Abstract
The article opens with a discussion of the factors which influence the soiling of textile materials by airborne dirt and of a method for measuring and expressing the extent of soiling of textile materials. An account is then given, with experimental data, of the soiling of textile fabrics by exposure to moving air, by thermal precipitation and by electrostatic attraction of airborne particles, and of the effect of fabric wettability on the appearance of a cotton fabric soiled by exposure to a damp polluted atmosphere. Finally, the article introduces the "murk" unit of air dirtiness and deals briefly with the measurement of atmospheric murk values. Typical data for a residential district are given showing differences in the magnitude and diurnal variation of air dirtiness in summer and autumn.Keywords
