Abstract: An electrically conductive fiber having an electric resistivity of 1.times.10.sup.12 ohm/cm or less under a D.C. voltage of 1 K.V., contains copper (I) iodide which has been deposited in the inside of at least the peripheral surface layer of an electrically non-conductive fiber matrix by contacting iodine with copper (I) ions therein.

Abstract: A coating composition useful in forming conductive layers comprises a latex having water as a continuous phase and, as a dispersed phase, hydrophobic polymer particles having associated therewith a polyaniline salt semiconductor. The coating composition can be coated on a variety of supports to produce conductive elements. The coating compositions are particularly useful in forming antistatic layers for photographic elements or conducting layers for electrophotographic and electrographic elements. Also disclosed is a preferred process for preparing a latex coating composition comprising the steps of loading polymer particles with the polyaniline component of the polyaniline acid addition salt semiconductor and then acidifying the latex to form a polyaniline salt coating composition.

Abstract: An electrically less chargeable wool-polyester suiting woven or knitted mostly from a non-electroconductive yarn and partly from an electroconductive yarn of the type containing a carbon-black-coated mono-filament fiber. The suiting comprises 0.1% to 0.6% of the mono-filament fiber for obtaining a necessary anti-electrostatic effect. The monofilament fiber in the electroconductive yarn is covered by wool and other fibers having an aggregate amount by weight more than its fivefold amount and an average single-fiber finess less than its one-fifth finess, so that it is prevented from appearing streaky on the surface of the suiting. The electroconductive yarn in the suiting is protected from interruption both in production and in use by the non-electroconductive yarn including polyester multi-filament fibers.

Abstract: A laundry finishing treatment rope for use in a mechanical laundry drier comprising an entwined strand of textile fibers in a cord form having both ends secured against fraying, the rope being impregnated with 10% to 90% by weight of a substance of the laundry finishing treatment type effective in a mechanical laundry drier; as well as the method of finishing laundry by tumble drying the laundry in the presence of the rope in a mechanical laundry drier.

Abstract: An antistatic filament having a polymeric sheath and a conductive polymeric core of a defined nature, the core constituting less than 10% of the cross-sectional area of the filament.
