Complete List of Raw Cotton Parameters

Raw cotton or ginned cotton can be described using a variety of parameters. Here is a list of some common parameters used to characterize cotton:

  1. Staple Length: It refers to the length of the individual cotton fibers. Staple length is usually measured in millimeters (mm) or inches (in).
  2. Micronaire: It is a measure of the fineness of the cotton fibers. Micronaire values range from 2.5 to 7.5, with lower values indicating finer fibers.
  3. Fiber Strength: It is a measure of the force required to break a bundle of cotton fibers. Fiber strength is typically measured in grams per tex (g/tex).
  4. Color Grade: It refers to the color of the cotton fibers. The color grade scale ranges from 1 (white) to 8 (light gray).
  5. Trash Content: It refers to the non-lint material present in cotton bales, such as leaves, stems, and other foreign matter. It is typically measured as a percentage by weight.
  6. Moisture Content: It refers to the amount of water present in the cotton fibers. Moisture content is typically measured as a percentage by weight.
  7. Uniformity Index: It is a measure of the consistency of the cotton fibers in terms of length, strength, and micronaire.
  8. Fiber Fineness: It refers to the diameter of the individual cotton fibers. It is typically measured in microns.
  9. Seed Coat Neps: It refers to the small knots or bumps that can occur on the surface of cotton fibers due to the presence of seed coat fragments.
  10. Trash Grade: It is a measure of the amount of foreign matter present in the cotton bales, including leaf, bark, and other debris. The trash grade scale ranges from 1 (cleanest) to 7 (most contaminated).

These parameters are used by cotton buyers and sellers to determine the quality and value of cotton.
