Patent number: 7118558Abstract: An elastic assembly for absorbent garments having a first carrier layer, a second carrier layer, and an elastic layer attached between the first and second carrier layers to impart elasticity to an elasticized portion of the elastic assembly. The elastic layer is made of elastic strands having a decitex of about 600 or less. The elastic strands are arranged generally in parallel with one another and with a spacing of about 1 to about 10 elastic strands per centimeter. The elasticized portion of the elastic assembly has a thickness of about 2.6 mm or less at a pressure of 0.05 p.s.i. and about 8 or more corrugations per centimeter when in an elastically relaxed state. The first and second carrier layers are attached to one another in the elasticized portion substantially only by a coating of adhesive on the elastic strands. Absorbent garments incorporating the elastic assembly and a method of making the elastic assembly are also provided.Type: GrantFiled: September 24, 2003Date of Patent: October 10, 2006Assignee: Tyco Healthcare Retail Services AGInventors: Lanying Z. Wu, Joseph B. Vergona, Ruth L. Levy, Edward P. Erdman, Stacy J. Driskell

Patent number: 5620779Abstract: There is provided herein a ribbed clothlike nonwoven fabric made by a method comprising the steps of providing a nonwoven web of thermoplastic polymer of staple length or longer fibers or filaments having a pattern of fused bond areas wherein the pattern has at least one space and at least one unit width, as defined herein, in a ratio of at least 0.30, and then extending the web up to less than the breaking point of the fibers or filaments in at least one direction. The product which is thereby produced is a ribbed clothlike nonwoven fabric comprising a web of thermoplastic polymer of staple length or longer fibers or filaments having a pattern of fused bond areas wherein the pattern has space and unit width in a ratio of at least 0.30, and wherein the fabric has been extended up to less than the breaking point of the fibers or filaments in at least one direction so as to produce ribs.Type: GrantFiled: March 25, 1996Date of Patent: April 15, 1997Assignee: Kimberly-Clark CorporationInventors: Ruth L. Levy, Ann L. McCormack

Patent number: 5582903Abstract: Disclosed is a method of producing a barrier fabric having stretch and recovery properties. The method includes the steps of heating at least one nonwoven web containing meltblown non-elastic thermoplastic polymer fibers to a temperature at which the peak total energy absorbed by the nonwoven web of meltblown fibers is at least about 250 percent greater than the amount absorbed by the nonwoven web of meltblown fibers at room temperature; applying a tensioning force to neck the heated nonwoven web; and cooling the necked nonwoven web so that the nonwoven web has at least the same hydrostatic head and/or particulate barrier properties as the nonwoven web before necking. Also disclosed is a stretchable barrier fabric composed of a nonwoven web of meltblown non-elastomeric thermoplastic polymer fibers, the nonwoven web being heat treated so that it is adapted to stretch at least about 10 percent more than an identical untreated nonwoven web of meltblown non-elastomeric thermoplastic polymer fibers.Type: GrantFiled: November 15, 1995Date of Patent: December 10, 1996Assignee: Kimberly-Clark CorporationInventors: Ruth L. Levy, Charles E. Bolian, II, Michael T. Morman, Lynn E. Preston

Patent number: 5575874Abstract: A shaped nonwoven fabric comprises continuous spunbond filaments made by directly forming the spunbond filaments into a web in a single process. The fabric has an array of discrete surface features such as apertures or projections, or both. The spunbond filaments are bonded together with an adhesive polymeric component so that the shape of the fabric is retained. The fabric can be engineered to have particular fluid handling properties, strength properties, abrasive properties and aesthetic properties. Articles such as personal care products, garments, medical products and cleaning products are also disclosed.Type: GrantFiled: May 5, 1995Date of Patent: November 19, 1996Assignee: Kimberly-Clark CorporationInventors: Henry L. Griesbach, III, Richard D. Pike, Sharon W. Gwaltney, Ruth L. Levy, Lawrence H. Sawyer, Richard M. Shane, Philip A. Sasse
