Fabric composition may not be the first thing you consider when selecting a new textile, however, with a wide range of options available you may be interested in finding out more about what a fabric is made of. We break down the options on our online sample ordering service as: wool, synthetic, coated polyester, Trevira CS, vinyl, other (e.g. leather), and environmental (to include bast fibre fabrics and EU Ecolabel certified products). Here we cover some basic facts on wool, polyester, bast fibres and closed loop yarns.
