A well-structured tech pack is the foundation for accurately producing knitwear that meets design intent and production standards

Knitwear’s inherent flexibility, elasticity, and texture require more nuanced specifications than traditional woven materials

A comprehensive tech pack bridges the gap between concept and reality, aligning all stakeholders on fit, finish, and function

First, define the garment’s role: is it casual streetwear, activewear, or high-end fashion?

This determination will guide choices in fiber blends, stitch profiles, and assembly methods

Ensure your drawings include front, back, and side views with labeled construction elements

Each sketch should meticulously show stitch lines, edge treatments, and any ornamental knitting techniques

Material specifications are non-negotiable—list the exact yarn composition, including fiber percentages, weight per skein, and thickness

30% nylon blend at 220g per skein

Whenever possible, name the yarn brand and approved supplier

Knitwear performance hinges on yarn behavior—even minor shifts in fiber type or ply can dramatically impact drape, stretch, and hand feel

Specify the knitting machine type and its gauge—5-gauge yields a loose, open knit, while 12-gauge creates a tight, dense fabric

Note the number of needles per inch and whether it’s a single or double bed machine

If your design incorporates varied stitch patterns—ribbing, jacquard, Fair Isle, or intarsia—mark exactly where each begins and ends, using centimeters or inches

Always include a measurement table with all key dimensions: bust, waist, hip, armhole depth, and total length

Indicate clearly: "Measurements taken flat, un-stretched" or "Measured with 10% stretch applied"

Specify allowable tolerances—e.g., ±0.5 cm for key areas

A half-centimeter shift in shoulder width can make a Women's sweater manufacturer feel too tight or too loose

Specify joining techniques to ensure durability and aesthetic consistency

Define seam finishes with intent: "Flatlock for minimal bulk," "Coverstitch for clean edge," "Hand-sewn for luxury detail"

Detail all edge treatments: double-fold hems, picot edges, elasticized bands, or tubular finishes

Label placement is critical—specify exact locations for care labels, size tags, and brand logos

Protect knitwear from snags—specify packaging materials that prevent abrasion and deformation

Set measurable QC standards to ensure consistency across batches

Reference relevant industry standards like ASTM, ISO, or AATCC where applicable

A robust tech pack eliminates ambiguity, prevents misinterpretation, and minimizes costly production errors

Invest time reviewing your tech pack with a sample maker, pattern engineer, or production specialist before factory submission

A single review session now can eliminate dozens of revisions down the line

Remember: knitwear design is forgiving, but knitwear execution is merciless—clarity and precision are your only allies
