AN IMPROVED "PACK" OR BAG FOR HOLDING AND CONVEYING WOOL
Year: 1884

page_text: I, SAINT JOHN VINCENT DAY of 115 St Vincent Street Glasgow, in the County
of Lanark North Britain Civil Engineer and Patent Agent do hereby declare. the
nature of the said Invention for "AN IMPROVED "PACK" OR BAG FOR HOLDING
AND CONVEYING WOOL" to be as follows:
This Invention which relates to an improved "pack" or bag made of jute for
holding and conveying wool, has for its object to prevent shreds of the jute fibre
of which such "packs" or bags are made from becoming separated from the jute
and mixed with the wool.
"
The attainment of the foregoing object has long been a desideratum in "packs
or bags for the packing and conveying of wool as the fibre of the jute of which
the said "packs" or bags are made is extremely tender and throws off with the
slightest rubbing a large quantity of shreds which adhere to the greasy wool-The
jute cloth also tears and unweaves itself each time the bales are handled so that at
last the raw wool has mixed up with it fibres or shreds which hitherto it has proved
impossible to pick out for the reason that the eye cannot easily detect them.
These fibres or shreds of jute become further mixed with the wool in carding,
combing, spinning and weaving operations without exhibiting their presence but
in the operations of dyeing woollen yarns or fabrics they become detected as they
do not take up the dye in the same proportions as the wool itself, the shreds or
fibres of jute assuming a darker hue than the wool so that it is only at very
considerable expense the jute fibres or shreds can be removed from yarns or fabrics
in the spun or woven state.
In order then to prevent the shreds or fibres of jute from separating themselves
from the twilled cloth of which such "packs" or bags are made the twilled side,
that is to say, the side of the cloth on which the warp yara preponderates is used
for the inner side of the said "packs" or bags and in order to lay the fibres or
shreds of the jute cloth the interior of the said "packs" or bags is sized or starched
and the exterior may also be sized or starched to prevent the said "packs" or bags
from external deterioration.

page_text: I, SAINT JOHN VINCENT DAY, of 115 St Vincent Street, Glasgow, in the
County of Lanark, North Britain, Civil Engineer and Patent Agent do hereby
declare the nature of the said Invention for "AN IMPROVED PACK OR BAG FOR
HOLDING AND CONVEYING WOOL" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The said Invention which relates to an improved "pack" or bag made of jute
for holding and conveying wool, has for its object to prevent shreds of jute fibre of
which such packs or bags are made from becoming separated from the jute and
mixed with the wool.
The attainment of the foregoing object has long been a desideratum in "packs"
or bags for the packing and conveying of wool, as the fibre of the jute of which
said "packs" or bags are made is extremely tender and throws off with the slightest
rubbing a large quantity of shreds which adhere to the greasy wool-The jute
cloth also tears and unweaves itself each time the bales are handled so that at last
the raw wool has mixed up with it fibres or shreds, which hitherto it has proved
impossible to pick out for the reason that the eye cannot easily detect them.-
These fibres or shreds of jute become further mixed with the wool in carding,
combing, spinning and weaving operations without exhibiting their presence, but
in the operations of dyeing woollen yarns or fabrics, they become detected as they
do not take up the dye in the same proportions as the wool itself, the shreds or
fibres of jute assuming a different hue to that of the wool, so that it is only at very
considerable expense the jute fibres or shreds can be removed from the yarns or
fabrics in the spun or woven state.
"
In order then to prevent the shreds or fibres of jute from separating themselves
from the interior surface of the cloth (preferably twilled cloth) of which such
packs" or bags are made, the inner or twilled side, that is to say, the side of the
cloth on which the warp yarn preponderates, is used for the inner side of the
said "packs" or bags, and to lay the fibres or shreds of the jute cloth, the interior
of the said "packs" or bags is sized or starched. The exterior may also be sized
or starched to prevent the said "packs" or bags from external deterioration.
The sizeing or starching of the cloth may be effected in any convenient manner,
such for example as by passing it over or through what are known as damping or
sprinkling machines, in which liquid size or starch is contained; the means by
which the size or starch is applied to the cloth forming no part of this Invention ;
it being explained that any of the well-known kinds of mechanism for sizeing or
starching fabrics may be used for the purposes of this Invention.
After the cloth is sized or starched, the cloth is preferably passed between rollers
operated upon by pressure so as to squeeze the shreds or fibros down into the
fabric or body of the cloth whilst wet with the size or starch, and when dry the
size or starch retains the shreds or fibres on or in the said fabric.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
"
In the construction or manufacture of " packs or bags of jute for holding and
conveying wool, the using of the twilled side of the cloth for the interior of the
said "packs" or bags, and laying the fibres or shreds of the jute cloth at the

page_text: interior surface of the said "packs" or bags, or at both the interior and exterior
surfaces thereof, by sizeing or starching the same, thereby causing the said fibros
or shreds to adhere to the surface or surfaces or body of the said cloth or fabric as-
hereinbefore set forth.
