IMPROVED PROCESSES FOR TREATING COTTON, SILK, WOOL, FLAX, HEMP, AND CHINA GRASS IN A MANUFACTURED OR UN-MANUFACTURED STATE, TO PREPARE THEM FOR BLEACHING, DYEING, AND PRINTING.”
Year: 1878

page_text: LETTERS PATENT to William Mather, of the Firm of Messieurs Mather and
Platt, of Salford, in the County of Lancaster, Engineer, and Joseph Julius
Sachs, of Preston, in the same County, Manufacturer, for the Invention of
"IMPROVED PROCESSES FOR TREATING COTTON, SILK, WOOL, FLAX, HEMP,
AND CHINA GRASS IN A MANUFACTURED OR UN-MANUFACTURED STATE, TO
PREPARE THEM FOR BLEACHING, DYEING, AND PRINTING.”
PROVISIONAL SPECIFICATION left by the said William Mather and Joseph
Julius Sachs at the Office of the Commissioners of Patents on the 28th
December 1878.
WILLIAM MATHER, of the Firm of Messieurs Mather and Platt, of Salford, in
the County of Lancaster, Engineer, and JOSEPH JULIUS SACHS, of Preston, in
the same County, Manufacturer. "IMPROVED PROCESSES FOR TREATING COTTON,
SILK, WOOL, FLAX, HEMP, AND CHINA GRASS IN A MANUFACTURED OR
UN-MANUFACTURED STATE, TO PREPARE THEM FOR BLEACHING, DYEING, AND
PRINTING."
Our Invention consists in subjecting cotton, silk, wool, flax, hemp, and China
grass in the un-manufactured state, or when spun into yarn or woven into fabrics,
to the action of a stamping or beetling machine, whereby the fibres are brought into
the best condition for undergoing the processes of bleaching, dyeing, and printing,
and whereby the various processes for fixing and developing colours may be either
entirely dispensed with or greatly facilitated.
When yarns or fabrics are to be dyed or printed of a dark colour the process of
bleaching may be entirely dispensed with, and the grey yarn or fabric after having
been beetled is taken direct to the dye vat. The process of beetling opens or pre-
pares the fibres to absorb the dye materials, and a brighter and darker colour is
obtained with the same amount of dye material and in much less time than was
heretofore possible. The washing processes now necessary are also reduced.

page_text: In dyeing light colours and delicate shades, or whenever it may be desirable to
bleach the yarn or fabric either before dyeing or printing or otherwise, we beetle
the grey yarn or fabric and then bleach it in the usual manner; the beetling process
brings the fibres into the desired condition for being bleached in less time and with
less bleaching material than usual, or the fabrics may be beetled both before and
after bleaching.
When the yarn or fabric has been bleached it may be passed through a mordant
composed of any suitable materials according to the colours desired, and then dyed
in the usual manner.
In all cases the effect of the beetling before dyeing or printing is to impart a
peculiar soft and lustrous appearance to the fabrics when dyed or printed.
When operating upon un-manufactured fibres they are placed by preference
between two sheets of fabric and then beetled on a flat surface or on a roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Mather and Joseph Julius Sachs in the Great Seal
Patent Office on the 28th June 1879.
WILLIAM MATHER, of the Firm of Messieurs Mather and Platt, of Salford, in
the County of Lancaster, Engineer, and JOSEPH JULIUS SACHS, of Preston, in
the same County, Manufacturer. "IMPROVED PROCESSES FOR TREATING COTTON,
SILK, WOOL, FLAX, HEMP, AND CHINA GRASS IN A MANUFACTURED OR
UN-MANUFACTURED STATE, TO PREPARE THEM FOR BLEACHING, DYEING, AND
PRINTING."
Our Invention consists in subjecting cotton, silk, wool, flax, hemp, and China
grass, jute, and other fibres in the un-manufactured state, or when spun into yarn or
woven into fabrics, to, the action of a stamping or beetling machine, whereby the
fibres are brought into the best condition for undergoing the processes of bleaching,
dyeing, and printing, and whereby the various processes for fixing and developing
colours may be either entirely dispensed with or greatly facilitated.
When yarns or fabrics are to be dyed or printed of a dark colour the process of
bleaching may be entirely dispensed with, and the grey, or bleached, or prepared
yarn or fabric after having been beetled is taken direct to the dye vat; the process
of beetling opens or prepares the fibres to absorb the dye materials, and a brighter
and darker colour is obtained with the same amount of dye material and in much
less time than was heretofore possible. The washing processes now necessary are
also reduced, and when advisable we beetle the yarn or fabric when soaked with
the dyeing or preparing liquid in the wet stage and thus obtain a better and more
durable colour.
In dyeing light colours and delicate shades, or whenever it may be desirable to
bleach the yarn or fabric, either before dyeing or printing or otherwise, we beetle
the gray yarn or fabric and then bleach it in the usual manner; the beetling process
brings the fibres into the desired condition for being bleached in less time and with

page_text: less bleaching material than usual, or the fabrics may be beetled both before and
after bleaching.
When the yarn or fabric has been bleached it may be passed through a mordant
composed of any suitable materials according to the colours desired and then dyed
in the usual manner.
In all cases the effect of the beetling before dyeing or printing is to impart a
peculiar soft and lustrous appearance to the fabrics when dyed or printed.
When operating upon un-manufactured fibres they are placed by preference
between two sheets of fabric and then beetled on a flat surface or on a roller.
Having thus stated the nature and particulars of our Invention, we declare that
we claim,―
First. Subjecting cotton and other fibrous substances or materials to the action of
a stamping or beetling machine before they are submitted to the processes of
bleaching, dyeing, and printing, for the purposes described; and,
Secondly. Subjecting cotton and other fibrous substances or materials to the
action of a stamping or beetling machine both before and during the processes of
bleaching, dyeing, and preparing, for the purposes described.
In witness whereof, I, the said Joseph Julius Sachs, for myself and on behalf
of the within named William Mather, have hereunto set my hand and seal,
this Twenty fourth day of June, One thousand eight hundred and seventy
nine.
JOSEPH JULIUS SACHS. (L.S.)
