PROVISIONAL SPECIFICATION.
An Improvement for Extracting Oil Stains from Linen and Cotton
Yarns and Cloth (Linen and Cotton).
THOMAS FERGUSON Dyer, Roughfort Mallusk, Belfast, HUGH SEMPLE
MOMEEKIN, Bleacher Roughfort, Mallusk, Belfast do hereby declare the nature
of this invention to be as follows:-
:-
The linen & cotton yarns or fabrics to be treated are immersed in a liquid
composed of pure water in which are dissolved some or all of the following
ingredients-Alkali, soda ash, ammonia soap, black soap, mineral oil & extract of
soap (Hudson's or similar) in which liquid the yarns or fabrics are allowed to
remain for two or three hours.
They are then removed from the liquid washed thoroughly in pure water &
dried.

An Improvement for Extracting Oil Stains from Linen and Cotton
Yarns and Cloth (Linen and Cotton).
We, THOMAS FERGUSON, Dyer, Roughfort, Mallusk, Belfast, and HUGH
SEMPLE MMEEKIN, Bleacher, Roughfort, Mallusk, Belfast, 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 :-
At present during the process of spinning linen and cotton yarns and weaving
linen and cotton cloth and also in the subsequent processes it frequently happens
that drops of oil, from the machinery or otherwise fall or spark on to the fibres or
fabric, and produce stains which are most difficult to eliminate. These oil stains
cannot be removed by washing with soap and in some cases even mopping with
benzine, which is the usual method adopted, has little or no permanent effect, and
bleaching the material only confirms the stains and shows them up more distinctly.
This invention has for its object to remove the oil stains by immersing the
stained yarns or fabric in a liquid which is capable of dissolving the oil in the
stains.
The liquid is composed of the following ingredients in or about the following
nanertione mis
proportione sis
10 to 15 gallons of water.
8 lbs. of soap.
4 lbs. of ammonia alkali or soda ash.
2 lbs. of ammonia extract of soap.
1 pint of oil.

page_text: The oil used may, according to the nature of the stains, be shale oil or paraffin
oil, resin oil, aniline oil, crude aniline oil, toluidine oil, phenol oil, or the chemical
equivalents of these oils, or combinations of them.
The above proportions may be altered to suit different requirements and it is to
be understood that we give them merely by way of example and as an illustration
of what we have found to give good results in practice.
The oil used should have the property of dissolving the oil stains and we have
found that paraffin, aniline, or crude aniline oils are the best agents, according to
the nature of the stains, for this purpose and we generally prefer to use them.
Aniline, phenol, or toluidine oil is specially applicable when the stains are
produced by mineral oil.
The yarn or cloth is immersed in the liquid for from 5 to 12 hours.
The treatment not only frees the yarn or cloth from oil stains but it improves
the surface and finish of the material.
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
consider novel and desire to claim is :-
Immersing cotton and linen yarns and cloth, in order to remove oil stains, in a
liquid composed of water, soap, ammonia alkali or soda ash, ammonia extract of
soap, and a solvent mineral oil or its chemical equivalent, substantially as herein-
before described.
