"Dyeing" covers three different processes, and which one you want depends on what you're actually after. Reactive dye bonds at the fibre level before the garment is cut and sewn — it's the standard for solid, colourfast cotton shades that won't fade or shift. Pigment dye sits on the surface of the fabric rather than bonding into it, which gives that soft, slightly worn-in look brands often want for streetwear, at the cost of some colourfastness over time. Garment dye means dyeing the finished, already-sewn piece rather than the fabric beforehand, which produces the faint tonal variation and lived-in character you can't get from piece-dyed fabric.
We offer all three, plus tie-dye and acid wash, as part of full garment manufacturing — dyeing the pieces we cut and sew to your spec, not applying colour to stock blanks. For a specific shade, we colour-match to Pantone or your reference and confirm it on a physical lab dip before bulk production runs, so you're approving the actual colour, not a screen render of it.
Dyeing is also one of the more environmentally consequential steps in garment production — it's water- and chemical-intensive by nature. We place it only with partner dye houses that run wastewater treatment, and we offer GOTS-compatible processes for brands whose organic claim needs to hold up through this stage too, not just at the raw-fibre stage.
Reactive dye for colourfast solids, pigment dye for a soft worn-in look, garment dye for lived-in tonal variation — we'll recommend the right one for the effect you want.
We make the garment and book and inspect its dyeing at partner dye houses — one company answerable for both, with the colour confirmed on a physical lab dip before bulk.
Custom-dyed runs from 150 pieces per style, per colourway.
Wastewater treatment as standard, with GOTS-compatible dyeing available for organic-certified lines.
1. The colour standard. A Pantone TCX reference, a fabric swatch or a garment you want matched. A physical swatch matches better than a screen colour.
2. Lab dips. The dye house dyes small samples of your actual fabric, usually two or three versions close to the target, for you to approve under daylight-equivalent light.
3. Bulk dyeing. The approved recipe is dyed in production batches. Each batch is a dye lot, and two lots of the same recipe can differ slightly, which is why matching pieces should come from one lot.
4. Shade check. The bulk fabric is checked against the approved dip before cutting, then again on the finished garment.
Piece dyeing, where the fabric is dyed before cutting, gives the most even colour and suits most orders. Garment dyeing, where the sewn garment is dyed, gives a washed, lived-in look and slightly more variation from piece to piece. Our minimum is 150 pieces per style and colour either way, because each colour is its own dye run.



Dyeing is the stage brands most often assume happens where their garments are sewn. It does not, here or at most factories in Bangladesh. This is the plant your fabric actually goes to, filmed on one of our visits, followed by the stage that happens on our own floor.
Colour is the most common reason a reorder disappoints a brand, so it is worth knowing exactly where in the chain your shade is decided and who carries the risk when it moves.
You approve a physical dip rather than a Pantone reference on a screen, and that dip stays on file so a second order is matched to the same physical standard as the first. We place the work and we carry the result; you never get handed a dye house's phone number when a shade drifts.
Wonderful people to work with — very professional and knowledgeable, also accommodating to the needs of their customers.
I have had a very good experience with this company. They are very friendly, professional, and provide fast service. They speak fluent English, which makes communication very easy. The quality of their manufacturing is excellent. I have no doubt in recommending this company to anyone looking for a reliable manufacturing partner in Bangladesh.

Dye cost is mostly about lots. Every colour is its own dye lot with its own minimum, and the process you choose changes what gets dyed, and when.
The mill dyes in lots with a minimum number of kilos per shade, and that minimum is the floor under each colourway. This is why the 150-piece minimum applies per colour rather than per order: a style in five shades is five lots, five minimums and five lab dips, however small each one is.
Reactive dye happens at fabric stage, before cutting, and is the baseline. Garment dye treats finished, sewn pieces in a batch after sewing, which adds a second handling stage, requires the pattern to allow for shrinkage in the bath, and means thread and labels go through the dye too. Pigment dye sits between.
Matching a specific Pantone or reference is a development round: a lab dip is made, compared, and sometimes remade until it is approved. Each round is a one-off cost per shade, so a brand that accepts a standard shade pays less than one that needs a bespoke match on every colour.
Deep and dark shades take more dyestuff per kilo of fabric than pale ones, and blacks the most of all, so the same fabric costs more per kilo in navy than in ecru. This is a mechanical fact of dyeing rather than a factory policy, and it shows up on every quote.
These are hand processes applied garment by garment rather than kilo by kilo, so their cost is labour per piece and it does not fall much with volume. Some variation between pieces is inherent in the technique, and the sample sets the range you are approving.
