The demand by the end consumer for garments with functionality and comfort are basic
requirements for success. And right in keeping with this line of thought is the adaptive membrane system c_change™, which Schoeller Switzerland has been using recently and, which offers distinctive benefits for a variety of different markets. The “smart aspect” of
c_change™ is the flexible adaptation of the water vapour permeability. The c_change™ membrane also offers a high level of water and wind proofing and, due to the

| adaptive system, moisture vapors can escape. Fir cones offer one of the best-known examples of a flexible response to moisture and adaptation to temperature change. When the weather is cold or wet they close up. When it gets warmer and drier they open up again. The membrane technology used by Schoeller works in a similar way which is why, when necessary, the Schoeller innovations with c_change™-membrane adapt to the activity of the wearer and the changing climatic conditions. In typical trade jargon, this type of membrane is known as a “shape memory material”.
