Direct, Non-Destructive, and Rapid Evaluation of Developmental Cotton Fibers By ATR-FTIR Spectroscopy

Chemical, compositional, and structural differences within the fibers at different growth stages, as well as their physical properties and end-use qualities, have been investigated considerably through a number of well-defined protocols. Such knowledge is of value to cotton breeders and growers for cotton enhancement and to textile processors for quality control. Due to its direct, non-destructive, and rapid attribute, this study reports the utilization of attenuated total reflection Fourier transform Infrared (ATR-FTIR) spectroscopy method to acquire compositional and structural information of fibers as young as 10 DPA by the strategy of simple algorithmic analysis, and then to compare the secondary cell wall synthesis of fibers at various developing periods.
