The addition of the base solution increases the pH of the process water to a range from about 8.0 to about 6.0 thereby reducing the risk of corrosion when the process water is recirculated.Type: GrantFiled: June 25, 2004Date of Patent: December 26, 2006Assignee: Johns ManvilleInventor: Michael William Luka

Patent number: 6919117Abstract: A composite nonwoven fabric comprising multiple layers of a web formed from a blended mixture of metal fibers and nonmetal fibers is provided. The metal fibers preferably have a rough outer surface with irregular shaped cross-sections that vary along their length. The fibers of adjacent layers of the web material are interengaged in a needlepunching step. The composite nonwoven fabrics of the invention, which have very good isotropic strength. In a preferred embodiment, the composite nonwoven fabric is employed as a floor buffing pad for use with an electric floor buffing apparatus.Type: GrantFiled: July 15, 2002Date of Patent: July 19, 2005Assignee: Global Material Technologies, IncorporatedInventors: Terrence P. Kane, Kurt H. Schild, III

Patent number: 6896669Abstract: A composite absorbent member containing layers that have a controlled pore size distribution is provided. For example, in some embodiments, the composite absorbent member has an inner layer and two outer layers, in which the inner layer has a higher weight percentage of pulp fibers than the outer layers and also contains smaller pores than the outer layers. In this embodiment, the resulting composite member can have a fast intake rate, less leakage, reduced rewetting, and reduced bunching and twisting.Type: GrantFiled: December 21, 2001Date of Patent: May 24, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Patsy A. Krautkramer, Maureen M. Falls, Robert John Makolin, Glory Framary Ceman, William Reeves, Garry Roland Woltman

Publication number: 20040180599Abstract: A fiber insulation product for use as, e.g., a ductliner, includes at least one textile fiber layer laminated with at least one rotary and/or flame attenuated fiber layer. The fiber laminate provides improved thermal and acoustic insulation and excellent strength, at a low production cost.Type: ApplicationFiled: September 30, 2003Publication date: September 16, 2004Applicant: CERTAINTEED CORPORATIONInventors: Alain Yang, Gary Tripp, Wayne Shaw -
Publication number: 20030194933Abstract: A glass strand mat is produced by placing a first layer of glass filaments on a moving belt. An adhesive web binder is placed over the first layer of glass filaments, and a second layer of glass filaments is placed over the adhesive web binder. The glass filaments and the adhesive web binder are captured by a second moving belt, and heat and pressure are applied. The two layers of glass filaments are bonded together into a glass mat which is then cooled and wound into a roll.Type: ApplicationFiled: April 16, 2002Publication date: October 16, 2003Applicant: H.R.
