Patent number: 6491777Abstract: A method for making a fluid transfer layer has steps of depositing a first non-woven layer on a support, depositing a second non-woven layer on the first layer, with the two layers having a different melting point. The two layers are then thermally bonded to one another in a heated calender nip, during which differential shrinkage occurs because of the two layers' different melting points. A micro-bulked profile results. The composite, micro-bulked web is then mechanically bulked to provide a macro-bulked profile. The resulting non-woven fabric has a high bulk, high resistance to pore structure collapse, high resistance to compression deformation, and is more economical to produce than prior art carded or bicomponent webs. An absorbent article has a porous topsheet, the fluid transfer layer of the invention underlying the topsheet, and an absorbent core.Type: GrantFiled: December 7, 1999Date of Patent: December 10, 2002Assignee: Polymer Goup, Inc.Inventors: Errette Shemmell Bevins, III, Jacqueline Willey

Patent number: 5118372Abstract: In the manufacture of a decorative sheet material to be bonded to a substrate to provide a surface having a brushed metal appearance, a light-reflective, glossy metal layer is formed on a thermoformable carrier film. A pattern of straight and parallel microscopic cracks is created in the metal layer at a temperature below Tg of the carrier film by bi-directionally bending and drawing the resulting sheet material around a straight cracking member. Thereafter, the sheet material is stretched at a temperature above Tg of the carrier film. This creates an attractive brushed metal appearance of reduced gloss.Type: GrantFiled: November 21, 1990Date of Patent: June 2, 1992Assignee: Eastman Kodak CompanyInventor: Robert G. Spahn

Patent number: 4898762Abstract: Film-backed pressure-sensitive adhesive tape that resembles conventional creped paper-backed masking tape but can be torn cleanly with the fingers, is prepared by extruding an isotactic polypropylene film, passing it through the nip between a rubber roll and a water-cooled embossed steel roll at a temperature and rate such that predominantly crystalline film is obtained. The embossed roll imparts a ridge-and-valley configuration to one surface of the film, valleys extending crosswise of the tape and having a depth greater than half the total film thickness. When the smooth face of the film is coated with pressure-sensitive adhesive, the resultant tape can be torn readily, using only the fingers, in a straight line crosswise of the tape. When subjected to a stretching force in the machine direction (at right angles to the ridges and valleys), the tape elongates uniformly without "necking down." A specific embodiment of this invention is a sterilization indicator tape made with the above described film.Type: GrantFiled: July 1, 1988Date of Patent: February 6, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventors: Josephine S. Brown, Alan J. Sipinen

Patent number: 4720415Abstract: A method of producing a composite elastic material comprises stretching an elastic web to elongate it, for example, elongating a nonwoven web of meltblown elastomeric fibers, and bonding the elongated web to at least one gatherable web, such as a spunbonded polyester fiber material, under conditions which soften at least a portion of the elastic web to form the bonded composite web of elastic material. The composite material is relaxed immediately after the bonding to prevent the elastic web from losing its ability to contract from the stretched dimensions which it assumed during the bonding step. Such immediate relaxation of the composite material after the bonding step results in the elastic web retaining its ability to contract so that, upon termination of the elongating force, the elastic web contracts to form gathers in the gatherable web.Type: GrantFiled: July 30, 1985Date of Patent: January 19, 1988Assignee: Kimberly-Clark CorporationInventors: Michael J.
