A friction-based textile finishing process that creates a smooth or napped surface on fabric.
From frot-, related to friction and rubbing (from Old French frotter, 'to rub'), plus the suffix -on; the term describes the mechanical action of rubbing fabrics to improve their surface.
Frotton is why some fabrics feel so incredibly soft and velvety—manufacturers discovered that controlled rubbing could transform how cloth felt without changing its actual fiber composition.
