The properties of the physical and mechanical fabric play an important role in the determination of the characteristics of the fabric and its function. These properties are only a reflection of structural specifications of the fabric from textile structure, threads, materials, and other processes. The composition of the double fabrics allows the construction of two layers either separate or connected with a variety of designs, and two different materials to each layer, which gives the resulting cloth many of the characteristics that may distinguish it from others, and make it suitable for cold or warm atmosphere or both together and at the same time achieve a sense of comfort in terms of appearance with meeting the goal of the use. The purpose of this research is to study the effect of felting a double fabric according to the appearance and properties of the resulting cloth, which was woven from cotton yarns to one of the two layers of fabric and wool of the other layer and with geometric designs of the two sides of the face and back. Laboratory test and statistical treatments showed a clear effect on the appearance of the fabric before and after the felting and significant differences of statistical significance for some of the physical properties of the double-layered fabric before and after felting and differences between equal and unequal designs after felting.
