A flexible insulation material may be configured to substantially reduce the amount of radiation transmitted therethrough by incorporating a reflective mat of high temperature fibers that withstand temperatures of at least 500° C. The flexible insulation may be stored and used over temperatures ranging from −270° C. to 5000° C. The mat may have optical properties to produce a transmittance of no more than 5% over a range of temperature from 500° C. to 5000 vC. The mat may include high temperature fibers such as carbon and/or silicon carbide and these fibers may be coupled by a binder in a non-woven fabric. The flexible insulation material may be configured in the Flexible Thermal Protection System of a deployable aerodynamic decelerator or a Hypersonic Inflatable Aerodynamic Decelerator and may be durably flexible.

The present invention provides a laminated nonwoven fabric achieving both handling properties during manufacturing and use and adherence to a skin surface at a high level particularly when used for a face mask. The laminated nonwoven fabric includes a nonwoven fabric layer (A) and a nonwoven fabric layer (B). The nonwoven fabric layer (A) is formed from a fiber A having a single fiber diameter of 50 nm or more and 800 nm or less, and the nonwoven fabric layer (B) is formed from a fiber B having a single fiber diameter of 3 μm or more and 30 μm or less. The nonwoven fabric layer (B) includes 15 to 40% by mass of a fiber B1 to all of the fibers constituting the nonwoven fabric layer (B), the fiber having tensile strength of 2.0 cN/dtex or less as measured based on JIS L 1015: 2010 8.7.2. The nonwoven fabric layer (B) Includes a fiber B2 having tensile strength exceeding 2.0 cN/dtex as measured based on JIS L 1015: 2010 8.7.2. The nonwoven fabric layer (A) is disposed as an outermost layer of at least one surface.

Textured fibrous structures, and more particularly textured fibrous structures having a plurality of deformations such that the textures fibrous structures exhibit novel surface height properties compared to known fibrous structures, and methods for making such textured fibrous structures.

The present invention is directed at fiber compositions for noise abatement and compression resistance for vehicular applications. More particularly, the fiber compositions are suitable to replace expanded polypropylene foam pads utilized in vehicular carpet applications.

A sound-absorbing article (e.g., a tufted sound-absorbing article) can comprise a backing having a thickness and a plurality of face fibers associated with the backing. Optionally, the face fibers can comprise a plurality of tufts extending through the backing. The backing can define a plurality of perforations that fully extend through the thickness of the backing and are provided in a pattern to determine an acoustic property of the sound-absorbing article. Within at least a portion of the backing, sequential perforations within the pattern of the plurality of perforations can be spaced center-to-center by between 5 mm and 100 mm.

An improved acoustic and thermal insulation batting for use, for example, between airframe ribs in aircrafts, and that is stable, lightweight, air permeable to mitigate corrosion issues as well as inherently fire resistant and sized and shaped such that there is no need for positive retention mechanisms owing to the nature of the batting which allows for a compression or friction fit in place. The batting comprises a foam insulation core over which is provided one or more barrier, facing and/or edge layers.

Nonwoven materials having at least one layer comprising high core bicomponent fibers are provided. The nonwoven materials can have multiple layers and are suitable for use in a variety of applications, including in absorbent products. The nonwoven materials can have improved resiliency and strength and can retain their structure under wetted conditions and after tension and compression.

The present invention relates to a molded body, a sandwich panel using same as a core layer, and a method for manufacturing same, the molded body having a non-woven fiber aggregate structure comprising two or more non-woven fiber aggregates. The molded body comprises a polyester-based fiber and a polypropylene composite fiber, wherein the polypropylene composite fiber comprises polypropylene and maleic anhydride polyolefin.

A side rail assembly and a mattress assembly including the side rail assembly about at least a portion of a perimeter of the mattress assembly. The side rail assembly includes a laminate structure including one or more foam layers and one or more fiber layers in a stacked arrangement. The fiber layer can be a non-woven layer.
