  • Preferred binders include the same synthetic polymers from which the filaments are prepared, i.e., polyolefins, polyamides, polyesters, and polyethers.
  • the filaments of the present invention can have either a circular cross-sectional profile or an asymmetrical cross-sectional profile.
  • the asymmetry of the filaments of the invention is determined by measuring their eccentricity (E).
  • Eccentricity (E) is measured by the following equation: wherein T max is the maximum thickness of the filaments and T min is the minimum thickness of the coating of the filaments.
  • T min is a positive integer that is substantially less than T max .
  • T min will be a positive integer that is larger than the value of T min for filaments having a one-sided asymmetrical profile.
  • the eccentricity (E) of the filaments is preferably an amount in the range of from about 0.3 to about 0.99 and, more preferably, from about 0.6 to about 0.9.
  • FIGURE 1 a preferred filament having a one-sided asymmetrical cross-sectional profile is shown.
  • the filament comprises a polymeric substrate (2) surrounded by an electroconductive coating (4).

  • T min is determined in the same manner. The distance of T min will be substantially less than T max .
  • the asymmetry is due primarily to an uneven coating of the electrically-conductive powder (8) on one side of the filament.
  • Another preferred filament has a two-sided asymmetrical cross-sectional profile, as shown in FIGURE 2.
  • the filament comprises a polymeric substrate (10) surrounded by an electrically-conductive coating(12).
  • T max is measured in the same way as the filament at its portion of greatest thickness, the distance from the outside of the polymeric substrate (14) to the inside of the electroconductive powder (16).
  • T min is determined in the same manner as the filament of FIGURE 1 by measuring the distance of minimum thickness from the outside of the polymeric substrate (18) to the inside of the electroconductive powder.
  • T min will generally have a greater value for filaments having a two-sided asymmetrical cross-sectional profile than filaments having a one-sided asymmetrical cross-sectional profile. In this filament, the asymmetry is due primarily to an uneven coating of the electroconductive powder (12) on two sides of the filament.
  • a particularly desirable feature of the filaments illustrated in FIGURES 1 and 2 is that they are self-crimping when heated, such as by contacting the filaments with steam.
  • the filaments of the invention can have a wide range of deniers. Filaments, particularly of polyamides such as nylon 6, having a denier/filament in the range of from about 5 and 50 find particular application in many apparel and floor covering applications.
  • the fibers preferably have an electrical resistance in the range of from about 104 to about 109 ohms/cm.

  • the amount of electrically-conductive powder coated on the surface of the filament will vary over a wide range with no limitation. The greater the quantity, the higher the conductivity of the filaments. If too much is applied, however, the physical properties of the filaments can be adversely affected. If very small amounts are applied, satisfactory electrical conductivity properties will not be obtained.
  • the filaments will contain from about 1 to about 30 weight percent of powder based on the weight of the synthetic polymer. Furthermore, the resulting electrically-conductive filaments will have a powder coating thickness of from about 0.5 to about 10 ⁇ m.
  • the coating of the electrically-conductive powder on the surface of the filamentary polymer substrate is preferably characterized by the existence of a discrete, independent phase of electrically conductive particles suffused into a non-conductive filamentary polymer substrate.
  • the polymer substrate is of substantially circular configuration, it has been found of especial advantage if the annular region of suffused electrically-­conductive particles extends perpendicularly inwardly from the periphery of the filament up to a distance equal to about 1/10 the radius of the filament. Under such conditions, the physical properties of the suffused filamentary substrate still closely approximate those of the unmodified filamentary substrate while the conductivity thereof has been strikingly increased.
  • the annular region most advantageously extends perpendicularly inwardly from the periphery of the filament up to a distance equal to about 1/10 the radius of a circle inscribed within the cross-sectional perimeter of the filament.
