An Improved Process for Lustreing Mercerised Yarn.
I, CARL ALBERT ADOLF FISCHER, of Reutlingen, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved process for lustreing mercerised yarn
and has for its principal object to obtain a better lustre or gloss without destroy-
ing the elasticity of the yarn or the superior condition for dyeing into which
the yarn is brought by the mercerising process.
The process of lustreing mercerised yarn by holding it under tension to
counteract shrinkage and the further process of increasing the length of the
yarn beyond its original length by stretching it whilst still wet with the mercer-
ising liquid are both well known.
My invention consists in steaming the yarn, preferably in a closed vessel or
chamber, after the yarn has been mercerised under tension or after it has been
subjected to subsequent stretching by either of the lustreing processes above
indicated or any equivalent process.
I find that yarn thus treated has a much brighter lustre, a more glossy appear-
ance and a more silky "feel" without losing its elasticity or its affinity for
certain dyes.

COMPLETE SPECIFICATION.
An Improved Process for Lustreing Mercerised Yarn.
I, CARL ALBERT ADOLF FISCHER, of Reutlingen, in the Empire of Germany,
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 :-
My invention relates to an improved process for lustreing mercerised yarn
and has for its principal object to obtain a better lustre or gloss without destroy-
ing the elasticity of the yarn or the superior condition for dyeing into which
the yarn is brought by the mercerising process.
The process of lustreing mercerised yarn by holding it under tension to
counteract shrinkage and the further process of increasing the length of the
yarn beyond its original length by stretching it whilst still wet with the mercer-
ising liquid are both well known.
My invention consists in steaming the yarn (when dried) with steam under

page_text: pressure in a closed vessel or chamber, after the yarn has been mercerised under
tension or after it has been subjected to subsequent stretching by either of the
lustreing processes above indicated or any equivalent process.
I find it advantageous to support the yarn on wooden rods suitably arranged
within the chamber and to subject the yarn to a steam pressure of say one and
a half atmospheres the time during which the steaming is continued being
approximately forty minutes.
k
I find that yarn thus treated has a much brighter lustre, a more glossy appear-
ance and a more silky" feel without losing its elasticity or its affinity for
certain dyes.
:
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is―
The improved process of treating yarn mercerised by any of the known
Justreing processes said improved process consisting in steaming the said yarn
(when dried) with steam under pressure in a closed vessel or chamber substan-
tially as herein set forth.
