Ferrous sulphate
Dyeing auxiliaries
Price range: 4,00€ through 11,00€
The Ferrous sulphate is a chemical compound that contains iron and sulphur. It occurs as green or blue-green crystals and is soluble in water. In the practice of natural dyeing, ferrous sulphate acts as an etchant, fixing natural dyes onto yarns and fabrics and improving their intensity and strength in terms of quality and durability.
It is also used as a modifier to transform colours into greys and blacks, as well as producing darker shades of other natural colours.
It is most used with cellulosic fibres such as cotton, linen or hemp and should be used with caution on protein fibres, as it may make them slightly hard or brittle.
It is important to use it in small quantities to protect the fibres from hardening and cracking.
Dyeing auxiliaries
The Dyeing auxiliaries are essential to ensure uniform application of the natural dye on the textile fibres and correct fixation. Each auxiliary gradually and uniformly releases its acidity or alkalinity, thus promoting optimal dyeing and preventing possible colour changes. Their use ensures excellent, long-lasting results in artisan dyeing.
Doses and timing
Maeko avoids going into details concerning proportions, doses and specific times, leaving such information to those who already have experience in natural dyeing.
It is essential that those approaching this process have the freedom to experiment and adapt the techniques according to their own needs and experience.
Here we offer an extensive showcase, designed to encourage the practice of hand-dyeing and stimulate everyone's creativity.
