Knit vs Woven Fabric: The Difference and Why It Matters for Sourcing

The Short Answer

Knit and woven are the two ways almost every apparel fabric is made. A woven fabric is made by interlacing two sets of yarn at right angles on a loom. A knit fabric is made by pulling yarn through itself in rows of interlocking loops. That single difference in construction decides how a fabric stretches, drapes, frays, shrinks and recovers, and it also decides which kind of factory sews it.

For a brand, knit vs woven is not a textile-school question. It is one of the first decisions in a product brief, because it determines the fabric supplier, the sewing machines, the pattern, the test reports and even the tariff chapter your goods are classified under when they enter the US.

This guide explains how each fabric is made, how to tell them apart, which garments use which, and what changes in sourcing when you move from a knit product to a woven one.

What Is Woven Fabric?

Woven fabric is made on a loom from two sets of yarn. The warp yarns run the length of the fabric and are held under tension. The weft yarns, also called filling or picks, are passed across the warp, going over and under the warp yarns in a set pattern. The result is a grid of yarns crossing at right angles.

Because the yarns are locked into that grid, a woven fabric is stable along its length and width. It has little natural stretch in either direction; it only gives on the bias, the 45-degree diagonal. Any real stretch in a woven, such as stretch denim or stretch chino, comes from elastane blended into the yarn, not from the construction.

The three basic weaves

Jacquard and dobby are not separate weaves so much as loom mechanisms that let the weaver control individual yarns and build patterns into the cloth. Terry towelling is also usually woven: an extra set of warp yarns is woven in loose to form the loop pile on one or both faces.

What Is Knit Fabric?

Knit fabric is made by forming yarn into loops and drawing each new loop through the one before it. The vertical columns of loops are called wales and the horizontal rows are called courses. Because loops can open and close, a knit stretches even when it contains no elastane, and it recovers its shape when released.

There are two families of knit fabric.

Weft knits

In a weft knit, the yarn travels across the fabric, forming a row of loops one after another. This is the family behind most casual apparel, and it is produced on circular knitting machines (which make a tube of fabric) or on flat knitting machines (used for sweaters, collars and cuffs, and fully fashioned panels).

Warp knits

In a warp knit, each yarn runs roughly lengthwise and loops into its neighbours in a zigzag. Warp knits such as tricot and raschel are made on flat warp knitting machines. They run less than weft knits and are used for mesh, lingerie, swimwear and activewear linings, and some technical fabrics.

Knit vs Woven: The Main Differences

The construction difference shows up in every property a buyer cares about.

Neither construction is better in general. The right choice depends on what the garment has to do.

How to Tell Knit from Woven Fabric

You can identify most fabrics in under a minute with a sample or a finished garment in hand.

Which Garments Are Knit and Which Are Woven?

Most product categories have a default construction. Knowing it helps you brief a factory correctly and avoid asking a woven specialist to quote a jersey programme.

Usually knit

Usually woven

Some categories cross over. Jersey sheets are knit; knit denim exists; and an overshirt can be made from a heavy brushed knit or a woven flannel. When the category is ambiguous, state the construction explicitly in the tech pack rather than leaving the factory to infer it.

Why Knit vs Woven Matters When You Source

This is where the distinction stops being academic.

It changes which factory you need

Knit garment production and woven garment production use different equipment and skills. Knit lines run overlock, coverstitch and flatlock machines that sew a seam able to stretch with the fabric. Woven lines rely on lockstitch machines, buttonholers and pressing, and on finishing seams so the cut edge cannot fray. Many factories specialise in one or the other, and a factory that is excellent at T-shirts and hoodies may not be the right supplier for button-down shirts. Matching the brief to the right kind of factory is the first filter.

It changes the fabric supply chain

Knit garment factories often buy yarn and have fabric knitted and dyed to order, sometimes in their own facilities or through nearby knitting mills and dyehouses. Woven fabric generally comes from weaving mills, and the mill's own minimums per colour and per construction can become the binding constraint on a small order. Ask early whether the factory is buying a stock fabric or developing one for you, because that affects both the minimum and the lead time.

