PROVISIONAL SPECIFICATION.
An Improved Method of Treating Vegetable Fibres so that they will
Spin More Easily and Make Stronger Yarn, Thread, or Strand.
KENNETH THOMAS SUTHERLAND 39 Pritchard Street, Chorlton upon Medlock
Manchester Chemical Manufacturer and GEORGE ESDAILE The Old Rectory Platt in
Rusholme Manchester Civil Engineer do hereby declare the nature of this invention
to be as follows:-
We put our invention into effect in the following manner-
With such fibres as cotton, that are not usually put through any chemical process
before spinning; we place them in a not severe hot, or cold alkaline solution-by
preference carbonate of soda-in which we work them for about three hours, then wash
in water, dry, and prepare for spinning.
For such fibres that have been freed from gummy or mucilagenous matter-except-
ing such as have been treated by our process No. 15333, 30 Sept. 1889, styled,
Improvements in the treatment of fibres and fibrous material made of China-grass,
flax, hemp, and the like fibres, by which means such can be more easily cleansed and
bleached -we either work them for about three hours in a hot, or cold bath-cold by
preference or boil for about three hours in a not severe alkaline solution-by
preference, carbonate of soda ;-wring out, and pass into water, dry and prepare for
spinning.

An Improved Method of Treating Vegetable Fibres so that they will
Spin More Easily and Make Stronger Yarn, Thread, or Strand.
KENNETH THOMAS SUTHERLAND Chemical Manufacturer, 39 Pritchard Street,
Chorlton-upon-Medlock Manchester and GEORGE ESDAILE Civil Engineer The Old
Rectory, Platt in Rusholme, Manchester 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 :-
We put our invention into effect in the following manner, with such fibres as cotton
that are not usually put through any chemical process before spinning, we place them
in a vat or bath containing a not severe hot or cold, the latter preferred, alkaline
solution, by preference carbonate of soda, standing at about 2 to 4T in which we work
them for say about three hours, then wash in water, dry and prepare for spinning.
For such fibres that have been freed from gummy or mucilageneous matter, except by
our process No. 15333, 30 Sept. 1889 styled "Improvements in the treatment of fibres
and fibrous materials, made of China-grass, flax, hemp, and such like fibre, by which
means such can be more easily cleansed and bleached;" we either work them for
about three hours in a hot or cold bath, cold by preference, or boil for about the
same time, in a not severe alkaline solution, by preference carbonate of soda, standing
at about 2 to 4, wring out, pass into water, dry, and prepare for spinning.
"
After the fibres have been worked in the beforementioned solution they will be found
to "flock;" and to have the advantage of spinning on cotton machinery when
artificially shortened to the required length; and further that the fibre will spin more
easily and make stronger, yarn, thread or strand,

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be prepared, we declare that what we
claim is―
1. That vegetable fibres treated by this process will "flock."
2. That fibres when prepared by this process and artificially shortened to the length 5
of cotton will spin on cotton machinery.
3. That fibres when manipulated by this process, will spin more easily and make
stronger yarn thread or strand.
