Developments of new and varied polymers which are processed either purely or in blends, can lead to new and improved fibers in the spin process. The adaptation of the characteristics of these fibers to the needs of the follow-up processes requires sophisticated development work being affected by many influencing factors.
The investments in appropriate spinning lines for the development work are high and the decision makers will face a dilemma. As it is not yet known how the future process must be designed, the plant to be established may only contain as little as possible process determining elements, which cannot be varied.
The system for researchers must remain very flexibly adjustable. That means to arrange and keep the processing steps in the sequence of the yarn treatment variable and flexible. It is necessary to be able to customize the control of each test assembly without programming effort.
Thus the following questions have to be answered: which aspects need to be considered by mechanical engineers during the development work of a researcher of a new filament in order to give the developer of the yarn technology the highest possible flexibility; and how must the tools be constructed to be able to repeatedly take into account new ideas for the design of the spinning line?
The paper presented during the lecture attempts to answer such issues on the basis of examples.
