20100018645 | Treated Nonwoven Fabrics and Window Shades Incorporating Same - A nonwoven fabric treated to provide pleat retention, static control, stain-resistance, and antimicrobial efficacy for a window shade application. The stain-resistant finish does not significantly interfere with the subsequent printing, as well as the pleating and gluing of the nonwoven fabric into a window shade. A test method to determine the degree of stain resistance to common household products is also described. | 01-28-2010 |
20100147621 | SOUND ATTENUATING ARTICLES HAVING REBULKABLE NONWOVEN WEBS AND METHODS OF FORMING SAME - A method of forming a sound attenuating material includes heating a densified, rebulkable nonwoven web at a sufficient temperature and for a sufficient time to rebulk the nonwoven web to an open, lofty form; compressing the rebulked nonwoven web to a predetermined thickness; and cooling the compressed nonwoven web at a sufficient temperature and for a sufficient time to cause the compressed nonwoven web to maintain the predetermined thickness. The cooled, compressed nonwoven web may further be formed into a desired shape. One or more additional layers of material may be laminated to the densified, rebulkable nonwoven web substantially simultaneously with the heating step. The nonwoven web may be heated to a temperature above the melt point of at least one component fiber of the nonwoven web and heating may be accomplished by heating one or both sides of the nonwoven web. | 06-17-2010 |
20100314195 | Acoustically Tunable Sound Absorption Articles and Methods of Making Same - The present invention provides a tunable sound absorption facing which includes a cellulosic web and a nonwoven web entangled together. The facing has a controllable air flow resistance. | 12-16-2010 |
20110114414 | ACOUSTICALLY TUNABLE SOUND ABSORPTION ARTICLES AND METHODS OF MAKING SAME - A moldable acoustic facing comprises cellulosic fibers and synthetic fibers entangled together. The acoustic facing has a basis weight of from about 1.5 to about 5.0 ounces per square yard (osy), a thickness of less than about 0.050″, a mean pore size of between about 8 microns and about 40 microns, and an elongation at break of at least twenty percent. The acoustic facing includes less than about five percent synthetic microfiber and has an acoustic resistance of at least about 250 Rayls. | 05-19-2011 |
20110283458 | Ticking Layers that Reduce Flame Propagation and Upholstered Articles Incorporating Same - A method of producing a ticking includes laminating a flame retardant backer to film material, wherein the backer releases flame retardant in the vapor phase that reduces the rate of flame propagation along the film material, when the ticking layer is exposed to flame. The backer is laminated in direct contact with the film material. In some embodiments, the laminated ticking is configured to release less than 15 MJ of heat in the first ten minutes when exposed to a flame in accordance with the testing protocol set forth in 16 CFR 1633. Upholstered articles, such as mattresses, mattress foundations, and articles of furniture, may incorporate the ticking layer. | 11-24-2011 |
20130022805 | Heat and Flame-Resistant Materials and Upholstered Articles Incorporating Same - A mattress, foundation, or other upholstered sleep product or article includes a core and barrier material surrounding the core. The barrier material includes flame and heat-resistant material that is configured to prevent combustion of the core when the upholstered article is impinged with a gas flame according to California Technical Bulletin 603 of the State of California Department of Consumer Affairs. The barrier material may include an intumescent material that is configured to swell and char in the presence of a flame so as to form a barrier to the flame and to heat generated by the flame. | 01-24-2013 |
20130186706 | Acoustically Tunable Sound Absorption Articles and Methods of Making Same - A moldable acoustic facing comprises cellulosic fibers and synthetic fibers entangled together. The acoustic facing has a basis weight of from about 1.5 to about 5.0 ounces per square yard (osy), a thickness of less than about 0.050″, a mean pore size of between about 8 microns and about 40 microns, and an elongation at break of at least twenty percent. The acoustic facing includes less than about five percent synthetic microfiber and has an acoustic resistance of at least about 250 Rayls. | 07-25-2013 |
20150118932 | POROUS POLYMER COATINGS - The present invention provides porous polymer coatings having adhesive and air flow resistive properties. The porous polymer coating comprises a polymeric foam having a void fraction of greater than about 15% and an air permeability greater than 3 cubic feet per minute per square foot as measured based on ASTM D737-04. | 04-30-2015 |
