COMPLETE SPECIFICATION.
Production of Cloudy or Variegated Effects in Textile Fabrics
Solely by Printing.
I, FRANZ HERMANN SCHNEIDER, Manufacturer, of Mylau, Voigtland, Saxony,
in the Empire of Germany, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
Cloudy or variegated textile fabrics which were formerly manufactured of
watered or tabbied yarn are produced by printing the material and subsequently
washing and milling it.
As these supplementary operations are not suitable for all fabrics which are to
have a cloudy or variegated appearance, the treatment forming the subject of this
invention has been employed, the above-mentioned supplementary operations being
omitted, the cloudy or variegated appearance being produced not less successfully
by means of a printing process only. In order to secure this result, the printing
cylinders are so arranged that two cylinders with engraved patterns thereon operate
one above the other, the engraved patterns having the appearance of being unde-
fined and blended representations, the cylinders having a different working
inclination on account of the effect to be produced by the patterns when they are
printed one over the other, whereas in the printing of variegated or cloudy fabrics
similar to those produced under the present invention, a prior production of the
gound-work is indispensable.
By means of cylinders of the kind mentioned, a cloudy or variegated effect is
produced, which is least equal to that effected in the ordinary manner with
textile fabrics the process being capable of employment for every conceivable
kind of woven material, whereas, in the treatment by "raising" and the corre
sponding operations, the nature and composition of the material has to be carefully
considered.
The method of production is explained by means of the annexed illustrations:
Fig. 1 is an illustration of an imprint of a cylinder the direction being from
right to left.
Fig. 2 an illustration of an imprint from an opposite cylinder, the direction
being upwards from right to left.
If looked at front-ways, neither of these imprints will show any clear working
stripe, such being only visible if Fig. 1 be viewed from the left-hand side and
Fig. from the right.
Fig. 3 illustrates a printing effected by the two rollers one over the other, and
Fig. 4 a piece of material in the manner claimed under the invention, by the
two rollers engraved in the manner illustrated by means of the drawing Fig. 1
and 2 and in which the blended effect of the imprint through the nap of the
material is more striking than the piece of cloth supposed to be printed by a single
cylinder as in Fig. 1 and 2; and from this the complete success of the variegating
or cloudy effect producing operation is made perfectly clear under this process.

page_text: If the printing is to be effected on a coloured ground work, the ground is also
produced by printing, in order to obviate the trouble connected with the dyeing
process.
This is effected by means of a cylinder the engraving of which Fig. 5 is so fine
that the drawing is not to be distinguished in print with the naked eye and appears
in the material Fig. 6 completely as a coloured or dyed ground.
By this method of treatment the producing of a variegated or cloudy effect
in the material is made exceedingly simple and capable of being carried out in
connection with all kinds of woven material.
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
1. In the production of variegated or cloudy fabrics by printing, and for dis-
pensing with the subsequent further "textile" treatment, a method of treatment
in which printing cylinders are employed, these cylinders being engraved with
patterns in such a manner that the patterns appear, in print, like undefined
blended representations.
2. In the production with coloured ground-work of the variegated or cloudy
textile fabrics as referred to in Claim 1, the forming of the ground-work by
printing the material with a cylinder, so finely engraved, that the drawing is
indistinguishable in the print, with the naked eye.
