Fabric Suppliers for Clothing Brands: The Short Answer
If you are a founder or small-label buyer, the safest default is to let your factory source the fabric against a written specification you have approved, and to buy fabric directly only when you have a specific reason, such as a signature fabric, a certified fibre or a mill relationship of your own. Fabric suppliers for clothing brands fall into four groups: mills, converters, stockists and factory-sourced fabric. They differ mainly in how much you must order, how much choice you have and who is responsible when the fabric is wrong.
A fabric is not a single item: it is a fibre, a yarn, a construction and a finish, and a supplier can change any of them while still calling it the same name. The sections below show how to pin each one down. For a broader view of fibres and knits, see our overview of types of fabric for clothing.
Mill, Converter, Stockist or Factory: Who Sells Fabric?
Before comparing quotes it helps to know who you are actually talking to. Each of the fabric suppliers for clothing brands sits at a different point in the chain, and that position decides what it can offer a small brand.
Mills
A mill makes the fabric: it spins or buys yarn, then knits or weaves it. Mills run large machines and usually work to high minimum orders per construction and colour, so they suit brands with repeat volume and a clear specification. In return you get the most control over the fabric itself and the clearest view of where it came from.
Converters
A converter buys unfinished fabric (called greige or grey goods), then has it dyed, printed and finished, often at several different processors. Converters usually offer a wider range of colours and finishes with lower minimums than a mill, because they manage the dyeing and finishing steps for many customers at once. The trade-off is one more link between you and the mill.
Stockists and jobbers
A stockist holds fabric in stock and sells it by the metre or the roll. Minimums are low and delivery is quick, which makes stock fabric useful for samples and very small runs. Stock lines can be discontinued without warning, so repeat orders may not match, and the supplier may not be able to tell you the full history of the fabric.
Factory-sourced fabric
In this route your garment factory buys the fabric from its own network of mills and converters, and builds the cost into the garment price. It is the route most startups end up with, because the factory combines its fabric volume across customers and handles testing, shrinkage allowances and cutting. You rely on the factory for transparency, so ask for the fabric details in writing.
Four routes to fabric compared
| Supplier type | Typical minimums | Flexibility | Main risk to the brand |
|---|---|---|---|
| Mill | High per construction and colour (typical, varies) | Low once the order is placed; high control over the fabric itself | Large commitment before the garment is proven |
| Converter | Moderate; often lower than a mill | Good choice of colours and finishes | Extra link in the chain; finishing consistency between lots |
| Stockist or jobber | Low, sometimes by the metre | Limited to what is on the shelf | Fabric may not be available again; limited traceability |
| Factory-sourced | Set by the factory and its mills | Depends on the factory network | Less visibility unless you ask for specification and test evidence |
General characteristics, not quotes. Minimums, flexibility and lead times vary by supplier, construction and season, so confirm them for your fabric.
Specify Your Fabric Before Asking Fabric Suppliers for Quotes
A quote is only as comparable as the specification behind it. When you ask for a price on "heavyweight cotton fleece" you will receive offers for different fabrics, and the cheapest will probably be the lightest. Write the fabric down in the same six fields every time, and attach it to your tech pack or request for quotation.
A fabric specification sheet: the six fields
| Field | What to write | Example (illustrative) |
|---|---|---|
| Fibre | Composition by weight, including any stretch yarn | 80 cotton, 20 polyester |
| Weight | Grams per square metre (GSM), with a tolerance either side | 320 GSM, plus or minus a stated tolerance |
| Construction | Knit or weave type and, for fleece, the face and back | Brushed-back fleece, single-face knit |
| Finish | Brushing, enzyme or silicone softening, pre-shrinking, anti-pilling | Pre-shrunk, brushed back, soft hand |
| Width | Usable width between the selvedges, because cutting efficiency depends on it | Stated as cuttable width, not full width |
| Shrinkage | The maximum change you accept in length and width after washing | Agreed test method and limit in writing |
Illustrative entries only. Use your own figures and agree the tolerance and test method with the supplier.
