For procurement teams evaluating a knitted fabric or commission dyeing/printing supplier, three questions recur in almost every conversation: how large is the minimum order, how and when will I see the sample, and when will the fabric reach my warehouse. Although these three headings look like separate line items, they are in fact variables of the same equation. The number of colours and the fabric weight tolerance determine the minimum order (MOQ); the type of sample approved sets the starting point of the lead time; and the sample-approval discipline you adopt lowers the risk of reruns/returns in bulk production. This page opens up that equation from the perspective of a single coordinator — in-house knitting plus a vetted contract network; instead of abstract promises, it shows which step triggers what.
What does MOQ vary with in knitted fabric, and why is there no single figure?
The reason MOQ cannot be reduced to a single figure is that knitted fabric production works on batch logic. Cost and repeatability create a threshold at three points:
- Minimum per colour: Each colour is a separate dye batch. A reactive dyeing bath below a certain load is neither economical nor repeatable; a small quantity of the same colour is, proportionally, the most expensive scenario. An order calling for five colours is, in practice, the sum of five separate minimums.
- Minimum per weight/quality: A given single jersey, interlock or rib quality requires a specific machine setting and yarn feed. Different weights in the same colour mean separate knitting and finishing set-ups.
- Process depth: Greige fabric, dyed fabric and printed fabric are subject to different minimum thresholds. Printing (for example pigment or reactive printing) carries an additional preparation step and so brings its own lower limit.
For this reason the industry usually talks about MOQ as a "colour × weight × process" matrix. Expecting the same threshold for a single-colour, single-weight, plain-dyed order and for a multi-colour, multi-weight, printed collection is misleading. Coordinating knitting, dyeing and finishing under one point of contact across a vetted contract network provides an advantage here: because the minimums for intermediate transport and intermediate stock disappear, flexibility of combination increases. Even so, the specific kg threshold depends on the structure of your order; rather than quoting a single figure, we recommend defining it together according to your combination.
Factors that push MOQ up and down
| Factor | Effect on MOQ | Why |
|---|---|---|
| Number of colours | Up | Each colour is a separate dye batch; the bath needs an economical load |
| Variety of weight/quality | Up | Each weight is a separate knitting and finishing set-up |
| Adding printing | Up | Extra preparation (screen/strike-off) and a separate minimum |
| Speciality yarn (e.g. TENCEL, rPET) | Up | Yarn procurement batch and certificate tracking |
| Single colour, single weight, plain dye | Down | A single batch; the most efficient scenario |
| Standard/stock quality selection | Down | Ready recipe and set-up, the option to combine batches |
Which sample type do I request, for which decision?
A sample is not "seeing a piece of fabric"; it is committing a specific risk to a decision. Trying to verify the wrong question with the wrong sample type is the most common cause of lost lead time and cost. The four types should be distinguished by their purpose:
- Hanger / quality sample: Used to assess the fabric's structure, handle and weight class. It answers the question "is this single jersey or interlock, how does it feel, does the weight band suit me?" Colour is not yet your target.
- Lab-dip: A small dyed sample prepared solely to confirm the colour. It is assessed against the target colour with a ΔE<1 tolerance; it is viewed under different light sources to reveal the risk of metamerism. The approved lab-dip is the reference for bulk dyeing.
- Strike-off: A sample prepared for the print. It confirms pattern registration, colour separation, repeat and the behaviour of the print on the fabric. The lab-dip approves the colour; the strike-off approves the print.
- Bulk / roll (production) sample: A sample taken from the actual batch under real production conditions. It is the bridge between the lab-dip and strike-off and the bulk; it closes the question "does the approved sample also hold in series production?"
The correct sequence narrows risk step by step: structure first (hanger), then colour (lab-dip), then print (strike-off), and lastly series consistency (bulk). Skipping this chain — for example, moving to bulk dyeing without approving the lab-dip — puts the whole batch at risk when a ΔE deviation appears.
