DESCRIPTION

1.1 This test method covers the determination of linear density (gravimetric fineness hereafter stated as fineness), maturity, micronaire, and ribbon width of cotton fibers from a loose, chemically untreated sample taken before harvest, during ginning, during mill processing or unraveled from raw (undyed) yarn or fabric.

1.2 This test method requires the use of an integrated instrument, for example, the Cottonscope (see Fig. 1), that measures the maturity, fineness, ribbon width, and micronaire of cotton fiber.2
