page_text: MANUFACTURE OF SIZE, AND IN THE APPLICATION OF A CERTAIN MATERIAL FOR CON-
DITIONING COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
:-
Our Invention consists in the application of sulphate of zinc and
tungstate of soda to farinaceous or other size, to increase its stiffening
and feeding properties and to prevent mildew in the yarn or fabric
prepared with the improved size.
In preparing our improved size we dissolve spelter in sulphuric acid to
obtain the sulphate of zinc, which we mix and boil with the farinaceous
or other size in any required proportion.
"
Our improvement in the application of a certain material for con-
ditioning cotton and other fibrous substances consists in applying a
solution of tungstate of soda to the cotton or other fibrous substances
when in an unmanufactured or manufactured state.
