A cleaning member includes a nonwoven structure whose shape is retained by entanglement between single fibers having a median fiber diameter of from 100 to 2000 nm. The nonwoven structure has an apparent density of from 0.05 to 0.60 g/cm.sup.3. Preferably, the cleaning member may further include a support, and the support and the nonwoven structure may be arranged in contact with one another. Preferably, the single fiber may be an electrospun fiber. A method for manufacturing a cleaning member includes: a step of performing spinning by electrospinning, and thereby forming a deposit of a single fiber; and a step of pressing the deposit, and thereby forming a nonwoven structure having an apparent density of from 0.05 to 0.60 g/cm.sup.3.

Fibrous mats composed of polymeric fibers comprising an aromatic polymer are provided. Further, articles and methods of use of the fibrous mats, including, but not limited to filters and membranes for sampling of fluid samples, are also provided.

A textile sleeve for routing and protecting an elongate member has a wall including a textile layer with an inner surface and an opposite outer surface extending lengthwise along a central longitudinal axis between opposite ends. The inner surface is configured to bound a cavity sized for receipt of the elongate member therein. The textile layer is formed of yarns interlaced with one another, wherein a least some of the yarns include multifilaments resistant to heat and/or monofilaments resistant to heat, rendering the sleeve heat-resistant. A silicone-based coating is adhered to the outer surface to provide enhanced heat-resistance, dielectric protection and impact resistance.

A textile sleeve for routing and protecting an elongate member has a wrappable wall including a textile layer having an inner surface and an opposite outer surface extending lengthwise between opposite ends and widthwise between opposite edges. The opposite edges are configured to be wrapped about a central longitudinal axis to bound a central cavity extending lengthwise along the central longitudinal axis between the opposite ends. The textile layer is formed of yarns interlaced with one another, wherein a least some of the yarns include metal wire(s). A silicone-based layer is disposed about the outer surface of the textile layer to provide enhanced heat-resistance, dielectric protection and impact resistance.

An implosion shield of ballistic fabric adapted to mount so as to surround an implosion sleeve or dead-end on a power line. The implosion shield may be wrapped or formed as an envelope or tent including one piece and folded around the implosion sleeve or dead-end and secured with fasteners. A method of installing the implosion cover may include installing an implosion sleeve or dead-end on a power line, and then installing the implosion shield around the implosion sleeve or dead-end, by wrapping the implosion shield around the implosion sleeve or dead-end, or by securing an envelope implosion shield over the implosion sleeve or dead-end, or by draping the shield over the implosion sleeve or dead-end, or by mounting the shield on a frame over the implosion sleeve or dead-end, then detonating the implosion sleeve or dead-end. The implosion shield attenuates shock, pressure and sound waves from the detonation.

A press pad for a single level or multi-level hot press, the press pad comprising: a fabric made from two intersecting thread systems, wherein threads of a first thread system are respectively formed by a core thread and a cladding, wherein the cladding is made from an elastomer material and threads of a second thread system respectively include metal or are made from metal, wherein threads of the second thread system run in an alternating pattern over and under a group of adjacent threads of the first thread system wherein the group includes at least two directly adjacent and parallel threads, wherein groups that are separated from each other by at least one thread of the first thread system run on congruent paths or on paths that are displaced relative to each other in a thread longitudinal direction.

Three-dimensionally knitted noble metal gauzes, or sections of such gauzes, for carrying out catalytic reactions of fluids are knitted in two or multiple layers and the meshes of the individual layers are connected to one another in one form by a pile thread or multiple pile threads, so that the noble metal gauze has a tertiary structure.

The present invention discloses a hollow fiber membrane material for a high-humidification hydrogen fuel cell humidifier and a preparation method and application thereof, and belongs to the technical field of fuel cell materials. The present invention provides a hollow fiber membrane material, and the preparation method includes: mixing and dissolving sulfonated polyarylene ether nitrile resin, a pore-forming agent, a modified nano-filler and a solvent for still standing; performing vacuumizing; coagulating a spinning fluid in an internal coagulant bath and an external coagulant bath; and washing and drying an obtained crude product to obtain the hollow fiber membrane material.

A webbing for use with a tiedown or sling which has overall increase strength efficiency when compared to known tiedowns or slings which use texturized yarn. The webbing contains non-texturized yarn material having reduced elongation characteristics in the core, combined with non-texturized yarn having higher elongation and improved wear characteristics on the exterior surfaces.
