Resumo
Cotton is the most important natural source of fiber in the world, with the largest volume
of world production, besides being the largest source of raw materials of the textile
industry, still provides as the grains by-products that are rich in oils and residues are
protein-rich employees mostly in animal feed. Cotton production in Brazilhas expanded
in the State of Mato Grosso, where growers have found large tracts of land and
favorable conditions for the development of culture, resulting in the rapid growth of the
area produced. The State of Mato Grosso is responsible for the whole fibre produced
in Brazil 68% of this fibre is produced in Mato Grosso, giving it a leading position
worldwide. The characterization of the quality of the fibre produced in commercial plot
is important to determine the qualitative variations within a single site enabling the
farmer to search for areas that allow the less variability of fiber quality, enabling the
adoption of actions that raise the homogeneity of the plot producing higher quality
fibersthat offer better remuneration to the producer at the time of sale. The best quality
of fiber is set at the moment the ball opens at the end of the cropcycle, the actions
taken post harvest should be made properly to prepare these fibers for industrialization,
while must preserve the original characteristics of the fiber.While the fiber remains in
the field she becomes sensitive to environmental factors that are detrimental to their
quality characteristics. To be avoided these potential damage the harvest should be
done in short period of time, making it important to the determination of a suitable
machines depending on the amount of area to be harvested, in typical conditions of
cultivation in Mato Grosso, obtained 60% collection efficiency and operational
efficiency of approximately 67.2%. After harvesting andprocessing, spatial variability
of fiber quality is completely mischaracterized, mostly by homogenization arising out
of the operation mode of the harvester and the waythe processing occurs. When the
equipment used in processing are appropriately regulated cannot detect significant
changes of qualitative characteristics of the fibers.
