Selected 13 bales are analyzed using different fiber maturity measuring methods (New FIAS, AFIS, and Cottonscope). Maturity distributions of the bales 3097, 3142, and 3051 reported by three methods are shown in Figure 3, Figure 4, and Figure 5 respectively. Even though same bales were used for comparing the maturity distributions, a distinct difference is observed between the maturity distributions. The shape of the New FIAS maturity distributions are similar with the distributions from the AFIS however, are deviated more towards the left side. Similarly, the distributions from the Cottonscope are different with the distributions from the New FIAS and have deviated towards the right side. The distributions from the New FIAS and AFIS are relatively peaked compared to the distributions from the Cottonscope.
Means and skewness values of the distributions are calculated and provided in the
Table 1. Skewness is calculated to determine the symmetry of the distributions. We can observe that for the same bale different methods provide different means and skewness values. The mean values reported by the New FIAS are consistently lower than the mean values reported by the AFIS and Cottonscope. Similarly, the maturity distributions obtained by the New FIAS are positively skewed, whereas the distributions from the AFIS and Cottonscope skewed from positive to negative. The AFIS showed a narrower range of skewness values, whereas the New FIAS and Cottonscope showed a wider range of the…
