We get asked a lot- are your dyes natural? Are your fabrics sustainable?
What is natural?
Is Natural... vegetable dye?
We have tried vegetable dye but have not found them good for large scale use. It runs and does not wash well. To get a good fix with vegetable dyes you need chemical mordants that are really environmentally unfriendly and dangerous. Also, vast amounts of vegetable matter are required and that causes pollution and also is that a good use of land?
For local use - for having fun with onion skins and beetroot- great. For large scale, we don't think so.
We use low impact chemical dyes and our mill fabrics are GOTS certified which covers the safety for workers and end users .
Genesh supervises our dyeing in Kerala. Have a look here for his description of the process.
In Kerala we use Novacron dyes which are made to pass Oeko-Tex standards - ie they are safe.
Fabric that is made in a GOTS certified mill will be covered by GOTS certification including the dyes used.
