In general, typical cross-section image analysis and microscopy reference methods for fiber maturity and fineness can be slow and tedious to perform. The Cottonscope rapidly, accurately, and precisely measures maturity (MR), fineness, and ribbon width simultaneously. The Fibrotest is a device developed by Textechno for measuring cotton length and strength properties. The Fibrotest provides more than 20 length and strength parameters and displays fibrogram, load-elongation curve, and fiber beard image. Lower Half Mean Length (LHML) algorithms (NFCA with Textechno) are being developed for the Fibrotest. Research will emphasize establishing the capabilities and potential of the Cottonscope and Fibrotest instruments for laboratory measurements of key cotton fiber properties on a wide variety of samples. Specific components of the plan of work include 1) obtain diverse fiber samples which represent a wide range of MR and fineness (for Cottonscope) and strength and length parameters (for Fibrotest); 2) perform comparative measurements to develop measurement protocols and determine the impacts of instrumental and operational variables on the results; 3) perform Cottonscope and Fibrotest measurements on the fiber samples to determine the relationships between the Cottonscope and Fibrotest results and corresponding fiber results from other methods; and 4) perform comparative analyses to determine the relationship(s) between the Cottonscope and Fibrotest results and yarn quality/performance (optional for years 2-3).
