Interpretive Summary: The overall aim of this article was to summarize the single fiber properties of samples consisting of cottons containing two genetically different parents and their progengy. The USDA Cotton Quality Research Station often collaborates with breeders to develop new varieties to unravel processing problems. Improved fiber quality is needed to make USDA cotton more competitive in the world market and improve U. S. textile mill efficiency.

Technical Abstract: The Favimat, a single fiber testing machine, it used to measure fibers from samples consisting of cottons containing two different parents FM832 AND MD51neOK) and their progeny. In order to get a representation of certain fibers within these samples, the cotton is further divided into the 17 and 19 Suter-Web array length groups.These fibers range in length from 1.00 to 1.125 in (length group 17) and 1.125 to 1.25 (length group 19). The Favimat measures the amount of force required to break up to 210 cN with a resolution of 1 x 10-4, while the fineness of these same fibers can be measured from 0.5 to 200 dtex. In a manner similar to the Mantis, tensile strength is determined using a constant rate of extension. A gauge length of 10 mm and cross-head speed of 20 mm/min under a pre-tension of 0.20 cN/tex were used in testing. Following single cotton fiber image capturing, fiber fineness is determined by the vibroscope method. The results suggest that the Favimat is satisfactory for measuring current and future cotton properties.
