Definitions
- the invention relates to a biodegradable filter according to the preamble of claim 1.
- paper filters are the optimal solution for cigarettes.
- the low success of pure paper filters is due to several material-specific properties of the paper.
- the main problem with paper filters is the different taste of the smoke compared to conventional cellulose acetate filter cigarettes.
- Other problems are the significantly different retention, a significantly poorer hardness with the same retention and a coarse-pored structure of the filter cut surface in comparison to cellulose acetate filters.
- the paper is in fleece or Leaf form, the cellulose acetate in fiber form before. All experiments using different processing methods, e.g. B. the different degrees of crimping or pleating of the paper fleece to achieve the optical and haptic properties of the cellulose acetate have failed. Likewise, no method is known to date to change the paper's chemical retention properties in such a way that it corresponds to the acetate.
- cigarettes are now constructed with double filters that contain a paper and a cellulose segment.
- This embodiment is expensive due to complicated manufacturing techniques and is not yet optimal from an ecological point of view.
- 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 an air stream in a sieve. The fibers are not subjected to transverse flow forces as they pass through and exit from a forming head, 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, no cigarette filters could be produced with it.
- the object of the invention is to develop a monofilter which is significantly better 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 processed cellulose fibers are not suspended in water as in the classic paper manufacturing process and placed on a permeable sieve to form the sheet, on which the cellulose fibers then cross-link with each other due to their grinding and fibrillation, but rather become cross-linked at most, they are 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.
- FIG. 1 shows a fiber web produced by the air-laid method with cutting lines running in the longitudinal direction;
- Figure 2 shows the indicated manner of folding the cut fiber web strips;
- FIG. 3 shows the spiral winding of the fiber web strips from FIG. 2.
- the five fibrous web strips 1-5 which are obtained by longitudinal cuts in the fibrous web 10 of Figure 1, are first folded according to the invention by a suitable device in a V-shape, as shown in Figure 2.
- 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 in such a way that the apex 14 of the V-shaped fibrous web strips are arranged in the region around the central axis of the cigarette filter to be produced and are spirally adjacent to one another be turned into a cylinder jacket, as indicated schematically in FIG. 3 in cross section.
- 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 biodegradation of the cigarette filter material according to the invention takes place within a comparable period of time as with 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 the industry by R.N. Storm in J. Americ. Oil Chemists' Soc. 5J1 (1973) May, pp. 159-167 in the article "Biodegradability of nonionic surfactants: screening test for predicting rate and ultimate biodegradation".
