Progress Report Objectives (from AD-416) Three levels of UHML and micronaire will be studied while attempting to maintain similar fiber strength and uniformity values. Ideally, cottons representing 1.00, .110, 1.20 UHML and 3.8, 4.4, 5.0 micronaire will be selected based on official USDA AMS classing data providing a range of length and micronaire. UHML and micronaire were chosen because they were shown to have the most significant relationship with AFIS short fiber content (SFC). Approach (from AD-416) A first generation AFIS will be retrofitted with current software. This particular generation of AFIS was chosen because it is an excess item at our Unit and it has less measurement modules and automation to interfere with this effort than the newer generation. The dependent variables of this research project will be HVI Upper Half Mean Length (UHML) and micronaire. The independent variables will be: environmental conditions, roller speed, transfer ratio, combing action, and roller cover. Standardized temperature and relative humidity conditions will provide the baseline of fiber conditioning and AFIS testing. Significant Activities that Support Special Target Populations This report documents research conducted under a reimbursable agreement between ARS and Cotton Incorporated. Additional details of research can be found in the report for the in-house associated project 6655-41440-033- 00D. This first year project made progress in developing an outline for future studies to continue based on equipment that was designed, customized, and modified this year. Hopefully, the ability of the AFIS� to better measure fibers could provide the textile industry a rapid and more reliable instrument as well as a standard which is as important for breeding and textile research as it is for the marketing and utilization of cotton.� In review, this project repaired, cleaned-up, and ran a first generation AFIS� (non-operational unit) that was retrofitted with current software.� Fiber property measurements were performed at our laboratory on mixed and blended fibers extracted from bales.� The three bales each for fineness and length were always statistically different from each other.� Future studies will require additional fiber testing performed using these techniques.� Servo motors and controllers were installed and controlled using a control station in order to control the fiber individualizer and beater speeds. Monitored through conference calls, emails and visits at professional meetings.
