1. According to Dyeing Material Form   Yarn Dyeing Machines Designed for dyeing yarn in various forms (e.g., skeins, cheese cones, packages). Cheese Dyeing Machines: Use cylindrical yarn packages (cheeses) immersed in dye liquor, ideal for uniform dyeing of cotton, polyester, and blends. Skein Dyeing Machines: Process loose yarn skeins in rotating baskets, suitable for specialty fibers like wool or silk. Fabric Dyeing Machines Handle woven or knitted fabrics directly. Jet Dyeing Machines: Use high-pressure dye liquor jets to circulate fabric through a closed system, reducing tension and suitable for delicate materials. Jigger Dyeing Machines: Roll fabric onto a beam immersed in a dye bath, ideal for heavyweight fabrics like denim. Winch Dyeing Machines: Transport fabric through a dye bath using a winch mechanism, suitable for medium to heavy fabrics. Garment Dyeing Machines Dye finished garments, often with stone-washing or distressing effects. Rotary Drum Dyeing Machines: Similar to washing machines, tumbling garments in dye liquor for even coloration.   2. According to Operation Mode   Batch Dyeing Machines Process materials in discrete batches, suitable for small to medium production runs and frequent color changes. E.g., cheese dyeing machines, jiggers, and most garment dyeing systems.   Continuous Dyeing Machines Feed materials through a continuous dyeing line for high-volume production. Pad-Batch Dyeing Machines: Pad fabric with dye, then roll it for batch-wise fixation, balancing efficiency and color variety. Pad-Steam Dyeing Machines: Combine padding with steam fixation for rapid processing, ideal for cotton and cellulosic fibers.   3. According to Dyeing Medium   Water-Based Dyeing Machines The most common type, using water as the dye solvent. Equipped with heating systems to control dyeing temperature (e.g., jet dyeing machines for reactive dyes). Non-Aqueous Dyeing Machines Use alternative solvents (e.g., supercritical CO₂ or organic solvents) for eco-friendly dyeing. Supercritical CO₂ Dyeing Machines: Reduce water usage and eliminate chemical waste, suitable for synthetic fibers.   4. According to Pressure and Temperature   Atmospheric Dyeing Machines Operate at normal pressure (1 atm), suitable for dyes that fix at low temperatures (e.g., acid dyes for wool). High-Pressure Dyeing Machines Operate at pressures above 1 atm (up to 3 atm) and temperatures up to 140°C, ideal for polyester dyeing with disperse dyes to ensure dye penetration.   5. Specialized Dyeing Machines   Print-Dyeing Combined Machines Integrate dyeing and printing functions for patterned fabrics. Eco-Friendly Dyeing Systems Incorporate low-liquor ratio technology or recycling systems to reduce water and chemical consumption. Digital Dyeing Machines Use inkjet technology for precise color application, suitable for customized or small-batch production.
