​Kelly defines fiber maturity as the relative thickening of the secondary cell wall. Immature fibers can cause problems during processing and can degrade degree yarn and fabric quality. Kelly discusses two approaches to measuring fiber maturity and fineness: micronaire, which is an airflow test, and the advanced fiber information system (AFIS), which uses electro-optical sensors. He closes the presentation by discussing current research on these topics.

About the Presenter

Brendan KellyBrendan Kelly runs the Cotton Phenomics Laboratory at the Fiber and Biopolymer Research Institute in Texas Tech's Department of Plant and Soil Science. He holds a joint appointment with Texas A&M AgriLife Research. His research utilizes large cotton fiber phenomics data sets generated by modern cotton fiber quality evaluation instruments. One of his primary goals here at Tech is to work with the research community and industry partners to improve the utilization and understanding of cotton fiber quality in research. His approach includes leveraging information about fiber quality provided by existing instruments, along with the evaluation of new protocols and instruments. Dr. Kelly's multivariate approach has led to a better understanding of the impact within-sample variation in fiber quality has on industrial processing and spun yarn quality. Dr. Kelly is a West Texas native from Midland, TX. Prior to joining the Texas Tech faculty, Dr. Kelly worked as a research associate and research assistant at Tech's Fiber and Biopolymer Research Institute. He also served as a research assistant and teaching assistant in Tech's Department of Plant and Soil Science. He received his bachelor's degree in mathematics and his doctorate degree in Plant and Soil Science from Texas Tech University.​
