AbstractHPLC columns packed with cellulosic textile materials as stationary phase were examined with respect to their chromatographic parameters. The interaction of the stationary phase with water‐soluble substances (mainly textile chemicals) was also studied. The size‐exclusion effects of the porous material were measured for molecules with MW 20−2 × 106, thus giving further information concerning structural changes during the pretreatment of textile materials. Electrostatic and sorptive interactions were detected simultaneously, but found to exert a minor influence. Using a recently developed mathematical model, the pore volume distribution of swollen celluose could be determined from the size‐exclusion data without the introduction of empirical factors. The applied HPLC method of characterizing cellulosic materials offers an alternative to the previously utilized static and chromatographic methods, especially for studies on pretreated textile m
