Abstract: The invention provides a substrate for inhibiting heat transfer. The substrate includes a textile base layer formed with filamentary members. The substrate also includes a sliver layer having a plurality of staple fibers interlaced with the filamentary members of the textile base layer. The staple fibers of the sliver layer are oriented substantially perpendicular to the base layer. The substrate also includes at least one reflective layer attached to one of the base layer and the sliver layer.

Abstract: The invention provides a substrate. The substrate includes a plurality of first filamentary members oriented in a first direction. The first filamentary members are arranged in spaced apart relation to one another. The substrate also includes a plurality of second filamentary members oriented in a second direction transverse to the first direction. The second filamentary members are spaced apart from one another. The second filamentary members are interlaced with the first filamentary members to define an open mesh. The substrate also includes a plurality of elongated strips of non-woven material oriented in the first direction. Each of the non-woven strips is positioned between at least two of the first filamentary members and interlaced with the second filamentary members.

Abstract: A sleeve assembly for receiving and protecting elongated items within a duct is disclosed. The sleeve assembly includes a plurality of separate and independent sleeves, each sleeve being woven from warp and weft filamentary members that form sidewalls surrounding and defining a central space. Pull cords are located within each central space for drawing the elongated items through the sleeves once positioned within a duct. The assembly includes means for drawing the sleeves simultaneously through the duct, such means including an outer jacket surrounding the sleeves, the jacket having an inwardly facing surface that exerts a compressive force on the sleeves causing them to be drawn through the duct together with the jacket. The means may also include a loop which attaches the sleeved together at one end. The sleeves may be biased into an open or a substantially flattened configuration.

Abstract: A filamentary member and a sleeve made therewith are disclosed. The filamentary member has an inner core formed of a material with a high tensile strength. The core is surrounded by an outer sheath formed of an abrasion resistant material. The filamentary member is formed by co-extruding the core and the sheath together through a spinnerette having coaxial nozzles. When spun from a molten state, the core and sheath fuse at the interface between them to provide transverse shear continuity. The sleeve may be woven, knitted or braided using the filamentary members and has the characteristics of abrasion resistance and high tensile strength without the need for separate yarns having these characteristics.
