Improvements in Woven Stuffs with Silk Imitations.
I, HEINRICH EDELHOFF, of Gartenstrasse No. 15, Barmen, Rhenish Prussia,
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:-
This invention relates to a new woven stuff especially intended as lining cloth
for great coats and the like, for which purposes half silk cloth or cheap silks have
been used hitherto. In the first case silk designs were woven into the cotton
ground in biassed tweel or in satin tweel binding or such suitable bindings
bringing the silk design into effect; the silk lining stuffs are mostly woven
uniformly in ordinary tweel, with or without designs, but as said before, in both
cases the price of these lining stuff's does not allow to use good silk and in the
half silk stuffs therefore the silk designs are soon worn.
Now by my invention a good strong lining stuff is produced which answers all
the requirements requested; it has the same appearance like half silks, but is
more durable and much cheaper than these and also better than the ordinary
cheap lining silks of minor quality.
My new lining stuff consists of best cotton weaving in suitable binding, by
preference satin tweel, into this are laid suitable designs in any convenient pattern
consisting in plain stripes or more figurative ornaments.
In order to produce these figurative, silk like effects I use cotton yarn which
was dyed in strong alkaline lyes or strong acids by which process these yarns
get a bright and shining appearance like silk, without losing in strength and a
piece of cloth thus produced then exactly resembles the half silks mentioned
above, but is much stronger and more durable in wear than those. The silk like
patterns or figurative designs may be produced by warp or by weft threads of
rotton yarn of the prescribed character; this is a matter for the weaver to decide.
The gist and essential of my invention consists in this that silk like effects are
produced in woven (lining) stuffs without the use of silk yarn by laying in a
ground of cotton weaving, designs and figurative effects of any form, produced
by the use of cotton yarn dyed in strong alkaline lyes or in strong acids-(so
called helios silk or mercerised" cotton yarns)- as warp or weft threads in the
respective parts of the stuff.
"
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 of producing silk like effects in woven goods (and the goods so
produced) by using either as warp threads or as weft threads in those parts of a
piece of weaving, where such effects are to be produced, cotton yarn dyed in
strong alkaline lyes or in strong acids-(so called helios silk or mercerised cotton

page_text: yarn) and by using such manners of binding, that these yarns produce patterns
or figurative designs, which lie open or raised in the ground of the stuff made of
ordinary cotton yarn.
