Using clothes fabric dyes such as Dylon is an effective method to restore faded black or navy garments to their original vibrancy and richness.
While you can try various colours, sticking to shades similar to or slightly darker than the original fabric dye will yield more predictable results.
Only natural fibres such as cotton, wool and linen can be dyed. In the case of mixed synthetic and natural fabrics (e.g. 50% polyester, 50% cotton), dyeing is possible, but may result in a less intense colour.
Ensure that the stitching matches the desired final colour, as lighter stitching may contrast with the deepened or altered hue of the dyed garment.
Verify that the stitching is made of natural fibres. Synthetic thread used in the stitching of hems, for example, cannot be dyed. If the garment's label indicates synthetic stitching, proceed only if it perfectly matches the deepened or altered colour of the dyed garment.
You can dye clothes by hand in a bowl or use a washing machine. Both methods require the addition of salt. Once dyed, launder the garment in a separate cycle and then run an extra cycle to clean the washing machine. Finally, wipe the rim of the door with kitchen paper to eliminate any remaining dye residue.
Always adhere to the manufacturer's guidelines.