Holding an organic claim through dyeing means approved dyestuffs, a certified processor and wastewater treatment, with paperwork for each fabric lot. The chemistry costs a little more per kilo and the administration favours fewer colourways, which is worth knowing before a collection is planned in eight shades.
Yes, both, plus acid wash, on garments we cut and sew to your spec rather than on stock blanks. Garment dyeing colours the finished piece, so everything sewn into it goes through the bath too, thread and labels included, and the pattern has to allow for the shrinkage the bath causes. In return you get the softer hand and slightly uneven, lived-in depth that vintage-leaning labels want. Tie-dye, whether hand-tied spiral, crumple or dip, and acid wash are hand processes applied garment by garment, so the cost is labour per piece and does not fall much with volume. No two tie-dyed pieces are identical: the approved sample sets the range of variation you are signing off, and you should market that variation rather than fight it. If you need every unit to match closely, tie-dye is the wrong choice, and we will say so before you commit to a colourway you cannot repeat.
Yes, to a Pantone reference or a physical swatch, and you approve the colour on a lab dip of your actual fabric before anything goes into bulk. That step matters because a colour on a screen, a colour on paper and a colour on knitted cotton are three different things. Matching a bespoke shade is a development round: the dip is made, compared with your reference and sometimes remade until you sign it off, and each round is a one-off cost per shade, so accepting a standard shade costs less. The approved dip stays on file against your style, finished garments are checked against it under controlled light before packing, and a lot that misses it is re-run at our cost. Two honest limits. Dye is chemistry, so separate lots sit within a tolerance rather than landing identical. And intense brights and true blacks are harder to hit on organic cotton than conventional, because the fibre takes dye slightly differently.
Reactive dye bonds chemically with the cotton fibre, so colour is fast, deep and washes well — it is the standard for quality cotton knitwear and what we use by default. Pigment dye sits on the surface held by a binder rather than bonding; it gives the soft, slightly faded, vintage look brands sometimes want deliberately, but it fades faster with washing and UV, so it is a stylistic choice rather than a quality one. Garment dyeing is a different axis entirely — it describes when you dye rather than how, colouring the finished garment instead of the fabric. That gives a softer hand and characterful unevenness, and it shrinks the piece during the process, so patterns must be cut oversized to compensate. That last point is a construction decision, not a finishing one.
Usually, yes, because it moves dyeing to after sewing, which adds a second handling stage. Reactive dye is applied at fabric stage, before cutting, and is the baseline. Garment dye treats finished, sewn pieces in a batch, so the pattern must allow for shrinkage in the bath and thread and labels go through the dye as well. Pigment dye sits between the two. Beyond the method, three other things move a dyeing quote. The number of colourways, because each is its own lot with its own minimum. Bespoke colour matching, because every lab dip round is a one-off cost per shade. And depth of shade, because navy and black take more dyestuff per kilo than ecru, with black the most of all. GOTS-compatible dyeing also costs a little more per kilo. Tie-dye and acid wash are priced as labour per piece. We quote the dyeing for your order once the method, colourways and shades are fixed.
150 pieces per style, per colourway, and with dyeing the per-colour part matters more than on any other process. The mill dyes each colourway as a separate lot with a minimum number of kilos per shade, and each needs its own lab dip. A style in four shades is therefore four lots, four minimums and four lab dips, so at least 600 pieces, not 150 split four ways. Within one colourway you can spread the 150 across your size range. Separate lots also sit within a tolerance of each other, so a shade dyed again for a reorder can land marginally different. If every piece in a shade must match exactly, order the full quantity you need up front and we will book it as one dye lot; for a reorder, the shade is dyed against the original dip we keep on file. Try your own style and colour counts in the MOQ calculator before you plan the range.
More than most, and short of perfect. Your fabric is dyed at partner plants we book and inspect, and we place work only in units that run wastewater treatment as standard rather than as an exception. That is not simply our word for it: GOTS requires every unit handling certified fibre to hold its own scope certificate, restricts which chemicals can be used at all, and requires effluent to be treated before discharge — that is audited by a third party, not self-declared. Where honesty is due: dyeing is water- and energy-intensive by nature, and no treatment plant makes it neutral. We reduce load where we can by dyeing in full lots rather than repeated small batches, and by steering brands toward one colour deep instead of several shallow, which cuts the number of dye runs. If a supplier tells you their dyeing has no environmental cost, they are selling you something. Ask for the certificate number instead.
