A review of research reported in the literature on the sorption of SO2 onto textiles and related materials is presented. The detrimental effects of pollutants on the me chanical and aesthetic properties of textiles have been well documented and are also briefly noted; however, there is a consistent lack of data on the rate and extent of sorption of air pollutants onto textiles. Sorption rates, expressed as deposition ve locities (

g), are affected by the environmental chamber used for exposure. There are differences in sorption that may be attributed to fiber type and also to the geometry of the textile structure (i.e., fiber, yarn, fabric) on exposure. These factors, however, have not been systematically assessed and although the process of sorption by polymer films has been examined, the corresponding mechanisms of sorption/desorption phe nomena for textile structures have not been elucidated. The literature reviewed also shows that most studies of fibers have been primarily concerned with the sorption behavior of wool.
