Improvements in and relating to Lint.
I, JAMES WOOD JOHNSON, a citizen of the United States of America, doing
business at No. 92 William Street, in the City, County and State of New York,
one of the United States of America, Manufacturing Chemist, 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 :-
The object of my improvement is to provide absorbent lint in compact form and
flexible packages, to adapt it to be conveniently used by dentists as an absorbent,
or as lint in dressing wounds, and for many other purposes, and which, although
highly absorbent, will leave no fibres adhering to the parts to which it is applied.
I attain these objects with the lint or dressing to which I have given the name of
"Lintine," shown in the accompanying drawings, in which--
$6
Figure 1 represents a portion of a lint package or a sheet thereof, obtained in
accordance with my invention.
Figure 2 is a cross section of the same.
Figure 3 is a cross section of a sheet of compressed absorbent cotton coated with
starch on one side only.
The package consists of a thin homogeneous bat of well carded absorbent
cotton, A, that may be medicated with antiseptics such as iodoform, carbolic acid,
corrosive sublimate, etc. Said bat of cotton has either one or both surfaces, A'
coated and impregnated with a thin solution of starch or other glutinous or adhesive
gum that extend substantially the whole distance within its body, by suitable means.
The thin coating of starch causes a certain thickness of the superficial fibres of the
bat to remain united together, and said bat of absorbent cotton with its coated and
impregnated surfaces is subjected to a moderate pressure between rolls preferably
covered with canvas or wire cloth, that causes the solution to sink deeper, gives a
pebbled appearance, and reduces the thickness of the bat to that of thick blotting
paper and nearly its consistency, although its body within the two surfaces, A³,
having but little starch incorporated within, retains the appearance of a well carded
but compact bat. In the drawings the parts are slightly magnified, and in Figure 1
the starched surfaces, A', are shown partly pulled apart from each other to show
the impregnation with gum, sizing or starch, of the top and bottom surfaces.
In Figure 3, only one surface is shown impregnated with sizing or starch.
The lint package above described differs from ordinary cotton batting in, first,
the material used, which is highly absorbent cotton; second, in the thickness given
to the bat; third, in the relative proportion of the starch impregnated surface or
surfaces to the interior thickness of the body of the bat, said proportion being
nearly the whole body; fourth, in the felted and compact form of the material that
permits a large sheet thereof to stand upon its edge without having its upper part
topple over; and fifth, in the indented or pebbled appearance given to the starch-
impregnated surfaces. Consequently there is no difficulty in distinguishing the
above prepared and described absorbent lint package from the heretofore surface
glazed and prepared cotton in common use.
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. As a new article of manufacture, an absorbent-cotton lint package consisting
of an homogeneous absorbent-cotton bat formed in a thin sheet, having one of its
surfaces impregnated with a solution of starch pressed therein in the proportion to
the thickness of the package, substantially as described.

page_text: 2. As a new article of manufacture, an absorbent-cotton lint package consisting
of an homogeneous absorbent-cotton bat formed in a thin sheet having its top and
bottom surfaces impregnated with an adhesive solution pressed therein and
indented or pebbled, substantially as described.
