Modal® is a type of Rayon™, a semi-synthetic fibre made by spinning reconstituted cellulose often from natural plant extract. Modal® is used alone or with other fibres such as cotton or Spandex™ in items such as pyjamas, towels, bathrobes, underwear and bed sheets.
Modal® underwear is also often blended with a stretch fibre as well as cotton but it stays breathable. Unlike garments made from pure synthetic fibres like Nylon™ and Polyester™, Modal® underwear does not trap perspiration and odours.
Rayon®, Modal® and Lyocell™ are all produced from renewable plants such as beech trees, pine trees and bamboo. All three fibres are biodegradable.
