or Unbleached Cotton Warps or Warp Yarns prior to
Weaving.
I, THOMAS PICKLES, of Burnley, Lancashire; Manufacturer, do hereby declare
the nature of my invention for "IMPROVEMENTS IN THE TREATMENT OR PREPARA-
TION OF GREY OR UNBLEACHED COTTON WARPS, OR WARP YARNS, PRIOR TO
WEAVING" to be as follows:-
The improvements relate to the treatment or preparation of grey or unbleached
cotton warps, or warp yarns, intended to be employed in the manufacture of certain
special fabrics, to wit, those fabrics known in the trade as Egyptian Scryms,
Unions, and Arabian Stripes, which treatment or preparation of warps or warp
yarns is effected prior to the same being woven into cloth. And have for object
the causing of the cloth thus woven to take the colour of dye in certain foreign
native dyeing operations more readily than is the case at present, and forms a
modification of an invention for which I have already applied for Letters Patent
numbered 12992 and dated October 29th 1885.
To accomplish this and to effect my improvements, I subject the yarn composing
the cotton warp intended to be woven into Scryms, Unions, or Arabian Stripes, or
such portions of such yarn as are unbleached or in the grey state, to a special
preparation prior to the act of sizing and weaving of such yarn.
This preparation consists of a process of boiling in an open or closed vessel, or
subjection to the action of steam in a closed vessel, for such length of time as iš
necessary to produce the desired effect. The result being that the fibres of the
yarn are opened, separated, or softened, to an extent which renders them more
suitable upon subsequent sizing for the manufacture of the special and particular
goods referred to.
The boiling process may be supplemented or not with special mordanting, as set
forth. in my specification number 12992 of 1885, or with any other means of
mordanting without departing from the peculiarity of this my present invention,
which consists in the application of a boiling process or the application of steaming

page_text: to grey or unbleached cotton warps, whether in ball form, or on beams, or
otherwise, or the yarn for the same, prior to the ordinary sizing process, and
previous to weaving, when such warps or warp yarns are to be employed in the
manufacture of certain special cloths or fabrics as beforenamed, that is to say,-
Egyptian Scryms, Unions, and Arabian Stripes, whether in combination with any
mordanting process or not.
Improvements in the Treatment or Preparation of Grey

I, THOMAS PICKLES, of Burnley, Lancashire, Manufacturer do hereby declare the
nature of my invention for IMPROVEMENTS IN THE TREATMENT OR PREPARATION I
OF GREY OR UNBLEACHED COTTON WARPS, OR WARP YARNS, PRIOR TO WEAVING,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
The improvements relate to the treatment or preparation of grey or unbleached
cotton warps or warp yarns, intended to be employed in the manufacture of certain 2
special fabrics known in the trade as Egyptian Scryms, Unions, and Arabian Stripes,
which treatment or preparation of warps or warp yarns is effected prior to the same
being woven into cloth. And have for object the causing the cloth woven there-
from to take the colour of the dye in certain foreign native dyeing operations more
readily than is the case at present,
To accomplish this and to effect my improvements I subject the yarn composing
the cotton warp intended to be woven into Scryms, Unions, or Arabian Stripes, or
such portions of such yarns as are unbleached or in the grey state, to a special
preparation prior to the act of sizing and weaving of such yarn.

This preparation consists of a process of boiling in an open or closed vessel, or 8
subjection to the action of steam in a closed vessel, for such length of time as is
necessary to produce the desired effect. The result being that the fibres of the
yarn are opened, separated or softened, to an extent which renders them more
suitable, upon subsequent sixing, for the manufacture of the special and particular
goods referred to,

other means of mordanting, without departing from the peculiar character of the
invention.
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 application of a boiling or steaming process to grey or unbleached cotton
warps, whether in ball form or on beams, or otherwise, or the yarn for the same,
prior to the ordinary sizing process, and previous to weaving, when such warps or.
warp yarns are to be employed in the manufacture of certain special cloths or
fabrics, that is to say, Egyptian Scryms, Unions, and Arabian Stripes, whether in
combination with any mordanting process or not, substantially as herein described.
