A thermal barrier configured to be rolled and unrolled while providing a thermal value of greater than about R=3. The thermal barrier comprises multiple layers including a first layer comprising a fiber mesh core and material selected from the group comprising: polyurethane, rubber, and polyvinylchloride, a second layer bonded to the first layer, the second layer comprising material selected from the group comprising: polyolefin foam, polyurethane foam and rubber based foam, and a third layer bonded to the second layer, the third layer comprising a thin film or fabric material selected from the group comprising: polyester, polyolefin, polyurethane and nylon, wherein the composite material maintains a consistent linear dimension within about 1% of total length in a coiled configuration compared with a linear configuration.

A method of forming a sloped roof can comprise obtaining a base layer comprising at least one of a permeable mesh, woven fabric, non-woven fabric, plastic, foam material or combinations thereof; applying the base layer over a roofing substrate of the sloped roof; and applying a liquid roofing material to the base layer to form a liquid applied roof.

A fibrous material or composite including a plurality of layers joined to one another, for example, by needlepunching, is disclosed. The fibrous composite generally has an asymmetrical stretch profile, such that the fibrous composite is more extensible in the cross-machine direction than in the machine direction. The fibrous composite may find particular use in forming a cure-in-place pipe liner.

Aspects herein are directed to a composite textile having a substrate layer (e.g., knit, woven, nonwoven, etc.) and a film layer that is secured or bonded to the substrate layer. A plurality of slits extend through both the substrate layer and the film layer. The film layer is formed of a material that dimensionally transforms when exposed to an external stimulus such as moisture. When exposed to moisture the film layer swells, which causes flaps formed by the plurality of slits to extend in a z-direction away from the film layer. The opening of the flaps creates through-passages that extend through the thickness of the composite structure.

The present disclosure relates to an innovative leather and a manufacturing method thereof. The innovative leather includes a TPU substrate, a TPU adhering layer, and a TPU surface layer. The TPU adhering layer is disposed on the TPU substrate. The TPU surface layer is disposed on the TPU adhering layer. All materials of the innovative leather of the present disclosure are the same TPU materials, thus the innovative leather of the present disclosure can be recycled after the innovative leather of the present disclosure is used. The innovative leather of the present disclosure has recycling benefit.

A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.

A flooring assembly (10) comprising at least one vertically lapped fibrous material layer (14), at least one pressure sensitive adhesive layer (12a) including a flexible substrate (12b), a mesh (12c) and an adhesive (12d) located along the flexible substrate, and at least one moisture impermeable membrane layer (16).

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

Load-bearing apparatus/systems for location in the vicinity of energized power lines are provided. The apparatus includes a base member. The base member has an upper layer and a backing surface layer. An uppermost surface of the upper layer is adapted to support on it at least power line workers and/or related stringing equipment. At least the uppermost surface of the upper layer is adapted to be electrically conductive. Methods for forming the apparatus are also provided.

Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights. The final composites can optionally be reintroduced into the original end use and include significant percentages of recycled material.
