the dupont Dye Plant, az Deep Water
Point, N J.-,yhuc.. has established a
technical laboratory for the study of
problems relating to the applications
of dyestuffs.
This laboratory, tcg Their with its
equipment, has been designed in ac-
cordance with the latest advances in
modern science and technique. 1t con-
tains laboratories for the dyeing of
textiles, paper and leather, for calico
printing and for lake making an ex-
perimel.tal dychouse and a very COM
plete and up-to-date library.
The establishment of this technical
laboratory for the purpose of safe
guarding the interests OF dye consum-
ers is an indication of how thoroughly
the synthetic color industry is being
built up in this country.
A common service function of a
technical laboratory is to help the con-
sumner work out his coloring problems.
When he requires shades to be match
ed on his goods in various stages of
their manufacture and in using a spec
ial type of machine for dyeing the
goods, the laboratory makes trial tests
on samples of his material thru a
dyeing machine which is a model of
his own factory equipment. The So
luton of the problem thus worked out
is then submitted to the consumer.
The new technical laboratory at Dee
Water Point is an imposing structure
of ornamental pressed brick, 200 feet
long and 80 feet deep, equipped with a
steam heating plant, two systems for
air ventilation and air publication for
the large laboratories, besides the
necessary gas, water, steam, compress
ed air and vacuum lines.
The main floor contains the execu-
tive Offices, library, restrooms, locker
rooms and showers for employees.
Here, also are offices for the use
of visiting statesmen, who review
the work of the laboratory at reg
ular intervals to become better &C
quainted with the new products as
they are developed.
At the northern end of this floor is
a spacious, well-lighted room, equipped
with power-winding machines for
yarns. In this room operators pre-
pare, wind and accurately weigh the
yarns used for dye testing. They also
make the small bows of yarn used on
sample cards. AS soon as all the nee
essary machinery is installed complete
sample cards will be manufactured in
this department.
At the southern end of the corridor
is the analytical laboratory, with facil-
tiles for identifying unknown dyes n
for determining various chemical prop
critics Of dyestuffs not included IN the
work of the d~ye-testing laboratories:
The laboratory operations and equip
ment on the upper floor are more in
teresting to the visitor. He is likely
to notice first that the architects have
provided abundant air space; each
room. except for glass partitions, ten
feet high. separating it from commune
eating rooms, is open to the roof, al
fording necessary ventilation Tor the
chemists who r conducting their
tests with heat and steam.
A large laboratory at the northern
end of the floor is devoted to dye
testing. Definite amounts OF dyestuffs
are applied to 10-gram skeins, Inc OPP
erations being conducted in small por-
ceIain, glass or enameled cups or
beakers. The beakers are uniformly
heated in specially designed ovens n
when the dyeings are finished the
skeins are dried in a large hot air oven.
Each worker has his W table space
and desk, and devotes his attention
wholly to the testing operations.
The chemists in charge have their
office in a readily accessible Dom adj
Joining the laboratory. This enables
them to supervise closely all dye-test-
ing operations.
a few steps down the corridor on the
west side is the paper
eouipped with miniature heaters, dr1erS
and a line of ~stirrers for beating small
fest lots of paper pulp, and SUCTION
screens for converting this pulp INTO
sheets of D Samples of this paper
are accurately matched for color SO
that the paper manufacturer may have
a definite idea of how he can utilize
dupont dvestufs in his mill. Later on
q larger beater and a 2O-inch paper
machine will be installed in the oase-
ment, and will be operated
