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, Wyckliffe Road, Urmston near Manchester in the same county Salesman
do hereby declare the nature of this invention to be as follows:-
Our said invention relates to certain improved processes and means for ornamenting
cut pile fabrics such fór example as velvets velveteens, corduroys and such fabrics
as cannot conveniently be ornamented by the ordinary process of printing. In
preparing such fabrics for treatment in accordance with our invention we dye them
with such colours as are susceptable of being discharged or modified by the action
of certain discharging or modifying agents which are afterwards applied. To
produce the required pattern or ornamental effect upon the dyed fabric we make
use chiefly of a solution of chloride of lime or ordinary bleaching liquor and apply
it at the required places to the surface of the dyed fabric. The result is that
where-ever the 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. Where an irregular
effect or pattern is required the discharging agent is applied to the surface in the
form of a spray or in splashes and where a design or pattern capable of reproduction
or repetition is desired we prefer to use a revolving roller or revolving rollers
carrying design surfaces in relief which apply the solution to the fabric as it is
moved past the roller. These relief surfaces practically print the design upon the
fabric. The said surfaces are preferably so made and the roller is so adjusted as
not to press too heavily upon the pile. For example the applying surfaces might
be made of felt or other comparatively soft material compound or fabric and be
of a porous nature so that they could be kept saturated with the solution from the
interior of the cylinder or from any other suitable source. In some cases when
producing an irregular or splashed pattern or effect we might also employ a roller
or revolving body which would throw the solution upon the fabric in splashes of
regular or irregular size and we might provide adjusting means for increasing or
diminishing the number and size of the said splashes at pleasure. The strength of
the discharging agent is varied to suit the nature of the dye in the fabric. In
some cases we might add colouring matter to the discharging solution so as to colour
the portions of the fabric affected by the solution, or we might colour the affected
places by an after printing or colouring operation. For example where applying
the solution to the fabric by means of the relief surfaces herein before referred to
we might pass the fabric immediately over a drying cylinder and colour the affected
portions by corresponding reliefs on a succeeding roller. In some cases and
especially where it is wished to obtain patterns or effects by changing or modifying
portions of the dyed fabric we use solutions of sulphurous or other acids. With
certain dyes these acid solutions will when applied by themselves charge one colour
to another and thus produce the desired effect, but in the acid solutions also we
might modify the results by adding colouring matter to the solution. To prevent
blurring or spreading of the discharging or modifying agent or of the subsequently
applied colours we apply heat in any suitable manner for example we pass the
fabric over a heated cylinder or over hot plates so as to rapidly dry off the solution
or fix the colours. In order to produce a multiple effect of a pattern consisting of
spots splashes or patterns of different colours the surface of the fabric may be

thrown on or applied as herein set forth.

. Improvements in Processes 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 1
Lancaster, Merchants, and CHARLES ALEXANDER POTTS of No. 15 Hereford
Grove, Wyckliff Road, Urmston, near Manchester, in the same County, Salesman,
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, that is to say :-
Our said invention relates to certain improved processes and means for
ornamenting cut pile fabrics such for example as velvets, velveteens corduroys and
such fabrics as cannot conveniently be ornamented by the ordinary process of
printing. In preparing such fabrics for treatment in accordance with our invention
we dye them with such colours as are susceptable of being discharged or modified
by the action of certain discharging or modifying agents which are afterwards
applied. To produce the required pattern or ornamental effect upon the dyed
fabric we make use chiefly of a solution of chloride of lime or ordinary bleaching
liquor and apply it at the required places to the surface of the dyed fabric. The
result is that where the 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. Where an
irregular effect or pattern is required the discharging agent is applied to the surface
in the form of a spray or in splashes and where a design or pattern capable of
reproduction or repetition is desired we prefer to use a revolving roller or revolving
rollers carrying design surfaces in relief which apply the solution to the fabric as it
is moved past the roller. These relief surfaces practically print the design upon
the fabric. The said surfaces are preferably so made and the roller is so
adjusted as not to press too heavily upon the pile. For example the applying
surfaces might be made of felt or other comparatively soft material, compound of
fabric and be of a porous nature so that they could be kept saturated with the
solution from the interior of the cylinder or from any other suitable source.
some cases when producing an irregular or splashed pattern or effect we might
also employ a roller or revolving body which would throw the solution upon the
fabric in splashes of regular or irregular size and we might provide adjusting
means for increasing or diminishing the number and size of the said splashes at
pleasure. The strength of the discharging agent is varied to suit the nature of
the dye in the fabric. In some cases we might add colouring matter to the
discharging solution so as to colour the portions of the fabric affected by the
solution. To prevent blurring or spreading of the discharging or modifying
agent we prefer to apply heat in some suitable manner, for example we might

solution or fix the colours.
In
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 :-
The improved mode of ornamenting piled fabrics by dyeing such fabrics and
