I, PAUL PARSY care of Messrs. Bede & Cie. 41 Rue du Marteau, Brussels, in the
Kingdom of Belgium, Manufacturer do hereby declare the nature of this invention to
be as follows:-
The object of the present invention is not to eliminate the gumming matter in the
flax or other textile matter, which takes place in most of the chemical steeping
processes but to perform in a rapid and efficient manner an operation analogous to
that which is effected in steeping by fermentation by the action of microbes.
For this purpose I subject the filamentous matters to the action of water which
I heat either in an open vessel or in a closed receptacle under pressure; subsequently
I subject the filamentous matters so treated in a closed receptacle for a certain time to
the action of steam only either raising at the same time both the pressure and
temperature, or using a small pressure and raising the temperature by superheating.
By this process I convert the gummy-resinous matter of the textile substance into
a soft and glossy product, which facilitates the spinning and is the same as that
produced by the process, mentioned above, still in use in country districts.
The various chemical processes of steeping known heretofore, removed the greater
part of these matters at the expense of the quality of the product.

page_text: I, PAUL PARSY in care of Messrs. Bede & Cie. 41 Rue de Marteau Brussels,
Manufacturer, 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:---
The object of the present invention is not to eliminate the gummy matter in the flax
or other textile matter, which takes place in most of the chemical steeping processes,
but to perform in a rapid and efficient manner an operation giving the same results as
the steeping by fermentation usually employed.
For this purpose I allow the matters to steep for a short time (about half an hour
for certain matters) under the action of water, heated under pressure to about 105
to 150 degrees Centigrade. The water is then replaced by steam under pressure of
5 atmospheres in which the matters are retained for about one hour.
By this process I convert the gummy-resinous matter of the textile substance into a
soft and glossy product which facilitates the spinning as in the process in use in
country districts.
The various chemical processes of steeping known heretofore, removed the greater
part of these matters to the detriment of the quality of the product.
In using large apparatus for the operation of this process, I preferably employ steam
at low pressure and heated to about 150° Centigrade.
:
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is:
In the treatment of flax and other textile matters; the process of steeping the
matter in hot water for a short time and subsequently replacing the water by steam at
150 degrees Centigrade or thereabouts and leaving this stem in contact, with the
matter for about one hour.
