PROVISIONAL SPECIFICATION.
Improvements in Treating or Cleansing Paper-making Materials and
other Fibrous Materials and Fabrics.
We, ROBERT HAMILTON, of 29 St. James Square, Edinburgh, in the County of
Mid Lothian, North Britain, Iron and Steel Merchant, and JAMES CULLEN HAMILTON,
of Linlithgow Oil Works, in the County of Linlithgow, North Britain, Oil Works
Manager, do hereby declare the nature of this Invention to be as follows, that is
to say:
Our said Invention has for its object to improve processes employed in treating
paper-making materials and other fibrous materials and fabrics.
In carrying out our Invention we employ in the processes referred to certain
sulphonic acids or sodium or potassium salts thereof, such sulphonic acids being
obtained by treating bodies known as olefines with sulphuric acid." Such substances,
suitable for our purpose, are economically obtained as bye products of the processes
employed in refining mineral oils; but may also be derived from other sources in well
known ways.
We use the said acids or salts alone or in combination with mineral or fatty oils for
the treatment of rags, wood, esparto, straw, and other paper-making materials. We
prefer to apply the substance in a neutral form and to add it to the materials to be
operated on whilst they are being treated with caustic soda in the ordinary way, the
proportion added being regulated to suit the amount of cleansing action required in
each case.
In the case of textile materials and fabrics the substance hereinbefore specified is to
be used in the operations for washing, soaping, scouring, or bleaching such materials
and fabrics.

COMPLETE SPECIFICATION.
Improvements in Treating or Cleansing Paper-making Materials and
other Fibrous Materials and Fabrics.
We, ROBERT HAMILTON, of 29 St. James Square, Edinburgh, in the County of
Mid Lothian, North Britain, Iron and Steel Merchant, and JAMES CULLEN HAMILTON,
of Linlithgow Oil Works, in the County of Linlithgow, North Britain, Oil Works
Manager, 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, that is to say :-
Our said Invention has for its object to improve processes employed in treating
paper-making materials and other fibrous materials and fabrics.
In carrying out our Invention we employ in the processes referred to certain
sulphonic acids or sodium or potassium salts thereof, such sulphonic acids being
obtained by treating bodies known as olefines with sulphuric acid. Such substances
suitable for our purpose, and to which we apply the term "tergolene" are
economically obtained as bye products of the processes employed in refining mineral
oils; but, may also be derived from other sources in well known ways.
We use the said acids or salts alone or in combination with mineral or fatty oils for
the treatment of rags, wood, esparto, straw, and other paper-making materials. We
prefer to apply the substance in a neutral form and to add it to the materials to be
operated on whilst they are being treated with caustic soda in the ordinary way, the
[Price 4d1

in each case.
In applying our Invention to paper-making materials we proceed, after the
esparto or other material has been subjected to the usual picking process, to boil
it in the usual way with caustic soda; and in order to further bleach and whiten
the material as well as to reduce the quantity of caustic soda we add about 5 per
cent. of tergolene along with the caustic soda and boil under pressure in the well
known manner.
After the material has been boiled, it is washed, bleached, sized,
and finished in the ordinary way.
In the case of textile materials and fabrics the substance herein before specified
is to be used in the operations for washing, soaping, scouring, or bleaching such
materials and fabrics.
For scouring wool, for example, a solution of tergolene may be used alone or
along with alkalies such as caustic soda, carbonate of soda, carbonate of ammonia,
or solution of caustic ammonia. Thus the wool may be placed in a solution of
caustic alkali of a specific gravity of from 1.075 to 1.250, and to every 100
gallons of this solution 5 gallons of tergolene may be added. The solution is
heated to from 120 to 135 degrees Fahrenheit or higher according to require-
ments, and the wool is moved about in the solution or the solution is made to
circulate during. 20 to 30 minutes; and thereafter the wool is washed in warm or
cold water.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we
claim is
The use of the substances hereinbefore termed " 'tergolene " for treating or
cleansing paper-making materials, and other fibrous materials and fabrics, substan-
tially in the manner hereinbefore described.
Dated this Twenty-second day of October 1889.
