Definitions

  • the present invention relates to specially coated sleeves, a process for their production and their use in the winding of glass fibers.
  • the glass fibers are usually wound onto so-called cores after they have been pulled out of the so-called bushing. These wound glass fibers are then dried together with the sleeve, the so-called cake. After the drying process, the sleeve is removed by pulling it out of the side of the cake. The wound glass fiber is then processed further.
  • the sleeves are made of reinforced or unreinforced paper or reinforced or unreinforced plastic and are uncoated or partially coated with polyurethanes.
  • JP-A-53-58034 (Derwent AN 78-48316A) describes the coating of paper or plastic sleeves for winding polyester filaments with dimethylpolysiloxanes, methylpolysiloxanes or modified siloxanes.
  • WO-A-90/10244 describes aluminum sleeves which are coated with an elastic layer of a silicone compound in order to prevent the wound-off optical fibers from slipping off.
  • DE-A-1801325 describes friction-reducing lubricants for glass fibers which consist of an organopolysiloxane emulsion.
  • a dimethylpolysiloxane emulsion is preferably used, but some of the Si-bonded radicals can also be replaced by, among others, hydrogen atoms or higher alkyl groups.
  • FR-A-2 291 253 describes abhesive coating compositions which, in addition to a crosslinkable polydiorganosiloxane, also contain a polysiloxane with hydrogen bonded to silicon and / or with longer-chain alkyl groups bonded to silicon.
  • EP-A-0 356 827 describes a lubricant based on hydrogen polyorganosiloxanes, which can also have longer-chain alkyl substituents. In the examples only methyl groups are mentioned.
  • DE-A-27 51 803 describes a process for the adhesive coating of flat materials, in particular plastic films or paper.
  • a preparation based on methylalkoxysiloxanes and a hardener is applied to the material and exposed to elevated temperatures.
  • the invention relates to sleeves on which the glass fiber
  • the radicals R 1 , R 2 , R 3 and R 5 of the silicone oils are preferably methyl groups.
  • the sleeves are preferably coated with silicone oils of the above general formula in which R 4 represents a dodecyl and / or tetradecyl radical.
  • the silicone oil or resin is suitably, i.e. e.g. applied to the sleeve by roller coating, dipping or spraying. If silicone resins are used, salts of tin, iron, titanium, lead or aluminum are added to them individually or as a mixture, so that the resins can crosslink with the sleeve. Titanium tetrabutylate and / or dibutyltin dilaurate are preferably used as catalysts.
  • the sleeves according to the invention are used in the winding of glass fibers.
  • the sleeves used hitherto were treated by the process according to the invention and were also used in the winding of various glass fibers. As can be seen from Table 1, the sleeves according to the invention could be pulled out of the cake with almost no loss of glass fibers. The loss of glass fibers when using the sleeves according to the invention is thus considerably less than when using the known sleeves.
  • the glass fiber is wound onto this sleeve and the cake thus obtained is dried. Then the glass fiber is freed from the sleeve by pulling the sleeve out of the side of the cake. The sleeve can then be used again.
  • Table 1 The results are listed in Table 1.
  • the sleeve could be removed with little loss of fiber.
  • the sleeve is used in accordance with Example 1.
  • the sleeve is then dried at 80 ° C for 30 minutes.
  • the glass fiber is wound onto this sleeve and the cake thus obtained is dried.
