THE SOLUTION-DYE PROCESSSolution dyed fiber v.s Piece dyed fiber Saves energy In simple terms, solution-dyeing is a technique that reduces the use of water and chemicals when dyeing fabrics compared to traditional wet processes. The solution-dye process involves mixing the colour pigments in with raw or recycled polyester, before they are made into filaments. By dyeing the fibres without water, there is a reduction in chemical waste, energy usage and bi-products such as CO2. Solution dying is a technique used to colour synthetic textiles such as acrylic, nylon and polyester. The solution dye process differs from traditional fibre or piece dyeing since it involves one less process step. In the solution dye process, pigments are added to the liquid polymer solution before synthetic fibres are extruded. Compared to traditional fibre dyeing – where colour is applied in a second process step; after fibres have been extruded. The solution process saves approximately 80% water, 20-30% dyestuff, 80% other chemical agents and it also requires less energy. |
