Papermaking
BAGASSE.--Bagasse, or the refuse sugar-cane, is given rather scant
consideration in the Government report. Its individual fibers are
short, and the percentage of pith is large. Several small plants have
had discouraging experiences in attempting to put this material to
commercial use. Nevertheless, recent experiments carried on in the
interests of the United Fruit Company, under the Simmons patents, point
to a promising result. Under this process the cane is not treated in
the usual manner of crushing for the extraction of sugar. Instead, it
is shredded, dried, and the pith separated from the fiber. The product
is then shipped in bales to refineries, where the sugar is extracted.
This method is said to achieve an almost complete extraction of the
sugar, whereas the old method of crushing loses about twenty per cent
of the sugar and injures the fibers. The Simmons process does no
damage to the fibers, which though short, possess excellent felting
properties. The pith, being cellulose of a non-fibrous structure, has a
value for other industries than paper-making.
FLAX STRAW.--There is an abundant annual crop of flax straw. The
average yield per acre is about one ton, and the total annual
production about 3,000,000 tons. In the opinion of the Government
investigators, it is a “most promising” material.
There are practical pulp men who deprecate the findings of the Bureau
of Plant Industry. Martin L. Griffin, chemist to the Oxford Paper
Company, of Rumford, Maine, in an article appearing in Volume XI, No.
2, of _Paper_ for March, 1913, makes the following statement:
“There is a popular view, which has been erroneously fostered by the
Government, that there are exhaustless resources of waste fiber in our
country, suitable for paper, and a substitute for wood. I once thought
so myself. It is very natural to think that the discarded stalks of
sugar-cane, corn, cotton, rice, flax, and other plants, which mature
annually, would prove an abundant substitute for wood.
“These have all been exploited for twenty-five years to my personal
knowledge, with no visible results. A plant has one function to
perform--it is to flower, fruit or make stalk. Its other functions are
subordinate and produce only by-products. The stalk is the main product
of the forest tree. No other fibrous material is so rich in cellulose;
no other which lends itself so easily to paper-mill processing. It has
no seasons of harvest; does not require curing; does not easily decay;
requires no packing, and may be stored best in the rivers. All these
waste stalks are pithy, bulky and perishable, and would require much
labor to gather, pack and ship. These are but a few reasons why we may
expect no practical results from this source. Wood fills a place no
other material can. There is no substitute for it.”
