Improvements in the Manufacture of Double or Lined Fabrics.
I, JULES ROUSSEAU of Sedan, France, 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 :-
Hitherto in order to give thickness to fabrics it has been usual to add by weaving
to the single fabric a back warp or weft and sometimes two in order to form a
second fabric which has been connected to the first by tying or binding points.
These binding points can only be placed at intervals in accordance with the draught
and while constituting only an imperfect connection between the two fabrics they
have the great drawback that they produce faults in the fulling.
In order to obviate this objection and with the object of allowing the thickness
of a fabric to be regulated as required, I unite the two fabrics whether woven
simultaneously without the tying or binding points, or manufactured separately, by
a layer of carded wool interposed between the two fabrics and in which they
become mixed so as to form one homogeneous body with the intermediate wool.
In order to effect this union of the two fabrics with the wool I make use of the
fulling processes usually employed for felts and cloths. During the fulling the
threads of the first and second fabrics become perfectly united in the layer of wool
which also becomes united to the fabrics. I thus obtain a compact and strong
body which has neither the drawbacks of felts nor the faults of double fabrics
produced by weaving.
In some cases instead of employing two fabrics as above described and uniting
them by an intermediate layer of carded wool as explained, I employ a single fabric
and line or back it with felt. In this way the fabric is all left visible so that it can
be subsequently given any required dressing or finishing. The canvases which
have up to the present been added to felts have always by the fulling operation
become hidden in the body of the felt and therefore have never served to form at
the back of the felt a fabric that could in any way be dressed.
I do not employ
a canvas in this manner but I obtain a dressed fabric made thick by lining or
backing it with felt.
My new methods of manufacture have the advantage that they allow of fabrics
being made of a thickness not hitherto attained since the layer or thickness of wool
can be increased at will; while by doubling or lining very light fabrics in
accordance with my method they are given great strength.
The invention is more particularly applicable to the manufacture of double or
lined fabrics of wool. To apply it to fabrics of silk, flax, cotton or other textile
material it suffices to give them a weft of wool to make the fulling perfect.
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 [
claim is :-
1. The method or process herein before described of manufacturing double or
lined fabrics by combining with two fabrics which will respectively form the two
faces of a double fabric, or with a single fabric which will constitute one of the
faces of the final fabric, a layer of carded wool which is in the one case interposed
between the two fabrics, and in the other case is applied to one face of the single
fabric, the whole being subsequently fulled in order to effect the union of the
several parts and produce a compound fabric which can be afterwards dressed or
finished in the ordinary manner so as to obtain a dressed or finished fabric wh.cb
has been made thick by a filling or lining, substantially as set forth.
2. The new double fabric or lined fabric hereinbefore described in which two

page_text: fabrics form the two faces of a filling of carded wool interposed between them, or
in which one fabric forms one face of a layer of carded wool, the whole being
united together by fulling, as set forth.
Dated this 24th day of March 1892.
