chester, in the County of Lancaster, Manager, and SAMUEL CAREY ROGERS
GAUNTLETT, of Yerbury Mills, Trowbridge, in the County of Wilts, Manufac-
ture, do hereby declare the nature of this invention to be as follows
1
This invention relates to the manufacture of an improved yarn and has for its
object to so treat and prepare jute as to render same capable of, and suitable for,
being mixed and combined with other fibre o fibres such as cotton wool, silk,
etc., but pumarily has for its object to produce a yarn of cotton and jute advan-
tageously jute waste and consists of a process or system of treatment of the jute
or Jute waste alone and then of the jute and other fibre or fibres combined to
finally produce a yarn according to this invention having many advantages
According to our present invention we proceed as follows,
We take Jute or jute waste in the usual or any suitable form in which same
may be found in commerce and subject same to the action of a disintegrating
carding or opening machine such for instance as the machine for which we
received the grant of Letters Patent No 19872 of 1896 or other suitable machine
for the purpose of thoroughly breaking and opening the material and removing
to some extent non-fibious material, dust, duit, etc
Next wo take the jute fibre in this "open" condition and subject same to suit-
able chemical treatment to ungum same and remove as far as possible or to a
large extent the tannic-like substances from the cellulose as also any of the bark
o skin of the plant so that when the fibre comes from this bath or treatment
(and after being subjected to an acid or neutralising treatment) the fibre is now
in a very soft and open condition and is now capable of being and adapted to be
mixed with cotton or other fibre o fibres as follows and for the sake of example
we will describe the production of a yarn consisting of jute and cotton according
to our present invention.
The jute after passing through the alkalı and acid treatment as aforesaid and
either with or without passing through a soaping or analogous process at this
stage to rende same pliable (or such soaping process may take place at a later
stage if desired) is then died and if necessair (that is if the fibre is found to be
matted or to require it) it is then subjected to a carding or opening operation or
may be put duect through a cotton scutching machine of the present well-known
type or cotton machinery of the character known as a condenser" the object of
this treatment being to now form the jute into a lap
"
We now take this lap of jute and together with a lap of cotton (in any suitable
proportions according to the object for which the yarn is required) pass these
into and through a lap machine of any suitable chai acter for instance the well-
known cotton lap machine to mix the said fibres together and produce a lap
from such mixed fibies.
This lap of mixed fibre (jute and cotton) is now passed through a carding

page_text: engine and thereby the now thoroughly mixed and incorporated fibies are further
cleaned and reduced to a short staple and leave this machine in the form of
sliver and this sliver we now pass through the ordinary (or any suitable) slub-
bing and roving operations; or instead of passing the lap of mixed fibres through
the last-named carding machine we may pass said lap through a
condenser
(of the aforesaid character) by which means we obtain the fibre in the form of
10ving direct

The roving thus obtained is now spun into yarns of suitable counts by any
suitable cotton spinning machinery and the yain wound into cops oi outo
bobbins etc single or otherwise may be used for any purposes to which same is
applicable for instance in place of cotton yarns

Having prepared jute in the manner hereinbefore set forth-instead of mixing
same with cotton alone we may nux same with other fibre or combinations of
fibres and in such cases ceitam modifications may be necessary for instance in
the case of jute prepared according to our present invention being mixed with
wool we should proceed as follows.-
We take the jute fibre, after same has been subjected to the alkah and acid
processes and died, and pass same through a carding engine to form a lap and
then auch lap of jute 18 fed with a lap of wool (in suitable proportions) into
woollen condensing engines of the well-known type and thereafter the treatment
of the combined fibres would be the same as or similar to that employed in the
treatment of wool alone, or if desired we may combine and mix the jute with
the wool in other suitable manners for instance the jute after same has been
died instead of being first formed into a lap may be fed together with the wool
into a "devil" or "tucker" or passed through a wool scribble and thereafter
the combined fibres are subjected to a similar treatment as that of wool alone.
The mixture of the jute prepared according to this invention with silk is
similar or analogous to that described with reference to its mixture with wool

The Manufacture of an Improved Yarn.
We, JAMES LEECH BOTTOMLEY, of The Mound, Clifton Junction, near Man-
chester, in the County of Lancaster, Manager, and SAMUEL CAREY ROGERS
GAUNTLETT, of Yerbury Mills, Tiowbidge, in the County of Wilts, Manufac-
turei, 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.-
This invention relates to the manufacture of an improved yarn and has for its
object to so treat and prepare jute as to render same capable of, and suitable for,
being mixed and combined with other fibie or fibres such as cotton, wool, silk,
de, but primarily has for its object to produce a yarn of cotton and Jute advan-
tageously from jute waste and consists of a process or system of treatment of the

