3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Cotton fiber cell wall relative to the degree of development.
3.2
The actual cotton fiber cross-sectional area of the cell wall area of a circle with the same perimeter ratio.
3.3
Cotton fiber cell wall thickness increased to 0.577 arbitrarily selected equal to the increase in the standard thickness ratio.
3.4
The average percentage of mature fibers comprise fibers of the total number of roots.
3.5
It represents an indicator of the cotton fiber maturity. According to the Department of the ratio of cotton fiber cell wall thickness and cavity width fixed for the corresponding value. ratio
The smaller the coefficient, the greater maturity, represents the more mature fibers.
3.6
Lateral wall thickness by optical microscope observation cotton fiber convolutions flattened segment.
3.7
Lateral observation through an optical microscope cotton fiber convolutions flattened sections of wall remaining cavity width.
