How is Cotton Produced? Video Lecture | Advance Learner Course: Science Class 5

cotton is a shrub native to the Americas
Africa in India like many other plants
wild cotton developed fibers around its
seeds to better catch the wind and help
disperse its seeds farther these fibers
have been used to make clothing for
millenniums as far back as 5000 BC
however the laborious process of
removing seeds from the cotton fibers
prevented it from ever becoming
economically viable that changed in 1793
with the invention of the cotton gin
which automated the separating process
it made cotton a largest exported crop
in the u.s. while creating a large new
market the unintended consequences of
the cotton gin inadvertently led to the
increase of slavery in the US and
ultimately the American Civil War
cotton requires a warm dry climate with
lots of sunshine which limits its growth
to the southern us an area referred to
as the Cotton Belt which means I'll have
to take another trip for this material
this time the largest cotton growing
region in the world West Texas all right
so after early flight this morning I'm
in West Texas about 80 miles south of
Lubbock's I have never actually seen
cotton field before so this just looks
weird it bunch of little shrubs just
growing cotton balls before I even
arrived I learned that the timing of the
cotton harvest is highly dependent on
the weather arraigned several days
before I got there threatened to prevent
me from being able to pick anything you
like I picked a lot more than just this
after collecting my cotton by hand
I was taken over to another field where
the farmers were actually machine
harvesting here I got to see the amazing
speed which an entire field can be
harvested in a day by just a handful of
people hoping for the chance to drive
when the Cotton Pickers I thought they
might let me take a turn but
unfortunately it went such a rush to get
the field pick by the end of the day I
didn't even have a chance to ask the
three cotton picker machines go row by
row clearing the cotton ones full they
dumped their load into the following
Bowl buggy the bull buggy then dumps the
cotton into the cotton module builder
which uses the hydraulic compactor to
compact the cotton into one solid module
once full the module builder pulls away
revealing the cotton module ready for
pickup where I'll be taken to the cotton
gin next at the cotton gin I was given a
tour of the process by which the cotton
lint is separated
the ginger Isaac odd separates any dirt
sticks or other foreign objects and uses
small sharp blades so grab the cotton
fiber pulling it from the seeds
separating them
then the isolated cotton fibers are
collected one Melinda bails and shipped
out
the con seats are kept by the cotton gin
is payment and used for making cotton
seed oil nuestros able to see the full
size one in action I know they're this
small CI one so I can gin just my pod
all right so after using the khanjan
several bags of cotton separated cotton
seeds and all the other junk from it now
I just have just the part that I want
the cotton lint should be ready to be
spun into a fabric next unfortunately I
never ended up having the chance to
drive one of the cotton machines really
hoping to it's kind of a childhood dream
of mine but uh I was able to find the
next best thing
well there I wanted to talk to you for a
couple of minutes about the history of
cotton harvest
ready to the drop
ready
