Patent number: 8137088Abstract: The invention relates to a device for depositing synthetic fibers to form a non-woven web. The fibers are transported through a take-off nozzle by means of an air stream in the direction of a depositing belt. The device is provided with a guide duct for guiding fibers from the take-off nozzle to the depositing belt, said duct having a mobile retaining flap on one end of a longitudinal side that faces the depositing belt. To obtain a depositing area on the depositing belt that is separate from the environment as the position of the retaining flap is modified, the retaining flap is formed by a support and an elastic sealing lip, which is held in frictional contact with the depositing belt.Type: GrantFiled: September 23, 2005Date of Patent: March 20, 2012Assignee: Oerlikon Textile GmbH & Co. KGInventors: Galliano Boscolo, Hans-Holger Heesch

Publication number: 20100324515Abstract: The pre-consolidated spunbonded web (A) comprises continuous microfilaments having a diameter (D1) less or equal to 15 ?m, and bonding dots having a density higher than or equal to 90 dots/cm2, and more preferably higher than or equal to 100 dots/cm2. This pre-consolidated spunbonded web (A) is used preferably for making composite nonwoven, more especially hydroentangled composite nonwoven (AJBfC) comprising said pre-consolidated spunbonded web (A), and an absorbent pulp layer (P), and a carded or spunbonded cover layer (C).Type: ApplicationFiled: February 18, 2008Publication date: December 23, 2010Applicant: ALBIS SPAInventor: Galliano Boscolo

Publication number: 20090264038Abstract: The spunbonded nonwoven (W) has high elastic recovery properties and comprises a plurality of multi-component filaments. Each filament, preferably of the sheath/core type, comprises at least a first polymeric component and a second polymeric component. The first polymeric component comprises thermoplastic polyurethane, and the second polymeric component comprises an elastic propylene-based olefin copolymer, and more particularly an ethylene propylene copolymer, preferably comprising at least 80 wt % of propylene units. Said spunbonded nonwoven (W) can be easily thermal-bonded with polyolefin-based nonwoven layer(s), especially polypropylene-based layer(s), in order to make a composite nonwoven, particularly suitable for the hygienic industry (diapers, . . . ).Type: ApplicationFiled: August 6, 2007Publication date: October 22, 2009Applicant: ALBIS SPAInventors: Galliano Boscolo, Antonino Maltese

Publication number: 20090068912Abstract: The elastic spunbonded nonwoven has high elastic recovery properties and includes a plurality of multicomponent filaments. Each multicomponent filament, preferably of the sheath/core type, includes a first polymeric component extending along the length of the filament in at least a first section of the filament, and a second polymeric component extending along the length of the filament in at least a second section of the filament that is distinct from the first section. The first polymeric component comprises an elastic propylene-based olefin copolymer, and the second polymeric component comprises an elastic propylene-based olefin and has a melt flow rate that is higher than the melt flow rate of the first polymeric component. The elastic propylene-based olefin copolymer for the first polymeric component and for the second polymeric component includes propylene and from 10 to 25 weight % of one or more C2 and/or C4 to C10 alpha-olefin co-monomers.Type: ApplicationFiled: September 9, 2008Publication date: March 12, 2009Applicant: ALBIS SpaInventors: Galliano Boscolo, Antonino Maltese

Patent number: 7494947Abstract: The polypropylene-based thermoplastic fibers are uniform in cross-section, not having any degraded surface skin, and they are heat-weldable at a pressure at a temperature which is lower than the melting temperature, by virtue of internal heating due to the effect of said pressure. They are made of a first constituent with high crystallinity and at least one second constituent, compatible with the first constituent, and of crystallinity that is lower than that of the first constituent. They have a quantity of primary oxidation inhibitor lying in the range 350 ppm to 1000 ppm. Such fibers are made by spinning under conditions that avoid molecular degradation by thermal oxidation at the periphery of the fibers, in particular with cooling that is rapid immediately on leaving the extrusion head. The non-woven fabric obtained by heat-bonding such fibers is characterized by weld points that are in the form of a polymer laminate that is uniform and transparent.Type: GrantFiled: November 5, 2002Date of Patent: February 24, 2009Assignee: ALBISInventor: Galliano Boscolo

Publication number: 20060201305Abstract: To produce at least one perforation in a non-woven sheet of fibers or filaments, the sheet is brought into contact with a perforated cylinder, equipped with at least one insert. Each insert includes, at one end, a plane surface, and is provided with a recess which emerges in the plane surface, and which has a sharp edge formed by the intersection of the inner surface of the recess with the plane surface. A perforation in the non-woven sheet is obtained by cutting out a portion of the non-woven sheet by shearing of the fibers or filaments of the non-woven sheet, between the sharp edge of the insert and a perforating member driven simultaneously in translation and in rotation about its own axis.Type: ApplicationFiled: May 16, 2006Publication date: September 14, 2006Inventor: Galliano Boscolo
