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.
Claims12
An electrically conductive fiber comprising an organic polymeric fiber matrix and copper (I) iodide which is located in the inside of at least the peripheral surface layer of said organic polymeric fiber matrix and which is in an amount sufficient to cause the electric resistivity of the conductive fiber under a D.C. voltage of 1 K.V. at a temperature of 20.degree. C. and at a relative humidity of 65% to be 1.times.10.sup.12 ohm/cm or less.
A method for producing an electrically conductive fiber which comprises an organic polymeric fiber matrix and copper (I) iodide contained within at least the peripheral surface layer of said organic polymeric fiber matrix, and which exhibits an electric resistivity of 1.times.10.sup.12 ohm/cm or less under a D.C. voltage of 1 K.V. at a temperature of 20.degree. C. and at a relative humidity of 65%, said method comprising bringing iodine into contact with copper (I) ions in the inside of at least the peripheral surface layer of said organic polymeric fiber matrix and depositing the resultant copper (I) iodide therein in an amount sufficient to result in the above-mentioned level of electric resistivity of the resultant conductive fiber.
