Why different fabrics need different dyes
A textile’s fiber chemistry affects how a dye can attach and remain after washing. The complete process matters too: preparation, temperature, pH, fixation and removal of excess dye work together.
Fiber-reactive dye and cellulose
Jacquard describes Procion MX as forming a covalent bond with cellulosic fibers. For a suitable product and fiber, follow the prescribed preparation, fixation and washing stages. The product name does not establish that every garment or blend is compatible.
Other fibers need other assessments
Protein fibers, nylon and polyester have different dyeing requirements. Use the manufacturer’s material guide to select the exact product. A mixed-fiber garment may develop a mixed result because its components do not all respond to the same process.
Dye uptake and fixation are different
An item looking colored in a bath does not prove the color will remain after washing. Excess or unfixed dye must be dealt with according to the product’s instructions. Heat or household additives are not universal substitutes for the correct setting process.
Process conditions have limits
Use the specified temperature; more heat can damage an unsuitable garment.
Use the prescribed additives and quantities rather than combining recipes.
Allow enough movement or use the method specified for the item.
Complete the required washing and aftercare stages.
Record the actual fiber, starting shade and trial conditions.
Plan from the whole item
Thread, coatings, elastic, linings and trims can complicate an otherwise suitable fiber choice. The original shade also affects the result. For an important finished garment, ask a provider about testing and expected variation.