Sample type × purpose × typical input
| Sample type | What it approves | Typical input (requested from you) |
|---|---|---|
| Hanger / quality | Structure, handle, weight class | Quality name or target structure, weight band, composition |
| Lab-dip | Colour (ΔE target) | Pantone/standard reference or physical colour sample, light-source preference |
| Strike-off | Print: pattern, registration, colour separation | Vector/high-resolution pattern file, repeat dimensions, colour codes |
| Bulk / roll | Series production consistency | Approved lab-dip + strike-off, target weight and width (width) |
A practical note: if you are using a certified fibre (for example within the scope of GOTS/GRS/RCS), stating this at the sampling stage works in favour of the lead time. Yarn procurement and chain tracking can be started in parallel with the sampling process.
How does the sample approval flow work, and how many rounds does it take?
What most determines the length of the approval flow is the clarity of the brief, before the speed of the manufacturer. If the colour target is unclear, or if approval passes through several people and conflicts, the lab-dip rounds multiply; each round is a delay added in front of the lead time. You can think of the flow like this:
- Brief and reference: Target colour (Pantone/standard/physical sample), quality, weight, width, composition and certificate requirement are clarified.
- Sample preparation: The relevant sample type is produced. For colour, the lab-dip is prepared with the fixation and reactive/disperse parameters of the dyeing recipe.
- Assessment: The sample is measured against the target. For colour, ΔE<1 is targeted on a CMC/ΔE2000 basis; colour fastness expectations (crocking, washing) are also discussed.
- Revision or approval: If there is a deviation, the recipe is revised and a new round prepared. The approved sample becomes the contractual reference for bulk production.
Three practices that reduce the number of rounds: appointing a single, authorised decision-maker; giving the colour reference clearly, either physically or as a calibrated digital value; and setting out the fastness and weight tolerances (GSM tolerance, generally within a ±5% band) in writing from the outset. These three largely prevent the "the third lab-dip didn't hold either" cycle.
Once the order is confirmed, what stages does the delivery process pass through?
After the sample is approved, series production is a linear but interconnected chain. Each step takes the output of the previous one as its input; for that reason a delay at one step spreads to the whole chain. The most tangible benefit of the coordinated contract network is seen exactly here: the loss from changing factory, transport and re-queuing at the intermediate stages is actively managed by a single team.
- Order and planning: The approved sample is taken as reference; yarn, machine and dyeing capacity are planned.
- Yarn: According to the quality requirement, combed, carded or speciality fibre yarn (for example viscose, modal) is procured/confirmed. The yarn count (Ne) directly affects the fabric weight.
- Knitting: Greige fabric is knitted to the target quality (single jersey, interlock, rib, 2×2 rib, piqué, etc.); spirality and dimensional stability are watched here.
- Dyeing: Dyeing is carried out with the approved lab-dip recipe; the ΔE<1 target is monitored.
- Finishing: Through steps such as finishing treatment, sanforising/compacting and stentering, the width, weight and handle are brought to target. If there is printing, it is applied in line with the strike-off approval.
- QC (quality control): Colour (ΔE), weight (GSM tolerance), width, fastness and surface fault control with the four-point system are carried out.
- Despatch: Packing and despatch are planned according to Incoterms terms.
Delivery stages and what is verified at each
| Stage | Output | Verified at this stage |
|---|---|---|
| Order/planning | Production plan | Capacity, yarn and dyeing schedule |
| Yarn | Raw material ready | Yarn count, composition, certificate chain |
| Knitting | Greige fabric | Structure, weight band, width, knitting fault |
| Dyeing | Dyed fabric | Colour (ΔE<1 target), recipe conformity |
| Finishing | Finished fabric | Width, final weight, handle, print quality |
| QC | Approved batch | Colour fastness, GSM tolerance, four-point |
| Despatch | Loaded shipment | Packing, labelling, Incoterms |
What factors affect the lead time, and what can I control?
Lead time is not a single number but a cumulative total. Even at the same mill, two orders can give very different durations, because the variables differ. The main factors that lengthen the lead time:
- Variety of colour and weight: Each additional colour is a separate dye batch, each additional weight a separate knitting/finishing set-up.
- Printing: Strike-off approval and the print step add extra time to the chain.
