Milan 2014: French design duo Ronan & Erwan Bouroullec will introduce their first fabric collection of upholstery textiles knitted from jersey in Milan next month (+ slideshow).

The Canal, Moraine and Gravel collections by Ronan and Erwan Bouroullec have been created for Danish textile brand Kvadrat.

"At the very beginning of our research there was a fascination for the structural traits of textiles that, observed under a magnifying glass, can be interpreted like a lattice of threads - building marvellous architectures," said the designers.

Each fabric is created using a double jersey knit, made from a front and a back layer that, when knitted together, show the elements of the internal structure on the surface.

The front layer is made from a mix of wool and polyester yarns that combine dark and light coloured fibres, while the back layer is made from polyester yarns in a single vivid colour.

"To reach this particular irregularity of wool colour, we chose to use a very soft dyeing treatment that resulted in a coloured surface made of diluted tones," said the designers. "Polyester, as a synthetic material, provides an intense plain colour accent."

The collection will be launched next month during the Salone Internazionale Del Mobile at Kvadrat's Milan showroom.

Here is some information from the designer:

Canal, Moraine, Gravel for KVADRAT

Three collections of 3D knitted and stretch upholstery fabric.

Constructed using a double jersey knit, the collections reveal new surfaces of slightly quilted fabric combining the stretch flexibility and firmness necessary to upholster a wide variety of shapes with the possibility of less points of stitching.

The knitted front layer of the textiles is made from fine melange wool and polyester yarns, which combines dark and light fibres. This ensures that they have a sensuous touch and feature a rich play of warm, delicate and irregular colour nuances.

The knitted back layer is made from unicoloured polyester yarns, in accent colours. These provide firmness and structure.
