A. NEW MEANS OR METHOD OF PRODUCING A PERMANENT DESIGN UPON RAISED PILE FABRICS, OR. WOVEN PILE.FABRICS
Year: 1884

page_text: I, THOMAS WHITHAM, of the firm of Whitham, Kropff. and Company, of St Paul's
Street Leeds, in the County of York, Woollen Merchants do hereby declare the
nature of my said invention for "A. NEW MEANS OR METHOD OF PRODUCING A
PERMANENT DESIGN UPON RAISED PILE FABRICS, OR. WOVEN PILE.FABRICS "_to be
as follows:-
This Invention has reference to a new means or method of producing a per-
manent embossed design upon woven pile or raised pile fabrics.
Hitherto designs have been embossed upon such fabrics produced by heat and
pressure only, but in practice it is found that the design so made, can easily.be
erased either by moisture, wet, friction, or stretching of the fabric.
The object of my Invention is to emboss or produce a permanent design upon
such fabrics, which cannot be erased, as is the case with designs produced in the
present manner.
To carry out my Invention I arrange that the design intended to stand above
the surface of the fabric, shall be depressed or sunk by pressure, below the surface
of the fabric, leaving the ground-work of the fabric above the surface. The fabric
is afterwards passed through a cropping or shearing machine, which shears off the
ground-work, or what is for the time. being, the elevated. part of the, fabric.
After the fabric has been thus sheared, it is steamed or immersed in water, (by
preference) hot water, which causes the depressed or sunken part of the fabric to
rise up again, consequently the pattern which was depressed is now elevated above
the surface, and can neither be erased by moisture, friction, or stretching of the
piece, by which means patterns can be cheaply and expeditiously produced upon
pile or raised fabrics whether woven or felted.

I, THOMAS WHITHAM of the firm of Whitham, Kropff and Company of St Paul's
Street, Leeds in the County of York, Woollen Merchants, do hereby declare the
nature of my invention for "A NEW MEANS OR METHOD OF PRODUCING A
"
PERMANENT DESIGN UPON RAISED PILE FABRICS OR WOVEN PILE FABRICS and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has reference to a new means or method of producing a per-
manent embossed design upon woven pile, or raised pile fabrics."
Hitherto designs have been embossed upon such fabrics by heat and pressure
only; but in practice it is found that the design so made can easily be erased,
either by moisture, friction or stretching of the fabric.
The object of my invention is to emboss or produce a permanent design upon
such fabrics, which cannot be erased as is the case with designs produced in the
present manner.
To carry out my invention I arrange that the design intended to stand above
the surface of the fabric shall first be depressed or sunk by pressure below the
surface of the fabric, leaving what will have to be the ground work of the fabric
above the surface.
After the fabric has been thus embossed it is passed through a cropping or
shearing machine, which shears off the ground work, or what is for the time being
the elevated part of the fabric.
After the fabric has been sheared, it is steamed or immersed in water, (by
preference) hot water, which causes the depressed or sunken part of the fabric to
rise up again, consequently the pattern which was depressed is now elevated above
the surface, and can neither be erased by moisture, friction or stretching of the
piece, by which means patterns can be cheaply and expeditiously produced upon pile
or raised fabrics, whether woven or felted.
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;
The production of designs upon raised or woven pile fabrics by pressing down
the pattern, and shearing off the ground work, in manner substantially as herein
described.
Dated this 3rd day of December 1884.
