The Effects of Air Pollution on Exposed Cotton Fabrics

Effect of different fabrics types on the adsorption of air pollution in residential and industrial atmosphere in Cairo-Egypt

“…Therefore, air pollution is one of the most reason for degradation cellulosic fabrics. It known before that, exposed natural yarn affected by losing in tensile strength in winter more than in summer which ascribed to one or all of the triple increment in coal utilization, together with a high incidence of quiet, foggy days that brought about a higher acidity (sulfuric) in the winter [10,11]. Natural fabrics consist mainly of the cellulosic materials (cotton, viscose and viscose rayon) and fibers as silk, wool, flax, hemp and jute [12].…”

Nitric acid concentrations in southern California museums

“…Prolonged exposure to atmospheres containing oxides of nitrogen is known to cause deterioration of materials including dyes, textile fibers, plastics, rubber, and metals (2). For example, exposure studies have found fading and yellowing of a variety of textile dyes (3)(4)(5), degradation accompanied by loss of tensile strength of cotton and some man-made fibers (6)(7), and surface corrosion of metals (8)(9)(10)(11)(12)(13).…”

“…A class of problems for which a model is available is the sorption of nonionic hydrophobic organic chemicals to soils and sediments [see Karickhoff (6) for an excellent review]. The characteristic that indexes the hydrophobicity of the chemical is the octanol-water partition coefficient, Kow.…”

“…First, data from diverse sources are evaluated for the presence of a minimum number of necessary parameters. The model is patterned after the model for nonionic hydrophobic organic chemicals (6,8). The critical micelle concentration (CMC) of the surfactant is the analogue of Kow in the models for nonionic hydrophobic organic…”