  • the electrically-conductive textile fiber of the present invention may be prepared for the filamentary polymer substrates using special techniques, the most satisfactory of which comprehend applying to the filamentary polymer substrate a disperson of the finely divided, electrically-conductive material in a liquid, preferably containing a binder, which is a good solvent for the substrate, but does not react with or dissolve the electrically-conductive material.
  • a combination of such liquids may be used if desired.
  • the chosen concentration of electrically-conductive material in the solvent system is dependent upon the desired fiber conductivity and is limited by the viscosity of the dispersion. (Dispersions which are either too viscous or not viscous enough are difficultly applied when certain methods of application are expedient.)
  • this dispersion to the filamentary substrate may be by padding, painting, spraying, dipping, rolling, printing, or the like.
  • the dispersion may contain dissolved polymer (binder) of the same nature as that of the substrate, under which conditions the annular suffusion terminates imperceptibly in an integral coating of the same composition.
  • solvent removal from the substrate must be effected before the structural integrity thereof is appreciably destroyed. This is conveniently accomplished by vaporization (for volatile solvents) and/or washing with a non-solvent (for non-volatile solvents) after the desired degree of solvent penetration has taken place (esp. up to about 1/10 of the radius of substantially cylindrical filamentary substrates).
  • the applicable dispersion when filamentary substrates of polyamides such as nylon 6 are employed, the applicable dispersion usually contains from about 15 to about 45 percent by weight conductive powder based on the total weight of the dispersion in a mixture comprising a solvent of formic acid and acetic acid or water.
  • the solvent may be advantageously removed by continuously passing the dispersion-treated filament through a chamber in which the air is continually exchanged, e.g., by means of air jets and/or means for evacuation.
  • the preferred methods of preparing the conductive filaments of the present invention are roller or orifice coating procedures.
  • a preferred roller coating procedure is disclosed in United States Patent 4,704,311, which is assigned to the assignee of the present invention and is hereby incorporated by reference.
  • the use of the roller coating procedure disclosed therein results in a conductive filament having the profile shown in FIGURE 2.
  • the two-sided asymmetry of the filament is due to the grooved, roll-type mix applicator disclosed therein, in which the grooves have a "V" cross section.
  • a coating comprising polymeric material can be subsequently applied to the filament coated with the electrically conductive powder to enhance the durability of the electrically conductive powder on the filament.
  • a symmetrical filament is illustrated containing a polymeric substrate (22), conductive coating (24) and an outer polymeric coating (26).
  • Asymmetrical filaments such as those illustrated in FIGURES 1 and 2 can also contain an outer polymeric coating.
  • the outer polymeric coating can comprise the same or different synthetic polymers from which the filaments are prepared.
  • Orifice coating techniques find particular application in preparing conductive filaments represented by FIGURE 1 wherein the coating is applied uniformly to the filament to produce a filament having two-sided asymmetry.
  • Other techniques of preparing the conductive filaments are known to persons skilled in the art.
  • the electrically-conductive filaments be subjected to heat treatment in order to increase the adhesion of the coating on the filaments.
  • the treatment is referred to as heatsetting.
  • the heatsetting operation is accomplished using either Superba equipment, in which case the filaments are subjected to steam at about 130°C-140°C, or Suessen equipment, in which case the filaments are subject to hot air at about 195°C-205°C.
  • the electrically-conductive textile fiber of the instant invention finds special utility in the production of fabrics, the use of which avoids the accumulation of high charges of static electricity while presenting no appreciable electrocution hazard.
  • woven fabrics are produced by standard interweaving of the electrically-conductive fiber of the instant invention with ordinary threads made from natural fibers such as cotton or wool, and/or man-made fibers such as nylon, rayon, acrylic or polyester.
  • the electrically-conductive fiber is preferably present in an amount equal to about 0.05-10.0, and preferably 0.1-5.0 percent by weight of the woven fabric.
  • pile fabrics can be produced comprising a backing material having pile loops anchored therein.
  • the backing material comprises chain yarns interwoven with filler yarns, as is very well-known in the art. Moreover, the backing material may be constructed from any of the materials commonly employed in the art, such as jute or hemp, among many others.
