Title: Hung Manh Nguyen and an Apparatus for Spinning Hollow Bicomponent Filaments.
Introduction
Hung Manh Nguyen is an inventor associated with Charlotte, North Carolina, and Arteva North America S.a.r.l. His patent describes equipment for producing hollow bicomponent filaments that can self-crimp into a spiral configuration.
Latest Patents
Nguyen is associated with 1 patent: “Apparatus for Spinning Hollow Bicomponent Filaments.” The invention uses a distributor, a spinneret, and a shim positioned between them to guide two polymers with different melt-viscosity properties through separate portions of the spinneret holes. The polymers exit through asymmetric C-shaped apertures designed to prevent hydraulic splitting and reduce the risk of filament kneeing. They then join to form hollow filaments, which are quenched and self-crimp because of the polymers’ differing properties.
Career Highlights
The available information connects Nguyen’s patent work with Arteva North America S.a.r.l. The invention focuses on spinneret design and polymer flow control for manufacturing hollow, self-crimping filaments.
Collaborations
James Richard Goodall is identified as Nguyen’s coworker. The supplied information does not specify his role in the patent or the invention.
Conclusion
Hung Manh Nguyen’s patent presents a specialized approach to producing hollow bicomponent filaments by controlling polymer flow through a carefully designed spinneret and shim.
