Interpretive Summary: Throughout the development of cotton fibers, they undergo changes in their crystalline structure. This study employed X-ray diffraction (XRD) and Fourier Transform Infrared (FT-IR) Spectroscopy data to measure the crystallinity of cotton fibers at various developmental stages. The segal method was used for XRD data analysis, while the FT-IR data were processed using the three-band ratio algorithm. The findings indicate the importance of the chosen measurement technique because the less change in crystallinity was observed when using the segal method than the three-band ratio algorithm.

Technical Abstract: Cotton fibers develop a crystalline structure during their developmental stages. This study assessed the crystallinity of developing cotton fibers using X-ray diffraction (XRD) and Fourier Transform Infrared (FT-IR) Spectroscopy data. Two commercially available cotton fiber varieties at various developmental stages ranging from 21 to 60 days post-anthesis (DPA) were selected. The segal method was applied to analyze the XRD data, while the three-band ratio algorithm was utilized for the FT-IR data. The results showed that the influence of DPA on crystallinity was less pronounced with the segal method compared to the three-band ratio algorithm, indicating the significance of the measurement technique employed.
