As long as human beings exist, they have to produce and consume. Technological developments, population growth and the subsequent globalization revealed many problems. These emerging problems affect the lives of living things negatively and become the starting point in a global crisis. It becomes definite that precautions should be taken in this direction and that we should take the concept of sustainability to our center and act for a more livable world for the next generations.

 As in all sectors, sustainability is becoming a very important concept in the textile and ready-to-wear sector. In recent years, it has become very important for humanity to reduce the wastefulness of the use of natural resources and to ensure their effective use and to establish a sustainable balance in terms of economy and social aspects.
