MADE FROM The PULP OF TREES.
Already Extensively Used-New Material
Costs Less Than Natural silk and IL
Said to Be Beautifui-Invented by q
Swiss.
A process has been discovered by which
material closely resembling silk may DO
manufactured from wood. Even now wo
men are walking about tho streets Of Eu
ropean CITIES In the most elaborate gowns
of silk in the manufacture of which the
worm had no part. In fact, tho silkworm
has lost Its occupation.
The palm for this valuable discovery I'm
chemical science must go to Switzerland,
for native Of Zurich, DIR. Lehncr 10y
name, Is the inventor OF the process.
Some years ago he began To make OBJ
servations on the habits and physical char.
acteristics of the silkworm and became
deeply interested In thu subject He dis.
covered the chemical action which took
place in the worm In producing Its cocoon
and at odd times sought to counterfeit the
work Of nature. So convinced did he be
come Of the feasibility Of his ideas that he
soon abandoned all other work and devot.
ed his time to this single study, in which
he has achieved II signal triumph
In the process Of manufacturing the new
fabric the principal ingredients used are
spruce wood pulp, cotton or jute waste,
etc, combined with large quantity OF al.
cohol. The use Of the substantial or solid
materials mentioned creates n market foi

for this as well as the other materials are
digested by chemical process in which al.
cohol plays an important part. The mate
rial thus digestod is so much like the co.
coon spun by the silkworm that when the
two are placed side by side in finished
state it takes an expert to determine which
Is which.
The artificial material Mt one state Is In
a liquid state, and of density about
equal to the ordinary sirup of commerce.
When in this state, machine Of DIR. Leh.
ner's invention, which may DO called an
artificial silkworm, comes into play. This
machine, which is very simple in construc.
tion, requiring so little attention that II
can be kept at work with about as much
labor as is devoted to "a hour clock, per.
forms exactly the same mechanical work
that silkworm does. 1t draws from the
liquid q continuous, unbroken thread of
even diameter and unlimited length. AS
this thread is spun another portion of the
machine takes it up and twists it into any
desired thickness of yarn with perfect reg.
ularity.
Thus the fabric can be made Of any de.
sired weight or thickness SO that it will
be seasonable at all times
This artificial silk has been spun in
Il s..xe
large variety of fabrics. In the dyeing,
weaving and finishing of these no special
treatment has been found necessary. 1t
has been dyed in all imaginable shades and
colors, and owing to the peculiar qualities
of the material 1t takes dye more readily
and gives more brilliant effect than the
natural article. In texture it Is the equal
of the best of Chinese and Italian silks,
being soft and silkcn to the touch 1t Is
expected that it will be used largely in
combination with natural silk and cotton
for producing brocaded effects. These lat
ter have been so expensive lately as to be
out of reach OF all but the fattest purses.
The new invention will greatly reduce the
cost.
1t would seem that this new process
would give an immense impetus to the
manufacture Of textile fabrics all over the
world, and it probably will, but DR. Leh
ner also differs from the average inventor
in that he combines financial cunning
with his remarkable genius, SO that every
yard of this new material made will put SO
many pennies into his pocket.
Patents on the process have been OBJ
tanned in most Of the European countries,
and an application for one in the United
States is now on file at Washington, as
well as in the patent office of the Canadian
government A company with capital
stock of 81, 800, 900 is about to be formed
in Montreal to manufacture the material.
There has already been formed in England
company having capital stock of $780,
600, the inventor receiving $160,000 in
cash and $3.50, 900 in full paid shares, the
remaining 5000, 900 being used as a work
ing capital.
1t was originally intended to manufac-
ture the article in England, but when the
demonstrating plant was established at
Bradford it was found that there was q
prohibitive tariff on alcohol used for man
ufacturing purposes. For that reason the
plant was located at Glattburg, near Eur
ich, Germany, where there is no tax on al.
Cohol used in manufactures. From this
place the raw material Is sent to England
for manufacture York World.
