Description
Zigarettenfilter Die Erfindung betrifft Zigarettenfilter mit selektiver, hochaktiver Wirkung.
Es ist bekannt, die verschiedensten Materialien, wie gerippten Zellstoff, Celluloseacetat, Aktivkohlen, als Filter für Zigaretten einzusetzen. Diese gebräuchlichen Filtermaterialien sollen selektiv die unerwünschten und schädlichen Bestandteile des Zigarettenrauches zurück- halten, ohne Beeinträchtigung des Geschmackes.
Es wurde nun gefunden, dass Kohlenstoffasern einen besonders wirkungsvollen Filter für Zigaretten darstel len. Die Kohlenstoffasern können als Watte, Gewebe und lockere Filze zur Anwendung kommen. Vorzugs weise werden Kohlenstoffasern mit gestörter Oberfläche verwendet, d. h. solche Fasern, deren Oberfläche rauh ist, deren Oberfläche Erhebungen und Vertiefungen auf weist.
Die Kohlenstoffasern können durch Verkoken von Polyacrylnitril, Baumwolle, regenerierter Zellulose u. a. hergestellt werden. Vorzugsweise werden Kohlenstoff fasern angewendet, die bei der Verkokung von Poly- acrylnitril oder Baumwolle erhalten werden.
Die Kohlenstoffasern können allein als Filtermaterial eingesetzt werden; vorteilhafterweise aber werden sie in Kombination mit anderen Filtermaterialien, z. B. geripp tem Zellstoff, Zelluloseacetat, verwendet. Dabei wird der dem Mund zugekehrte Teilzweckmässig aus geripptem Zellstoff oder Zelluloseacetat bestehen.
In der nachstehenden Tabelle sind Vergleichsver suche der erfindungsgemässen Filter mit herkömmlichen Filtern dargestellt. Die Art und Menge des verbrauchten Tabaks waren immer die gleichen, ebenfalls die physika lischen Bedingungen (Temperatur, Luftfeuchtigkeit).

Cigarette filters The invention relates to cigarette filters with a selective, highly active effect.
It is known to use a wide variety of materials, such as ribbed cellulose, cellulose acetate, activated carbon, as filters for cigarettes. These common filter materials are intended to selectively hold back the undesirable and harmful components of cigarette smoke without impairing the taste.
It has now been found that carbon fibers represent a particularly effective filter for cigarettes. The carbon fibers can be used as wadding, woven fabrics and loose felts. Preferably, carbon fibers with a disturbed surface are used, d. H. those fibers whose surface is rough, whose surface has elevations and depressions.
The carbon fibers can u by coking polyacrylonitrile, cotton, regenerated cellulose. a. getting produced. Carbon fibers are preferably used which are obtained from the coking of polyacrylonitrile or cotton.
The carbon fibers can be used alone as filter material; but they are advantageously used in combination with other filter materials, e.g. B. geripp system pulp, cellulose acetate, is used. The part facing the mouth will expediently consist of ribbed cellulose or cellulose acetate.
The table below shows comparative tests of the filters according to the invention with conventional filters. The type and amount of tobacco consumed were always the same, as were the physical conditions (temperature, humidity).
