I, GEORGE GRANDAGE, of Thorn Bank, Bradford, in the County of York,
Dyer and Finisher, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the production of ornamental effects upon textile
fabrics, in particular to what is known as a moiré effect, and although the
invention may be applied to actual silk goods, it is particularly applicable to
goods of a commoner nature, such for example as cotton, union or woollen
goods.
In carrying out the invention I subject the fabric to be treated to the opera-
tion of one or more rollers under suitable pressure and with or without heat or
moisture. The rollers are engraved with very fine lines or ribs which may run
straight across or diagonal or at any desired angle to the axis of the roller and
may be spirally arranged if desired.
At the
Good results are obtained with the lines lying parallel to each other, but they
may cross each other if desired in which case a single passage of the fabric
through or between the rollers may be sufficient. Usually however I find it
desirable to pass the fabric two or more times through the rollers.
second pass the lines or marks formed in or upon the fabric do not coincide
with those made at the first pass and a moiré or other irregular pattern or effect
is produced.
To obviate the necessity for passing the fabric more than once through the
machine I may supply it with more than one roller or more than one pair of
rollers, so set as to produce the desired result; the rollers may be geared
together or not as required, or I may employ two machines in series, the fabric
going from one machine to the next so that both machines would be working
upon the fabric at the same time. However two or more entirely independent
machines may be used.
With certain qualities of goods I also obtain similar effects by first passing
through rollers at least one of which is very finely engraved or scored with ribs
and afterwards pressing in an ordinary hydraulic steam press also by first pass-
ing through the rollers and then placing two pieces together face to face for a
second passage through the machine.
Though I do not bind myself in any way as to the size of the grooves and
ridges or the distance between them, I have so far obtained the best results with
the employment of extremely fine lines.

I, GEORGE GRANDAGE, of Thorn Bank, Bradford, in the County of York,
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: _

This invention relates to the production of ornamental effects upon textile
fabrics, in particular to what is known as a moiré "watered" silk or equivalent
effect, and although the invention may be applied to actual silk goods, it is
particularly applicable to goods of a commoner nature, such for example is
cotton, union or woollen goods.
In carrying out the invention I subject the fabric to be treated under suit-
able pressure and tension and with or without heat or moisture to the opera-
tion of one or more rollers. One or more of the rollers are engraved with very
fine lines or ribs which may run straight across or diagonal or at any desired
angle to the axis of the roller and may be spirally arranged if desired. The
fabric should be strained or stretched during the passage through the rollers
and the rollers may bear a distinct figure or pattern (similar to that of an
ordinary embossing roller) in addition to the fine lines, the moiré effect thus
obtained being much more regular and distinct than when straight lines only
are used.
Good results are obtained with the lines lying parallel to each other, but they
may cross each other if desired in which case a single passage of the fabric
through or between the rollers may be sufficient. Usually however I find it
desirable to pass the fabric two or more times through the rollers. At the
second pass the lines or marks formed in or upon the fabric do not coincide with
those made at the first pass and a moiré or other irregular pattern or effect
is produced.
To obviate the necessity for passing the fabric more than once through the
machine I may supply it with more than one roller or more than one pair of
rollers, so set as to produce the desired result; the rollers may be geared
together or not as required, or I may employ two machines in series, the fabric
going from one machine to the next so that both machines would be working
upon the fabric at the same time. However two or more entirely independent
machines may be used.
With certain qualities of goods I also obtain similar effects by first passing
through rollers at least one of which is very finely engraved or scored with rihs
and afterwards pressing in an ordinary hydraulic steam press, also by first
passing through the rollers and then placing two pieces together face to face for a
second passage through the machine.
Though I do not bind myself in any way as to the size of the grooves and
ridges or the distance between them, I have so far obtained the best results
with the employment of extremely fine lines, as many as from 15 to 40 to the
millimetre having been satisfactorily used.
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. Producing an ornamental effect of the kind and in the manner described

page_text: upon textile fabrics by passing them between rollers such as are hereinbefore
specified.
2. Producing a moiré figured effect of the kind and in the manner described
upon textile fabrics by passing them between rollers engraved or scored with
extremely fine parallel lines and a figured or embossed pattern.
3. In the manufacture of textile fabrics passing them successively between
rollers engraved or otherwise marked for the purpose described.
4. In the manufacture of textile fabriés passing them between rollers engraved
or otherwise marked and subsequently pressing them for the purpose described.
5. In the manufacture of textile fabrics passing them between rollers engraved
or otherwise marked placing two pieces of the fabric thus treated face to face
and again passing them between rollers for the purpose described.
