KENNETH THOMAS SUTHERLAND Chemical Manufacturer 39 Pritchard Street Chorlton'
on Medlock, Manchester & GEORGE ESDAILE Civil Engineer The Old Rectory, Platt
in Rusholme Manchester do hereby declare the nature of this invention to be as
follows:
For improvements in the treatment of Fibres & Fibrous Materials made of China-
grass, Flax, Hemp, & the liko fibres by which means such can be more easily cleansed
and bleached.
•
We carry our process into effect in the following manner: We take the fibre or
material which has to be treated & place it in an alkaline solution--not severe-in
which we mix mineral oil or wax, by preference the former, we work this fibre
or material in it from balf an hour to three hours-but this must be in accordance
with the condition of the fibre or material under treatment; when removed from the
bath or solution, we wring out the fibre or material & wash in water, but the fibre
or material may be dried without washing; when dry we steep in paraffin oil in
which we leave it to penetrate the fibre; we then squeeze or wring out & pass it
into an alkaline solution-not severe, afterwards squeeze or wring out & pass into a
vat or vessel containing water, cold by preference in which we steep, beat, squeeze
or hammer until the fibre or material becomes bleached, if after this, the result is not
obtained, the process is repeated from the steeping in paraffin oil until the fibre is
thoroughly cleansed & bleached.

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 invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-—
Our invention consists in the treatment of Fibres, and Fibrous Materials made of
China-grass, Flax, Hemp, and such like fibres by which means such can be more
easily cleansed and bleached.
We carry our process into effect in the following manner; we take the fibre or
material which has to be treated and place it in an alkaline solution, by preference
carbonate of soda not severe, to stand at about 2 to 4 in which we mix mineral
oil or wax by preference the former about one pint of oil, or lb. of wax, to eight
gallons of solution we work the fibre or material in this solution, which we use
hot or boiling, from one half hour to three hours, but the time depends on the state
of the fibre or material under treatment, when removed from the bath or solution we
wring out the fibre or material and wash in water, then dry. When dry we steep
in paraffin oil, in which we leave it to penetrate the fibre, we then squeeze or wring

stand at say about 2 to 4.
The fibre or material to be worked in this solution from ten minutes to half an
hour.
This solution may be used either hot or cold, but we give preference to the latter
or only having it luke warm; afterwards squeeze or wring out and pass into a vat
or vessel containing water, hot or cold, in which we steep, beat, squeeze or hammer,
until the fibre or material becomes cleansed and bleached. If after this the result
obtained is not satisfactory, the process is repeated once or more from the steeping
in paraffin oil, until the fibre or material is bleached and thoroughly cleansed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
1. Fibres and fibrous materials prepared by this process are more easily cleansed
and bleached, without any fear of injuring the fibre.
2. The fibre when so prepared may be spun in short or longer lengths as
required.
3. The fibre will "flock."
4. By spinning the fibre in short lengths the waste is less.
5. Fibrous materials prepared by this process are not so liable to
