Yarn-Dyed vs Piece-Dyed Knit: Cost, MOQ, Lead Time

Short answer: piece-dyed (fabric-dyed) means the fabric is knitted in greige and dyed afterwards as a roll — the standard route, with a colour MOQ of roughly 200-400 kg and 2-3 weeks for the dyeing step. Yarn-dyed means the cones are dyed first and then knitted — it adds about 3-5 weeks and typically $0.40-$0.90 per garment on a mid-weight knit, but stripes become part of the fabric, colour fastness is better, and reorders match more reliably. If your design is a solid colour, piece-dye it. If it is a stripe, an engineered panel, or a shade you will reorder for years, yarn-dye it.

This is one of the few sourcing decisions where the cheap option is not the reckless one. Most knit programs should be piece-dyed, and a buyer who yarn-dyes a solid colour body is spending money on nothing. But the reverse error — printing a stripe because yarn dyeing looked expensive on the quote — produces a garment that looks tired after thirty washes.

The Numbers on a Real Order

A 380 GSM brushed-back fleece, 3,000 pieces, two colourways:

Whether that is worth it depends entirely on whether the stripe is the product. If it is, five weeks is a scheduling problem you solve by starting earlier. If the stripe is decoration on a $19 sweatshirt, print it and move on.

Colour Consistency: The Part Buyers Skip

Whichever route you choose, agree the tolerance before bulk:

Conclusion

Piece-dye solid colours. Yarn-dye stripes, engineered panels and long-life hero shades. The premium is real but modest, and the cost of getting it wrong is a garment that comes back from the customer after one season.

What We Run In-House

HONGTEX knits, dyes and finishes under one roof, which means we can quote the same style piece-dyed and yarn-dyed from the same greige base — you get both numbers and both lead times before you choose. Send the artwork or the swatch and we will tell you which route the design actually needs.
