Selvedge (UK) or selvage (US) refers to the narrow and tightly woven, self-finished edges that are the natural endings on fabric that’s been woven on an old school shuttle loom. In denim the selvedge is usually white and has a coloured thread in the middle, which was originally added to help manufacturers recognise the different qualities that they were producing for various clients. Although red thread has become synonymous with selvedge fabric, DENHAM styles often feature special selvedge weaves in other colours. Selvedge fabrics are woven on narrow 28-30” shuttle looms. In the 1970s and ‘80s these were replaced by more effective and wider 58-60” projectile looms. Although the older narrow looms produce denim fabrics at a slower rate, their shuttle technology also produces more natural irregularities across the denim’s surface. These irregularities come to life when subjected to special wash-and-wear-pattern recipes, and can produce more beautiful finishing effects.
