Yarn-Dyed vs Piece-Dyed Fabric: What Is the Difference?
Yarn-dyed fabric is dyed before weaving. Piece-dyed fabric is dyed after. Learn how they differ in look, cost, minimum order and use.

The short answer
Yarn-dyed fabric is woven from thread that is already dyed, so patterns like checks and stripes are built into the weave. Piece-dyed fabric is woven in its natural (undyed) state, and the whole length is dyed afterwards. This gives a plain colour.
How they are different
Look: yarn-dyed fabric has depth and a woven pattern on both sides. Piece-dyed fabric has a flat, even colour.
Colour strength: in yarn-dyed fabric the colour usually goes deeper into the fibre. Both can be good or poor, depending on the dye and process, so always test.
Flexibility: undyed fabric can be dyed to order in a new colour quickly, which helps small orders. Yarn-dyed designs need thread dyed and woven for each pattern, so minimums are usually higher.
Cost: yarn-dyed fabric usually costs more per metre than a similar plain fabric.
Which one should you use?
Choose yarn-dyed for shirts, checks, stripes and good-quality casual wear. Choose piece-dyed for plain colours and prints (printing is done on dyed or white fabric), and when you need quick colour changes with low minimums.
