By integrating a miniaturized melt spinning device with an advanced synchrotron beamline, in-situ experiments can be conducted to observe real-time process control and microstructural evolution during melt spinning, opening up a new frontier in high-performance fiber development.

During melt spinning, polymer chains dynamically align and crystallize during cooling and drawing, thereby determining the final performance of the fiber. Instead, much of the related understanding has come from empirical knowledge, simulations, and limited experimental data. By combining TPS 25A1 microbeam X-ray scattering with a miniature melt-spinning device, we achieve in situ, real-time monitoring of microstructural evolution, offering new insights for process optimization and manufacturing of high-performance fiber materials.

Taiwan’s synthetic fiber industry is primarily based on melt spinning technology. This technology offers a miniaturized in-situ melt spinning research platform that combines real-time process control with microstructure tracking, effectively reducing R&D costs, shortening development cycles, and significantly boosting innovation efficiency in the industry.
