Abstract

This is a progress report on a comparative analysis of the fineness/maturity measurement in the latest generation AFIS machine at the International Textile Center. Comparisons are made with other measurements that also capture information related to fineness and maturity. These are the following: HVI micronaqire; FMT micronaire; FMT maturity ratio; FMT fineness; AFIS Diameter (from older generation AFIS). Comparisons are also extended to the predictive of fineness and maturity measurements on the levels of fiber bundle strength and yarn strength. This is done for yarns spun both on the ring spinning system and on the open-end rotor spinning system. Comparisons among the fiber measurements come from a sample of 191 Upland and extra long staple (ELS) cottons from over the world. For analysis related to the spun yarns, the results were taken from a subset of 66 cottons, with all of these being Upland type cotton. The limited number is only because spinning are not completed; these tests are even now in the process of being done. These results suggest that more attention should be focused on the meaning and measurement of standard fineness. We are hopeful that our new AFIS will provide a platform for brining this measurement of the forefront. Conceptually, such a measurement already embodies both the fineness and the maturity dimensions, both of which are known to be fundamental indicators of the use-value of cotton fibers in textile manufacturing.
