Improvements in the Manufacture of Textile Fabrics for
Underclothing.
I, CARL MÜHLINGHAUS of Lennep, Germany, Owner of the Firm of
C. Mühlinghaus, Peter Johann Sohn, 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 a new method of making textile fabrics and to such
fabrics for underclothing, which is to be worn on the body. These fabrics having
the quality of keeping the body dry, that is to say of taking up the vapour and
humidity ensuing from perspiration, and conducting it away from the body so as to
enable it to evaporate outwardly.
This valuable quality of the new fabric is obtained by the combination or use of
two different sorts of yarn in making the same, namely yarn of raw or unprepared
cotton containing its natural oily or greasy matter, and prepared or finished cotton
deprived of oil or grease, or in place of such yarn woollen yarn or of wool and
cotton mixed.
The raw cotton serves for making the lower part or side of the stuff, which is
worn direct on the body and it is woven or otherwise bound knitted for instance
in large, open meshes, whereas the upper side of the stuff is made of finished
cotton or of wool and cotton mixed and in close binding or small meshes.
In other words: I produce a double stuff, the inner part in open or large meshed
binding of raw cotton, the outer part in fine or close meshed binding of prepared
cotton yarn, or of woollen yarn or wool and cotton mixed.
The inner part so produced is quite unhygroscopical, that is to say, it does not
absorb humidity at all and is therefore always dry. Being bound or woven in large
meshes it allows free exit of the humidity or vapours caused by perspiration to
the outer part, which is made of prepared cotton or of wool or of wool and
cotton mixed, and which readily absorbs the humidity, and thus the body is always
kept dry.
The fine meshes or fine binding of the outer part present a large surface and
divide the humidity and it therefore assists the evaporation outwardly.
The wearer of a garment made of this new fabric will always feel dry and is
free of chilliness and shivering.
The new fabric may be produced in a loom of known construction fitted out
with the ordinary mechanisms for making double stuffs or it may also be produced
by means of a knitting machine of known design.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A method of making a textile fabric or cloth and the fabric made according to
this method which consists in the making of a double stuff, the inner part of which
is made in open or large meshed binding by the use of unprepared or raw cotton
still containing its natural greasy or oily matter and being therefore quite
unhygroscopical, whereas the outer part is made in fine meshed binding of ordinary
prepared or finished cotton or wool or cotton and wool mixed and capable of

page_text: absorbing humidity readily. The large meshes of the inner part allowing the
ready passage of the humidity to the outer part, which presents a large evaporative
surface and quickly evaporates the humidity absorbed.
