Step 1: Types of dyeing stages.
- Fiber/Stock dyeing: Dyeing fibers before spinning (e.g., heather effects).
- Yarn dyeing: Dyeing yarns before weaving/knitting (e.g., checks, stripes).
- Piece dyeing: Dyeing fabric after weaving/knitting, most common method.
- Garment dyeing: Dyeing completed garments.
Step 2: Understanding given processes.
- Jig dyeing: Fabric is passed through dye liquor in open width form.
- Beam dyeing: Fabric is wound on a beam and dyed under pressure.
- Winch dyeing: Fabric is circulated in dye liquor using winch rollers.
- Pad dyeing: Fabric is passed through dye bath and squeezed (padded).
- Jet dyeing: Fabric circulates in a rope form with the help of high-pressure jets.
Step 3: Identifying the stage.
All these methods handle fabric (not yarn or fiber) and are categorized as piece dyeing methods.
Step 4: Conclusion.
Therefore, all listed processes belong to Piece dyeing at the fabric stage.
