Interpretive Summary: The presence of botanical trash remains an issue throughout the cotton industry. Botanical cotton trash such as leaf, stem, hull, bract, and others generates problems during ginning and textile processing. In the course of processing, the moisture content in cotton varies depending on the climate, storage, and addition of moisture for fiber performance. The fraction of trash that stays attached to cotton fibers are exposed to size reduction as well as different moisture contents. Efforts are currently being pursued to reduce and eventually eliminate this problem. FTIR has been utilized in identifying different botanical trash types by means of chemical characteristics. The effects on botanical cotton trash moisture content were studied to acquire a new approach of identifying the trash types.

Technical Abstract: In a previous study, Fourier transform infrared spectroscopy (FTIR) was utilized in identifying different types of botanical cotton trash as each was subjected to simulations of ginning and textile processing. Changes in the infrared spectra that occurred after heat treatment indicated that the need to further study the effects of moisture content in the different trash types on resultant FTIR spectra. This study will attempt to determine the effects on different trash types as the levels of moisture content are varied, therefore, providing a more in depth investigation in identifying the type of trash present in cotton fibers.