GSM is the number brands quote most and understand least, because the same weight can feel very different depending on the yarn and the finish. Our fabric GSM guide shows how to read it, and the fleece fabric guide covers the common knits behind the hoodies and sweatshirts that many new brands start with.
Typical fabric weights by product type
Typical, varies
Typical bands only; they overlap and differ between suppliers and constructions. Always specify your own target weight and tolerance.
What an 80/20 Fleece Actually Means
Composition is the easiest field to write and the easiest to misread. A fleece described as 80/20 is made of eighty parts cotton and twenty parts polyester by weight, a ratio many hoodie fabrics use. The split affects handfeel, shrinkage and how the fabric takes colour, which is why the ratio belongs on every specification.
Fibre composition of an example 80/20 cotton-polyester fleece
- Cotton80%
- Polyester20%
A definitional example of how to read a blend ratio, not a recommendation or a Ruhrose product. Ratios are by fibre weight.
Ask whether the ratio applies to the whole fabric or only to the face yarn, and whether trims such as rib are specified separately. Rib on a hoodie is usually a different fabric with its own composition, so list it on the garment bill of materials as its own line.
Minimums, Swatches and Lab Dips
Three terms come up as soon as you start talking to fabric suppliers. A swatch is a small cut of an existing fabric that lets you judge handfeel, weight and drape. A lab dip is a small piece of fabric dyed to match a colour reference, so you can approve the shade before the whole batch is dyed. A minimum order is the smallest quantity a supplier will produce, and it is normally set per construction and per colour rather than per order.
What to request from a fabric supplier
- A swatch of the exact fabric you intend to use, labelled with composition and weight
- A hanger or full-width sample so you can judge drape, direction and finish
- Lab dips for each colour, submitted against a physical colour reference, with the light source stated
- The minimum order per construction and per colour, and whether the supplier can combine colours
- The lead time for stock, for dyed-to-order fabric and for repeat orders
- A written statement of what the supplier will do if the delivered fabric does not match the approved swatch
Approve the lab dip in writing, keep the physical approved piece, and send it onwards with the purchase order. Colour disputes become much easier to settle when both sides can look at the same signed-off reference. If minimums are the sticking point for your first range, our guide to finding denim fabric suppliers shows how the same trade-offs play out in a specialist fabric.
Testing Fabric Before You Commit to Bulk
A swatch tells you how fabric looks and feels on day one. A lab test tells you how it behaves after washing and wear, which is where most disappointments appear. Common checks include shrinkage, colour fastness to washing and rubbing, and pilling, and test methods are published by standards bodies such as AATCC, ISO and others. Ask your supplier or factory which method they use and agree it before testing begins.
If you plan to make claims about the fabric, such as safe from harmful substances, check what the certification actually covers. A label from a scheme like OEKO-TEX covers specific product classes and test criteria, so confirm the certificate number, scope and validity for the exact fabric you are buying rather than relying on a logo.
Where fabric is imported, also check the tariff classification and where the fabric and the garment each count as originating, because both can affect the duty and paperwork. The UK Trade Tariff lets you look up commodity codes, and a customs broker can confirm how they apply to your order.
Brand-Sourced vs Factory-Sourced Fabric: Who Carries the Risk?
You can buy the fabric yourself and send it to the factory, or you can let the factory buy it. Neither is better in every case, but the risk moves with the choice, and it helps to see it side by side before you decide.
Who carries which risk
| Question | Brand-sourced fabric | Factory-sourced fabric |
|---|---|---|
| Who chooses the mill? | You do, and you need the knowledge to do it well | The factory, from its own network, within your specification |
| Who pays upfront? | You pay the fabric supplier before the garment is made | Usually included in the garment price and payment terms |
| If fabric arrives late | Your delay; the factory may reschedule your production slot | The factory manages the delay and the production plan |
| If fabric is faulty | You must show the fault was the fabric and not the making | One party answers for fabric and garment together |
| Cutting waste and shrinkage | You must estimate allowances yourself | The factory plans consumption and allowances |
| Traceability and claims | You hold the records directly | You must request documents from the factory |
General pattern, not a rule. Commercial terms differ between factories, so agree responsibility in writing.
