Interpretive Summary: In the current study, two extraction methods were compared in the extraction of wax from cotton. The Soxhlet method is a widely used method which successfully removes wax from cotton but has the disadvantages of requiring large amounts of solvent and sample and is time consuming. In contrast, the accelerated solvent extraction method or ASE allow for shorter analysis times, smaller solvent and sample requirements and is automated. The results show that the Soxhlet method is statistically different when two sets of cultivars were analyzed. It was also discovered that some damage to fiber follows both methods. Statistics reveal differences in the statistical significance of the varieties.

Technical Abstract: The cotton fiber wax extraction yields of the contemporary accelerated solvent extraction (ASE) method were compared to the reference Soxhlet extraction method. Two varieties grown in Lubbock, TX were examined, referred to as the STV5458 B2F and the FM9180B2F varieties. Effects of ASE extraction time and temperature were investigated. Characteristic environmental scanning electron microscopic (ESEM) images revealed fiber damage following both extraction methods, with the ASE method showing lesser damage. A one way ANOVA showed the two methods were found to be statistically different according to a 95% confidence level (p<0.05) when combining cotton varieties.
