Fabric Switch: Sourcing Sustainable Silk

A guide for designers looking to explore innovative silk fibre alternatives and find fabric suppliers producing organic and peace silk.

Intro

Prized for its drape, softness and breathability, silk is a staple fibre in the production of luxury garments. It currently only makes up a small proportion of global fibre use, at 0.2%, but has a high unit price of US$15 per kilo. 

In a process largely unchanged for centuries, silk is reeled from the cocoons of silkworms and then spun into fine yarn. Social, environmental, and animal welfare concerns around the production of silk have led to innovations in more sustainable alternatives in recent years.

Animal and environmental impact

  • 600 billion silkworms are killed each year to produce silk fibre
  • Cultivation of mulberry leaves to feed silkworms requires less pesticide and water use than cotton, however the fibre to fabric production of silk is ranked ‘high’ by the Higg Index, mainly due to to high energy use

Impact on people

  • Uncertainty around the value that is shared amongst those who farm the silkworms or process the thread
  • Health issues for farmers and silk ‘reelers’ (who unreel the cocoons using boiling water) 
  • Reports of bonded child labour in silk production in India and child labour reported in Uzbekistan

Silk Alternatives

Flower Power: Lotus Silk 

Made from the fibres in the stem of the lotus flower, this fabric is labour intensive to produce but has many of the desirable qualities inherent in silk - it is naturally soft, lightweight, breathable, and almost wrinkle free. 

Samatoa Lotus Textiles in Cambodia have revived this fabric and employ at-risk woman to provide steady income in a safe and positive environment. The mill is run as a Cambodian social business, with Fair Trade principles underpinning their operations.

Ahimsa ‘Peace’ Silk

Based on the concept of non-violence, Ahimsa or Peace silk is made from silkworms, but they are left to complete their full lifecycle, emerging from the cocoons before they are processed. 

The emerging moths break the silk thread, creating a shorter length and a different handfeel of the finished textile, but ensures that the animals are not harmed in the production process.

Animal rights group, PETA, do however still warn of poor social and animal rights practices in the production of peace silk.
