Definitions

  • the advantages of the overall process lie in the high efficiency of the filter tow production, the low transport costs from the filter tow manufacturer to the end customer and in particular the high productivity in the filter production, which is not insignificantly determined by the length of the belts in the bales.
  • Filter Tow is processed on commercially available filter rod machines, such as, for example, the KDF 3 / AF 3 from Körber AG, Hamburg. Production speeds of currently 600 m / min are state of the art.
  • the productivity of filter production can be increased significantly when using the double-strand technology described in DE-A-43 40 029 and when using the twin-tow technology shown in DE-A-43 20 303.
  • the invention is therefore based on the object of providing surface filters based on endless cellulose ester fibers which do not have the disadvantages of the prior art explained above, in particular of the filter described in US Pat. No. 4,007,745. Even without three-dimensional crosslinking, these should have sufficient hardness, and their mechanical disintegration capability should correspond to that of surface filters which were produced from nonwovens with short-cut fibers.
  • the Filtrona hardness should be based on the market requirements.
  • the area filters are to retain the advantageous properties known from the prior art or, in individual cases, improved properties.
  • a filter plug can be heated in an inert gas stream and the evaporation kinetics can be verified by combustion in a commercially available flame ionization detector (FID).
  • FID flame ionization detector
  • the evaporation rate one in the Fiber evenly applied plasticizer differs sustainably from that of a superficially applied plasticizer. Since the evaporation is diffusion-controlled, the evaporation kinetics are significantly slower with even distribution than with surface application. Another possibility is to display the evaporation kinetics using differential thermogravimetry. Thirdly, the uniform distribution can be determined by short-term extraction methods in solvents suitable for the polymer with subsequent quantitative analysis of the plasticizer.
  • the ratio of fiber weight / tensile resistance S based on the filament titer according to the formula described above is greater than approximately 0.7. If this value is undershot, this leads to retention values as are customary in conventional cellulose acetate feeds.
  • the fiber weight / tensile resistance ratio S based on the filament titer is preferably at most about 2, and is in particular in the range from about 0.8 to 1.3. If the preferred value of about 2 for the ratio S is exceeded, then this product no longer meets the desired economic requirements.
  • the following general conditions preferably apply:
  • cellulose acetate flakes were introduced into a double-walled universal mixer with a total volume of 615 liters and a cooling / heating device.
  • the mixing tool 1 is in one piece with three blades all the way around the bottom and placed vertically on the drive shaft.
  • a one-piece, four-bladed chopper tool 2 is attached horizontally to the drive shaft, which prevents agglomerate formation during the addition and diffusion of plasticizer and is operated at a peripheral speed of 21 m / sec (2890 rpm).

Abstract

La présente invention concerne un filtre à cigarette hautes performances à base de fibres ou de filaments d'esters de cellulose pouvant être dégradé mécaniquement. Ce filtre à cigarette hautes performances se caractérise en ce que: a) le rapport poids de fibre (ou poids de filament)/résistance à la traction S se basant sur le titre de filament, est supérieur à environ 0,7, la valeur de S étant calculée d'après la formule S = (mA / DELTA P7,8 / dpf [10m/daPA], dans laquelle mA est le poids de fibre, DELTA P est la résistance à la traction et dpf est le titre de filament, et la valeur calculée pour un diamètre de 7,8 mm est utilisée pour la résistance à la traction; b) le reste de la texturation du matériau de filtre ne dépasse pas 1,45; c) le poids de fibre vaut au maximum 10 mg/mm de la longueur du filtre; et d) la dureté du filtre à cigarette est supérieure à environ 90 % de la dureté filtrona. Ce filtre se caractérise par une dégradabilité dans des conditions environnementales améliorée par rapport à des produits de la même catégorie.