  • the pile loops comprise a yarn made of a plurality of strands twisted together by standard techniques. At least one such strand comprises the electrically-conductive fiber of the present invention.
  • the balance of the yarn comprises any commonly-employed natural or man-made fibers. As will be understood by one of skill in the art, it may not be necessary that every end of yarn in the pile contain a strand of the electrically-conductive fiber of the present invention.
  • the electrically-conductive fiber of the present invention is generally present in an amount equal to about 0.05-10.0, and, preferably, 0.1-5.0 percent by weight of the pile fabric.
  • Fabrics such as those of the preparation of which is outlined above when employed in an atmosphere having a relative humidity of 20%, will not generate a static charge above about 3000 volts, which is in proximity to the threshold level of human sensitivity.
  • These fabrics moreover, when containing an especially-preferred embodiment of the electrically-conductive fiber of the present invention, do not present an electrocution hazard to those contacting them in the event of an accidental and simultaneous contact of such fabrics with a source of essentially unlimited electrical current, as is available from an ordinary electrical outlet, or an electrical appliance short-circuited by insulation failure.
  • An electrically conductive filament was prepared utilizing an electrically conductive coating composition containing the following ingredients: Coating Composition Tin Oxide/Antimony Oxide Powder 25% Nylon 6 Chips 5% Dispersing Agent 1% Formic Acid 48% Water 21%
  • the tin oxide/antimony oxide powder contained 99 percent by weight tin oxide and 1% by weight antimony oxide. At least 25.0 weight percent of the powder based on the total weight of the antimony oxide and tin oxide has an average particle size of at least 0.5 ⁇ m, but less than 1.0 ⁇ m. The remainder had an average particle size of less than 0.5 ⁇ m.
  • the coating composition was prepared by dispersing the tin oxide/antimony oxide powder, formic acid, water, and dispersing agent using a suitable mill (sandmill, ballmill, etc.). Next, the nylon 6 chips were dissolved in the dispersion. The coating composition was then applied to a 20 denier nylon monofilament using a kissroll or low pressure (-2 PSIG) die with an internal diameter of 75 microns. The formic acid and water was then removed from the monofilament by evaporation using a dryer. The dry, coated, electrically-conductive filament, which had a denier of 24.5, was then wound on a tube. Using a FLUKE 8020 Electrometer, the electrical resistance of the filament was determined to be 1 x 108 ohms/cm.
  • An electrically conductive filament was prepared utilizing a coating composition containing the following ingredients: Coating Composition Tin/Antimony Oxide Powder 35.0% Nylon 6 Chips 4.0% Dispersing Agent 0.4% Formic Acid 18.0% Acetic Acid 40.6% Water 2.0%

Next the nylon chips were added to the mixture and dissolved. This premix was then pumped through a sandmill to affect total disperson of the tin oxide/antimony oxide particles. A nylon monofilament having a denier of 15 was coated using the coating composition in the same manner as described in Example 1. The resulting filament, which had a denier of 19.5, was measured for electrical resistance. The resistance was determined to be 8 x 107 ohm/cm.

  • the coating composition was prepared in the same manner as Example II except that one half of the total amount of acetic acid utilized therewith was added to the mixture after the nylon 6 chips were added rather than during the predispersion step as in Example II. The predispersion was then sandmilled in the same manner as Example II.
  • the coating mixture is not a particularly good solvent for nylon 6 and, therefore, is particularly suitable for coating nylon 6 monofilaments having a denier of 7 using the roller coating procedure.
  • An electrically conductive filament was prepared utilizing a coating composition containing the following ingredients: Coating Composition Tin/Antimony Oxide 40.0% Nylon 6 Chips 0.2% Dispersing Agent 0.1% Formic Acid 18.0% Acetic Acid 39.7% Water 2.0%
  • the coating composition was prepared in the same manner as Example III.
