sidestream TPM collection procedure. Correlation of the two sets of results was excellent. The
values Ecusta obtains for sidestream reduction are about 2/3 of the values we obtain.
Cigarettes have been requested in Semiworks for mechanistic studies of magnesium
containing papers.
A study was completed in the hand sheet lab to determine if drainage times for
magnesium carbonate fillers could be predicted by the amount of material centrifuged down
from an aqueous slurry in a given period of time. Such a correlation was indeed shown to exist.
This provides us with a screening tool to investigate whether or not fillers will have
unacceptable long drainage times.
Project Tomorrow
The second trial run of the "daubing dandy" at the University of Maine took place last
week. Attempts to use a more viscous cellulose slurry in order to obtain well-defined bands
were not successful. The short distance between the "daubing dandy" and the couch roll did
not allow for sufficient drainage, and the still wet web continually wound itself around the first
press roll. When the cellulose level was cut in half, paper was made successfully. However,
band definition was not sufficient. The last attempt utilized a 2% microcrystalline cellulose as
the feedstock. Drainage time was adequate for this material, and a considerable amount of
paper was run. Band spreading still occurred; however, the resulting paper was clearly banded.
For the next trial a second shell will be made with 2 mm instead of 5 mm slits. This change
will lead to less band spreading. Work will be carried out in the hand sheet lab in order to find
a material which will increase slurry viscosity without increasing drainage time. Lastly,
attempts will be made to increase the distance between the dandy and the couch roll in order to
allow for longer drainage time.
PM Web
The patent specification from James River describing their proprietary cellulose acetate
web has been requested and will be sent.
We have located a Forest Products Laboratory in Madison, Wisconsin, which has
considerable experience in the acetylation of cellulose webs as well as cellulose pulps. They
have indicated that they would be quite willing to work with us on collaborative projects. We
are being sent a number of reprints and reports. Once we have looked these over, we will
negotiate a secrecy agreement, and visit the laboratory to discuss what they can do for us.
