TOBACCO AS A FILTM 1MDIM1 FOR
C1 dA-TfE-T-TEj."-
Extensive tests have been carried out to
investigate the possibility of using finely cut
tobacco
for the manufacture of filter rods for cigarettes.
These tests have shown that the use of such
filters
presents possibilities of importance. Some of the
advantages and attributes of such a filter are:-
(a) Greatly enhanced Tobacco Taste and.
nr e j-Fj-r- c-6-
A criticism of normal filter
material has always been that the
smoke draurn through such a filter is
insipid and tasteless. The rse of
tobacco as a filter material give5 the
smoke considerably greater tobacco
character than that which is il--sed
through a normal filter The nature
of the tobacco used as a filter has a
pronounced influence on the taste.
This fact opens up a large fi -eld of
possibilities: the high grade tobacco
used in the filter tip 1.wy ii.,-rrove the
smoking qualities of a lo,! grale blend
or disguise the unpleasant cbaracter
of some local type of leaf.
Alternatively, the use of Oriental
leaf in the filter tip iri--arts a
pronounced Oriental flavour to the
smoke. It is thus possiblc that it
may be found preferable in blended or
American-tyT~e ci,arettes to use a
'
-
f Oriental to!~7cco
filter tip bade
o
and to omit the usual percentage of
Oriental leaf from the blend. A
large number of combinations may be
tried, such as the use of an Oricntal
filter tip with a Virginia flue-cured'
cigarette, the use of a Virginia flue-
cured tip with a blended cigarette,
the use of a fermented blac', filter
tip with a Virginia or blended
cigarette or vice versa. Ft:rthermorc,
experiments may be uade flavourin- the
tobacco used for the filter rod 'iut
not-necessarily that used in the
cigarette. This vould make it possihie
to experiment vith flavours w'.!ic-i have
an unsuitable arona when ")urnt but -uhi-ch
might affect the snoke J* -n a rleasing
way when used on the tobocco in the tip.

Filter rods made according to these
details may be made on most Cigarette
Making Machines and filter tipped
cigarettes, using these rods, may be
made up on any conventional filter
tipping unit.
In territories where inport
restrictions or lacic of local manu-
facturing facilities make the use of
materials such as cellulose acetate
or crimped paper difficult or expensive
or impossible, this type of filter may
be readily made.
(c) Good Filtration ELJ~iqiejjqy.
This compares favourably -ith a
cellulose acetate filter.of 51100,000
denier of the same length -hen the leaf
tobacco to be used in the filter is
converted into rag at 200 cuts -,:-er inch.
Finer crts increase the filtration
efficiency but at the same time also
increase the dra- resistancc*. For
this reason it way be found that the
optimum cuts to the inch are 20r.
For accertable dra,.! resistance us,.ne
this tobacco, it has been found tliai
the filter rods s-hould have a density
of arproximately .39 9. -,~er cc.
For instance, filter rods measiiring
90 mm. x 25-75 mm. vay be made at
15 to the ounce. The y-aper used
as a wrapper for the filter rods may
be Crompton's Verge .2122.
(d) Attractive. Ap2zeAx:ELnce aq~L.A;kkpLs
The a2pearance of cigarettes riiade
up with a tobacco filter is particularly
attractive when the tobacco used in the
filter is of a sharply contrasting shade
to that used in the cigarette; for
instance, the use of a bright Flue-cured
tip on a blended cigarette. There
would seen to be --iuch score in
advertising such cigarettes; its
enhanced and "full" tobacco taste, its
effective but unobtrusive smoke
filtration, the fact that its conposition
consists entirely of tobacco, are sone
of the points whicli might be used.
