Improvements in the Finishing of Cotton Goods.
I, MILTON SHERIDAN SHARP, of Orchard Dye Works, Heckmondwike, in the
County of York, Dyer and Finisher, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the finishing of cotton goods especially
cotton Italians, whereby an appearance is produced upon the goods greatly superior
to that obtained by any process hitherto practised or known. The finish produced
by my improved process is permanent, and gives the goods a silk-like appearance
not hitherto attainable.
According to my present invention, the goods upon which it is desired to produce
the above-mentioned novel finish are treated as follows. The goods after being
finished by all or any of the ways of glazing ordinarily used, whether by pressing,
callendering, or embossing, are folded between folds of very damp or wet cloths,
so that the surface of the goods upon which it is desired to produce the above-
mentioned novel finish, is completely covered by very damp or wet cloth. The
goods so folded are put into a steam heated press of the ordinary construction in
the usual way, and are there subjected to heat and pressure. The pressure applied
varies with the length and thickness of the goods under treatment, and may
accordingly be from 5 cwts. to 3 tons as measured by the hydraulic pressure gauge.
The goods are so subjected to heat and pressure for about an hour. I find that not
only is the employment of a degree of moisture largely in excess of that which is
customarily employed in finishing cotton goods, instrumental in effecting the
above-mentioned novel finish, but also that the use of a temperature higher than
that which is usually adopted in finishing such goods is advantageous in effecting
the said novel finish.
I have adopted the method which I have described above, of applying moisture
to the goods, and which at least for the purpose indicated I believe to be entirely
novel, by reason of the fact that the same is a most advantageous way of applying
to the goods the requisite degree of moisture, and further, because I have found
that if the goods be moistened to the requisite degree, and press papers or other
appliance usually employed for such purpose, to be used to separate the folds of
the goods while in the press, such press paper or other appliance hitherto employed,
becomes, after once or twice using, incapable of being further used for such
purpose.
My present invention is applicable to cotton goods generally, including cotton
Italians, and whether the same have been dyed fast black or otherwise dyed.

I, MILTON SHERIDAN SHARP, of Orchard Dye Works, Heckmondwike, in the
County of York, Dyer and Finisher, do hereby declare the nature of this inven-
tion 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 improvements in the finishing of cotton goods, especially
of the class. known as cotton Italians, whereby an appearance is produced upon
the goods greatly superior to that obtained by any process hitherto practised or
known. The finish produced by my improved process is permanent, and gives
the goods a silk-like appearance not hitherto attainable.
According to my present invention, the goods upon which it is desired to produce
the above mentioned novel and permanent finish are treated as follows. The goods
after being finished by all or any of the ways of glazing ordinarily used, whether
by pressing, callendering or embossing, are then folded between folds of very damp
or wet cloths so that the surface of the goods upon which it is desired to produce the
above mentioned novel finish is completely covered by cloth uniformly damped.
The goods so folded are put into a steam heated press of the ordinary construction
in the usual way, and there subjected to heat and pressure. The pressure applied
varies with the length and thickness of the goods under treatment, and may
accordingly be from 5 cwts. to 3 tons to the square inch as measured by the
hydraulic pressure gauge. The goods are so subjected to heat and pressure for
about an hour.
I have adopted the method described above, of applying moisture to the goods
and which at least for the purpose indicated is entirely novel, by reason of the
fact that the same is a most advantageous way of applying to the goods the requisite
degree of moisture, and further because I have found that if the goods upon which
it is desired to produce a permanent lustrous finish be moistened to the requisite
degree, and press papers or other appliance usually employed for the purpose of
finishing are used to separate the folds of the goods while in the press, such press
paper or other appliance hitherto employed, becomes in a very short time useless
in consequence of the same rotting and cracking, by which the goods undergoing
the operation of finishing are spotted or otherwise marked, which is entirely avoided
by the introduction of a uniformly damped cloth folded along with the goods to
be finished.
The material of the damp cloth used along with the fabric to be finished is of
cotton, from which all grease, sizing or other foreign matter must be removed,
and in order to damp the cloth thoroughly and uniformly, I pass the same between
rollers under pressure, one of the rollers revolving in water, from which the water
is transferred to the cloth, or, the cloth may be immersed in water and then placed
in a hydro extractor until the required amount of moisture is obtained.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The fixing of the lustre on cotton goods by first obtaining lustre in any of the
ordinary methods and afterwards folding the cloth along with a cloth uniformly

as herein before described.
