The origins :

The cloth used by the forerunners was the "burat de Nîmes", a fabric made from cotton waste in Nîmes as well as in northern Italy and especially in Genova. The name jeans is a contracted version of the word "genovese" meaning "Genoese", the name used for the trousers worn by Genoese sailors. Later, the indigo-coloured "serge de Nîmes" (the origin of the name denim) was imported. In the 19th century, jeans made of cotton twill with warp and weft threads of the same colour were generally used as work clothes. Denim (made of twill with blue warp threads and ecru weft threads) was particularly appreciated by mechanics for its highly resistant qualities

The technical part:

Denim is a tangle of indigo and ecru threads. On a loom, the indigo threads will be the warp threads (vertical) and the unbleached cotton threads the warp. Everything then is a story of weaving… looking at the inside of jeans, it is even more visible: 

- oblique linear weaving (authentic, right hand / left hand twill) 

- alternating weaving right / left (broken twill) which maintains the cut of the canvas 

The edge of each of the rolls of woven jeans is covered with a thread of contrasting color (historically red). It is this same edge that some purists look for on their selvedge jeans.

CUBjeans fabrics:

All of our trousers are cut from high-end materials. The denims and fabrics used by the CUBjeans brand have been selected for their quality, modernity, appearance, color and comfort (2% stretch which provides optimal fit while having the look of 100% jeans cotton).

CUBjeans colors and washes:

If the weaving of CUB jeans remains of the twill type, the colors of threads used can be different and bring a completely different physiognomy to the jeans. Likewise, CUB stylists can intervene on fabrics by subjecting them to:

an over-dyeing (the whole of the jeans is immersed in a bath of color)
an internal scraping (only the reverse of the jeans will have the chosen color),
application of a resin on the outside of the jeans (slightly shiny layer which will fade over time, but which protects the color of the jeans while giving it a more dressy look)
