equipment for testing and applying
dye pigments in a practical way.
There are paint grinders, ink grinders,
photographic stones, offset presses,
half-tone presses and all the minor adj
juncts of these industries. With equip
ment of this sort, the technicians in
charge are able to render service of a
high order to any consumer who re-
quests it.
Down the corridor to the southern
end is an experimental dyehouse fitted
with the dyehouse equipment used in
all classes of textile mills-machines
designed to dye loose stock, hosiery,
cops, tops, warps, pieces, yarns, or any
other forms OF materials used in the
textile trades. These machines are
not full size, but are practical working
models, capable of handling, on the
average, ten pounds of material. The
equipment also includes hydro-extrac-
tors and driers. In addition to the
jigs and adding machines, there will
soon be installed two calico printing
machines with steamers, which will
make possible extensive work along
the lines of textile printing.
In the basement are the heavier
pieces of machinery, such as leather
drums, glazing machines, paper beat
ers and a paper machine with its cal
endar rolls, the heating system, the
machinery that supplies the building
with its compressed air and vacuum
service lines, and a Photographic dark
room, equipped with photo-micro-
graphic apparatus and a protector.
Ultraviolet lamps of different types
have also been installed for rapid col
or fading tests.
The entire personnel of the Techni-
cal Laboratory has been carefully
chosen. Each member of the corps
has had long practical experience, to-
gether, with the necessary scientific
training for his particular line of
work. Considering the highly techni-
cal nature of the work and; the range
of problems submitted by the many
consumers of DUPONT dyestuffs it will
be plain that the company has exercis-
ed wise forethought in procuring the
best talent obtainable
A competent staff of demonstrators
regularly call on the trade, and also
keep in close touch with the work OF
the laboratories. In their work in the
field they frequently come upon diff
cult technical problems. In such cases
they return to the laboratory to carry
out special work on these problems
Thus in definite, practical ways the
DUPONT Technical Laboratory is a serv-
ice institution. The company's policy
has always been to make quality pro-
ducts, and to render to its customers a
full measure of service. This labora-
tory has been established the better to
maintain this policy as it relates to
the dupont dyestuffs industry.
No finished dyestuff is offered fol
sale to a customer until it has been
thoroughly Investigated with regard to
its shade, strength, solubility and gen,
eral working qualities. Each product
has it's own standard, or type, and alb
solute conformity to this standard is
required before any lot can be approx
ed for sale. The Technical Labora-
tory is held responsible for the main
tenance of these standards 1t stands
between the plant and the customer
furnishing a service that insures the
high quality demanded alike by the
manufacturer and by the consumer
who uses the dyes.
1t is quite evident that the work OF
this Technical Laboratory, covering as
it does the control of shipments.
matching of customers samples, work
ing out coloring problems and supply
ing advertising matter or information
for salesman and consumer, holds a
place of great Importance in the de-
velopment of the dyestuff industry in
America.
