Method of Manufacturing Sewed or Embroidered Lace work or
Trimmings
I, JOHANN GIORG BUHI MANN, of 60A Mulhen Strasse, Berlin, Kingdom of
Prussia, German Empe, Manufacturer, do hereby declare the nature of ny
said invention, and in what manner the same is to be performed, to be particularly
described and ascertained in ind by the following statement
-
This invention relates to a method of manufacturing sewed or embroidered lacc-
work or trimmings, and consists in general in sewing or embroidering the lacc-noih
or tummings upon a ground-stuff of base which prior to being provided with said
lace-work or trimmings has been prepared in such a nanner, that it may afterwards
be removed te destroyed by a simple dry method unable to do any injury to the
lace-work or trimmings freed thereby
There may be used as ground stuffs oi bases suitable for the process
1 All stuffs consisting of cellulose, as for instance cotton-webs, paper, and the
like
These stuffs are prepared by being first treated with, and stiffened by,
alkaline starch, and are thereafter soaked with solutions of such metal-salts, that
on being decomposed deliver or yield an acid Salts of such a kind are for
instance chloride of magnesia, and of aluminum The stuffs may, however, be
soaked directly with a diluted acid, for instance with sulphuric acid, or with
phosphoric acid, it is well known, that cellulose-stuffs treated in the afort-
mentioned way, and dried afterwards, are destroyed as soon as they are heated,
and the acid deliberated only now is able to act upon the stuff
2 All woollen stuffs These are first stiffened by means of starch, and are
thereafter soaked with diluted solutions of caustic alkalis, the latter causing later
on the destruction of the stuff when heated
In order to protect the lace-work oi trimmings against the injurious influence of
the acid or other chemical body fieed by the heated stuff, the former are impreg-
nated with suitable means, for instance with solutions of paraffine in benzene, oi
of glycerine in wate There may however, be employed also other protective
means, which may be introduced into the yun already whilst dyeing the latter
The process propu proceeds as follows Ihe lace-work or trimmings, which
have been impregnated with painffine, glycerine or any other suitable protective
means, are sewed or embroidered upon the ground-stuff on base that has prio
thereto been soaked with a suitable mordant, and dried This stuff with the lace-
work or trimmings now secured to it is heated to a temperature of from 100
to 200° C, which if desired may be performed by superheated steam The
ground-stuff or base is thereby perfectly destroyed, and may be wholly removed
by brushing, beating, shaking or any other mechanical treatment The lace-
work or trimmings may be sewed or embroidered to the ground-stuff or base br
means of a suitable machine, and also the heating may be performed by any
suitable apparatus
The lace-work o trimmings are then finished, and remain, owing to the
protective impregnation, in the previous proper state
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
-
1 A method of manufacturing sewed or embroidered lace-work or trimmings,

page_text: consisting in impregnating a ground-stuff or base with a chemical means adapted
to destroy said ground-stuff or base on being heated, producing the lace-work or
tiimmings upon the said ground-stuff or base and heating the latter so as to cause
it to be destroyed by the chemical means used for the impregnation, substantially
as described
2 A method of manufacturing sewed or embroidered lace-work or trimmings,
consisting in impregnating a ground-stuff or base first with starch, and thereafter
with solutions of salts having a component adapted to destroy said ground-stuff or
base on being heated producing the lace work or trimmings upon the said ground-
stuff or base, and heating the latter so as to cause it to be destroyed by the
corioding component of said salt, substantially as described
3 A method of manufacturing sewed or embroidered lace-work or trimmings,
consisting in impregnating a ground-stuff or base first with alkaline starch, and
thereafter with a metal-salt having as component an acid adapted to destroy said
ground-stuff or base on being heated producing the lace-work or trimmings upon
the said ground-stuff or base, and heating the latter so as to cause it to be
destroyed by the acid freed by the heating, substantially as described
4 A method of manufacturing sewed or embroidered lace-work or trimmings,
consisting in impregnating ground-stuff or be fit vith alkaline starch, and
thereafter with a diluted acid adapted to destroy sud ground-stuff or base on
being heated producing the lace-work or tuminings upon the said ground-stuff o
base, and heating the latter so as to cause it to be destroyed by the heated acid,
substantially as described
5 A method of manufacturing sewed or embroidered lace-work or tummings,
consisting in impregnating a ground-stuff or base first with starch, and thereafter
with a solution of a caustic alkali adapted to destroy said ground-stuff or base on
being heated, producing the lace-work or trimmings upon the said ground-stuff or
base, and heating the latter so as to cause it to be destroyed by the caustic
component of said alkali, substantially as described
6 A method of manufacturug sewed on mbiondered lace-work or trimmings,
consisting in impregnating a ground-stuff on base with a chemical means adapted
to destrov said ground- tuff on bast on being heated producing the lace-work or
tiimmings upon the said ground-stuff or base soakingud lace work or timmings
with chemical means adapted to protect the sand lace vor o tummings against
the destructive property of I first chemical means and heating the whole so as
to use the ground-stuff or buse to be destroyed by the said fist chemical means,
substantially as described
7 A method of manufacturing sewed or embroidered lact-work or tummings,
consisting in impregnating a ground-stuff or base with a chemical means adapted
to destroy and ground-stuff or ha con xing heated producing the lnce-work or
trimmings upon the said ground-stuff or base soaking said lace-work or trimmings
with a solution of paraffine in benzene, and heating the whole so as to cause the
ground-stuff or base to be destroyed by said chemical means, substantially as
described
