Polyester 

The polyester fibre is a versatile synthetic fibre that is easy to care for. But it also uses large amounts of energy to produce, is based on non-renewable petroleum and it is non-biodegradable. Whilst we see a role for polyester as a key fibre in the near term, these characteristics mean that we need to increase our sourcing of preferred materials and reduce virgin materials, as well as investigate alternative fibres for long-term viability.
