Definitions

  • the invention relates to a biodegradable filter according to Preamble of claim 1.
  • paper filters are an ecological one optimal solution. The low success of pure paper filters but is based on several material-specific properties of the paper.
  • paper filters The main problem with paper filters is the difference in taste of smoke compared to conventional cellulose acetate filter cigarettes. They make other problems clear different retention, significantly worse hardness with the same retention and a coarse-pored structure of the filter cut surface compared to cellulose acetate filters.
  • the paper is in fleece or Leaf form, the cellulose acetate in fiber form before. All attempts about different processing methods, e.g. B. the different strong crimping or pleating of the paper web to the optical and haptic properties of the cellulose acetate failed to achieve. So far there is none Process known the paper in its chemical retention properties to change so that it corresponds to the acetate.
  • Double filters which contain a paper and a cellulose segment, constructed.
  • This embodiment is due to complicated manufacturing techniques expensive and not yet optimal from an ecological perspective.
  • EP 0 032 044 B1 discloses a method for producing fiber webs with loosely packed fibers, in which the dry fibers are applied to a carrier web in a sieve in an air stream.
  • the fibers are not subjected to cross-flow forces as they pass through a forming head and exit therefrom, thereby maintaining a substantially uniform basis weight in the transverse direction of the fiber web. It can be used to produce fiber beds with basis weights of more than 70 g / m 2 .
  • This known method is also referred to as an "air-laid" method. Due to the fluffiness of the cotton-like material, however, it was not possible to manufacture cigarette filters.
  • EP-A-0 711 512 discloses a cigarette filter consisting mainly of cellulose esters.
  • the filter material ie the cellulose ester, can also contain other substances which are referred to as secondary or secondary components. These other substances, which may also be present, include natural cellulose.
  • the object of the invention is to develop a monofilter which is significantly more biodegradable than cellulose acetate and at the same time maintains the taste impression, the appearance, the hardness and the retention property of cellulose acetate indistinguishably for the consumer, the production should be possible in a simple manner ,
  • the processed cellulose fibers are not suspended in water as in the classic paper production process and placed on a permeable sieve to form sheets, on which the cellulose fibers then cross-link with each other due to their grinding and fibrillation, but they are separated as much as possible placed in an air stream, which transports them onto a permeable endless sieve and places them on this in an unordered manner.
  • a mechanical bond and thus the necessary strength, which is required for further processing, is obtained by adding a binder such as e.g. As polyvinyl alcohol, polyvinyl acetate, polymer starch, dextrin or latex.
  • the degree of density (g / cm 3 ) and thus the volume or thickness is set by means of subsequent calendering.
  • the weight per unit area (g / m 2 ) is controlled via the sieving speed or the fiber entry into the air flow.
  • the five fibrous web strips 1-5 which are obtained by longitudinal cuts in the fibrous web 10 of FIG. 1, are first folded in a V-shape by a suitable device, as shown in FIG.
  • the free ends of the V-shaped fibrous web strips 1-5 are then placed next to one another and the strips are brought together by a suitable device such that the apex 14 of the V-shaped fibrous web strips are arranged in the area around the central axis of the cigarette filter to be produced and are thus spirally adjacent to one another a cylinder jacket are rotated, as indicated schematically in Figure 3 in cross section.
  • the individual fibrous web strips 1-5 are so close together after the spiral winding according to FIG.
  • the fiber web strips 1-5 wound according to FIG. 3 are held together in the usual way by a filter covering paper 12, so that the paper filter according to the invention has the appearance of a cellulose acetate filter after its completion.
  • the analytically and physically determined data are corresponding valid DIN / ISO regulations have been created and show no differences within the measuring accuracy.
  • the Taste rating was assessed by 15 trained smokers performed and resulted in insignificant comparisons in pairs Differences.
  • the biodegradation of the cigarette filter material according to the invention takes place within a period of time comparable to that of commercially available (cigarette) cellulose filter material. This means a clear improvement over the cellulose acetate.
  • the biodegradation is assessed according to the "storm test” used in industry, which was described by RN Sturm in J. Americ. Oil Chemists' Soc. 50 (1973) May, pp. 159-167 in the article "Biodegradability of nonionic surfactants: screening test for predicting rate and ultimate biodegradation".
