What Is Double Knit Fabric? A Buyer Guide
Double knit fabric is produced with two needle systems, creating interconnected loop structures that often give more body, stability, and surface balance than single jersey. The family includes interlock, Ponte Roma, air-layer, rib-derived, and other double-sided constructions. Buyers should use the family name to shortlist options, then approve the exact construction, composition, GSM, width, finish, recovery, and garment result.

Double knit describes a family, not one fixed fabric
A double-knit machine forms linked structures using two needle beds or cylinders. The resulting fabric can have two usable-looking faces, increased thickness, reduced edge curl, or greater shape stability, although each result depends on the actual structure and yarn setup.
Interlock tends toward smooth balanced faces; Ponte Roma tends toward compact body and controlled give; air-layer structures may create cushioning; jacquard can build pattern into the knit; and rib configurations create vertical texture and extension. These labels help organize sourcing, but they are not substitutes for the article specification.
Double knit versus single jersey in buyer decisions
The common distinction is structural. Single jersey usually has visibly different face and reverse sides and may curl at cut edges, while many double knits are more balanced and substantial. That difference can affect drape, opacity, seam profile, consumption, and the amount of shape a garment holds.
Neither family is automatically higher quality. A light T-shirt may benefit from jersey drape, while a fitted dress or structured jacket may benefit from double-knit body. Compare construction and finish under the real pattern rather than ranking fabrics by thickness alone.
| Decision | Single-knit starting point | Double-knit starting point |
|---|---|---|
| Surface | Often distinct face and reverse | Often more balanced or double-sided |
| Body | Commonly lighter and more fluid | Often fuller and more structured |
| Edges | May curl depending on article | Often more stable, not guaranteed |
| Use | T-shirts and light layers | Dresses, trousers, jackets, structured layers |
Where finished double knit fabric fits
Double knit can support dresses, skirts, trousers, jackets, uniforms, hoodies, sports-inspired pieces, winter layers, loungewear, and statement jacquards. The broad range is why the garment application should appear at the top of the inquiry.
A buyer seeking clean tailoring may prioritize compactness and recovery; a hoodie may prioritize cushioning and seam comfort; a winter layer may prioritize warmth and brushed hand; a patterned piece may prioritize motif scale and reverse appearance.
- Ponte and Roma-style tailoring
- Smooth interlock tops and layers
- Scuba-style hoodies and jackets
- Jacquard fashion programs
- Wool-blend and brushed winter apparel
Specify the double-knit subtype and finished result
Write the subtype, composition, target weight, usable width, face and reverse, finish, color, stretch direction, recovery, thickness and garment use. Do not collapse these fields into a single adjective such as premium, soft, heavy, or stretchy. The supplier and buyer need the same written target and the same labeled physical reference.
For a broad request, ask the supplier to propose two or three constructions and explain the trade-off in body, recovery, surface, care and price. If a requirement is not yet known, mark it as a proposal field instead of leaving it implicit. That allows the supplier to explain the trade-off and prevents an exploratory sample from being mistaken for final approval.
| Specification field | Why it matters | Approval evidence |
|---|---|---|
| Construction | Separates interlock, Ponte, air-layer, rib, jacquard and other double knits | Labeled sample and article sheet |
| Composition | Defines fibre identity, not complete behavior | Written supplier declaration and buyer-required verification |
| GSM and usable width | Affects body, consumption and pattern planning | Agreed method and approved specification |
| Surface and finish | Controls face, reverse, brushing, pattern and tactile direction | Face/reverse review and approved swatch |
| Performance | Covers recovery, growth, seam, pilling, care and garment needs | Garment trial and applicable test plan |
Evaluate structure before approving hand feel
Identify the structure and compare both faces before judging softness. Check whether the sample behaves like the named subtype and whether the supplier sheet matches the cutting.
Then test the fabric in the intended panel. Body, edge stability, seam bulk, stretch and recovery can change how a pattern fits even when the loose swatch looks attractive.
- 1Label the submission with supplier, article, color, date and version.
- 2Inspect face, reverse, edge, weight, width, stretch direction, recovery, thickness and surface consistency.
- 3Record measurements and visible observations against the brief.
- 4Run cutting, sewing, pressing, decoration and care-development checks relevant to the garment on the exact submitted article.
- 5Approve one dated sample and list unresolved tests or commercial terms.
Connect the learning page to a finished-fabric RFQ
O'range Textile's supplied catalogue describes 104 finished-fabric records across 11 series. The parent company's supplied machine record describes 200+ circular knitting machines across double-knit and rib configurations. The same parent-company record includes rounded groups of 60+ 84-feed and 100+ 72-feed double-knit machines, plus 40+ rib machines. These records provide context for development review, but they do not replace article-specific data.
Send the intended garment, construction, composition, target GSM, usable width, color, finish, quantity, destination, sample deadline and testing requirements. Name the desired subtype instead of sending only the phrase double knit fabric. Confirm availability, MOQ, lead time, packing, testing, payment and shipping through the current quotation.
- Name the garment and panel where the fabric will be used.
- Separate fixed requirements from supplier proposal fields.
- Request a labeled finished-fabric sample and matching data sheet.
- State buyer, market and destination requirements before quotation.
- Link final approval to one sample version and written specification.
Evidence boundary
The supplied catalogue supports a finished-fabric range and documents 104 product records across multiple series. Construction names, composition, GSM, usable width, finish, color, testing status, lead time, and commercial terms still have to be confirmed for the exact offered article and order.
Buyer questions
Frequently asked questions
Is double knit fabric always thick?
No. Double knits are often more substantial than comparable single knits, but weight and thickness vary with structure, yarn, gauge, density and finishing. Confirm GSM and the physical sample.
Is Ponte Roma a double knit?
Yes, Ponte Roma is generally part of the double-knit family, but commercial articles vary in composition, compactness, stretch, recovery and surface.
Does double knit fabric curl at the edges?
Many double knits are more edge-stable than single jersey, but behavior is article-specific. Cut and sew the sample rather than relying on the family name.
What garments use double knit fabric?
Common applications include dresses, skirts, trousers, jackets, uniforms, structured tops, hoodies, sports-inspired pieces and winter layers.
What should be included in a double knit RFQ?
Include subtype, composition, GSM, usable width, surface, finish, color, stretch, recovery, garment, quantity, destination, sample deadline and testing needs.
