Manufacturing Process Deep Dive: From Fabric to Finished Garment
Understanding key factory-floor operations helps you appreciate supplier strengths—and spot warning signs of poor manufacturing.
Fabric Sourcing & Inspection
Bulk fabric arrives and is inspected using the 4-point system. Lab dips are created for color matches, and chemical/physical tests confirm fiber composition, GSM, and finishing properties.
Cutting & Spreading
Fabric relaxes for 24–48 hours to stabilize. Spreading crew lays fabric to the required ply count, followed by cutting via straight knife, band knife, or automated cutter.
Sewing Line Setup and QC
Operation breakdown assigns SMV for each sewing step. Key seams use lockstitch (ISO 301), chainstitch (401), or overlock (504/514) based on the garment type. Inline QC checks stitch density, thread tension, and label placement.
Finishing and Packing
- Garments undergo washing (enzyme, normal wash, or silicone softener).
- Final trimming, pressing, folding, and packaging per spec.
- Metal detection for children’s wear or export goods.
Measurement & Performance Testing
Random samples from bulk are washed, measured, and checked for colorfastness, shrinkage, pilling, seam integrity, and size specs.
Packing Methods Table
| Packing Type | Bag Spec | Carton Spec | Best Use |
|---|---|---|---|
| Single Polybag | 30–50 micron PE, vent holes | 5-ply, 1200–2400g | Retail, export |
| Size Ratio Pack | Marked per size, grouped by color | Printed size marking | Bulk, wholesale |
| No Poly (Bulk Fold) | Direct carton, folded stacks | Plain or marked, inner paper | Low-cost, local |
Garment Categories: What to Ask for Different Products
Each category poses distinct requirements in material selection, construction, and QC. Tailoring your factory search to the garment type ensures better results.
T-Shirts & Polo Shirts
- Single jersey, pique knit, rib trims. Ask about shrinkage allowance, neck tape attachment, placket construction.
Hoodies & Sweatshirts
- Fleece, French terry, elastic rib cuffs, metal eyelets. Review methods for hood construction and pocket stitching.
Shorts & Sportswear
- Polyester mesh, nylon blends, drawcords, elastic waistbands. Confirm stretch/recovery, seam slippage, and print wash resistance.
Workwear & Uniforms
- Heavy cotton twill, denim, reinforced seams, safety trims. Ask about industrial wash durability and badge/patch attachment.
Rain’s Tip for Category Sourcing
“Insist on category experience. A factory skilled in sportswear construction will build more durable shorts than a generic basic tee supplier.”
Quality Control and Performance Testing Essentials

Quality assurance isn’t a single inspection—it’s a continuous process. Buyers should implement multi-stage testing to minimize risk and guarantee performance.
Pre-Production
- Lab test fabric for GSM, fiber content, colorfastness, and finishing agents.
- Inspect PP samples for stitch types, trims, label position, and measurements.
Bulk Production
- Inline QC checks for SPI, seam slip, skipped stitches, and matching trims.
- End-line QC: Random garment checks for measurement tolerance, finishing, and packing compliance.
Performance Testing
- Shrinkage, pilling, wash fastness, and seam burst strength.
- Special testing: nickel-free trims for children’s wear, chemical safety in accordance with OEKO-TEX® or REACH standards.
