Once the initial feasibility studies researching simple spinning testers have been completed, the next steps in fibre development require a spinning machine for experimental purposes. Rheological data from many different systems of solvents and polymers, the corrosive properties of the components and all other key parameters (such as pressure and temperature) must be determined. This information can then serve as a basis for the layout and design of the system. Depending on the number of spinning points chosen, the scalability of an experimental system must be taken into consideration to the broadest extent possible. Specifically, calculations for the heat transition, flow rates and pressure losses must be made to ensure the correct nozzle geometry. Simulations must also be conducted to test the results of such calculations.

Another factor is the production of sufficient material to ensure that the sampling results are correct, especially when determining the system’s capacity.

The meticulously selection of the various measuring points will be compared against the automation design, so ensure that they form a stable foundation for the collection of the necessary parameters.

The pilot systems that we install will be constructed as modules. Using modular systems ensures the maximum flexibility for testing the various components and collection of all of the parameters for the entire mechanical process.
