to adhere to said at least one textile web.
Abstract:
A method for the production of an absorbent composite material, comprising the steps of: -distributing superabsorbent particles (P) on at least one first textile web (V1); -impregnating said at least one first textile web and said particles with a binder; -drying said binder and causing adhesion of the particles to said at least one textile web.
