Definitions
- the invention relates to: a cigarette filter according to the preamble of patent claim 1 and a method according to the preamble of patent claim 17.
- Paper filters are increasingly being used for cigarette filters. Paper is often used for the construction of light and ultra-light cigarettes because of its very good retention properties. A major disadvantage, however, is the change in taste caused by a paper filter compared to a cellulose acetate filter commonly used. Paper filters are therefore not suitable as monofilters, but only as so-called. Double, dual or multiple filters in connection with other filter material. However, the production of multiple filters is extremely complicated and very expensive.
- cellulose acetate is thus applied to a paper web in the melt-blown process.
- This material produced as a monofilter, surprisingly shows the same retention and taste properties as conventional multiple filters with the same total retention.
- This novel filter material can be produced in the melt-blown process by using smooth or pre-creped paper webs which are multi-layer, preferably single-layer, in a weight range of 8 to 50 g / m, preferably 15 to 30 g / m, that the inflated, melted cellulose acetate has a degree of acetylation of 1 to 3, preferably 1.7 to 2.6.
- This cellulose acetate is preferably a cellulose acetate softened with triacetin, the triacetin softening the wall of the cellulose acetate fibers so that they adhere to one another at their crossing or contact points.
- This binder can be a hot melt adhesive or e.g. a modified extrudable and meltable starch. The latter is particularly recommended from an ecological point of view. In any case, care must be taken to ensure that the processing temperature of the binder does not affect the nature of the cellulose fibers subsequently applied.
