The present invention discloses a short-process fully recycled foam material spinning process within the field of fiber preparation technology. It addresses the issues of multiple steps, poor fabric performance, and suboptimal dyeing results in existing techniques. The process involves adding polyester pellets, colored foam material, and color masterbatch into a mixing chamber. After blending and stirring, the mixture is conveyed to a twin-screw extruder, where it undergoes vacuum melting. extruding filaments, wrapping spandex fibers via a magnetohydrodynamic device, assembling mixed filaments into roving to form primary fibers, followed by drawing and crimping processes to achieve short-process fully recycled spinning. This invention replaces single-screw spinning with a twin-screw extruder, eliminating the drum process in traditional spinning. This significantly shortens the production flow, stably intertwines fibers of different deniers (polyester and spandex), and utilizes spandex's überlegene Elastizität, um einen dreidimensionalen Kräuseleffekt im Polyester zu erzeugen, was die Gewebeparameter verbessert. Es mischt auch Schaumstoffmaterial und Farbmasterbatch gleichmäßig, sodass eine gleichmäßige Verteilung des Masterbatches in den gemischten Fasern die Färbeeffizienz verbessert.
