Frequently Asked Questions
What fabrics can be dyed with Blackest Black?
Blackest Black is suitable for dyeing natural fibres: cotton (including denim/jeans), linen, and rayon (viscose). Wool, silk and synthetic fibres, like nylon and polyester, won't work. Note that natural fibre clothes may have stitching made of synthetic materials.
Is it safe?
Blackest Black is a reactive dye, also known as cold water dye. The water only needs to be about 40°C (105°F), so it's safe for even the most delicate fabrics. Fabrics dyed with Blackest Black will be as soft as ever, and as comfortable to wear. Both the dye and soda ash are non-toxic, just don't swallow or inhale either. However, Blackest Black WILL stain your skin, so wear gloves!
Can I wash clothes normally after dyeing?
Yes! After dyeing, wash the dyed items once in the washing machine to remove any excess dye. After that, they won't run! Of course, it is always a good idea to wash your dark and light items separately. See our tips & tricks section for more tips on washing and caring for your black items.
What about clothing with prints?
That depends on the nature of the printing. Most prints will not be affected by the dye at all, but some may change colour.
How does it compare to regular dyes?
Most dyes you find at the supermarket, drug store or craft store are so-called "all purpose" dyes, which will not produce as deep a colouring and will fade after just a few washings (maybe ruining other clothes in the process!). Reactive dyes chemically bond to the fibres, resulting in deeper colour that won't wash out.
Is Blackest Black really the blackest black?
Yes - after extensive research, we believe we've found the blackest clothing dye. One of our tricks: the tiniest, tiniest pinch of blue. It's imperceptible to the human eye, but it adds just that hint of midnight we were looking for.
So, just how black is it?
Turn down your monitor to its lowest brightness, and turn off the lights in the room. Close the door and window blinds. Now close your eyes.
Do you have any other colours?
No. Only black.
Is there anything blacker than Blackest Black?
In 2008, researchers created a material composed of vertically-aligned carbon nanotubes, which reflects only 0.045% of incoming light by trapping it in nanoscale gaps, making it the darkest material ever made by man.
Couldn't you...
We checked. Unfortunately, it is unsuitable for creating dyes.
