cotton, rayon and linen), protein fabrics, which come from animals (e.g. The classification of textile industries depends on the type of fabrics they produce, including cellulosic materials obtained from plants (e.g. However, one of the problems associated with textile factories is the unacceptable effluent, especially dyes, which are difficult to degrade. China is the most important exporter of all types of textiles, followed by the European Union, India and then the USA (Ghaly et al. Textile industries positively affect the economic development worldwide. The processes carried out during textile manufacturing and the chemicals corresponding to each process are also discussed. These ingredients are also evaluated based on the typical characteristics of textile wastewater, and special constituents to simulate these characteristics are recommended. This review collects the scattered information relating to artificial textile wastewater constituents and organises it to help researchers who are required to prepare synthetic wastewater. This paper presents a critical review of the currently available literature regarding typical and real characteristics of the textile effluents, and also constituents including chemicals used for preparing simulated textile wastewater containing dye, as well as the treatments applied for treating the prepared effluents. The treatment efficiency of any pilot-scale study can be examined by feeding the system either with real textile effluents or with artificial wastewater having characteristics, which match typical textile factory discharges. Therefore, environmental legislation commonly obligates textile factories to treat these effluents before discharge into the receiving watercourses. Textile wastewater contains dyes mixed with various contaminants at a variety of ranges. Textile industries are responsible for one of the major environmental pollution problems in the world, because they release undesirable dye effluents.
