Description
Aluminium triformate is a modern alternative mordant that produces bright, clear colours with less harshness on fibres compared to traditional alum. It is effective on both protein and cellulose fibres and works particularly well when paired with tannins. Many dyers appreciate it for achieving brilliance without compromising the handle of the fabric.

Dosage

5–10% WOF (weight of fibre).

Advantages

Produces brighter shades compared to alum.
Gentler on fibres, preserving softness.
Works with both protein and cellulose fibres.
Flexible: can be used hot or cold (bucket method).

Store in a cool, dry place away from direct sunlight. Reseal tightly after use.

Naturally derived and carefully processed from trusted sources to ensure safe use in dyeing and textile applications.

Hot Mordanting Method

Dissolve aluminium triformate thoroughly in warm water.
Do not exceed 70 °C.
Add pre-wetted fibres and stir gently for even absorption.
Mordant for 30–45 minutes, then proceed with dyeing.

Bucket (Cold) Method

Make a 2% solution with (at most) 50 °C warm water. That is 20 grams of powder per liter of water.

Making 10 liter mordant (in a plastic bucket):

10 × 20 g = 200 g of Aluminium Formate are weighed and added to a bucket with warm (max 50ºC) water. Stir.

For smaller amounts (3-5 liter), the powder is dissolved in warm water (approx. 40-60 ºC) and then topped up with cold water.

The mordant can be used immediately.

Time in the mordant;

At 50ºC 1-2 hours. At room temperature 8 hours.

There is no upper limit for mordanting times, so you could keep your fibre in the bucket and leave it there until you need it.

The next batch of fabric can be mordanted in the same bucket. Times needed will extend each time you use up a bit of the mordant. Top up water if needed
