The physical properties of six ICCS fibers—B—26, C-36, D-5, E-4, G-17, and I-26-their percent crystallinity, and the amount of absorbed water are measured in order to establish relationships with specific surface areas measured by the absorption of methy lene blue in a liquid phase. The results show the relationships between the surface area as measured by methylene blue absorption and fineness as measured by the gravimetric method, FMT3, and AFIS. Furthermore, there is a linear relationship between the surface area and the water content of cotton fibers, as determined by thermal-balance analysis. There is no clear relationship between the surface area and the percent crystallinity of the fibers.