page_text: Jute or jute waste alone and then of the jute and cotton combined to finally pro-
duce a yarn according to this invention having many advantages
According to our present invention we proceed as follows.-
We take jute or jute waste in the usual or any suitable form in which same
may be found in commerce and subject same to the action of a disintegrating
carding or opening machine such for instance as the machine for which we
received the giant of Letters Patent No 19872 of 1896 or other suitable machine
for the purpose of thoroughly breaking and opening the material and removing
to some extent non-fibrous material, dust, dirt, etc
Next we take the jute fibre in this "open" condition and subject same to suit-
able chemical treatment to ungum same and remove as far as possible or to a
large extent the tannin-like substances from the cellulose as also any remaining
bark on skin of the plant so that when the fibre comes from this bath or treat-
ment (and after being subjected to an acid or neutralising treatment) the fibie
18 now in a very soft and open condition and is now capable of being and adapted
to be mixed with the cotton for instance we may advantageously proceed us
follows.-
We take the jute thus disintegrated and opened and subject it to the action
of alkaline solutions in either of the two following ways.-
(1) We boil (say from 6 to 12 hrs as the quality of the fibre may require) the
fibre with a solution of caustic soda or carbonate of soda or silicate of soda ni
mixture of these containing soda (Na,O) equal to say 1% on the solution
(2) We steep (say from 2 to 3 hrs as the quality of the fibre may requie) the
fibre in a solution of caustic soda of concentiation equal to from 10 to 20% NaOH
By the former treatment the fibie is cleansed from adventitious matter and is
also partially resolved ze by separation of its constituent fibrils or ultimate
fibres. In the latter treatment the last-named effect is produced in greater
degree.
After either treatment the fibre is washed to thoroughly remove the soluble
impunity and the residue of alkalı After such thorough washing it may be
bleached if required by treatment with any of the well-known bleaching agents
From the bleaching treatment it is again thoroughly washed and then tieated
with dilute acid in the cold
From the latter the fibre is very thoroughly washed
Lastly it is deprived by squeezing or by centrifugal action from the excess of
water and dried by exposure to heat upon a suitable diying floor on machine
If necessary (for instance if the fibre is found to be matted) it 18 subjected to
a carding or opening operation or may be put duect through a cotton scutching
machine of the present well-known type of cotton machinery of the charactei
known as a cotton waste breaker card the object of this treatment being to now
form the jute into a lap
We now take this lap of jute and together with a lap of cotton (in any suitable
proportions according to the object for which the yarn is required) pass these
into and through a lap machine of any suitable chai acter for instance the well-
known cotton lap machine to mix the said fibres together and produce a lap
from such mixed fibres.
This lap of mixed fibre (jute and cotton) is now passed through a carding
engine and thereby the now thoroughly mixed and incorporated fibres are further
cleaned and reduced to a short staple and leave this machine in the form of
sliver and this sliver we now pass through the ordinary (or any suitable) slub-
bing and roving operations; or instead of passing the lap of mixed fibres through
the last-named carding machine we may pass said lap through a finisher calding
engine and condenser machine (of the aforesaid character) by which means we
obtain the fibre in the form of loving duect
The roving thus obtained is now spun into yains of suitable counts by the
ordinary or any suitable cotton spinning machinery; and the yarn (wound into

which same 18 applicable for instance in place of cotton yarns
If desired the mixture as above may be bleached or dyed (either in the bank
or cop etc or when woven into a fabric) in any well-known or suitable mannci
or
or if desired the jute may be bleached and dyed before same is mixed with the
cotton as aforesaid.
Having prepared jute in the manner herein before set forth-instead of mixing
same with cotton alone we may mux same with other fibre or combinations of
fibres and in such cases certain modifications may be necessary for instance in
the case of jute prepared according to our present invention being mixed with
wool we should proceed as follows:-
We take the jute fibre-after same has been subjected to the alkali and acid
processes and died and pass same through a scutcher or lap machine to form a
lap and then such lap of jute is ted with a lap of wool (in suitable proportions)
into woollen first carding or intermediate engines of the well-known type and
thereafter the treatment of the combined fibres would be the same as or similai
to that employed in the treatment of wool alone, or if desired we may combine
and mix the jute with the wool in other suitable manners for instance the jute
after same has been died instead of being first formed into a lap may be fed
together with the wool into a ** devil" 01 "tucker" machine or passed through
a wool scribbler and thereafter the combined fibres are subjected to a similar treat-
ment as that of wool alone
The mixture of the jute prepared according to this invention with silk is
similar or analogous to that described with reference to its mixture with wool
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim 18.—
1 The here-described process for the manufacture of yain from jute and
cotton which consists in preparing jute or jute waste by first subjecting same to
the action of a machine to bieak and open same then subjecting same to chemical
treatment in the manner and for the purposes specified and after drying-and
either with or without then subjecting same to a carding or opening operation-
next passing same through a cotton scutcher, lap machine or breaker card, to form
the jute into a lap next combining this lap of jute with a lap of cotton in suit-
able proportions and passing same together though a lap maclune to mix the
said fibies together and produce a lap therefrom, next passing this lap of mixed
fibres through a carding engine to produce a sliver and then passing this sliver
either through slubbing and roving machinery or through a finishing calding
engine condenser and finally spinning the 1oving thus obtained into yains sub-
stantially in the manner and for the purposes heieinbefore described

drying then passing same through a scutcher or lap machine to form a lap and
then such lap of jute is fed with a lap of wool into woollen fist carding on inter-
mediate engines and thereafter the combined fibres are treated in the same of
similar manner to that employed in the treatment of wool alone substantially in
the manner and for the purposes described.
