Embroidery
Computerised, sequin and appliqué embroidery.
What really happens at this stage
Computerised embroidery stitches digitised designs onto garment panels using multi-head machines that follow a punched stitch file controlling needle position, stitch density, and thread colour changes. The digitising step converts artwork into a stitch path, setting underlay stitches that stabilise the fabric before the top design stitches are laid down, which prevents puckering on lightweight or stretch fabrics. Backing or stabiliser material is hooped or tacked under the fabric to hold it flat during stitching and is trimmed away afterward. Thread tension, needle size, and machine speed are tuned to the fabric weight and design density, since dense fills on thin fabric without adequate stabiliser commonly cause show-through or fabric distortion.
Beyond standard thread embroidery, sequin and applique attachments extend the technique using dedicated machine devices that feed sequin tape or place fabric patches during the stitch cycle, adding texture and dimension the flat stitch cannot achieve alone. These attachments require careful timing calibration so the sequin or applique lands precisely within the stitch sequence without jamming the head. Quality checks focus on stitch registration matching the artwork, thread breaks, and puckering, with hooping accuracy being the most common source of design placement error relative to garment landmarks such as the chest point or pocket edge.
How it is done
- 1Digitise the design
Convert artwork into a stitch file, setting underlay, stitch density, and colour sequence appropriate to the fabric.
- 2Select stabiliser
Choose backing weight matched to fabric type and stitch density to prevent puckering or show-through.
- 3Hoop the garment accurately
Position and tension the panel in the hoop so the design lands correctly relative to garment landmarks like the chest point.
- 4Set machine parameters
Tune thread tension, needle size, and stitching speed for the fabric weight and design complexity.
- 5Run and monitor the stitch cycle
Watch for thread breaks, colour change accuracy, and sequin or applique feed timing during the run.
- 6Trim and inspect
Remove excess stabiliser and jump stitches, then inspect placement, density, and puckering against the approved sample.
Key metrics (indicative targets)
| Metric | Working target | Why it matters |
|---|---|---|
| Design placement accuracy | Within a few millimetres of the approved sample | Off-placement designs look wrong relative to garment seams and pockets, causing rejects. |
| Thread break rate | Low breaks per thousand stitches, indicative | Frequent breaks slow throughput and risk inconsistent stitch density at the repair point. |
| Puckering incidence | Under 2% of pieces, indicative | Excess puckering from wrong stabiliser choice is a common cause of rejection. |
| Sequin/applique attachment success | High first-pass success rate | Feed jams or misplacement on decorative attachments require costly manual rework. |
| Machine head utilisation | High run-time share against planned capacity | Idle heads from thread breaks or hooping delays reduce embroidery unit output. |
Targets are indicative working ranges, not standard or legal limits.
Control points to check and sign off
- Stitch file approved against the physical sample before production run
- Stabiliser type and weight matched to fabric and confirmed before hooping
- Hooping alignment checked against garment landmarks before each batch
- Thread tension and machine speed verified on a test piece before full run
- Finished pieces inspected for placement, density, and puckering before passing to next process
Common pitfalls and their consequences
- Using an undersized stabiliser for dense designs, causing puckering that is hard to press out
- Inaccurate hooping, resulting in designs sitting off-centre relative to the chest point or pocket
- Ignoring thread tension drift over long runs, producing loose or tight stitches mid-batch
- Poor timing calibration on sequin attachments, leading to jams and stopped machine heads
- Skipping the physical sample check before bulk run, letting a digitising error reach full production
