Improvements in the Method of and Means for Ornamenting Piled
Fabrics.
We JOHN MADDOCKS WALKER and JOHN THOMAS REYNOLDS of the firm of
J. M. Walker and Co. of 29 Mosley Street, Manchester, in the County of Lancaster,
Merchants, and CHARLES ALEXANDER POTTS of No. 15 Hereford Grove,
Wyckliff Road, Urmston near Manchester, aforesaid, Salesman do hereby declare
the nature of this invention to be as follows:-
Our said invention relates to an improved method of ornamenting piled fabrics
such for example as velvets, velveteens, corduroys and similar fabrics.
In preparing such fabrics for treatment in accordance with our invention we dye
them in such colours as are capable of being discharged or modified by the action
of certain discharging or modifying agents which are afterwards applied. The said
discharging or modifying agent consists generally speaking of a solution of chloride
of lime or ordinary bleaching liquor, or any suitable discharging agent, which is
applied at the required places to the surface of the dyed fabric.
The result is that wherever the dyed fabric is touched by the solution the dye is
discharged or it might be modified and a pattern or effect is produced on the piece.
This application of the solution to the dyed fabric is effected in any suitable
manner, for example the discharging fluid may be printed on the piece by a printing
roller or rollers where a design is required, or it may be thrown on in the form of
sprays or splashes where an irregular effect is sought for. The piece thus treated
with discharging solution is then painted or "topped" in the ordinary manner the
colour used to paint or "top" the fabric, colouring or modifying the discharged
pattern or splashes. For example suppose we wished to produce a velvet having a
dark blue ground and lighter blue ornaments. The velvet is first dyed black and
the pattern is then printed thereon in discharge solution.
We then take a lighter navy blue and paint or "top "the whole surface of the
piece, with the result that the black ground is modified to a dark blue and the
discharged ornaments show in lighter navy blue upon the velvet.
66
By varying the painting or topping" medium and by the use of colours in
unison with the discharging solutions various effects may be produced as will be
evident to practical colour printers and dyers.
Instead of discharging the pattern from the dyed fabric as herein set forth, we
might before dyeing print the pattern in medium which will resist the dye.
When the piece is afterwards dyed the pattern so stopped or
"saved" appears
distinct from the ground. The painting or "topping" operation is equally
applicable to fabrics so treated.

COMPLETE SPECIFICATION.
Improvements in the Method of and Means for Ornamenting Piled
Fabrics.
We JOHN MADDOCKS WALKER and JOHN THOMAS REYNOLDS of the firm of
J. M. Walker and Co. of 29 Mosley Street, Manchester, in the County of Lancaster,
Merchants, and CHARLES ALEXANDER POTTS of No. 15 Hereford Grove,
Wyckliff Road, Urmston, near Manchester, aforesaid, Salesman, do hereby declare
the nature of this invention and in what manner the same is to be performed to

page_text: be particularly described and ascertained in and by the following statement that is
to say :-
Our said invention relates to an improved method of ornamenting piled fabrics
such for example as velvets, velveteens, corduroys and similar fabrics.
In preparing such fabrics for treatment in accordance with our invention we dye
them in such colours as are capable of being discharged or modified by the action
of certain discharging or modifying agents which are afterwards applied as for
example in accordance with our previous Patent No. 17276 of 1891. The said
discharging or modifying agent consists generally speaking of a solution of chloride
of lime or ordinary bleaching liquor, or any suitable discharging agent, which is
applied at the required places to the surface of the dyed fabric."
The result is as set forth in our said previous Patent that wherever the dyed
fabric is touched by the solution the dye is discharged or it might be modified and
a pattern or effect is produced on the piece. This application of the solution to the
dyed fabric is effected in any suitable manner, for example the discharging fluid
may be printed on the piece by a printing roller or rollers where a design is
required, or it may be thrown on in the form of spray or splashes where an irregular
effect is sought. According to our present invention the piece thus treated with
discharging solution is then painted or "topped" in the ordinary manner, the colour
used to paint or "top" the fabric colouring and also fixing or modifying the
discharged pattern or splashes together with the ground. For example suppose we
wished to produce a velvet having a dark blue ground and lighter blue ornaments.
The velvet is first dyed black and the pattern or effect is then printed or splashed
thereon in discharge solution. We then take a lighter navy blue and paint or
"top" the whole surface of the piece, with the result that the black ground is
modified to a dark blue and the discharged ornaments or effects show in lighter
navy blue upon the velvet.
By varying the painting or "topping" medium and by the use of colours in
unison with the discharging solutions various effects may be produced as will be
evident to practical colour printers and dyers.
Instead of discharging the pattern from the dyed fabric as herein set forth, we
might before dyeing print the pattern in a medium which will resist the dye.
66
When the piece is afterwards dyed the pattern so stopped or saved appears
distinct from the ground. The painting or "topping" operation is equally
applicable to fabrics so treated.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
Painting or "topping" pile fabrics previously dyed and prepared, treated or
ornamented by suitable dye discharging or dye resisting agents so as to produce
patterns or effects substantially as hereinbefore described and set forth.
