Abstract
The surface areas of dyed and undyed secondary cellulose acetate fibers have been determined using low-temperature nitrogen gas adsorption by the method of Brunauer, Emmett, and Teller. The results confirmed earlier work using p-nitrophenol, in which it was shown that there is a marked change of surface area of dyed fiber in the region corresponding to a theoretical monolayer adsorption of the dye.
