The one-line difference

Woven fabric is built from two yarn systems — warp (lengthwise) and weft (crosswise) — interlaced at right angles on a loom, producing a stable grid. Knit fabric is built from a single yarn looped through itself, interlocked in vertical columns (wales) and horizontal rows (courses), producing a flexible structure. Almost every difference buyers care about — stretch, fraying, sewability — follows from this one structural fact.

How to tell them apart on a sample

What changes for your garment

PropertyWovenKnit
Stretch & recoveryStable; needs elastane to stretchInherent stretch from loop geometry
Shape & drapeHolds a crisp silhouette and a sharp creaseSoft drape; can grow or curl
Wind & coverTight weaves can be wind-resistantOften more open and breathable
Cut & sewCuts and sews precisely for tailoringNeeds care to avoid stretch distortion

The GSM trap — same number, two cloths

GSM is mass per area, not construction. A 180 GSM woven poplin is a light, semi-sheer summer shirting; a 180 GSM cotton jersey is a substantial, heavyweight T-shirt. The knit loop structure traps air and adds loft, so the same grammage feels and performs completely differently. Always state knit or woven when you quote or ask for a weight — a single unqualified GSM has caused real sourcing errors.

How strength is measured for each

Wovens have a fixed warp/weft grid, so strength is measured by pulling along one axis: tensile strength (ISO 13934-1/2, ASTM D5034/D5035) and tear strength (Elmendorf, ISO 13937-1 / ASTM D1424). See our tensile & tear guide.

Knits have no fixed yarn direction, so a straight tensile pull is misleading. Bursting strength (ISO 13938-1 hydraulic method, ASTM D3786 ball method) applies multidirectional force until the cloth ruptures — closer to how a knee or elbow loads the fabric in use. The two methods are each correct for their structure; they are not interchangeable.

Which to choose

How we handle it

Nantong Huayuan Textile is an integrated woven mill: yarn dyeing, weaving, fabric dyeing, printing and finishing all run on one site. We do not produce knits. The guidance above is written so you can specify the right structure for each panel; for the woven parts we develop in-house across poplin, twill, oxford, chambray, yarn-dyed shirting and more — see the woven range. Made-to-order runs at 2,000 metres per colour, sampling is charged and credited against the bulk order, and lead time is confirmed in writing at enquiry. Enquiry email: gxy@ntboerli.com.

Common questions

Is knit always stretchier than woven?

Usually, because the loop structure gives inherent stretch. But a dense, stable knit can stretch less than a woven that contains elastane. Always test the actual cloth in the direction you need.

Can the same GSM mean different things?

Yes, and it is a common sourcing error. A 180 GSM woven poplin and a 180 GSM cotton jersey are entirely different cloths. State the construction (knit or woven) whenever you give or ask for a weight.

Why are wovens and knits tested differently?

Wovens have a fixed warp/weft grid, so strength is measured by pulling along one axis (tensile and tear). Knits have no fixed yarn direction, so a straight pull is misleading; bursting strength applies force in all directions at once. Both are correct for their structure, just not interchangeable.

Do you supply knit fabrics?

No. We are a woven mill and produce woven cloth only. For the woven panels in your garment we can develop and supply directly; for knit parts you would source from a knitting specialist.
