Woven vs Knitted Velvet: What Buyers Get Wrong

Introduction

Two fabrics arrive at your studio. Both are called velvet. Both have a pile you can stroke. One drapes into a column, the other clings and stretches over the hand. Put the same pattern through both and one garment fits while the other does not.

The reason is not quality. Woven velvet and knitted velvet are different structural classes of textile, and almost every property a garment developer cares about follows from that difference — stretch, dimensional stability, seam behaviour, pilling, how the cloth takes dye, and how much it costs per metre.

This matters because the two are routinely quoted interchangeably in enquiries. A supplier who runs knitting machines will quote you a knit when you asked for a woven cloth, and the price will look attractive. It is not the same product. This guide sets out what actually differs, from a mill that weaves velvet and also supplies knitted stretch velvet, so the comparison is not a sales argument in either direction.

The Structural Difference in One Paragraph

Woven velvet is built from two warp systems. Ground warp and weft form a stable base cloth; a separate pile warp is carried over wires or between weft picks and then cut, which is why the pile stands up as a dense, even surface. The interlacing is at right angles, so the cloth resists distortion along both axes.

Knitted velvet is built from interlocking loops. A ground yarn and a pile yarn are knitted together on a circular or warp-knit machine; the pile is then cut or brushed. Nothing in the structure is straight, so the cloth can move in any direction — which is exactly what gives it stretch, and exactly why it changes dimension under tension.

Everything below is a consequence of that paragraph.

Side-by-Side: The Properties That Decide the Garment

Read the table as a set of trade-offs rather than a ranking. Knitted velvet is the correct choice for a body-con dress; it is the wrong choice for a structured coat. The error buyers make is not picking one over the other — it is picking one while specifying the other.

Why the Cost Gap Exists

Buyers often read the price difference as evidence that one supplier is cheaper than another. It is not. The two fabrics are produced on different machines at different speeds:

• A knitting machine produces a tube or flat cloth at high linear speed from a relatively simple yarn path. Setup is quick, and the machine can be re-configured between styles in a short time.
• A velvet loom carries a separate pile-warp system, usually with wires or a double-cloth arrangement that has to be cut apart. Production speed per metre is far lower, the warp preparation is substantial, and changing a pattern or width is a bigger intervention.

The consequence for a buyer is practical: the woven-versus-knitted price gap is largest at small quantities and narrows as volume rises, because the woven line's fixed setup is being amortised. A quote that shows knitted velvet at a large discount on a 300-metre order is behaving normally. A quote that shows the two nearly equal at 300 metres is worth questioning.

Four Things Buyers Get Wrong

1. Substituting one for the other in an approved pattern

This is the most expensive mistake on the list. A block drafted for a stable woven cloth, cut in a knitted velvet with 4-way stretch, will come out larger and will hang differently. Grading does not save it; the pattern has to be re-fitted. If the substitution is made after the sample has been approved, the entire fit round is repeated.

2. Judging construction from a photograph

Both fabrics photograph as velvet. Weight does not distinguish them — our woven burnout range and our knitted stretch velvet overlap around 250 g/m². The only reliable field test is to take a small piece and pull it gently in both directions: a knitted velvet gives noticeably and recovers, a woven velvet resists.

3. Assuming colour will match across constructions

Viscose/nylon and polyester/spandex take dye by entirely different mechanisms, and the pile reflects light differently. The same Pantone reference will not produce the same visual result on both. If a range mixes the two constructions — common in a collection with both tailored and stretch pieces — plan for two lab dips and accept that the match will be close rather than identical.

4. Specifying upholstery in a knitted velvet

Upholstery is judged on abrasion resistance and stability under sustained load. A knitted ground stretches and can bag at the seat or arm within months. If a knitted velvet is proposed for a furniture application, ask for a Martindale abrasion result and an explicit statement of stretch direction before approving.

How to Tell What You Have Been Offered

Six checks, all doable with a sample in your hand and none requiring a lab:

If a supplier cannot tell you which of the two they are offering, that is itself information. A mill knows its own machines.

Tests That Actually Distinguish Performance

Standard test lists are usually copied between buyers without regard to construction. These are the ones that matter for velvet, and the two columns are not the same:

One note on the last row: stretch and recovery has no single universal standard in common commercial use, so the method has to be written into the order. A supplier who reports a stretch figure without stating the method has given you a number you cannot compare to anything.

Which One for Which Product

Stated plainly, because this is where most of the value is:

• Body-con dresses, fitted tops, leggings, dance and costume wear: knitted velvet. The stretch is the point.
• Structured coats, tailored jackets, capes, formal abaya: woven velvet. You need the cloth to hold a shape.
• Burnout and devoré effects: woven, essentially always. The process depends on a stable ground that survives where the pile is removed.
• Bridal overlays and sheer layering: woven burnout, because the open ground is dimensionally stable and does not distort over a fitted underlayer.
• Upholstery and cushions: woven, for abrasion and stability.
• Children's and easy-care garments: either, but check pilling and wash stability carefully; knitted is easier to fit, woven is easier to keep looking new.

Our own position: we weave velvet in-house at our mill in Fengqiao, Zhuji — burnout and solid-dyed constructions on viscose/nylon — and we also supply knitted stretch velvet in polyester/spandex where the end use genuinely calls for stretch. We quote both, and we will tell you when the answer is the other one.

Frequently Asked Questions

Is knitted velvet cheaper than woven velvet?

Usually yes at the same visual quality, and the gap is structural rather than a matter of supplier margin. Knitted velvet runs at high linear speed on a simpler setup; woven velvet needs a separate pile-warp system at much lower production speed. The lower price reflects different performance limits, not a bargain.

Can I substitute knitted velvet for woven velvet in an existing pattern?

Not without re-grading. A block drafted for a stable woven cloth cut in a stretch knit will come out larger and hang differently, and seam behaviour changes. Budget for a fit round, and expect the colour to be close rather than identical.

Which velvet is better for upholstery?

Woven velvet, in almost every case. Upholstery is judged on abrasion resistance and stability under sustained load, and a stable woven ground performs better on both. Ask for a Martindale result and a statement of stretch direction before approving a knit for furniture.

Does woven velvet have any stretch at all?

Standard woven velvet has no meaningful stretch — a small bias give is not elasticity and should not be relied on. If you need stretch in a woven velvet, elastane must be added to the ground, which changes the specification and the price. Ask explicitly where any stretch comes from.

Why does knitted velvet pill more?

A knit structure traps short fibres at the surface more readily than a tightly interlaced woven ground, and loop geometry lets fibre ends work loose under abrasion. If pilling matters, specify a Martindale or pilling-box result rather than accepting an assurance.
