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.
