A knitwear tech pack is the working specification that connects a design idea to sampling and bulk production. It should show the style from front and back, define measurements and fit, describe yarn and knit construction, identify colours, artwork, trims, labels and packing, and carry a clear revision number. It does not need to answer every technical question before the first review, but it must separate confirmed requirements from open decisions.
What a usable knitwear tech pack should do
- Give one style a unique style number and revision date.
- Show design details that cannot be understood from one front image.
- Define the base size, points of measure and intended fit.
- State what is confirmed and what the factory should recommend.
- Keep sampling comments and bulk requirements traceable.
The nine essential sections of a knitwear tech pack
| Section | What to include | Why it matters |
|---|---|---|
| 1. Cover page | Brand, style name and number, season, date and revision | Prevents different files from being treated as the same version |
| 2. Flat sketches | Front, back and detail views with callouts | Shows proportions and construction intent |
| 3. Measurement chart | Base size, points of measure, units and size range | Creates a measurable fit reference |
| 4. Yarn and colour | Fibre direction, yarn reference, colour standard and handfeel | Guides sourcing and sample development |
| 5. Knit construction | Stitch structure, ribs, panels, pattern placement and technique | Connects the visual design to manufacturable knitting instructions |
| 6. Artwork | Jacquard, intarsia, embroidery or print files, size and placement | Reduces interpretation of scale and position |
| 7. Trims and labels | Buttons, zips, patches, labels, hangtags and placement | Allows accurate development and sourcing |
| 8. Finishing and packing | Wash/finish direction, folding, bags, cartons and special presentation | Clarifies the product condition expected at delivery |
| 9. Buyer requirements | Destination market, testing, documentation and inspection requirements | Separates buyer-specific obligations from standard production |
These sections can be separate pages or grouped into a shorter document. The best format is the one your product team can maintain accurately. A ten-page file with outdated information is less useful than a concise, controlled specification. Once the file is ready, review the knitwear sampling process so your team knows how each decision will be tested.
What makes a knitwear tech pack different?
Knitwear is formed from yarn and stitch structures rather than cut entirely from pre-existing fabric. A small change in yarn, tension, stitch or finishing can affect weight, stretch, recovery, measurements and appearance at the same time. That is why a generic apparel sketch is not enough for many sweater styles.
Your document should identify details such as body and sleeve structure, rib depth, neckline construction, fully fashioned shaping, panel direction, pattern placement and any engineered artwork. If you do not know the technical name, use a clear close-up image and mark the exact area you want the factory to evaluate.
Do not guess a machine gauge or yarn count simply to fill an empty field. State the target look, weight and handfeel, then mark the technical specification as “factory to recommend” if it still needs development. This is clearer than presenting an unverified number as fixed.
How to build the measurement page
Choose one base size for the first fit sample and give every point of measure a code. Each code should match a small diagram showing exactly where and how the measurement is taken. State whether measurements are taken flat, relaxed, stretched or after a specified treatment.
- Use one measurement unit consistently.
- Include chest, body length, shoulder or cross-back, sleeve length, armhole, neckline and opening measurements that are relevant to the style.
- Define rib and trim dimensions where they affect fit.
- Add size grading only when your team has approved the intended size range.
- Record tolerances if your buyer has defined them; do not copy a generic tolerance without review.
Measurement numbers and the fit description must agree. If the style is intended to be oversized, explain the ease and silhouette instead of relying only on a larger chest measurement.
How to specify yarn, colour and construction
If you have an approved yarn, provide the supplier or reference, fibre composition, yarn count, colour code and any required evidence. If you only have a direction, describe the commercial target: soft and lightweight, warm and substantial, smooth, brushed, dry, structured, easy-care or premium natural handfeel.
Cotton, polyester, wool, cashmere and common blends can be evaluated by Rishi Apparel, subject to the design and commercial requirements. Actual availability must be confirmed for the project.
For colour, use a physical or recognised digital reference when possible. Screen colours alone can vary between devices. State whether different components—body yarn, rib, embroidery, zipper tape or buttons—must match exactly or follow separate references.
Artwork, trims, labels and packaging
Place every artwork file next to a dimensioned placement diagram. Identify the technique—such as jacquard, intarsia or embroidery—only when confirmed, and provide an editable artwork file where possible. Note whether placement should be centred on the garment, aligned to a seam or positioned from a specific measurement point.
Create a bill of materials for buttons, zippers, labels, hangtags and packaging. For each item, include description, colour, size, supplier reference if nominated, position and approval status. Custom trims can have their own minimum quantities and lead times, so include them in the first quotation review.
State destination-market and buyer requirements separately. Fibre labels, care instructions, chemical testing, children’s requirements and retailer packing rules depend on the product and market. The buyer or importer should define which standards and documents apply rather than assuming they are included automatically.
Use version control for every sample round
Put the revision number and date on the cover and, ideally, in the footer of every page. When comments are issued, create a new version and highlight changed fields. Do not send several attachments with the same filename and ask the factory to decide which one is current.
- Review the sample against the current tech pack.
- Write each comment beside a photo, measurement or specification.
- State whether the change applies to the next sample or to bulk production.
- Update the master measurement chart and bill of materials.
- Mark the superseded version as obsolete and keep it for traceability.
Expressions such as “make it better” or “same as last time” are difficult to control. A useful comment says what is wrong, where it occurs, the expected result and how approval will be judged.
Common knitwear tech pack mistakes
| Mistake | Production risk | Better approach |
|---|---|---|
| Only one front image | Back, inside and construction details are interpreted | Add back view and enlarged detail callouts |
| No revision date | Old comments may be used | Use a controlled filename, version and date |
| “Standard size” | Fit expectations are undefined | Supply base-size measurements and fit direction |
| Unverified technical numbers | The factory may follow the wrong yarn or construction | Mark open fields for technical recommendation |
| Artwork without dimensions | Scale and placement vary | Add size, position and colour references |
| Requirements hidden in emails | Important details may not reach production | Move approved decisions into the current tech pack |
Can you start without a complete tech pack?
Yes. Rishi Apparel can review an authorised physical sample, reference images, sketch or early product idea. The first stage will identify missing decisions and determine whether the project needs an OEM-led route, more ODM development support, or a hybrid process.
A reference does not remove the need for specifications. Measurements, yarn, colour, branding, labels, packing and approval criteria still need to be recorded before bulk production. Buyers are responsible for having the right to use any supplied design, sample or artwork.
Before contacting the factory, use our custom knitwear quote checklist. You can also compare OEM and ODM development, review the production process, and understand what affects MOQ.
Frequently asked questions
What file format should a tech pack use?
A PDF is useful as the controlled issue file, while an editable spreadsheet or design file can support measurements, artwork and revisions. Make sure every format carries the same version number.
Do I need to specify the knitting gauge?
Only if it has been technically confirmed. Otherwise, provide the target appearance, weight, reference and handfeel, then ask the factory to recommend a suitable construction.
Can the factory create measurements from a sample?
An authorised reference sample can be measured as a starting point. The buyer should still confirm the intended base size, fit changes and final measurement chart.
Should prices be written inside the tech pack?
Commercial terms are usually controlled separately. The tech pack should contain the product details needed to make the quotation accurate.
When is the tech pack ready for bulk production?
When the approved sample, measurements, yarn and colour, construction, artwork, trims, labels, finishing, packing and buyer-specific requirements are aligned in the current version. Open points should be closed or explicitly approved before bulk starts.
