I have never come across Aluminum lactate before but it sounds to be an ideal mordant for my purposes. it will be good to compare last year's soya milk mordanted and dyed fabric with this year's using AL instead. Point taken on the scouring too. Definitely getting lazy on that one. Very grateful for you sharing this knowledge.]]> Unknown user https://www.snapdragonlife.com/news/blog/how-to-mordant-wool-for-natural-dyeing/#comment1269 Fri, 24 Apr 2026 22:49:10 +0100 https://www.snapdragonlife.com/news/blog/how-to-mordant-wool-for-natural-dyeing/#comment1268 In reply to Julie VannHi Julie - with cellulose fabrics I mordant with aluminium lactate, which is made from fermenting starches. Soy milk is - as you surmise - a binder, rather than a mordant, creating a thin layer of protein on the fabric which then attaches to the dye pigments. I don't use it as part of my regular practice as doesn't work as well long term as a true mordant. I use aluminium lactate at 5% weight of fibres. Aluminium lactate is a made by the fermentation of food starches like sugar beet. With cellulose fibres the main step that makes a difference long term is a really good and thorough scouring and rinsing before mordanting - not just a quick whizz in a hot wash as I've been tempted to do in the past. This is especially the case with old fabrics where stains can remain hidden until dyeing (though this of course may be exactly what you want, though possibly not on underarms . . . .).]]> Katie https://www.snapdragonlife.com/news/blog/how-to-mordant-wool-for-natural-dyeing/#comment1268 Fri, 24 Apr 2026 12:49:06 +0100 https://www.snapdragonlife.com/news/blog/how-to-mordant-wool-for-natural-dyeing/#comment1267 Unknown user https://www.snapdragonlife.com/news/blog/how-to-mordant-wool-for-natural-dyeing/#comment1267 Fri, 24 Apr 2026 12:39:05 +0100
