What is the process of Spinning? Video Lecture - Class 6

hello friends this video on fiber and
fabric part 5 is brought to you by exam
feel calm no more fear from example so
the next step that comes is spinning so
it is a process of making yarn from
fibers so what is yarn so you see fibers
and like this they do not have a
specific shape it's like you know kind
of hollow at the same time no specific
shape and it is not arranged in a proper
way
so when busy yarn what is yarn yarn is
nothing but you would have seen them
kind of thread-like structures which are
like rolled over a particular thing so
roll in up and then organize to be so
that they do not get tangled for example
have you ever seen the need the needle
and the thread so the threads are like
rolled in a specific pattern so that if
it just doesn't get tangled similarly
when you look at the goalie arms so
there are so this is how the wool yarn
looks like so the bullying fibers are
like organized in a specific pattern and
that's how it is roll that cap so it
helps the rule to be utilized later in a
nice swing so it prevents there from
getting entangled now how do we get a
yarn like this from a fiber like this
which is so disorganized so the basic
thing that we do during spinning is we
stretch the fiber and at the same time
we twist them also so this is when you
stretch the fiber you get a long thread
like structure and in the same time you
keep rotating it so you know it's kind
of getting twisted and getting stretched
both are happening at the same time and
this is how you get a thread like
structure whether you talk about the
cotton threads you talk about the wool
you talk about the silk thread so
everywhere you have a thread like
structure so this is how the thread like
structure is formed and then with these
thread-like structures you will later
get the fabric now the question is how
do we boot this this doesn't seem to be
simple like you have so much of your
fiber and how do we just manually
stretch and twist these fibers
inform searching yards that that sounds
really insane and that sounds really
impossible well it is not impossible but
yes to make this tedious task simple we
make use of machines but in the machines
also the basic fact that the basic thing
that needs to be done is they need to be
stretched last twisting so stretching
and twisting needs to happen at the same
time and that is how we spin the fibers
now some of the devices which are
commonly used for spinning are charka so
Chara is a very popular device and which
was very popular which was made popular
by Mahatma Gandhi during independence so
when he was he was ahead with the
independence revolution in our country
he encouraged people to wear clothes
which are like made in India so he
encouraged people to wear clothes of
hand-spun yarn so how did he spun the
yarn I mean how did he make use of the
fibers to make clothes so he made use of
this machine which is like a spinning
wheel you see a big wheel and the wheel
keeps like spinning so here the five
hood is arranged in such a way that the
fiber gets stripped stretched and at the
same time as they will move so it also
gets twisted so the twisting and
stretching happens because of this
device and that's how you see you he is
holding something in his hand and
whatever thread is coming out of it that
is getting rolled on on this so that's
how you make the yarn so basically you
started with something like the cotton
fibers which I showed you in one of the
previous slides or in which like there
is no like appearance so there you
didn't have any thread or anything but
now because of this charkha you are able
to get a thread and then you are rolling
the thread on something which is which
gives rise to the formation of yarn
so this charkha appeared in China in the
11th century but later with like more
technological advancements it was
replaced with the hand spinning spindle
now this chair has like quite huge and
it is not portable so and it's not very
easy to carry it from one place to
another so that shows where some of the
disadvantages of Charcot so later it was
replaced with something called tacky so
this tack knee is nothing but it is like
a spindle so you see it looks so handy
you can just hold it in your hand and
you can just do the spinning yourself so
it is a small spindle which is used for
spinning short fibers like cotton now it
cannot be used for long fibers but for
short fiber especially cotton in fact
the child car was also used chiefly for
cotton so that is this technique would
be a good replacement for the charka
because of its convenience so another
important thing is this spindle this
chart aptly it spins very fast it spins
so fast that you know it does your job
very quickly so what do we want to do
you see here so this is how the cotton
fibers are right not organized not in
the form of threads now when you stretch
them and you put it in the spindle so as
the spindle rotates like this and it
rotates very fast now as it rotates what
happens these thread-like structures
they kind of get rolled over it and
that's how you get it in the form of
yarn so that's how the yarn formation is
taking place so it is very very
efficient in spinning short fibers like
cotton so it has more advantages than
the Charcot for example it is handy it
is very fast efficient inexpensive and
because of so many advantages it kind of
took over the charkha so these are some
of the ways by which cotton spinning is
done so the first step was gaming where
the seeds are removed from the fibers
the second step where the fibers are
stretched to form thread light struck
that's how they wear the yarn formation
takes place now once you have the yarn
then it becomes easier to kind of you
know assemble the threads to form a
fabric thank you
