COMPLETE SPECIFICATION.
The Manufacture of a Decorative Material suitable for Paper-
hangings and other purposes.
I, LOUIS DANOIS, of 8 Rue Erard, Paris, France, Manufacturer, do hereby.
declare the nature of this invention and in what manner the same is to be per-.
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-
The purpose of my invention is to create, in the wall paper trade, a novel;
material for wall papers imitating silk, damask, velvet or the like, and which I call
"Plush paper hangings." I obtain this novel material by employing, with the used
and known processes in the trade, the following combination.
1. I take a surah ground, or a bronze ground, of the tint of the stuff to be
imitated, be it a light pink, sky-blue, reseda, or other shade. This surah ground,
or bronze ground, which is manufactured in the ordinary and well known manner in
the trade, is preferably one that has undergone a calendering, and has had a.
grained texture imparted thereto.
2. Upon this prepared ground I print the pattern, or border, in a tinted size,'
by means of a block or plate upon which is engraved in relief the pattern I wish to
produce upon the surah or bronze ground; the shade of the tinted size being the.
same as that of the silk which will be applied in a subsequent operation.
3. The size thus printed and dry, I print for the second time, and over this size,
and still with the same engraved pattern or border block, a mordant composed of
boiled fat-oil and white lead, and which is the ordinary mordant used in the wall
paper trade.
4. The pattern, or border, having been printed in this mordant, the roll of
papering is passed through an ordinary velveting-drum, then, by means of a sieve
I sprinkle, upon the roll, silk flock tinted to the shade of the surah or bronze ground
and generally, and by preference, of lighter shade thereof. I then drape the
papering by the means now in use in the trade.
This silk flock is applied to all the parts printed with the mordant, and the
papering thus printed is stretched upon the usual frames.
5. About an hour after these rolls of hangings have dried, they are unrolled
upon a flat table, and by means of the softest possible brush (by preference a
badger's hair brush), I brush, by hand, or mechanically, the silk flock, laying it
down lightly and in the vertical direction of the pattern, that is to say from left to
right. So soon as this operation is effected the appearance of the silk flock changes,
it becomes brilliant and immediately gives the reflection of plush, light and dark;
an effect hitherto unknown in the wall paper trade.
6. By this process, employing always the same material—silk flock—I can also
produce a plain plush. For this purpose I proceed as follows:-
I take a roll, or a panel, of the size to be manufactured, and lay on the ground
the shade to be executed. This ground is then sized, and as soon as the size is dry,
the entire surface is covered with a mordant composed as in paragraph 3, and I

passing through the velveting-drum and sprinkling on, by means of a sieve, the
silk flock. These hangings are then allowed to dry for about an hour. After this
delay the hangings, or panels, are unrolled upon a table, as in paragraph 5, and
always employing a soft brush (preferably a badgers' hair brush) the silk flock is
lightly laid down, but in a different manner to that indicated in paragraph 5, that
is to say, in order to obtain varied reflections for the plush paper-hangings, instead
of brushing in a vertical direction, the brushing is performed in a circular direction.
In this manner I obtain the varied reflections and brilliancies which are produced
by plush, and by employing, for the first time, silk flock, combined as above
stated, I obtain these novel materials-plush paper-hangings for apartments-
either plain or with a pattern, which is a great improvement in the manufacture of
wall papers.
I can also employ hot or cold stamping with these plush paper-hangings for
apartments, so that the silk flock may be either depressed, or be in relief, and this
by means of engraved blocks or cylinders either sunk, or in relief, combined
with one or more colored bronzes, gilding, leaves or powder; the whole being
stamped by a fly-press or by a cylinder in the manner now practiced in the
trade.
.
7. By the same process I can also reproduce plush stuffs with different reflections™
and colors by employing several successive impressions each of which is effected in
the manner stated in paragraphs 2, 3 and 4.
The material or product manufactured according to this invention, that is to say
silk flock brushed in a circular direction after its application so as to produce the
varied reflections of plush, can also be employed, at a much less cost than real
plush, for wearing apparel, such as hats for men or women, or for dresses.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture of a decorative material suitable for paper-hangings and
other purposes, in which silk flock is employed to produce plush-like effects, sub-
stantially as hereinbefore described.
2. The novel material produced in the manner substantially as hereinbefore
described.
