Definitions

  • the present invention relates to a formulation for use as a lubricant in the manufacture of threads.
  • the threads are first produced by a spinning process, which is preferably the solvent spinning process, and then further processed as a lubricant while applying the formulation according to the invention to the surface of the threads.
  • the threads produced are preferably cellulose acetate threads and these threads are used for the manufacture of filters for tobacco products, especially cigarette filters.
  • the patent specification GB 896,599 describes tobacco filters which can be used in cigarettes, pipes, cigarette holders or cigar holders.
  • the filter elements described consist of bundles of continuous synthetic filaments, water-insoluble calcium or magnesium salts being present in finely divided form on the surface of the filaments. These finely divided particles are fixed on the fibers by oils.
  • these oils can also be high-boiling liquid esters of native origin, liquid esters of natural fats or liquid high-molecular fatty alcohols. 0

  • the cellulose acetate filter material is subjected to various processing steps, such as, for example, stretching and crimping the fibers.
  • processing steps such as, for example, stretching and crimping the fibers.
  • an electrostatic charging of the fibers must be prevented on the one hand and on the other hand the surface of the fiber must be provided with a lubricant so that the fiber can be subjected to these processing steps.
  • a lubricant contains an o mineral oil with a purity with which it would also be suitable for the manufacture of pharmaceutical products.
  • DE 12 12 459 describes a stiff tobacco smoke filter which consists of a bundle of optionally crimped continuous threads and a paper wrapper.
  • the threads consist of a mixture of a polyalphaolefin and a plasticizer-soluble polymer of an organic plasticizer.

If there is more emulsifier in the emulsion, milky stains or streaks may remain on the cleaned surface after cleaning.
  • the manufacture of filters for tobacco products usually takes place according to a process in which a thread, which normally contains cellulose acetate, is first produced using a spinning process, which is preferably the solvent spinning process.

  • the thread At the exit of the spinning shaft, the thread typically contains a residual proportion of approximately 1 to 6% by weight of acetone.
  • the thread is provided with a preparation (finish) which mainly serves as a lubricant for the subsequent processing steps. This preparation is carried out by an oiler or with the help of an application roller.
  • the content of acetone in the threads is first further reduced, several threads are combined to form the so-called tau, and the tau is subjected to a crimping process using a crimping machine, which preferably works according to the stuffer box principle.
  • this rope is passed through a conical machine part and thus compressed to its final thickness, that is to say the thickness of the filter to be produced.
  • a composition containing glycerol triacetate is applied to the filter rope. After leaving the compression part, this further preparation ensures that the filter is fixed in the desired shape and thickness by curing.
  • the formulation applied after the threads have dried serves as a lubricant. It ensures, among other things, that the friction that occurs during the subsequent processing steps does not exceed a value that leads to the tearing or undesirable heating of the threads or the rope. Both would result in undesirable waste.
