Title: Innovations by Hansjörg Meise in Multifilament Thread Production
Introduction
Hansjörg Meise is a notable inventor based in Leichlingen, Germany. He has made significant contributions to the field of textile engineering, particularly in the production of multifilament threads. With a total of 2 patents to his name, Meise's work focuses on enhancing the efficiency and quality of thread manufacturing processes.
Latest Patents
Meise's latest patents include a method and device for producing a multifilament thread from a polyamide melt. This innovative technique involves cooling freshly extruded filaments and combining them to form a thread. The process is designed to achieve low boil-off shrinkage while maintaining high strength. The thread is taken off at a take-off rate between 3600 m/min and 4600 m/min, preferably from 4000 m/min to 4400 m/min, using a first godet group with unheated guide casings. Afterward, the thread undergoes full drawing between the first and a second godet group with heated guide casings. The thread is then heated to a temperature range of 140°C to 200°C under tension and relaxed before passing through a contact-free cooling section.
Another significant patent involves a method for melt spinning, stretching, and winding a multifilament thread to form an FDY-yarn. This method includes extruding a plurality of filaments from a thermoplastic melt, cooling them, and gathering them into a filament bundle without the addition of a preparation fluid. The filament bundle is drawn off at speeds exceeding 1,500 m/min, heated above the glass transition temperature, and stretched at drawing speeds above 4,000 m/min. The device designed for this method includes a preparation device positioned between the drawing and winding devices, ensuring efficient production.
