PROVISIONAL SPECIFICATION.
Improvements in or connected with Electrolytic Bleaching of Baled
Yarns.
I, ALFRED AUGUST VOGELSANG, of No. 541, Rosenstrasse, Dresden, in the
Kingdom of Saxony, Engineer, do hereby declare the nature of this invention to
be as follows:
-
This invention relates to improvements in, or connected with, the electrolytic
bleaching of baled yarns and is as follows:
In order to bleach large quantities of cotton yarns, cheaply and effectively, it
is essential that such yarns be packed in the receptacle before being treated with
the bleaching fluids, in a certain manner.
By my invention, as hereinafter described, large quantities at a time of bundled
or baled yarns can be bleached to a perfect degree of whiteness without having
to be unpacked.
To obtain the desired result, I place the yarns, either in single pounds or in
packets of several pounds in the receptacle in such a manner that the bleaching
Huids employed operate upon the threads lengthwise, or in other words, in the
direction of the fibres. This I effect, by placing the bundles or bales of yarns
in the receptacle (which is open at the top) in a perpendicular position instead
of being laid flat as hereinbefore was the case.
The advantages obtained by arranging the yarns in the foregoing manner, are
most noticeable when bundles or bales of several pounds are treated, as it
simplifies the process and causes a great saving of time in addition to ensuring
the proper bleaching of the threads.

COMPLETE SPECIFICATION.
Improvements in or connected with Electrolytic Bleaching of Baled
Yarns.
I, ALFRED AUGUST VOGELSANG, of No. 541, Rosenstrasse, Dresden, in the
Kingdom of Saxony, Engineer, 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;
This invention relates to improvements in, or connected with, the bleaching
of baled yarns, and is as follows:
According to the bleaching process hitherto employed the yarn had to be

page_text: placed flat or obliquely in a bleaching vat in the form of single pound bundles
and so subjected to an entire process of bleaching. The packing of single pound
bundles laid flat or obliquely involved however the undoing of the bundles o
bales of yarn (as they are made up and delivered by the spinning mills) and the
re-arranging them into pound bundles after the yarn had been tied up, that is
to say, after the several hanks or skeins of yarn in a pound bundle had been
held apart by means of strong binding threads, in order that there would be no
entangling of the threads by the handling of the yarn in bundles, which consti-
tuted a cause of waste of yarn.
The packages of yarn in bundles or bales delivered from the spinning mills
heretofore had to be taken apart for the purpose of tying up the different hanks
of yarn as aforesaid.
With the novel and original packing process hereinafter described, the undoing
of the packages or bales of yarn and the tying up the different hanks of yarn is
avoided, the packages or bales of yarn being placed in the bleaching vat, as they
come direct from the spinning mill, in such a manner that the circulating fluid
moves in the direction of each single thread of the yarn.
These packages of yarn in bundles or bales can be treated in quantities up to
5,000 pounds in weight at once in one bleaching vat, that is to say, bleached
white without spot or stain.
My packing process is intended to effect economical bleaching, which is en-
sured by dispensing with the undoing of the packages or bales of yarn and the
tying up of the different hanks of yarn; and the bleaching of large quantities of
yarn in bundles or bales at once to perfect whiteness.
The accompanying drawing illustrates the arrangement of the packing.
A represents the bleaching vat, in which the packs of yarn B, consisting of
yarn in bundles or bales of 5 to 10 pounds weight, are placed in several layers,
one above the other, in a vertical position, whereby the circulating fluid moves in
the direction of the yarn threads, thus rendering possible a perfectly spotless
bleaching.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner. the same is to be performed, I declare that what
I claim is:-
The process for the bleaching of cotton yarn in bundles or bales, the dis-
tinguishing feature of which is that yarn in bundles or bales of several pounds
weight as delivered from the mills and without having to be unpacked or the
hanks held apart and tied up into small bundles, is packed vertically in a bleach-
ing vat, the said bundles or bales being placed adjoining and one above the other,
so that the circulating fluid moves in the direction of the yarn threads, for the
purpose of ensuring the economical and spotless bleaching of large quantities
of material treated at one time, substantially as described and illustrated.
Dated this 23rd day of April 1900.
