Publication number: 20120238979Abstract: A disposable absorbent article having a structured fibrous web, with thermally stable, hydrophilic fibers that are thermally bonded together using heat provides a base substrate that is thermally stable. The base substrate is textured via mechanical treatment to increase its thickness and optionally modified via over bonding to improve its mechanical and fluid handling properties. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications. The structured fibrous web has a bio-based content of about 10% to about 100% using ASTM D6866-10, method B.Type: ApplicationFiled: March 15, 2011Publication date: September 20, 2012Inventors: Paul Thomas Weisman, Eric Patton Weinberger, Eric Bryan Bond, Dimitris Ioannis Collias, Patti Jean Kellett

Patent number: 8231595Abstract: A stretchable laminate, a process of making a stretchable laminate and a disposable absorbent article that includes a stretchable laminate are disclosed. The stretchable laminate includes a nonwoven web and a web of elastomeric material. The nonwoven web includes two layers of spunbond multi-component fibers and one layer of meltblown fibers. The multi-component fibers include a first polymer and a second polymer having different melt temperatures. Thermo-bonds are formed at least partially through the nonwoven web. Some of the thermo-bonds can be elongated in the cross-machine direction of the nonwoven web.Type: GrantFiled: April 8, 2010Date of Patent: July 31, 2012Assignee: The Procter & Gamble CompanyInventors: Robert Haines Turner, Donald Zgoda, Walter Douglas Daniels, Jim Thomas Bader, Erika Fabiola Galvis

Patent number: 8226626Abstract: A stretchable laminate, a process of making a stretchable laminate and a disposable absorbent article that includes a stretchable laminate are disclosed. The stretchable laminate includes a nonwoven web and a web of elastomeric material. The nonwoven web includes two layers of spunbond fibers and one layer of meltblown fibers. Some of the meltblown fibers are present in the interstices formed by the spunbond fibers of one of the layers. As a result of activation of the stretchable laminate, the nonwoven web has a Residual Maximum Peak Force of at least 0.3 N/cm.Type: GrantFiled: April 8, 2010Date of Patent: July 24, 2012Assignee: The Procter & Gamble CompanyInventors: Robert Haines Turner, Donald Zgoda, Walter Douglas Daniels, Jim Thomas Bader, Erika Fabiola Galvis

Publication number: 20120179125Abstract: An absorbent article having improved softness signals is disclosed. The article may include a topsheet or a backsheet including a nonwoven web. The web may have a basis weight of 30 gsm or less, may be formed of spunlaid fibers including polyolefin and up to 5 percent by weight TiO2, and may be impressed with a pattern of bond impressions to a bond area percentage of at least 10 percent forming a pattern of bonded regions and raised regions. The web may have opacity of 42 or greater; have an average height difference between bonded regions and raised regions of at least 280 ?m; be hydroengorged; and/or have a cross-direction tensile strength of 350 gf/cm. A nonwoven web manufactured to have a suitable combination of such features exhibits an enhanced appearance of softness, soft tactile feel and satisfactory mechanical attributes, while being relatively cost effective.Type: ApplicationFiled: August 19, 2011Publication date: July 12, 2012Inventors: Kevin Ronald Kanya, W. Andrew Coslett, John C. Parsons
