Dyeing:
Many textile manufacturers use dyes that release aromatic amines (e.g., benzidine,
toluidine). Dyebath effluents may contain heavy metals, ammonia, alkalai salts, toxic
solids and large amounts of pigments - many of which are toxic. About 40 percent of
globally used colorants contain organically bound chlorine, a known carcinogen.
Natural dyes are rarely low-impact, depending on the specific dye and mordant used.
Mordants (the substance used to "fix" the color onto the fabric) such as chromium are
very toxic and high impact.

Well with the help & encouragement from other sources! I have carried out several experiments.
The most natural approach I have tried is 100% organic but, unfortunately only produces a dark grey colour rather than black.

I think the why bother attitude is a bad one. the human race would get no were if the attitude was always "lets just go down the shop and buy it". I'm not sure if there is anything safe out there, but i definitely think its worth a look and quite interesting. Could opens up possibility for skint scapers if you find some thing. I'm looking foreword to good luck mate.
