IMPROVEMENTS RELATING TO THE SIZING OF YARN THREAD to be as follows:-

Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS RELATING TO THE SIZING OF YARN
THREAD to be as follows:-
"
OR
The known methods for sizing yarns with starch prepared hot presents various
inconveniences; the baths are not uniform as regards the quantity of water, and
on their surface is formed a crust or coating which becomes attached to the yarn
during the sizing thereof; this crust or coating, when drying, frequently causes the
rupture of the yarn, or, if it should remain fixed, therein, it causes stains or spots
when the yarn is dyed.
To obviate or avoid these inconveniences I employ as a sizing bath a preparation
which is always uniform and contains the required quantity of vegetable glue or
Bize obtained cold.
I take advantage of the property possessed by alkalies of liberating the gluey
matter contained in starch, flour, or amylum, without attacking or impairing the
natural properties of the said material, and I utilize the glue or size obtained cold
in this manner for sizing yarns. This sizing can be effected, either by hand or
mechanically, upon any yarns designed for the manufacture of woven fabrics,
whether the said yarns are of wool, cotton, silk, hemp, flax or any similar
material.
I may vary the proportions of the materials which I employ in the preparation
of my vegetable size, but, by way of example, I will describe a preparation which
gives good results.
I dissolve in 60 litres of cold water from 9 to 10 kilograms of starch. Having
on the other hand dissolved 3 kilograms of caustic soda in 20 litres of cold water,
I mix these two solutions. An alkaline glue or size is thus prepared cold; this
glue or size is rendered neutral by mixing therewith 20 litres of cold water in

and employ an alkaline glue or size, I dissolve the 8 kilograms of soda in 40 litres
of water.
This glue or size in a cold state, produces the best result for sizing purposes.
By my improved process I obtain economy and security in the sizing operations.
may somewhat vary the proportions and materials employed for the preparation
of my vegetable glue or size, and I may, if desired, use potash, caustic soda, salts

This invention relates to the sizing of yarn or thread.
The known methods for sizing yarn or thread with starch prepared hot present
various inconveniences; the baths are not uniform as regards the quantity of
water, and on their surface is formed a crust or coating which becomes attached to
the yarn or thread during the sizing thereof; this crust or coating, when drying,
frequently causes the rupture of the yarn or thread or, if it should remain fixed
therein, it causes stains or spots when the yarn or thread is dyed.
To obviate or avoid these inconveniences I employ, as a sizing bath, a preparation
which is always uniform and contains the required quantity of vegetable glue or
size obtained cold.
I take advantage of the property possessed by alkalies of liberating the gluey
matter contained in starch, flour, or amylum, without attacking or impairing the
natural properties of the said material, and I utilize the glue or size obtained cold
in this manner for sizing yarns. This sizing can be effected, either by hand or
mechanically, upon any yarns designed for the manufacture of woven fabrics,
whether the said yarns are of wool, cotton, silk, hemp, flax, or any similar
material.
I may vary the proportions of the materials which I employ in the preparation
of my vegetable size, but, by way of example, I will describe a preparation which
gives good results.
I dissolve from 9 to 10 kilograms of starch in 60 litres of cold water, and I also
dissolve 3 kilograms of caustic soda in 20 litres of cold water; I then mix these
two solutions. An alkaline glue or size is thus prepared cold. This glue or size
is rendered neutral by mixing therewith 20 litres of cold water in which has been
diluted 1 kilogram of sulphuric acid. If it is desired to obtain and employ an
alkaline glue or size, I dissolve the 3 kilograms of soda in 40 litres of water.
This glue or size, in a cold state, produces the best result for sizing purposes.

of my vegetable glue or size, and I may, if desired use potash, caustic soda, salts
with a base of potash and soda, lime, magnesia, zinc and the like, and either
sulphuric, hydrochloric, acetic, nitric, or other acid.

page_text: 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 employment, for sizing yarn or thread of any kind, of a vegetable glue or
size prepared cold by causing an alkali to react upon starch; flour, or amylum &
dissolved in cold water, as described.
