Results are reported in terms of grams per tex to the nearest tenth. A tex unit is equal to the weight in grams of 1,000 meters of fiber. Therefore, the strength reported is the force in grams required to break a bundle of fibers one tex unit in size. Leaf refers to small particles of the cotton plant's leaf which remain in the lint through the ginning process. Leaf grades are determined by the classer and are identified as numbers 1 through 7, all represented by physical standards.
Extraneous matter is any substance in the cotton other than fiber or leaf.
Examples of extraneous matter are bark, grass, spindle twist, seed coat fragments, dust, and oil. The amount of extraneous matter in the cotton is reported as level 1 and level 2, with level 2 indicating the heavier contamination. The HVI assigns the remarks code 75 where applicable. Classers identify other special condition cotton. Some of these items cause processing problems and lower yarn quality.
