Grading Of Cotton Fiber || Different Cotton Grading System

Cotton Fiber

Cotton fibers grading is done depending on their physical characteristics such as length, strength, fineness, maturity, trash content, etc. This classification is called the grading of fiber.

Cotton fibers grading depends on the trash content of the cotton fiber. Except for fiber, other impurities and dust such as broken leaves, broken seeds piece are called the trash of the cotton. If one wants to produce well-qualified yarn he needs to remove all trash and short fiber from the cotton fiber. So, it is required to know the quantity of trash in the cotton. To measure the trash content in the fiber an instrument is used called Shirley Analyser.

  1. I am very curious about your statement: “Grading of US Cotton: This grading is done from upper quality to lower quality.”

    Pleas explain where, as you put it, “this grading is done” which includes the odd term “Middle Fair.” I grew up in cotton growing country, and had extensive experience with cotton, from picking it (including dragging bags through fields, picking by hand) to baling it (Literally. Operating the press in a cotton gin which takes the cleaned cotton and produces 500 pound bales.) and, of course, wearing it.

    In my entire, blessedly long, life I never encountered the term “Middle Fair” before today, on this Web site.

    Where did it come from, and can you cite an authoritative Non-Internet source?