It changes the pattern and the fit

Patterns for knits account for stretch; a fitted knit top can be cut smaller than the body measurement and still fit. Wovens need ease, darts, pleats or openings to move. A pattern made for one construction does not transfer cleanly to the other, so changing a style from woven to knit, or the reverse, is effectively a new product with a new sample round.

It changes testing and tolerances

For knits, ask for shrinkage results after washing in length and width, a spirality or seam-twist check, and a stretch and recovery figure for anything containing elastane. For wovens, ask for dimensional stability, seam slippage, and tear and tensile strength where the garment will be stressed. Put the agreed tolerances in the tech pack so the pre-shipment inspection can check against them.

It changes the US tariff classification

The Harmonized Tariff Schedule of the United States places knitted or crocheted apparel in Chapter 61 and apparel that is not knitted or crocheted, which in practice means woven, in Chapter 62. The same product, for example a men's cotton shirt, can carry a different HTS code and a different duty rate depending on whether the fabric is knit or woven. Confirm the classification with your customs broker before you price the product, and make sure the construction on the commercial invoice matches the goods.

How to Specify Knit or Woven Fabric in a Tech Pack

A clear fabric line saves a sample round. For either construction, include:

The fabric line sits inside the bill of materials of a full specification package; see what goes into a tech pack for the other sections a factory needs to quote.

Knit and Woven Production in Turkey

Turkey produces both knit and woven apparel at scale, and its textile industry runs from spinning and knitting or weaving through dyeing, finishing and garment manufacturing. Different regions are known for different strengths, from fashion and knitwear to woven fabrics, home textiles and denim, which is why the construction of your product is one of the first things to settle before a factory is matched.

Through SourceBridge's textile sourcing service, a brief goes to two or three pre-vetted factories within 24 hours, matched to the product type and construction. The published starting point for textile orders is 300 units per style. Samples typically take 7 to 14 days to produce plus 5 to 7 days by courier, production runs 4 to 8 weeks depending on complexity, and a pre-shipment inspection is checked against the approved sample.

FAQ: Knit vs Woven Fabric

What is better, knit or woven?

Neither is better in general. Knits are better where the garment needs stretch, softness and freedom of movement, such as T-shirts, activewear and loungewear. Wovens are better where the garment needs structure, a crisp finish and resistance to abrasion, such as shirts, trousers, denim and outerwear.

How do you tell the difference between knit and woven fabric?

Stretch it across its width: a knit gives and springs back, a woven without elastane barely moves. Then look closely at the surface. Knits show columns of V-shaped loops; wovens show a criss-cross grid or diagonal twill lines. A woven edge frays, while a jersey edge tends to curl.

Are T-shirts woven or knit?

T-shirts are knit, almost always from single jersey. Some use slub jersey, interlock or a rib for fitted styles. A shirt made from woven fabric would usually be called a shirt or blouse rather than a T-shirt.

Is 100% cotton a knit or woven fabric?

Cotton is a fibre, not a fabric construction, so 100% cotton can be either. Cotton jersey and cotton fleece are knits; cotton poplin, cotton twill and denim are wovens. The label tells you the fibre; the construction has to be stated separately.

Is denim knit or woven?

Denim is a woven fabric, a warp-faced twill usually made with indigo-dyed warp yarns and undyed weft yarns, which is why the inside of jeans is lighter than the outside. Knit fabrics printed or dyed to look like denim exist, but they are not true denim.

What are the downsides of woven fabric?

Woven fabric has little natural stretch, so garments need ease and closures to fit and move. Cut edges fray and must be finished, cotton and linen wovens crease easily, and patterns are less forgiving of fit errors than knit patterns.

What are the downsides of knit fabric?

Knits can shrink more in length, twist at the side seams after washing if not properly finished, pill or snag, and lose shape if the yarn or construction is too light for the garment. These risks are managed with the right fabric weight, pre-shrinking and agreed wash-test tolerances.

Does knit or woven affect the minimum order quantity?

It can. The garment factory's minimum is usually set per style and colour, but the fabric often has its own minimum per colour, and woven fabric developed to order from a weaving mill can carry a higher minimum than a stock knit. SourceBridge's published starting point for textiles is 300 units per style; confirm the fabric minimum for your construction at the quote stage.
