Eri Silk (red) Roving/Sliver (A1 Grade) Wild Silk - 200g

Price: $90.00

Most forms of eri silk are white; however, Philosamia ricini silkworms raised in the Goalpara District of Assam, India (and a few other locations) are brick red.

Eri silk has less sericin (the protein ‘glue’ that protects the silk and holds the silk together in its cocoon shape) than other types of silk, so the eri cocoon has a fuzzy texture. Click here to see the cocoons

The natural red color is ‘fugitive,’ meaning the color will fade when exposed to the soaps and other ingredients used during degumming.  Typically, the red color reverts to cream or beige during degumming. 

However, our red eri roving was processed differently—just 40-50% of the sericin was removed during degumming.  This reduces exposure to degumming ingredients, enabling the silk to retain its brick red color.

We have wetted the red eri silk roving in hot tap water for 24 hours and the red color is retained--it did not stain Bombyx/mulberry or natural (unbleached) Tussah silks in the same basin. 

We repeated the experiement adding a touch of mild soap (e.g. original blue "Simple Dawn®") and the red color still stayed in tact, even when sharing the bath with white eri silk and natural tussah silk.

However, sharing a the bath with bleached tussah or different soaps could affect the fugitive nature of the red color, so testing is highly recommended.

Our eri wild silk top has a 3.5 to 4 inch fiber length and is heavenly to touch. 13.5 to 17 microns

Treenway Silks has used the same silk supplier in Inda for over 15 years and he consistently delivers top quality.

PEACE SILK? not really.
Silk
is an eco-friendly product.  

If you have past issues of SpinOff magazine, you might want to read Winter 2013, page 42, which has a terrific article by Karen Selk, founder of Treenway Silks.  She "myth-busts" many things related to "peace silk".  Here's the article's sidebar info:
  • Ahimsa silk is a patented term referring to an eco-friendly method of manufacturing spun mulberry silk
  • Eri silk could be peace silk, but most likely it is not, as almost always the pupa is removed for feeding people or other animals
  • Don't assume that because tussah, muga and eri silk are wild silks they are peace silks--muga and tussah are also reeled and the eri pupae are used for food--so check your sources.
  • The only true peace silk is made from cocoons in which the pupa has matured into a moth.  Most often this is for breeding purposes, and the quantity of this type of silk is very small.
  • The caterpillars produced from the eggs resulting from all the matings from unstilfed cocoons (200 to 500 eggs per moth) would not have enough food and they would die from starvation and neglect.
  • Sericulture is a sustainable, renewable, environmentally friendly resource that gives million of rural people a healthy, family-oriented lifestyle.
Treenway Silks views the entire silk eco-system and what that means (see the last bullet above), so we choose not to seek out and carry "peace silk", the origins which seldom can be substantiated.
