What are cellulosic fibres (part two): Man-made

Stephanie Steele Friday, 1 May 2020

Now that you understand what a cellulosic fibre is, along with the feedstock sources of natural cellulosic fibres, we'll now dive in to what the man-made, or regenerated, cellulosic fibres are.

There are arguably more environmental issues involved in the production of man-made cellulosics, due to chemical input and strain on ancient forests, while natural cellulosics would arguably be more framed by ethical considerations due to the impact on smallholder farmers and traditional craft textiles. This lesson explores certain issues surrounding man-made cellulosic fibres, along with some innovations in play to improve this hefty textile market.

All of the takeaways can be found in the handy downloadable guide below.


In this video you'll learn:

  • A rundown of all of the man-made cellulosic fibres, including:
  • Rayon ~ cupro and viscose methods
  • Acetate and triacetate
  • Bamboo viscose and bamboo linen
  • Regenerated cellulosics Lyocell and Modal
  • Recycled cotton
  • The importance of forest and chemical management when producing man-made cellulosics
  • Classifying fibres with Made-By's Environmental Benchmark

  • Creating new sustainable cellulosic fibres from discarded clothing

    Summary

    One of the key sustainability issues around the use of wood pulp for the production of fabrics like viscose and lyocell is the destruction of forests that are impossible to replace. But what if there was a waste material that we have a vast quantity of already that could replace wood pulp in the cellulosic fibre process?

    We are thrilled to present the Circulose arm of the Swedish re:newcell project that takes discarded clothing and turns it into a brand new cellulosic fibre. In this lesson, you'll learn more about the material, the science behind the process and why it is sustainable.
