The relationship between instrumental leaf grade and Shirley Analyzer trash content in cotton lint

Abstract: With the increasing acceptance of high volume instrument (HVI™) instrumental leaf grade index in both domestic and international trading, there is a continued interest in the relationship between instrumental leaf grade and equivalent trash gravimetric content (% percent by mass) from cotton customers and regulators. Due to the complexity of not only trash type, size, and its weight distribution but also the nature of HVI and gravimetric methods, it is an on-going challenge to examine such a relationship.

“…However, this trend is difficult to interpret because the harvest history or production region of each of these fiber samples is unknown. The pattern in Figure 5 is similar to a previous report (Liu and Delhom, 2018), in which the first principal component (PC1) scores from principal component analysis (PCA) of near infrared (NIR) spectra of SA visible trash remains representing six leaf grade samples were related to leaf grade.…”

“…Table 1 summarizes the range, mean, and standard deviation (STDEV) of SA total trash content (%) for six instrumental leaf grade cottons, in which 30 and 15 samples were selected randomly from a set of 50 cotton lint samples and tested by Shirley Analyzer in 2016 (Liu and Delhom, 2018) and 2017, respectively. Like SA total trash content increased from 3.41 to 6.64 % in 2016 (Liu and Delhom, 2018), SA total trash content increased from 4.68 to 8.20 % with instrumental leaf grade in 2017. Notably, SA total trash of 15 samples in 2017 measurement is about 1.2 ~ 2.4 % higher than that of 30 samples in the 2016 test.…”
