Ahimsa silk

Ahimsa silk, also known as peace silk, is a type of silk that is purported to be made in a fashion that is much more humane to the creatures creating the silk than many traditional methodologies. Ahimsa is a word that derives from the Sanskrit language and translates as non-violence. This ideal is a key component of a larger way of living that is taken up by many people in the Indian subcontinent, most famously Mahatma Gandhi. A vast majority of Ahimsa silk is made from the cocoon of the Bombyx mori moth whose young feed on the leaves of the mulberry tree.

Kusuma Rajaiah, a government officer from India's Andhra Pradesh state, applied the theories behind the Ahimsa way of life to the making of silk and found that it was possible to create silk without killing the creatures that created it. Traditional silk manufacturing methods involve boiling the cocoons of the silkworm and then sorting out the threads to be used later in production. Rajaiah's idea involves a gentler method, specifically letting the worms hatch and then using the cocoons once vacant. He started deploying this process in the year 1992 and has hence been supported by a larger community of people interested in the welfare and rights of animals and non-humans.

The process of creating Ahimsa silk begins in one of two ways: either the pupa is allowed to hatch and the leftover cocoon is then used to create silk, or the cocoon may be cut open, achieving much the same result but often saving the resultant material from contamination by urine from the hatching moth.

While Bombyx mori are the preferred species for creating Ahimsa silk, there are a few other types of species that fall under the category of Ahimsa silk, which is defined not necessarily by the species of the moth involved but by the methods for harvesting the cocoon of that species. The other types of silkworm that are used for this process are a subspecies of the Ailanthus silkmoth and several types of Tussah or Tasar moths: the Chinese tussah moth, the Indian tasar moth, and the muga moth.

The subspecies of the Ailanthus silkmoth, Samia cynthia ricini, eats the leaves of the castor bean or cassava leaves. It is also known as the Eri silkmoth. Eri silk is made from the cocoons of these particular insects and is also produced using less violent methods than the normal heat treating, but the quality of Eri silk is often seen as inferior to that of the silk created by the offspring of the Bombyx mori moth.
