AN IMPROVED ANTISEPTIC TREATMENT OF WOVEN FABRICS MADE OF COTTON
Year: 1879

page_text: LETTERS PATENT to David Samuel Bles, of Manchester, in the County of
Lancaster, for the Invention of "AN IMPROVED ANTISEPTIC TREATMENT OF
WOVEN FABRICS MADE OF COTTON." A communication from abroad by
Abraham Jeremiah Polak, of Rotterdam, Holland.
Sealed the 2nd March 1880, and dated the 22nd November 1879.
" AN
PROVISIONAL SPECIFICATION left by the said David Samuel Bles at the
Office of the Commissioners of Patents on the 22nd November 1879.
DAVID SAMUEL BLES, of Manchester, in the County of Lancaster.
IMPROVED ANTISEPTIC TREATMENT FOR WOVEN FABRICS MADE
(A communication from abroad by Abraham Jeremiah Polak, of Rotterdam,
Holland.)
of
COTTON."
The principal object of this Invention is to prepare or treat woven cotton fabrics
known as mulls or butter cloths, in which butter is kept or packed for transmission
or sale, with an antiseptic in order to prevent the butter contained therein from
becoming rancid during a voyage, or if kept for a long time, but it will be evident
that cotton cloth so treated may be used with advantage for packing other articles
of food, or other organic substances liable to putrefaction or decay, for the purpose
of preserving the same and preventing or arresting for a long period such putrefaction
or decay, and for other analogous purposes.
The Invention consists in the employment of salicylic acid for the treatment of
woven cloth made of cotton for such or similar purposes, which preparation entirely
prevents the liability of butter to turn rancid, and also the putrefaction or decay of
other organic substances which may be enveloped therein, without imparting any
flavor or odour thereto.
The solution of salicylic acid may be applied to the cloth either during the
bleaching process or by subsequent immersion therein. The strength of the solution
employed will depend in a great measure upon the purpose which it is intended to
serve, and the length of time during which it is required to preserve its antiseptic
properties, a much stronger solution being required for a long voyage than will
be sufficient to keep the butter or other article from deterioration for a short time
only.

"AN
IMPROVED ANTI-SEPTIC TREATMENT OF WOVEN FABRICS MADE OF COTTON."
(A communication from abroad by Abraham Jeremiah Polok, of Rotterdam,
Holland.)
The principal object of this Invention is to prepare or treat woven cotton fabrics
known as mulls or butter cloths, in which butter is kept or packed for transmission
or sale, with an antiseptic in order to prevent the butter contained therein from
becoming rancid during a voyage, or if kept for a long time, but it will be evident
that cotton or other cloth so treated may be used with advantage for packing other
articles of food, or other organic substances liable to putrefaction or decay, for the
purpose of preserving the same and preventing or arresting for a long period such
putrefaction or decay, and for other analogous purposes.
The Invention consists in the employment of salicylic acid for the treatment of
woven cloth made of cotton linen or other suitable fibrous material for such or
similar purposes, which preparation prevents the liability of butter to turn mouldy
and rancid, and also the putrefaction or decay of other organic substances which
may be enveloped therein, without imparting any flavor or odour thereto.
The solution of salicylic acid may be applied to the cloth, either during the
bleaching process or by subsequent immersion therein, or it might be applied to
the cloth in the grey state. The strength of the solution employed will depend in
a great measure upon the purpose which it is intended to serve, and the length of
time during which it is required to preserve its antiseptic properties, a much
stronger solution being required for a long voyage than will be sufficient to keep
the butter or other article from deterioration for a short time only.
For example, in treating grey cotton cloth, it is first bleached in the ordinary
manner by liming, steeping, souring, boiling and washing, or it may be bleached by
any other known process, and then before drying it is passed through a solution
composed of about three pounds of salicylic acid to about seventeen gallons of
water, after which it is dried by passing over tin cylinders, heated by steam.
The above is the strength of solution which I have found suitable for ordinary
purposes, and the quantity named will suffice for the preparation of about two
hundred pieces; but as before stated the quantity of salicylic acid must be
proportioned to the use to which the cloth is to be applied.
Having now described the nature and object of the said Invention, I wish it to
be understood that I claim as the Invention communicated to me from the said
Abraham Jeremiah Polok, the use of salicylic acid, substantially in the manner and
for the purposes above more particularly set forth.
In witness whereof, I, the said David Samuel Bles, have hereunto set my
hand and seal, this Seventeenth day of May, in the year of our Lord One
thousand eight hundred and eighty.
DAVID S. BLES.
