Improvements in the Manufacture of Double Plush Fabrics
I, GEORGF FREDERICK REDFERN, of the Firm of G F Redfern & (o,
The General Patent Office, No 4 South Street, Finsbury in the County of
London, Patent Agents, do hereby declare the nature of this invention (a com-
munication to me by Christian Mengen, of Vierse, Westphalia, in the German
Empire, Weaver) and in what minner the same is to be performed, to be
particularly described and ascertained in and by the following statement
This invention relates to an improved manufacture of double plush fabric from
mohair yarn
Plush mide from mohair yarn and used for covering furniture must be firmly
woven to enable it to withstand for any length of time the wear to which it is
subjected
Mohair yarn, being very fibrous and not very flexible, has up to the present only
been successfully woven into plu h of this description by hand and the plush
produced has therefore been ielitively dear
Many attempts have been made to produce this fibric by mechanical means but
hitherto this object has not been successfully attained by using known methods of
binding, for even if by these well known methods a fabric can be produced with
binding of the pile warp this fabric is wanting in durability because the pile waip
is not firmly woven in and can therefore be easily withdrawn from the fabric as it
is only held by one weft thread and in practice this is found to be a great objection
such for example when plush is stretched over shup edges and rubs against them,

frayed and unsightly
Plush fabric manufactured according to my invention possesses the advantage
that the pile warps are very firmly bound in the body by means of four weft threads
thereby rendering the fabric very strong
To enable my invention to be fully understood I will describe it by reference to
the accompanying diawings, in which
Figure 1 shews an example of the ordinary hand woven fabric
Figure
an example of a well known method of manufacturing plush fabuc
Figures 3 and 4 represent my improved double plush fabric illustrating the
essential differences between it and the two kinds of fabric shewn in Figures 1
and 2
In Figure 2 which illustrates a well known method of manufacturing double
plush fabric by the use of one shuttle the double lines a, a and a', a¹ represent the warp
threads, the full and dotted lines b, the pile warps of the double fibric, whilst
c, c1epresent the weft threads
The shuttle forms for picks for the upper fabric and four for the lower fabric
al crnately so that the operation takes place is follows 1, 2, 3, 4 above 5 6, 7, 8

The warp is made to cover the pile warp on the underside of the finished fabric
as shewn

double lines a, a and a', a' repre ent the warp threads, the full and dotted lines b, b¹

operation takes place as follows

1,2 above 3, 4 below, and then 5, 6 again at the top and so on until the set of 16
is finished
The binding is the same for both fabrics and the pile warp passes between two
warp threads
In the modification shewn in Figure 4 the same binding is effected by means of
two shuttles
As two shuttles are used at the same time eight picks are made for the upper
No further description of
fabric and at the same time eight for the lower fabric
this figure is required as that used in describing Figure 3 will also apply to this
figure
If this double fabric be cut asunder it is practically impossible to draw out the
pile warp
om the fabric because it is firmly held by the warp and weft threads
and cannot be drawn out in any direction In the method illustrated in Figure 2
on the contrary in which the pile warp is only held by one weft thread it can be
removed with facility in the direction of the arrow 3 and which occurs in fact when
the fabric is rubbed on a sharp edge
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 The improvements in the manufacture of double plush fabric of mohair
Jarn substantially as hercinbefore described and illustrated in the accompanying
drawing
2 Double plush fabric or mohair yain manufactured substantially as herein
described
