Creating a tech pack for knitwear is a vital phase in transforming an artistic concept into a consistently manufacturable garment

The unique behavior of knitted fabrics, including their give, rebound, and dimensional stability, necessitates precise and tailored technical guidance

A meticulously crafted tech pack acts as the definitive blueprint for manufacturers, ensuring seamless alignment across design, sampling, and production teams

The purpose and target market directly shape material selection, stitch complexity, and construction techniques

Your target demographic will influence everything from yarn weight to finishing details

Include precise flat sketches from all critical angles: front, back, side, and optional detail views

These illustrations must clearly indicate seam placements, hem finishes, neckline shapes, and decorative motifs like cables, lace, or Fair Isle patterns

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

Example: 65% cashmere, 35% silk, 180g per hank, 2-ply

Always reference the vendor or mill to ensure consistency across production runs

The integrity of the final garment depends heavily on yarn consistency; small deviations can lead to fit failures

Indicate the machine model and needle gauge, as they directly affect texture, warmth, and drape

Include needle count and bed configuration when relevant to the design

Clearly define the start and end points of each pattern repeat with precise measurements

Accurate flat measurements are mandatory to ensure proper fit across sizes and factories

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

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

In Women's Knitwear, even a 0.5 cm difference can significantly alter fit, comfort, and perception of quality

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

Define where each label must be sewn: neck seam, side seam, or inner hem

Mention special packaging requirements: tissue paper, polybags, hangtags, or anti-snag guards

Add quality control benchmarks: acceptable levels of pilling, shrinkage, color fading, or dimensional change

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

A flawless tech pack removes guesswork, reduces sampling cycles, and ensures factory compliance

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

Knitwear looks simple, but one missed detail can ruin the entire run
