Improvements relating to Printing Plush or Plush like Material.
I, FRANZ WILHELM KESSELER, of Crefeld, Prussia, Engraver, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Hitherto the process followed in the printing of plush and plush like materials has
been based upon similar conditions to those applying in the case of ordinary textile
material or web not having a nap hence it follows that the surface only of plush
became printed whereas the plush or plush like material should be dyed throughout
the entire depth of its nap.
Now in the improved process according to my Invention 1 am enabled to ensure that
that the printing shall be effected, at one operation, of one pattern in as many colours
as may be desired and at the same time I am enabled to effect the dyeing of the
material throughout the whole or at all events nearly the whole of its depth of its nap.
In carrying out my Invention, the the patterns to be printed are engraved on metal
plates or rollers in such a manner that the entire pattern is on one plate or roller and
is engraved upon the plate or roller according to the pattern desired to be printed
upon the web of plush or plush like material, such for instance, as leaf ribs and veins,
without any regard to colour and as deep as corresponds to the depth of the nap.
The plates or rollers thus engraved are dyed in the following way:-Oil colours prepared
in the usual manner are heated and then mixed with tallow or other fatty substance ;
the coloured pattern is composed with these warm colours by putting them in the
required places on the engraved plate or roller; the conductivity of the metallic roller
or plate withdraws the warmth from the colours, and said colours congeal immediately
owing to the influence of the tallow or like substance mixed therewith. After thus
placing all the colours, the roller or plate is heated slightly; this causes the colours to
soften a little and they then run closely together leaving no intervening spaces or
hollows.
nap of
By means of these plates or rollers above referred to, the printing is done by placing
them over the plush or plush like material to be printed without pressure: the
such material, sucks the colour from off the plate or roller and thus becomes dyed.
In the case of using rollers, the material should be placed under them, using no
pressure, and the roller may travel over the material or vice versa.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First In the printing of plush or plush like material the use of rollers or plates
on which the pattern to be printed is engraved in depth equal to the depth of the nap
of the material to be printed substantially as described.
Second-The mixing of the necessary colours with tallow or like fatty substance
and the mode of applying them while warm to the face of the engraved plate or roller
and of again warming slightly the plate or roller and colours substantially as and for
the purposes described.
Third-The mode of printing the plush or plush like material by placing the plate
or roller over but not pressed on to such material and causing the roller or plate to
move over the material or vice versa substantially as set forth.
