Rayon definition clarifies regenerated fibre production, spinneret extrusion, and filament versus staple commercial forms.

Rayon is a man-made textile fibre produced by chemically converting plant cellulose into a liquid solution that is extruded through spinnerets (spinning) to form filaments, which are then hardened by drying or chemical means. Filaments may be cut into staple and twisted into yarn. Early commercial nitrocellulose fibres were discontinued for safety. The entry emphasizes rayon as a regenerated fibre derived from softwoods or cotton linters and outlines key manufacturing steps and commercial fibre forms.
