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

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

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

Label all structural and decorative features with precision—seams, hems, neck contours, and pattern repeats

Specify every component of the yarn, from natural to synthetic content, with exact weights and thickness metrics

For example: a 70% merino wool

Include the manufacturer’s name and batch reference if available

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

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

If using circular or flatbed machines, specify the configuration and needle arrangement

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

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

Always state whether measurements are taken flat or stretched—knitwear behaves differently under tension

Define acceptable variance: ±3mm for sleeve length, ±5mm for body length

Precision is paramount—knitwear has no forgiving seams; accuracy defines success

Specify joining techniques to ensure durability and aesthetic consistency

Indicate whether seams must be flatlocked for a seamless look or if a specific stitch type is required for strength or visual appeal

Specify all final edge treatments that impact appearance and function

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

Set measurable QC standards to ensure consistency across batches

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

Feedback at this stage can prevent weeks of rework, delays, and wasted materials
