Publication number: 20230144496Abstract: Some aspects of the present disclosure generally relates to materials such as nonwoven materials, e.g., comprising fibers. Some examples of fibers include polyester, rayon, polyethylene terephthalate, polyvinyl acetate, etc. In some embodiments, the material may be functionalized in some manner. For example, a hydrophilic polymer such as polyethylene oxide may be bonded to at least some of the fibers and/or to itself. In some cases, the hydrophilic polymer may be substantially uniformly bonded to the fibers. In some cases, the functionalized material may be relatively permeable, which may allow fluids to flow therethrough. For example, the material may have a relatively high permeability to air, e.g., of at least 5 ft3/min/ft2. Other aspects are generally directed to methods of making or using such materials, kits including such materials, etc.Type: ApplicationFiled: March 31, 2021Publication date: May 11, 2023Applicant: National Nonwovens Inc.Inventors: Conrad Anthony D'Elia, Mark Gregory Lawrence, Karen Spaulding Hawks

Patent number: 10549498Abstract: The present invention generally relates to composites and articles made from nonwoven structures. One aspect of the invention is generally directed to nonwoven structures which are heated and/or pressed to form a substantially rigid article. In some cases, the nonwoven structure may be heated to temperatures greater than the glass transition temperature but less than the melting temperature of a polymer within the nonwoven structure. Such articles may exhibit creep of the polymer around other fibers in the nonwoven structure, but without any evidence of melting and/or flow. In addition, in some embodiments, such articles may have relatively large void volumes, or exhibit properties such as low flammability, smoke resistance, or acoustic insulation. Other aspects of the present invention are generally directed to systems and methods for making such articles, methods of use of such articles, kits comprising such articles, etc.Type: GrantFiled: March 9, 2016Date of Patent: February 4, 2020Assignee: National Nonwovens Inc.Inventors: Mark Gregory Lawrence, Conrad Anthony D'Elia, Anthony Joseph Centofanti, Paul Anthony Viveiros

Patent number: 10549501Abstract: The present invention generally relates to nonwoven structures and composites comprising such nonwoven structures, particularly structures incorporating foam, and methods of making and use thereof. One aspect of the invention is generally directed to composites comprising a nonwoven structure immobilized to foam, e.g., using adhesive, needling, or other techniques. The nonwoven structure may comprise any of a variety of fibers. In certain embodiments, the composite may be substantially thermally insulating and/or acoustic insulating. Other aspects of the present invention are generally directed to systems and methods for making such composites, methods of use of such composites, kits comprising such composites, and the like.Type: GrantFiled: March 9, 2016Date of Patent: February 4, 2020Assignee: National Nonwovens Inc.Inventors: Mark Gregory Lawrence, Conrad Anthony D'Elia, Anthony Joseph Centofanti, Paul Anthony Viveiros
