Ecojilin is a viscose fibre made using pre-consumer cotton linters, a by-product of cotton processing. Developed by Jilin Chemical Fiber, it uses recovered cellulose as the raw material for regenerated viscose fibre. Ecojilin is recognised for incorporating recycled cotton-derived material into the production of viscose.

Twill is a woven construction characterised by visible diagonal lines across the surface. The structure can range from fine and subtle to heavy and pronounced, depending on the yarns and weave. Denim, gabardine and drill are all examples of fabrics made with twill constructions, but their weight, surface and intended use differ considerably.

Founded in Britain in 1970, Jigsaw combines contemporary design with an emphasis on craftsmanship and quality fabrics. The brand works with its own atelier and produces many collections in limited runs, with a focus on distinctive pieces rather than high-volume fashion. Jigsaw also has a longstanding connection with British arts and culture through its Art Foundation.
