ELECTROCHROMIC WIRE THREAD AND RELATIVE FABRICS
The present invention is directed to eyectrochromic, supercapacitor yarns and the related fabrics. An electrochromic yarn formed by two interwind threads has been invented. The yarn is electrically isolated by a transparent, uncolored polymer. Each thread is the superposition of three concentric layers. The most internal one, the core, has the function of support and/or conductive layer, the second one is the eiectrochromic layer containing conductive nanoparticies, the third layer is a polymer dielectric blend. The yarns described above allows to generate electrochromic fabrics in which the colour can be varied by the application of small electric voltages fed by a battery with variable power supply controlled by a microprocessor connected to a smartphone via Bluetooth technology. A specific application on the smartphone allows to change the voltage supply to the fabrics, in order to get the desired chromatic change.

Fibrous product and fiber processing agent
Provided is a fibrous product that has excellent anti-allergen and antiviral properties, is capable of maintaining excellent outer appearance, and is less likely to cause color migration. Also provided is a processing agent for producing the fibrous product. The fibrous product of the present invention is characterized in having attached to the surface thereof (a) 1.0 to 3.0 g/m.sup.2 of zirconium phosphate, (b) 0.12 to 0.4 g/m.sup.2 of a homopolymer formed of an aromatic sulfonic acid monomer, and (c) 0.2 to 0.8 g/m.sup.2 of a copolymer including a styrene sulfonate salt. In addition, the processing agent of the present invention is characterized in being an aqueous dispersion that contains the components (a), (b), and (c) in a weight ratio of 1.0 to 3.0:0.12 to 0.4:0.2 to 0.8.
TRIBOELECTRIC GENERATOR
A triboelectric generator includes a set of two triboelectric elements. A first triboelectric element includes a nanofiber sheet and a coating of a first material having a positive triboelectric affinity. A second triboelectric element includes a nanofiber sheet and a coating of a second material having a negative triboelectric affinity. The first and second triboelectric elements are arranged so that confronting surfaces of the elements can reversibly contact one another. Repeated contact between the two triboelectric elements can transfer electrons and thus generate electrical energy. In some examples, a plurality of sets of first and second triboelectric elements can be arranged to increase surface area of contact between elements, and thus the amount of electrical energy produced per unit time.
