PROVISIONAL SPECIFICATION.
Sizing Compounds for Cotton Yarn.
I SORABJEE CURSETJEE DHONDY of Byculla Bombay, India, Weaving Master
do hereby declare the nature of this invention to be as follows:-
My said invention relates to the employment in combination with the ordinary
materials used in sizing cotton yarns of certain additional substances which serve
to whiten and strengthen the threads and to impart a superior feel and finish to the
cloth woven therefrom as well as to assist in retaining the size on the threads during
the
process of weaving.
One of the principal ingredients hereinafter referred to is derived from the fruit
of the "Augustus palm which grows
in India and is known in the Gujrati
language as Areetha." When this fruit is rubbed or soaked in water it imparts
detergent properties thereto. I prefer to use an aqueous extract of the said fruit in
combination with chloride of magnesium (antiseptic), bleaching powder, caustic
soda and gloy. Each of these ingredients is separately dissolved in water and the
whole of them are then mixed together and filtered. The compound solution thus
produced I term "Palm water for sizing" which is used mixed in varying pro-
portions with the ordinary sizing materials. In some cases I may use caustic soda
and bleaching powder alone or in combination along with the ordinary materials used
for sizing cotton yarn and I may also employ an aqueous extract of the "Augustus
palm" uncombined with the other ingredients hereinbefore referred to as an addition
to ordinary sizing materials.
Dated this Twenty-ninth day of April 1891.

Sizing Compounds for Cotton Yarn.
I SORABJEE CURSETJEE DHONDY of Byculla Bombay, India, Weaving Master
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 :-
My said invention relates to the employment in combination with the ordinary
materials used in the composition of size for cotton yarns of certain additional sub-
stances which serve to whiten and strengthen the threads and to impart a superior
feel and finish to the cloth woven therefrom as well as to assist in retaining the size
on the threads during the process of weaving.
One of the principal ingredients hereinafter referred to is derived from the fruit
of the "Augustus palm which grows in India and is known in the Gujrati
language as Areetha." When this fruit is rubbed or soaked in water it imparts
detergent properties thereto. I preferably make use of an aqueous extract of the
said fruit in combination with chloride of magnesium (antiseptic), bleaching powder,
caustic soda, and "gloy" dissolved in water. The solution when ready for addition
to the size I term "Palm water for sizing."

The following are the directions for preparing one gallon say nine pounds of the
said compound solution :
1. Take 16 ounces of "Augustus palm” fruit and triturate with cold water until
the water has taken up as much of the soluble matter of the fruit as possible. As
much water is used as is necessary to obtain a solution indicating 5° Twaddell.

page_text: 2. Take 24 ounces of chloride of magnesium (antiseptic) steam it well and when
cooled to 120° Fahrenheit dilute with water until its specific gravity is equal to
25° on Twaddell's hydrometer.
3. Take 4 ounces of bleaching powder and dissolve in sufficient water to indicate
5° Twaddell.
4. Take 4 ounces of caustic soda and dissolve in as little water as possible: then
dilute this solution with four or five times its bulk of water.
5. Take 16 ounces of "gloy" and when well steamed dilute with water until it
indicates 10° Twaddell.
All the foregoing five solutions are then placed in a vat and sufficient water is
then added to bring the total weight to nine pounds. After a thorough mixing the
whole is filtered and is then ready for use as an addition to the ordinary size used
for cotton warps.
The quantity to be added may be varied according to the effect to be produced
but for ordinary qualities of cotton warp I prefer to add one gallon of "Palm water
for sizing to every 30 gallons of the ordinary size.
"
Although I have hereinbefore given the proportions of the ingredients and have
described a specific method of preparing such ingredients it is to be understood that
such proportions and such methods are only given by way of illustration and as
indicating the proportions and methods of preparation I prefer to adopt and they
may be varied according to circumstances. Some or all of the ingredients herein-
before mentioned in the passages numbered 2, 3, 4 or 5 may be omitted and an
extract of the "Augustus palm" may alone be used as an addition to the ordinary
sizing ingredients.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is:
1. The use in combination with the usual sizing ingredients of the solution "Palm
water for sizing" composed and prepared substantially as hereinbefore set forth for
the purpose of sizing cotton yarns.
2. As an addition to the ordinary sizing solution used for cotton yarns the use of
an extract of the "Augustus palm " fruit either alone or combined with other
substances substantially as and for the purpose hereinbefore set forth.
Dated this Twenty-sixth day of June 1891.
