Machine dyeing requires a dye designed for that application and approval for the washing machine. Fiber content, seams, and finishes affect the result; it is not enough for the garment to be washable.
Check the compatibilities
Read the dye instructions and the equipment restrictions. Some procedures apply only to certain machine designs or cycles. If the machine manufacturer excludes dyeing, do not continue even if the package says it is suitable for the washing machine.
Check the fibers, blends, linings, sewing thread, and trim. Different materials can absorb color differently; a garment made of multiple materials is not guaranteed to come out in a uniform shade. The original color also affects the result promised by the product.
Prepare and run the dye cycle
- Check the label, pre-cleaning, and dry weight required by the product chart.
- Prepare the load within the limits of the dye and the machine, leaving enough room for movement.
- Add dye and auxiliaries only as directed by that formula. Do not copy salt, grams, or temperatures from another package.
- Select the indicated phases, including post-wash or rinse when required.
- Remove and dry the garments according to their instructions.
Before the next wash
Check for transferable residue in the drum, folds, and dispenser, and apply the compatible post-cleaning. A permanent stain on plastic does not necessarily mean dye that is still transferring; do not add other chemicals based on appearance alone.
Intentional dyeing is not the method for removing accidentally transferred dye. It also does not guarantee repair of fabric discoloration or damage.
Check the machine's post-cleaning before returning to an ordinary wash; do not assume there is no transfer based on an incomplete inspection.
