Definitions

  • the present invention relates to a formulation for use as a lubricant in the manufacture of filaments.
  • the threads are first prepared by a spinning process, which is preferably the solvent spinning process, and then further processed by applying the formulation of the invention on the surface of the threads as a lubricant.
  • the threads produced are preferably cellulose acetate threads and these threads are used to make filters for tobacco products, especially cigarette filters.
  • the patent GB 896,599 describes tobacco filters that can be used in cigarettes, pipes, cigarette holders or cigar tips.
  • the filter elements described consist of bundles of continuous synthetic filaments, wherein water-insoluble calcium or magnesium salts are finely distributed on the surface of the filaments. These finely divided particles are fixed by oils on the fibers. In addition to mineral oils, these oils may also be high-boiling liquid esters of natural origin, liquid esters of natural fats or liquid high molecular weight fatty alcohols.
  • the patent GB 765,962 describes a tobacco filter element consisting of cellulose acetate fibers.
  • the cellulose acetate filter material is subjected to various processing steps, such as stretching and crimping of the fibers.
  • electrostatic charging of the fibers must be prevented, 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.
  • This lubricant contains a mineral oil with a purity that would make it suitable for the manufacture of pharmaceutical products.
  • a rigid tobacco smoke filter consisting of a bundle of optionally crimped continuous filaments and a paper wrapper is described.
  • the filaments consist of a mixture of a polyalphaolefin and a plasticizer-soluble polymer of an organic plasticizer.
  • Liquid organic plasticizers which can be used in addition to light, medium and heavy mineral oils, liquid high-boiling organic esters or water-insoluble propylene glycols or polybutylene glycols.
  • a cleaning composition containing white mineral oil is described.
  • the emulsion is used for the treatment and cleaning of metal surfaces.
  • the emulsion of the invention contains 20-50 wt.% Of a mineral oil having a viscosity of 50-380 Saybolt seconds, measured at 100 ° F and 0.5 to 10 wt.% Of an emulsifier.
  • nonionic emulsifiers has been found to be advantageous.
  • sorbitan esters and polyglycerides of fatty acids are also mentioned.
  • emulsifier should be present in the emulsion as is just necessary to form a stable emulsion. In this case, 0.5 to 10% by weight of the emulsifier are present in the emulsion, with 1 to 5% by weight of emulsifier being preferred. If more emulsifier is present in the emulsion, milky stains or streaks may remain on the cleaned surface after cleaning.
  • a thread which normally contains cellulose acetate
  • a spinning process which is preferably the solvent spinning process.
  • an acetone solution of cellulose acetate and matting agent TiO 2 is pressed through shower-like nozzles (spinnerets).
  • the holes usually have cross sections in the form of an equilateral triangle.
  • a heated spin shaft Below the spinnerets is a heated spin shaft. The air sucked through the spinning shaft heats up and absorbs the solvent which diffuses out of the formed filament, acetone, which almost is completely recovered.
  • the solution solidifies under considerable volume shrinkage to a filament.
  • the filaments When using triangular holes, the filaments have a Y-section.
  • the filaments in the thread When a thread composed of several filaments leaves the spinning shaft, the filaments in the thread are densely packed without, however, sticking to each other.
  • the thread At the exit of the spinning shaft, the thread typically contains a residual fraction of about 1 to 6% by weight of acetone.
  • the thread is provided with a preparation (avivage), which serves mainly as a lubricant for the subsequent processing steps. This preparation is carried out by an oiler or by means of an applicator roll.
  • the content of acetone in the threads is first further reduced, a plurality of threads are combined to form the so-called rope and the rope is subjected to a crimping process by means of 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, ie the thickness of the filter to be produced.
  • a glycerol triacetate-containing composition is applied to the filter tow. This further preparation, after leaving the compression part by curing, fixes the filter in the desired shape and thickness.
  • the formulation applied after the threads have dried acts as a lubricant. It ensures, inter alia, that the friction which occurs during the subsequent processing steps does not exceed a value which leads to the breakage or undesired heating of the threads or the rope. Both would cause unwanted rejects.
  • the lubricant enables higher machine speeds. The formulation must withstand the high shear forces associated with this process without loss of effect.
  • This lubricant usually consists of an emulsion which is prepared from a mixture of low-viscosity mineral oil and emulsifier. Other components may be included in the emulsion.
  • the mineral oils remain on the threads after the manufacture of the filters and the corresponding tobacco products containing these filters. For example, when smoking a cigarette containing such a filter, some of the mineral oil that is on the filter may be absorbed by the smoker.
