              not easy to translate the performance obtained on a laboratory scale to the
              performance on an industrial scale. This is because the deformation factor
              α is different in different systems. The best way would be to set up labora-
              tory-scale experiments in such a way that they have an α-factor which is
              the same as its value on full-scale equipment. To prevent the phenomenon
              of enzyme exhaustion in the pores of the fabric, it is possible to enhance
              the enzyme concentration in the enzyme padding system. However, this will
              be very costly and therefore not a realistic option. The current installed base
              in textile treatment companies are based on traditional chemistry. It has
              been shown here that enzymes require another approach and, thus, it is
              expected that a breakthrough in the application of enzymes will only occur
              if machine manufacturers develop special systems in which the squeezing
              factor is as high as possible. Incorporation of ultrasound in such new systems
              could lead to the desired performance.
