Description
What is shredded Mimosa hostilis root bark?
Shredded Mimosa hostilis root bark (shredded MHRB) is the inner root bark of the Mimosa tenuiflora tree, dried and cut into loose fibres. It carries the same tannins and purple-brown pigments as the powder, in a form that is cleaner to handle and simple to strain.
Why choose the shredded bark?
- Easy to strain – the fibres lift out of the pot, leaving a clear dye liquor with less sediment on your fabric.
- Less dust – cleaner to weigh and work with than powder.
- Good for repeated extractions – the same bark can be simmered more than once for lighter second and third baths.
Common uses
Natural dye for fabric and leather
Soak the shredded bark, simmer it gently, then strain and add pre-wetted fibre. Expect pinks, purples and warm browns, shifting with the fibre and mordant you choose.
Soap making
Infuse the bark in water or oil and use the strained liquid to colour cold-process soap in natural tones.
Cosmetic formulation
Strained infusions of tepezcohuite bark are used in handmade balms, creams and masks.
Frequently asked questions
How do I dye fabric with shredded Mimosa hostilis root bark?
Soak the bark overnight, simmer it gently for about an hour, strain out the fibres, then add pre-wetted fabric to the warm dye bath and heat gently for another hour. Our step-by-step dyeing guide covers the full method.
How much shredded bark do I need?
For a medium shade, use roughly the same weight of bark as dry fibre, for example 100 g of bark for 100 g of wool. Half that amount gives lighter tones.
Can I reuse the bark?
Yes. After the first extraction you can simmer the same bark again. The second and third baths give paler, dustier pinks that pair well with the first batch.
Which fibres does it work on?
It dyes natural fibres: wool, silk, cotton, linen and vegetable-tanned leather. Wool and silk usually take the deepest purples and pinks, while cotton and linen lean towards softer, browner shades. Synthetic fibres do not take natural dyes well.
Do I need a mordant?
It is optional, because the bark is naturally rich in tannin. Alum brightens the colour and improves fastness; a small amount of iron in an after-bath shifts it towards grey-purple and brown.
Why choose shredded bark?
The loose fibres strain out of the pot cleanly, create very little dust and need no cutting, which makes shredded bark the most practical form for regular dyeing.
How should I store shredded bark?
In a sealed bag or container, somewhere cool, dry and out of direct light. Kept dry, it holds its colour for a long time.
Sizes and bulk orders
Choose from 500 g up to 100 kg in the weight menu above. Larger sizes suit dye studios, soap makers and resellers who need a consistent batch.
Storage
Keep the bark in a sealed container in a cool, dry place away from direct sunlight. Stored this way it holds its colour for a long time.