Brand-sourced fabric makes sense for a signature fabric, a certified fibre you must trace yourself or a mill relationship you already hold. It takes more work and carries more risk, so most new brands keep it for the one fabric that defines the product. Our guide to sweatshirt manufacturing shows how fabric choice affects a single product in practice.
Which Fabric Suppliers for Clothing Brands Suit Which Kind of Brand?
The best fabric suppliers for clothing brands are the ones that fit your order size, so the right route depends on how much you will order, how fast you need it and how special the fabric is. The ratings below are indicative and meant to help you shortlist, not to rank suppliers.
Indicative suitability of each route for a small brand
1 dot = low, 5 dots = high
| Mill | Converter | Stockist | Factory-sourced | |
|---|---|---|---|---|
| Works with small quantities | ●●●●● | ●●●●● | ●●●●● | ●●●●● |
| Choice of fabric and finish | ●●●●● | ●●●●● | ●●●●● | ●●●●● |
| Control over the fabric | ●●●●● | ●●●●● | ●●●●● | ●●●●● |
| Speed to first sample | ●●●●● | ●●●●● | ●●●●● | ●●●●● |
| Low workload for the brand | ●●●●● | ●●●●● | ●●●●● | ●●●●● |
Indicative 1 to 5 ratings of typical behaviour, not measured data. Individual suppliers vary widely.
Read across the table for your own priorities. A brand with no technical team and a first order of modest size will usually find factory-sourced fabric the best fit, while a brand with a signature fabric and repeat volume may graduate to a converter or mill.
A Fabric Sourcing Path in Six Steps
Whichever of the fabric suppliers for clothing brands you choose, the order of the work stays the same, and skipping a stage is how most fabric problems start.
From idea to approved bulk fabric
- 1Define the productDecide the garment, the use and the handfeel you want before looking at fabrics.
- 2Write the specificationFill in the six fields: fibre, weight, construction, finish, width and shrinkage.
- 3Request swatchesAsk two or three suppliers for comparable swatches and written specifications.
- 4Approve colourReview lab dips against a physical reference and sign off in writing.
- 5Test the fabricCheck shrinkage, colour fastness and pilling with an agreed method.
- 6Lock the referenceKeep a sealed swatch and compare bulk fabric to it on arrival.
A general path; order of steps two and three can swap when a supplier shows you a fabric first.
Once the fabric is approved, record it as a line on the bill of materials with its supplier, quantity and tolerance, so that every later quote and purchase order refers to the same fabric.
Common Mistakes When Buying Fabric
Most problems with fabric suppliers for clothing brands trace back to a small number of avoidable habits. Buyers describe a fabric by name rather than by specification, so two suppliers quote for different goods. They approve a swatch but not the bulk, so the delivered fabric differs without anyone noticing. They forget that minimums apply per colour, and that colour dyeing adds to the lead time. They also compare price per metre without comparing width, which changes how many garments one metre makes.
Two fabrics at the same price per metre are not the same price if one is narrower, because you cut fewer garments from each metre. Ask for the cuttable width and let the factory estimate consumption per garment before you compare.
Which part of your next fabric order could you not yet describe in writing: the fibre, the weight, the finish or the allowable shrinkage? Start there, because that gap is where the quote will drift.
How Ruhrose Approaches Fabric Sourcing
Ruhrose develops hoodies, fleece, jersey, denim and woven casualwear with production in Bangladesh and UK buyer support. For most new brands we recommend building fabric into development and production, agreeing a written specification first, and sampling the fabric before bulk. If you hold a fabric of your own, we will discuss it early, because supplying fabric changes responsibility for delays and faults.
