Polo Shirt Manufacturing Process, Step by Step

1. Spec, tech pack and quotation

Production starts with paperwork, not machines: composition, GSM, colors, size chart, decoration positions, trims and packaging are fixed in the tech pack and quoted item by item. Ambiguity here becomes rework later, so this stage ends with a written specification both sides reference.

2. Fabric sourcing and lab dips

Knit fabric is ordered from qualified mills or produced to spec. Custom colors go through lab dips: small dye samples submitted against your Pantone or physical standard until one is approved. The approved dip is the shade reference for the bulk fabric lot.

3. Pattern, grading and markers

The base-size pattern is made or adjusted from your block, then graded across the size set. Markers — the nesting of all pattern pieces across fabric width — are created to control waste, with special handling for stripes, directionality and knit grain.

4. Cutting and panel preparation

Relaxed fabric is spread in layers and cut against the marker. Panels are bundled by size, color and shade so pieces that should match stay together. Collar and placket panels — the signature elements of a polo — are cut and prepared separately.

5. Decoration on panels

Embroidery, screen printing, heat transfer and patches are applied to flat panels: chest logos, sleeve marks and back-neck branding. Flat decoration avoids distortion and keeps registration precise; a test sew-out is approved before multi-head production.

6. Sewing assembly

Assembly follows the logical build of the garment: collar construction and attachment, placket, shoulders, sleeves, side seams, hemming and cuffs, with label insertion at the assigned operation. Inline checkers verify workmanship at the operations most likely to create defects.

7. Trimming, pressing and measurement audit

Threads are trimmed, garments checked for stains and pressing marks, then pressed. A first measurement audit compares finished garments against the approved spec chart before units move toward packing.

8. Final AQL inspection

Finished units are sampled statistically (typically AQL 2.5 major / 4.0 minor unless your standard differs) for workmanship, measurement and packing compliance. Results and photographs are shared before balance payment; failed lots are sorted, repaired or re-made.

9. Packing, documentation and handover

Approved goods are folded or hung, polybagged with required warnings, tagged, cartoned to the assortment list, sealed and marked. Invoice, packing list and required certificates are prepared, and cargo is handed to the named forwarder under the agreed trade term.
