Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.

A spacer fabric has two textile layers and spacer yarns that transversely connect the textile layers and where the yarns forming the textile layers are composed exclusively of a nonmetallic material. In addition, at least a first portion of the spacer yarns is composed of metallic yarn, and a weight of all metallic spacer yarns is between 40 and 96% relative to the total weight of the spacer fabric.

A thermoelectric fabric may include a plurality of first threads and second threads. The first threads may be alternately formed by p-doped and n-doped thread portions and electrically conductive first thread portions and second thread portions arranged in between. The first thread portions may form a hot side of the fabric, and the second thread portions may form a cold side. The first threads may form one of warp threads or weft threads of the fabric, and the second threads may form the other of the warp threads or weft threads. On at least one of the first thread portions of at least one of the plurality of first threads, a temperature control structure with at least one temperature control element for cooling the hot side may be present.

Embodiments of the present disclosure relate to a process for making a carbon nanomaterial fiber product and/or textile product. Such products may have new and/or enhanced properties as compared to similar products and, according to the embodiments of the present disclosure, it is less expensive to make.

Provided is a porous electrode substrate capable of reducing a drop in electromotive force when used in a battery. This porous electrode substrate comprises a carbon fiber sheet wherein carbon fibers are bound by a binder. For dust of 0.3 μm or more in particle size, the dust generation amount per 1 m.sup.2 of the porous electrode substrate is 120,000/m.sup.2 or less, as determined by the following method: dust particles in a gas obtained by suctioning at 47.2 mL/s for 40 minutes using a dust collecting hood having an opening of 500 mm×100 mm while traveling the sheet at a speed of 10 m/min from a position 200 mm below the sheet are used; the number of dust particles having a diameter within a predetermined range is measured by a particle counter; and the measured value is divided by 200 m.sup.2, which is a suction area, and the resulting value is defined as a dust generation amount per 1 m.sup.2.

A flexible wire comprises a conductive core surrounded by one or more radial p-n diodes and alternating conductive and non-conductive bands along an outermost surface. Methods for producing the wire are also disclosed, as are textiles and other flexible materials comprising or consisting of such flexible wires.
