| 20110045261 | LAMINATE NON-WOVEN SHEET WITH HIGH-STRENGTH, MELT-BLOWN FIBER EXTERIOR LAYERS - A laminate non-woven sheet including a first layer, a second layer, and a middle layer. In one embodiment, the first layer consists of melt-blown fibers (and no other type of fibers), the melt-blown fibers have a strength of at least about 5 gpd or more and the first layer has a thickness. The second layer consists of melt-blown fibers (and no other type of fibers), the melt-blown fibers have a strength of about 5 gpd or more and the second layer has a thickness that is substantially the same as the thickness of the first layer. The middle layer is positioned between the first and second layers. The middle layer includes a dry-laid web of cellulose fibers. The middle layer is secured to the first and second layers by at least one of a group of bonds created by fusing fibers in the first, second, and middle layers or hydroentangling the first, second, and middle layers. | 02-24-2011 |
| 20100243186 | DISPOSABLE WIPERS AND TOWELS CONTAINING 40% OR MORE POST-CONSUMER WASTE - A high utility (strong in both dry and wet states, highly absorbent, abrasion resistant, thick, and soft) disposable wiper or towel that contains 40% or more cellulose fibers from post-consumer waste and/or in excess of 50% pre and/or post consumer waste. The base sheet is produced in a wet-pressed, creped process and is post-treated using a DRC process. The final wiper or towel is a double re-creped, non-woven sheet having a first side and a second side. The non-woven sheet includes about 85% to about 90% by weight of-cellulose fibers. The cellulose fibers include about 40% to about 80% of cellulose fibers from post-consumer waste. The non-woven sheet includes at least about 10% to about 15% by weight of binder. The wiper meets EPA guidelines related to the level of PCW in wipers. | 09-30-2010 |
| 20090163102 | Non-woven webs and methods of manufacturing the same - A product including a web and a method of manufacturing such a product. The product may be for use as an industrial absorbent or a thermal or acoustic insulator and includes a web including scrap and/or recycled cellulose, the cellulose being selected from a source of post-industrial cellulose and/or a source of post-consumer cellulose, the cellulose being treated with a fire-retardant, the cellulose being dry before web formation, and opened, individuated bicomponent fibers mixed with the cellulose, at least some of the bicomponent fibers being thermally bonded to at least some of the cellulose. The method may include shredding the cellulose, declumping and sizing the cellulose, metering the cellulose into a spray booth, applying a fire retardant to the cellulose in the spray booth, if the fire retardant is a liquid, drying the cellulose, adding bicomponent fibers to the cellulose, forming a web, and heating the web in an oven. | 06-25-2009 |
| 20080258586 | DUAL-USE TOWEL PRODUCT - A towel product that has dual functions is provided. The towel product includes a series of stacked towels sandwiched between a first support plate and a second support plate. The first support plate, stacked towels, and second support plate are all encased in an outer wrapper. In some cases, the towel product serves as a stand-alone product. In other cases, the towel product serves as an insert to be placed inside of a towel-dispensing container. The first support plate aids in the product's insert functions when placed inside of a towel-dispensing container and the second support plate aids the product's stand-alone functions. | 10-23-2008 |
| 20080233381 | INDUSTRIAL ABSORBENTS AND METHODS OF MANUFACTURING THE SAME - An industrial absorbent and methods of manufacturing the same. In one embodiment, the industrial absorbent includes a first scrim made from at least one thermoplastic material; a second scrim made from at least one thermoplastic material; and a middle layer positioned between the first and second scrims. The middle layer includes a dry-laid web of fire-retardant treated cellulose and opened, individuated staple bicomponent fiber. At least some of the bicomponent fiber in the middle layer is thermally bonded to at least some of the cellulose in the middle layer, and the first and second scrims are thermally bonded to the middle layer. | 09-25-2008 |
