Publication number: 20090159860Abstract: A heat and fire resistant planar unitary shield formed of heat and flame resistant fibers and voluminous bulking fibers. The shield material has a heat and flame resistant zone with a majority of the heat and flame resistant fibers, and a voluminous bulking zone with a majority of the voluminous bulking fibers. The fibers are distributed through the shield material in an manner that the heat and flame resistant fibers collect closest to the outer surface of the shield with the heat and flame resistant zone, and the voluminous bulking fibers collect closest to the outer surface of the shield material with the voluminous bulking zone.Type: ApplicationFiled: November 25, 2008Publication date: June 25, 2009Inventors: David E. Wenstrup, Gregory J. Thompson, Jason G. Chay, Ty G. Dawson

Patent number: 7428803Abstract: A ceiling system having panels suspended from a ceiling with a frame and suspension connections. The panels are a non-woven material including first effect fibers, first binder fibers, second binder fibers, and second effect fibers. The non-woven material has a first planar zone and a second planar zone. The first planar zone includes a greater concentration of first effect fibers and first binder fibers. The second planar zone includes a greater concentration of second effect fibers and second binder fibers. The first planar zone can include a first surface skin associated with the first planar zone on the exterior of the non-woven material, and a second surface skin associated with the second planar zone on the exterior of the non-woven material.Type: GrantFiled: September 27, 2006Date of Patent: September 30, 2008Assignee: Milliken & CompanyInventors: David E.

Patent number: 7018429Abstract: The present invention relates to methods of imparting color and ultraviolet protection to synthetic yarns or substrates. More specifically, the present invention is directed to a method of solution dyeing a polymeric material during polymerization to form a base color shade, and subsequently dyeing the polymeric material by either yarn dyeing or piece dyeing. Ultraviolet protection is also provided in the solution dyeing step, by introducing an ultraviolet stabilizing agent into the polymer. The base shade may then be transformed into a useful color pallet with enhanced lightfastness properties by applying a final color shade late in the fabric formation process.Type: GrantFiled: June 2, 2000Date of Patent: March 28, 2006Assignee: Milliken & CompanyInventor: David E.

Patent number: 6875713Abstract: A composite textile includes a batting layer, a cushion layer, and a face fabric. The batting layer has high melt temperature and low melt temperature fibers. The cushion layer is needled to the batting layer. The face fabric is bonded to the cushion layer by an adhesive. The face material/cushion layer/batting layer is heat set and rolled onto a roll for use in forming composite parts. The composite textile is more readily recyclable when the batting layer, the cushion layer, the adhesive, and the face material are all formed completely from material of the same chemical nature, such as polyolefin, polyester, or the like.Type: GrantFiled: November 14, 2000Date of Patent: April 5, 2005Assignee: Milliken & CompanyInventor: David E. Wenstrup

Publication number: 20030168146Abstract: A nonwoven web having first fibers and second fibers oriented generally perpendicular to the planar direction of the web. The first fibers are standard polyester staple fibers and the second fibers are staple fibers of a blend of polyester material having a melt temperature below the material of the first fibers and above the mold temperature of a subsequent molding process.Type: ApplicationFiled: December 23, 2002Publication date: September 11, 2003Inventors: David E.

Publication number: 20030146545Abstract: A nonwoven textile formed of first fibers and second fibers. The first fibers are standard polyester staple fibers and the second fibers are staple fibers of a blend of polyester material having a melt temperature below the material of the first fibers and above the mold temperature of a subsequent molding process. The nonwoven textile has a base area and a pile area extending from the base area. The pile area is the combination of first fibers and second fibers oriented generally perpendicular to the planar direction of the textile. The base area is a knitted portion of the first fibers and the second fibers. The nonwoven textile can also include a cover area being a knitted portion of the first fibers and second fibers disposed on the pile area opposite to the base area.Type: ApplicationFiled: November 1, 2002Publication date: August 7, 2003Inventor: David E.
