Variability of Individual Cotton Fiber Tensile Properties within and Between Samples

Tensile strength is the response of a fiber to an applied force. In spinning and weaving, various mechanical forces are exerted at high rates of speed, which may lead to fiber breakage. Therefore, inferior tensile properties lead to poor fiber length distribution, increased short fiber content, poor yarn quality, lower fabric appearance and low productivity. The primary goal of this research is to document the variability of single fiber tensile strength both within sample and between samples. The secondary goal is to elucidate the relationships between individual fiber tensile properties and other physical properties of cotton fibers such as bundle strength, length, fineness, and maturity.

HVI, AFIS, and FAVIMAT tests were performed on 104 cottons. Variability between and within samples were analyzed statistically and relationships between single fiber tensile strength and other physical properties have been established and explained.
