This strong cotton fabric was first produced in the city of Nimes in France which is where it gets its name – denim.
After the cotton fibres have been spun into yarn, they are dyed and then woven using a twill weave which creates a subtle diagonal ribbing effect. This is done using either a shuttle loom to produce selvedge denim or a projectile loom which creates a more delicate edge that will need to be sewn to prevent fraying.
Although denim is most commonly associated with indigo-coloured jeans, it can be dyed in a variety of colours and can be used to make many other garments such as jackets and skirts, as well as other products including bags and upholstery.
The sustainability of denim comes from its durability which enables denim products to be reused many times.
