Definitions

  • the critical amount of the electrodeposited metal depends on the physical properties of the metal such as hardness, density, ductility and degree of crystallinity, as well as on those of the textile carrier material such as modulus of elasticity, degree of crystallinity and molecular weight.
  • the advantages achieved by the invention are, in particular, that the threads, fibers and textile fabrics, which are preferably galvanically reinforced with Ni, Cu, Sn, Zn, Pb, Au, Ag, Pd, Pt and Cd, have excellent thermal and electrical conductivity. It is also surprising that the products obtained according to the invention have excellent compatibility in thermoplastics or thermosets.
  • the continuous galvanic reinforcement is preferably carried out with movement of the goods, for example by guiding the metallized textile material to be galvanically reinforced in the electroplating bath so that its direction of transport changes at least twice, preferably several times. This prevents sticking at the yarn or stitch crossing points due to excessive metal separation.
  • the metal layer to be reinforced can be applied electrolessly, wet-chemically, for example in accordance with DE-OS 2 743 768, or in any other way, for example by vapor deposition or " S pattern " using the cathode-ray method.
  • the present invention therefore relates to a process for the production of metallized textile fabrics, such as woven fabrics, knitted fabrics, fleeces, felts, etc., from native or synthetic threads or fibers, characterized in that the textile fabric is coated with an electrically conductive metal layer and this metal layer galvanically reinforced.
  • the metal layer to be reinforced can be varied within wide limits. However, on the one hand, it should ensure a uniform current flow, on the other hand, it should be as thin as possible for economic reasons. Metal layers of 1 to 20 g metal / m textile fabric are therefore preferred.
  • the thickness of the electrodeposited metal layer is between 10 and 40 g / m 2 for copper, nickel and cobalt, and between 10 and 250 g / m 2 for gold, lead, tin, cadmium.
  • the galvanic reinforcement can be carried out with acidic and alkaline galvanizing baths.
  • the process according to the invention has the advantage that expensive reducing agents, such as diethylaminoborane, sodium borohydride, sodium hypophosphite, which are consumed in the chemical deposition of the metal on the substrate surface, are replaced by the inexpensive electric current.
  • expensive reducing agents such as diethylaminoborane, sodium borohydride, sodium hypophosphite
  • Another advantage of the present galvanic amplification method is that it is much lighter Manageability of the galvanic baths.
  • the pH value and composition have to be analyzed again and again and the missing components added.
  • a reductively deposited metal coating that is sensitive to oxidation can be protected against oxidants such as oxygen in the air by an insensitive metal layer.
  • the electrolytically deposited metal layer shows good heat resistance, strong reflectivity for incident electromagnetic radiation.
  • metallized textile fabrics are e.g. suitable for the production of flexible shield antennas for radar waves.
  • a polyester-cotton staple fabric (10 x 10 cm) is immersed in a hydrochloric acid colloidal palladium solution at room temperature for 2 minutes, rinsed with distilled water, placed in a 5% by weight sodium hydroxide solution for 2 minutes, washed with distilled water and in for 15 minutes copper-plated in a reductive alkaline copper bath at room temperature.
  • the tissue is rinsed, switched as cathode in an acidic galvanic copper bath and reinforced with 29.6 g / m 2 copper at 1.0 ampere in 30 minutes.
  • a textile-elastic fabric is obtained, the electrical resistance of which is 0.7 cm at a distance of 2.0 cm in the weft direction and warp direction.
  • a square (10 x 10 cm) of a 100% polyacrylonitrile spun fiber fabric in plain weave is copper-coated according to example 1 and then reinforced in a galvanic copper plating bath at 1.25 amperes in 27 minutes with 33.3 g / m 2 copper.
  • a 10 x 10 cm square of a knitted fabric of polyethylene terephthalate is immersed at room temperature in an activation bath of 0.4 g of 4-cyclohexene-1,1-dicarboxylic acid anhydride-palladium (II) chloride in 1 1 CH 2 Cl 2 , after one minute Bath removed, at ' room temperature dried and then chemically provided with a 12 g / m 2 thick nickel coating in an alkaline nickel plating bath for 10 minutes.
  • the knitted fabric is coppered according to Example 1 at 1.5 amps in 17 minutes with 25 g / m 2 .
  • a 10 x 10 cm square of a knitted fabric made from a polyacrylonitrile yarn is carefully coated with 12 g / m 2 of nickel at room temperature in accordance with Example 1, rinsed with distilled water and in a semi-gloss nickel bath at room temperature as a cathode at 1.0 ampere in 30 minutes with 28 , 3 g / m 2 of nickel reinforced.
  • the textile properties of the knitted fabric are retained.
  • a 10 ⁇ 10 cm square of a cotton spun fiber fabric is copper-coated according to Example 1 and then reinforced according to Example 4 with nickel. After 30 minutes you get a fabric with 27.5 g / m 2 nickel coating.
  • a 9 x 14 cm polyester cotton fabric is immersed at room temperature in a bath of 0.3 g of 4-cyclohexene-1,1-dicarboxylic acid anhydride palladium (II) chloride in 1 liter of methylene chloride, after one minute of the bath removed, is provided at room temperature and then dried in 8 minutes by chemical means with a 15 g / m 2 thick nickel plating .
  • D as N ickelbad contains 30 g / l nickel chloride 3 g / 1 dimethylamine borane and 10 g / 1 citric acid and was adjusted to pH 8.1 with ammonia.
  • the long sides of the tissue were contacted with a steel wire, attached to the cathode with the wires in a galvanizing apparatus and immersed in a tinning bath. At a current of 10 amperes, 9 g of tin / m 2 were deposited at room temperature in 3 minutes.
  • the tin bath contains 80 g / 1 stannous sulfate, 50 g / 1 sulfuric acid, 100 g / 1 cresol sulfonic acid, gelatin and ß-naphthol.
  • a 9 x 14 cm rectangle made of a polyester-cotton fabric was pre-nickel-plated according to Example 6 and then tinned. 37 g / m 2 of tin were deposited within 8 minutes at room temperature and at a current of 10 amperes. The fabric retained its textile character.
  • a fabric of polyester cotton yarn (9 x 14 cm) was activated in a bath of 0.4 g of 4-cyclohexene-1,1-dicarboxylic acid anhydride-palladium (II) chloride and one liter of methylene chloride, and after drying the Coat the fabric chemically with a 13 g / m 2 nickel coating at room temperature in 7 minutes.
  • the long sides of the tissue were contacted with a steel wire, attached with the wires on the cathode to a galvanizing system and immersed in a tinning bath. At at a current of 10 amperes, 31 g of tin / m 2 were electrodeposited on this nickel-plated fabric within 3 minutes. The rinsed and dried fabric retained its textile character.
  • Example 8 a 9 x 14 cm polyester cotton fabric was chemically nickel-plated and then galvanized. At a current of 10 amps, 80 g / m 2 of zinc were deposited at 30 ° C. for 8 minutes. The galvanized fabric piece showed great flexibility and textile character.
  • a fabric sheet continuously nickel-plated according to DOS 3 025 307, Example 10 is first drawn through a 5% hydrochloric acid and then through a galvanizing line according to FIG. 1.
  • the anodes are arranged parallel to the fabric.
