Patent number: 8193104Abstract: The present invention is directed to a cationic polymer emulsion binder that may be combined with a cationic active ingredient and used as a non-woven binder. This combination of cationic binder and cationic active ingredient may occur as a mixture of a cationic binder and at least one cationic active ingredient, which is then applied to loose fibers to form a non-woven; or the combination may occur after a non-woven is formed using a cationic binder, and said non-woven is then contacted with a cationic active ingredient. Non-woven wipes of the invention retain far less cationic active ingredients during use, resulting in less waste and less use of the active ingredients for the same effect as wipes made with anionic or non-ionic binders.Type: GrantFiled: November 25, 2002Date of Patent: June 5, 2012Assignee: Celanese International CorporationInventors: John C.

Publication number: 20040185728Abstract: Textiles treated with hydrophobic dispersions that exhibit superior drying rates and lower spin-dry water contents are disclosed. Polytetrafluoroethylene, polyvinyl acetate, and polyvinyl acetate/acrylic copolymer dispersions are used to treat textiles, including yarns, fabrics, linens, and articles of clothing. The use of dispersions create textiles with a discontinuous treatment of discrete individual hydrophobic particles applied to the surface. The treated textiles exhibit superior drying properties at very low levels of treatment. Also provided are methods for treating textiles with hydrophobic dispersions. The incremental cost to the textile of the treatment is minimized by low levels of treatment and flexibility in application.Type: ApplicationFiled: March 21, 2003Publication date: September 23, 2004Applicant: Optimer, Inc.Inventors: John W. Moore, Christopher S. Moore

Patent number: 6177366Abstract: This invention relates to novel airbag coating compositions comprising at least two separate and distinct layers. The first layer (base coat), being in contact with the airbag surface. comprises a composition of at least one coating material which may comprise up to 30% by parts of the total amount of material in the first layer of a silicone resin which provides excellent adhesion, excellent tensile strength, and overall lower cost than standard silicone airbag coating materials. The second layer, being a coating for the first layer, provides excellent reinforcement and aging characteristics to prevent degradation of the first layer. Such a second layer (topcoat) is preferably a silicone material. This two-layer system permits excellent strength and aging properties to prevent seam combing at relatively low cost due to the inexpensive basecoat materials and the relatively low amount required for the topcoat.Type: GrantFiled: July 9, 1999Date of Patent: January 23, 2001Assignee: Milliken & CompanyInventor: Shulong Li

Patent number: 5900298Abstract: A method of directing extruded synthetic fibers toward at least one surface of a mineral fiber insulation batt, and corresponding apparatus and resulting product. In certain embodiments, a row of extrusion heads is provided for directing extruded synthetic fibers (e.g. fibers including ethyl vinyl acetate or EVA) toward a surface(s) of the batt(s) to be impregnated with same. Optionally, extrusion heads may be provided all around the batts so as to impregnate substantially all surfaces thereof with the extruded synthetic fibers. As the fibers exit the heads, they are hit with pressurized heated air streams which cause them to go into an insipid spin which increases directional tensile strength of the resulting batt in all directions. In certain embodiments, every other batt of a plurality of batts passes over an elongated member which extends over top of the conveyor in order to more efficiently impregnate edge surfaces of the batts.Type: GrantFiled: July 22, 1997Date of Patent: May 4, 1999Assignee: Guardian Fiberglass, Inc.Inventors: Robert W. Syme, Joseph T. Church, Gary E. Romes

Patent number: 5733624Abstract: A mineral fiber (e.g. fiberglass) thermal insulation batt is disclosed wherein a base mineral fiber layer is impregnated with a two-layer layering system so as to produce a batt which is substantially vapor impermeable with a perm vapor rating less than about one. The first layer of the layering system is of a low melt material while the second layer is of a high melt material, the first layer being sandwiched between the base insulating layer and the second layer, and functioning to bond the layering system to the base. In certain embodiments, the first layer includes quick blooming ethyl vinyl acetate (e.g. from about 10-25%) and a low density (e.g. 22-26 lbs. per cubic foot) polyethylene, and the second layer includes high density (e.g. 28-38 lbs. per cubic foot) polyethylene. The resulting insulation batt is vapor impermeable, less susceptible to cold-crack, easier to manufacture, a better fire retardant, more durable, and easier to handle.Type: GrantFiled: July 22, 1996Date of Patent: March 31, 1998Assignee: Guardian Fiberglass, Inc.Inventors: Robert W.
