Update drab colour plush textiles such as velour with fabric dye. Velour may seem challenging to dye because of the pile. Read the fabric content label prior to choosing a dye solution. Cotton velour requires fibre reactive dyes, while polyester velour calls for disperse dye. Natural fibre reactive dye bonds around the cellulose fibre molecule forming a permanent colour bond. Fabric dyeing can cause natural shrinkage of the original width and length dimensions. Always remember to adjust patterns by adding shrinkage percentages to the width and length prior to dyeing velour fabric.
Pour hot water in a sturdy plastic container or bucket. Small containers not covering the entire piece of fabric with the dye bath produces a spot-dye or an uneven colour tone. If you are working with cool water reactive dyes, refer to your brand's temperature requirement.
Wear latex gloves, a respirator and old clothing prior to mixing. Dye often splatters when immersing and removing the fabric and can permanently damage the garments you are wearing. Dyes release toxic fumes so it is best to work in a well-ventilated area.
Add the reactive fabric dye to the hot water and blend with a mixing stick. Use a plastic spatula to break apart any dye clumps that can form at the bottom of the container. If the clump seeps into the velour, it results in unwanted saturated colour spots.
Add 1 tsp table salt as you continue to stir the dye. Read your brand's instructions for exact measurement requirements. Certain dye brands do not require salt.
Unfold the velour fabric. Immerse one end into the dye bath and continue to feed the remaining fabric into the container until it is fully covered with dye.
Stir the fabric in the container to saturate all sides of the velour. Make sure the fabric does not bunch or fold, preventing the reactive dye from bonding evenly to the velour fibres and pile.
Let the fabric sit in the dye bath according to your brand's instructions. Most brands suggest a minimum of 30- to 40- minutes.
Remove the velour from the dye. Rinse in cool water several times until the dye runs clear.
Set the wet velour, pile side facing up, on a mesh fabric drying rack to air dry for a minimum of 24 hours. This process allows the dye to thoroughly set.
Wash out all dyeing containers thoroughly as soon as you have completed the dyeing procedure. If you allow leftover dye colour to set in the container, particles form and can contaminate subsequent dye colours, changing the colour tone or hue. If you are working with washing machine dye packs, rinse the machine out prior to dyeing subsequent colours or washing your clothes.
You can dye light colour velour to a darker shade or colour, but you cannot dye dark colour velour to a lighter hue.