- Speciality/certified yarn: A fibre not in stock, or a yarn requiring a certificate chain, brings a procurement lead time.
- Sample approval rounds: Each additional lab-dip/strike-off round defers the start of the lead time. It is the most controllable item.
- QC and revision: Reprocessing a batch that falls outside tolerance creates time; that is why pre-approval discipline is the insurance for the lead time.
On the procurement side, the behaviours that work in favour of the lead time are clear: giving the sample brief in full, appointing a single decision-maker, not delaying approvals, and aligning the supply plan with the season/capacity window. Rather than committing to a specific day/week, the healthiest approach is to set out a realistic schedule from the outset according to your combination; this protects both your planning and the production queue.
Factors working for and against the lead time
| Factor | Effect on lead time | Within your control? |
|---|---|---|
| Clear colour reference + single decision-maker | Shortens | Yes |
| Rapid sample approval | Shortens | Yes |
| Standard/stock quality selection | Shortens | Partly |
| Many colours / many weights | Lengthens | Partly (a collection decision) |
| Adding printing | Lengthens | Partly |
| Speciality/certified yarn procurement | Lengthens | No (procurement window) |
| Repeated approval rounds | Lengthens | Yes (through brief quality) |
The whole of this equation in fact rests on a single principle: the earlier you close down uncertainty, the more MOQ flexibility increases, the fewer sample rounds there are, and the more predictable the lead time becomes. In a coordinated flow under a single point of contact, having knitting, dyeing and finishing follow one another with intermediate transport kept short supports this predictability; the ΔE<1 target and the monthly capacity of ~450 tonnes form the infrastructure of series consistency. To plan the supply side of the process in full, you can review the sourcing guide, and for the scope of commission work the commission dyeing/printing/finishing page.
Frequently asked questions
Why isn't MOQ for knit fabric a single figure?
Because knit fabric production runs on batch logic, and MOQ is a "color × weight × process" matrix. Each color is a separate dye lot, each weight requires its own knitting and finishing setup, and the thresholds for greige, dyed and printed processes differ. A five-color order is, in practice, the sum of five separate minimums. The realistic threshold becomes clear based on your combination.
Which sample type approves what?
There are four core samples. The hanger/quality sample verifies the construction, hand and weight class; the lab dip verifies the color (targeting ΔE<1); the strike-off verifies the print (pattern, registration, color separation); and the bulk/top-of-roll sample, taken from the actual lot, verifies mass-production consistency. The correct sequence is construction, color, print, then production consistency; skipping this chain puts the entire lot at risk.
Which color tolerance is targeted in lab dip approval?
The lab dip is assessed against the target shade on a CMC/ΔE2000 basis with a ΔE<1 tolerance. It is examined under different light sources to reveal any metamerism risk, and color fastness expectations such as crocking and washing are also discussed. The approved lab dip becomes the contractual reference for bulk dyeing; the same ΔE<1 target is tracked in mass production as well.
After the order is approved, what stages does the delivery process go through?
The typical flow is order/planning → yarn → knitting → dyeing → finishing → QC → shipment. Each step takes the output of the previous one as its input. Under a single coordinator — in-house knitting plus a vetted, geographically close contract network — these steps proceed under one point of contact with intermediate transport kept short; this eliminates the losses from switching mills, transport and re-queuing, along with the accountability gaps between steps. The duration varies by combination.
What should I do to reduce the number of sample approval rounds?
The clarity of the brief determines the number of rounds more than anything else. Three practical measures help: appointing a single, authorized decision-maker; providing a clear color reference, either physical or as a calibrated digital file; and putting fastness and weight tolerances in writing from the outset (GSM tolerance is usually within a ±5% band). These three largely prevent the "the third lab dip didn't match either" loop.
Which factors most affect the lead time, and what can I control?
Lead time is a cumulative total; the number of colors, the presence of printing, the sourcing of special/certified yarn and the number of sample approval rounds all extend it. What lies within your control is the clarity of the brief and prompt approval: a clear color reference, a single decision-maker and fast sample approval shorten the time. The supply window for special/certified yarn, however, is outside your control.
