What is mordanting?

Mordanting is a process used to prepare fabric for dyeing or printing. It involves applying a chemical compound to the fabric, which helps the dye to adhere more permanently. Mordants are typically metal salts, such as alum, iron, or copper.

The mordanting process helps to improve the colorfastness of the dye, making it more resistant to fading and bleeding. It also helps to create a more vibrant and saturated color.

Why do you need to mordant cotton for eco printing?

Cotton is a natural fiber that is not inherently receptive to dye. This means that if you try to dye cotton without mordanting it, the dye will not adhere well and will likely fade quickly.

Mordanting cotton helps to create a chemical bond between the dye and the fiber, which makes the dye more permanent. It also helps to prevent the dye from bleeding or running when it is washed.

There are a number of different mordants that can be used for cotton, each of which produces a different effect on the color of the dye. Some of the most common mordants for cotton include:

• Alum: Alum is a versatile mordant that can be used with a wide variety of dyes. It produces bright, clear colors that are resistant to fading.
• Iron: Iron mordants produce deep, rich colors that are especially well-suited for red and black dyes.
• Copper: Copper mordants produce muted, earthy colors that are perfect for natural dyes.

The type of mordant you use will depend on the desired color and the type of dye you are using.
