  • Patent number: 4232082
    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.
