Finished fabric sourcing route
Interlock Fabric for Stable Apparel Construction
Interlock fabric is a stable double-knit construction with two smooth-looking faces and more body than typical single jersey. O'range Textile can review interlock and adjacent smooth double-knit requirements for finished apparel fabrics. Buyers should confirm the exact construction on the labeled sample because a smooth double-sided surface alone does not prove that every proposed article is true interlock.
What interlock fabric means in a sourcing brief
Interlock uses two connected rib-like systems to create a fabric that commonly presents smooth faces, balanced appearance, and greater stability than many single knits. It is considered for tops, dresses, childrenswear, linings, uniforms, and other programs that need a clean surface with moderate structure.
For sourcing, the category name is only the starting point. Buyers should record the exact construction, fibre composition, target GSM, usable width, surface or brushing treatment, color reference, stretch direction, recovery expectation, and intended garment. Do not treat interlock, Ponte Roma, and generic double knit as interchangeable. They can share a double-knit family while differing in yarn, loop arrangement, elastane, density, weight, surface, and recovery.
Documented range and manufacturing fit
O'range Textile's supplied workbook records an approximate 210-510 GSM and 133-185 cm usable-width span across the entire supplied 104-record finished-fabric catalogue. This is not an interlock-specific range, not a promise of available values, and not an article specification. Buyers still need the current article sheet, labeled sample, and quotation for the precise construction under review.
The parent company's supplied record documents 200+ circular knitting machines across double-knit and rib configurations. This manufacturing context is not an order specification and not interlock-specific capacity. A buyer should use it only as background for development review, then confirm the exact offered article and order terms in current documents.
| Buyer field | What this page establishes | What the quotation must confirm |
|---|---|---|
| Article identity and sample version | This route supports interlock and adjacent smooth double-knit development; category wording does not identify an approved article. | Article code, current article sheet, and approved sample version |
| Construction and composition | A smooth, double-sided appearance does not establish exact construction or fibre content. | Exact construction and fibre composition on the current article sheet |
| GSM | No article-specific weight is published on this page. | Article-specific GSM, tolerance, test method, and point of measurement |
| Usable width | No article-specific width is published on this page. | Article-specific usable width after the agreed conditioning or relaxation method |
| Stretch and recovery | Direction and performance depend on the proposed article and buyer method. | Stretch direction, extension, and recovery or growth criteria with the applicable method |
| Face, reverse and finish | Both sides and the requested finish need sample-level review. | Approved face, reverse, and finish, including any brushing, surface, or hand requirement |
| Colour approval | No stock colour or approval result is represented here. | Colour reference and approval route for the exact offered article |
| Testing and acceptance | Buyer requirements can be included in the inquiry, but this page reports no outcome. | Test methods, reports, and acceptance rules for the order |
| Catalogue-wide reference only | The approximate 210-510 GSM and 133-185 cm usable-width span belongs to the entire supplied 104-record finished-fabric catalogue, not an interlock-specific range and not a promise of available values. | Use the current article sheet, approved sample, and quotation for article-specific values |
Where interlock can fit an apparel range
Interlock is often shortlisted for polished tops, dresses, childrenswear, uniforms, soft structure, linings, and selected sports or loungewear pieces. The correct choice depends on silhouette, climate, layering, seam construction, care route, and the amount of body or recovery the designer needs. A visual match is not enough: sample the fabric in the intended garment or panel.
Prioritize surface clarity and stability for polished garments; prioritize stretch and recovery only when the fibre and construction support them. Compare candidate swatches under the same light and condition, then document why one version was selected. This creates a usable approval trail for the sourcing, development, quality, and production teams.

- Uniform and schoolwear concepts
- Childrenswear and soft layers
- Stable linings or structured panels
- Programs needing a smooth printable surface
How to evaluate an interlock fabric sample
Start with identity. Match the sample label to the article code and supplier sheet, then check the face, reverse, edge, color, width presentation, and several positions across the cutting. For interlock fabric, pay particular attention to construction identity, face-to-face balance, edge behavior, stretch direction, recovery, opacity, and seam response.
Next move from the loose swatch to the buyer's real process. Cut and sew a representative panel, apply the planned decoration if relevant, and review the agreed care-development result. Record measurements and observations by sample version instead of approving a fabric through an untracked message.
- 1Issue a brief that separates fixed requirements from fields the supplier may propose.
- 2Receive a labeled finished-fabric cutting and the matching specification data.
- 3Inspect both faces, loop definition, edge curl, width, weight, extension, recovery and seam appearance.
- 4Run garment, sewing, decoration, and care checks relevant to the program.
- 5Approve one dated version and list any tests or commercial fields still open.
Prepare a commercial RFQ for interlock fabric
A useful RFQ connects the technical choice to the order. Send the garment application, target composition, construction, GSM, usable width, color or lab-dip reference, finish, quantity, color split, destination, sample deadline, and required documentation. Include a reference swatch or image only as context and state which properties must be matched.
Ask whether the proposed article is true interlock or an adjacent double-knit construction and make that answer part of the approved record. MOQ, lead time, color availability, testing, packing, and payment terms are order-specific and should come from the current quotation. The website must not replace that transaction record.
- Exact application and garment panel
- Composition, construction, GSM and usable width
- Surface, brushing, hand feel, stretch and recovery
- Color reference, quantity, color split and destination
- Sample date, testing needs, packing and commercial deadline
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 interlock fabric the same as double knit fabric?
Interlock is a type of double-knit construction, but double knit is the broader family. Ponte Roma, rib-derived structures, air-layer fabrics, and other double-sided knits may differ from true interlock.
Is interlock fabric suitable for printing?
Its smooth surface can be useful for selected print routes, but print compatibility depends on fibre, finish, color, ink system, curing, and buyer requirements. Test the actual article and process.
Can buyers request an interlock fabric sample?
Yes. Buyers can request a finished-fabric sample for evaluation. The request should identify the target construction, composition, GSM, usable width, color, finish, quantity, application, and destination so the supplier can confirm a relevant article.
What should be confirmed before ordering interlock fabric?
Confirm the article code, exact construction, composition, GSM, usable width, face and reverse, color, finish, stretch or recovery requirements, testing, approved sample, quantity, lead time, packing, and commercial terms in writing.
How does interlock differ from cotton jersey and Ponte Roma?
Compare construction identity first: cotton jersey is a single-knit category, while interlock and Ponte Roma are double-knit sourcing directions, but those names alone do not establish the exact loop structure, composition, GSM, usable width, stretch, or recovery of an offered article. Review labeled cuttings and current article sheets side by side, then confirm the selected construction and sample version in the quotation.
Which GSM, usable width and recovery fields should an interlock RFQ include?
State the target GSM and tolerance, usable width after the agreed conditioning or relaxation method, stretch direction and requested extension, and the recovery or growth method and acceptance rule relevant to the garment. Ask the supplier to return article-specific values on the current article sheet, labeled sample, and quotation rather than applying the catalogue-wide span to interlock.
Move from category research to a sample brief
Share the garment use, construction direction, composition, target GSM, usable width, color, finish and tests that matter. The team can then confirm the appropriate article and quotation route.
