(Figure 2) This image is of a picker machine collecting the fully grown cotton plants.
Cotton is grown in warm
temperatures, typically during the early spring season. The land
is ploughed and the soil is broken into rows forming seedbeds all in
preparation for planting cottonseeds. Mechanical planters are used to plant the
cottonseeds into the soil. This process is called seeding – machine planters
tunnel small holes into the ground, release the necessary amount of seeds into
each hole and finally, conceal the hole with a pack of dirt above it. On
average these machine planters can cover as many as twelve rows at one time. Machine cultivators are used
to pull uprooting weeds that will possibly compete with the cotton plants for
soil nutrients, sunlight and water. This process is called hoeing. The plants
are irrigated and fertilized as needed over the next few weeks. About a month or so into
planting the cottonseeds – a white bloom begins to form. This white bloom gradually
turns red and dies after approximately three days – (all the petals shrivel up
and simply fall). This allows for the cotton bolls to develop from the fruit
that remains. Afterwards: fibers from the inside of the cotton bolls grow and
expand, eventually splitting the boll a part – the end product that springs
outward is cotton. The plants are defoliated only if they are to be picked up
by a machine. Defoliation is a process whereby chemicals are showered above the
plants to allow their leaves to fall off, lessening the chance of the leaves
becoming tangled in the machine. A machine – either a picker or a stripper – is
used to collect all the plants. In developing countries, cotton is often
harvested by hand. The cotton collected from the harvesting is packed and
stored into modules. These modules are then taken to the gin. The role of the
gin is to separate the cotton fibers from the seeds. The cotton fiber (lint;
without a seed) is cleaned of any debris and is compressed into bales. These
bales are then transported to textile mills. These bales are then opened at the textile
mills and the lint is mixed and further cleaned by means of blowing and
beating. This cotton enters a carding machine and is further cleaned once more
for the last time. The carding machine also straightens and softens these
fluffed-up fibers. The outcome of the work of the carding machine is an
untwisted rope called silver. Spinning machines yarn the fibers in the silver. Machines
called looms weave the cotton yarn at fast speeds. The final product - a woven
fabric entitled grey woods - is sent to the finishing plant where it is
bleached, pre-shrunk, dyed and printed. Home products and clothing can then be
made from this woven fabric.
