Year: 1883

page_text: LETTERS PATENT to Thomas Holliday of the firm of Read Holliday and Sons
of Huddersfield, in the County of York, Manufacturing Chemist for an
Invention of IMPROVEMENTS IN DYEING SILK OR OTHER TEXTILE FIBRES.
Communicated to him from abroad by Eugene Rau of South Manchester in
the State of Connecticut in the United States of America, Dyer
PROVISIONAL SPECIFICATION left by the said Thomas Holliday at the
Office of the Commissioners of Patents on the 29th May 1883.
THOMAS HOLLIDAY of the firm of Read Holliday and Sons of Huddersfield in
the County of York, Manufacturing Chemist. "IMPROVEMENTS IN DYEING SILK
OR OTHER TEXTILE FIBRES." (communicated to me from abroad by Eugene Rau
of South Manchester, in the State of Connecticut in the United States of America,
Dyer)
The invention relates to the dyeing of Silk or other textile fibres raw or in state
of manufacture and together or separate, but it is especially applicable to dyeing
plushes, velvets, faille silks, ribbons, laces, and fabrics in which the lustre of the
silk requires to be preserved.
In carrying out the invention I select in the first place a colouring matter which
is soluble or which has been so prepared as to be soluble in Oil or in fatty Acid or
in a mixture of Oil and Fatty Acid and I then dissolve this colour in a bath of Oil
preferably Olive Oil to which may be added a fatty acid according to the solubility
of the colour and it is proposed further to dilute it in some cases where a thin and
very fluid bath is an advantage to assist penetration and spreading of the colour
with a spirit such as bisulphide of Carbon or benzine hydrocarbons or similar
spirit distilled from Coal-Coal Tar-Petroleum-Shale et cetera
The fibre or fabric to be dyed may be boiled in the usual manner to prepare it
for dyeing in some previous stage of manufacture and be dry when impregnated
with a bath made as above described consisting of a solution of such suitable
ID 177

page_text: colouring matter in oil or oil and fatty acid preferably that known as Oleic Acid
which bath may be further reduced if desired by benzine or its equivalent as
above set forth and the surplus colour removed from it by pressure or other
mechanical or other means, and allowing the surplus colour to return to the bath.
The material is then steamed, the light spirit being previously removed by
evaporation and the superfluous oil then removed by washing with a spirit
insoluble in water that will evaporate easily without leaving a smell and will
dissolve the oil without affecting the colour, such as Bisulphide of carbon and
rectified Benzine Hydrocarbons. The spirit is removed by evaporation and the
material again submitted to the action of steam.
Should the colouring not be dark enough the first operations of impregnation,
evaporation and steaming can be repeated before removing the oil by washing and
also the whole operation can be repeated for a similar effect.

The invention relates to the dyeing of Silk or other textile fibres raw or in state
of manufacture and together or separate but it is especially applicable to dyeing
plushes, velvets, faille silks, ribbons, laces, and fabrics in which the lustre of the
silk requires to be preserved.
In carrying out the invention I select in the first place a coloring matter which
is soluble or which has been so prepared as to be soluble in oil or in fatty acid or
in a mixture of oil and fatty acid and I then dissolve this color in a bath of oil
preferably Olive oil to which may be added a fatty acid according to the solubility
of the color and it is proposed further to dilute it in some cases where a thin and
very fluid bath is an advantage to assist penetration and spreading of the color
with a spirit such as bisulphide of Carbon or benzine hydro-carbons or similar
spirit distilled from Coal-coal tar-petroleum-shale et cetera.
The fibre or fabric to be dyed may be boiled in the usual manner to prepare it
for dyeing, in some previous stage of manufacture, and be dry when impregnated
with a bath made as above described consisting of a solution of such suitable
Coloring matter in oil or oil and fatty acid preferably that known as Oleic acid
which bath may be further reduced if desired by benzine or its equivalent as
above set forth and the surplus color removed from it by pressure or other
mechanical or other means and allowing the surplus color to return to the bath.
The material is then steamed the light spirit being previously removed by
evaporation and the superfluous oil then removed by washing with a spirit
insoluble in water that will evaporate easily without leaving a smell and will
dissolve the oil without affecting the color such as Bisulphide of carbon and
rectified benzine hydro-carbons. The spirit is removed by evaporation and the
material again submitted to the action of steam.
Should the coloring not be dark enough the first operations of impregnation
evaporation and steaming can be repeated before removing the oil by washing and
also the whole operation can be repeated for a similar effect.
Having thus described the nature of the said invention as communicated to me
I would have it understood that what I claim is the Improvements in dyeing silk
or other textile fibres substantially as herein described.
In witness whereof I the said Thomas Holliday have hereunto set my hand and
seal this Twelfth day of November in the year of our Lord One thousand eight
hundred and eighty three.
