This guide explains every stage of the OEM T-shirt manufacturing process in Vietnam, from raw fabric to finished export-ready garments.

Why Vietnam is one of the world’s best places for T-Shirt manufacturing

Vietnam is one of the world’s largest exporters of textiles and garments, supplying products to many globally recognized fashion brands. Thousands of factories specialize in knitwear, including T-shirts, polo shirts, hoodies, sportswear, and casual apparel. The country offers an excellent balance of manufacturing quality, cost efficiency, and export experience.

Step 1: product design and technical pack

Every successful OEM garment project begins with a detailed product specification.

A buyer provides either:

• A complete tech pack.
• A reference sample.
• A sketch or design idea.
• Branding requirements.

The factory’s technical team reviews whether the design can be manufactured efficiently and suggests improvements if necessary.

A tech pack usually includes

• T-shirt style and silhouette.
• Fabric composition.
• GSM (fabric weight).
• Size chart.
• Color references (Pantone).
• Stitching details.
• Neck construction.
• Sleeve style.
• Labels and hangtags.
• Packaging instructions.

This stage is essential for OEM T-shirt manufacturing in Vietnam because it becomes the production blueprint.

Step 2: fabric selection and sourcing

Fabric is the most important factor affecting the look, comfort, durability, and price of a T-shirt.

Vietnamese garment manufacturers source fabrics locally and internationally depending on customer requirements.

Step 3: knitting the fabric

Unlike woven shirts, T-shirts are made from knitted fabric.

Most factories receive knitted fabric from specialized textile mills, although integrated manufacturers knit fabric in-house.

Common knit constructions

• Single Jersey.
• Rib Knit.
• Interlock.
• French Terry.
• Piqué (for polo shirts).

Knitting machines create continuous tubular fabric that later becomes garment panels.

Step 4: dyeing and fabric finishing

After knitting, fabric is dyed according to the customer’s Pantone color.

Finishing treatments may include

• Reactive dyeing.
• Enzyme wash.
• Silicone softening.
• Anti-pilling treatment.
• Moisture-wicking finish.
• UV protection.
• Anti-bacterial finish.

Factories also test:

• Color fastness.
• Shrinkage.
• Fabric width.
• Fabric weight.
• Surface defects.

Step 5: fabric inspection

Before cutting, every fabric roll is inspected.

Quality inspectors check

• Holes.
• Oil stains.
• Color variation.
• Yarn defects.
• Width consistency.
• Printing defects (if pre-printed).

Defective fabric is removed before production begins.

Step 6: pattern making and marker planning

Professional pattern makers convert the design into production patterns.

They create

• Front panel.
• Back panel.
• Sleeves.
• Neck rib.
• Pocket pattern (if required).

Marker software arranges patterns to maximize fabric usage and reduce waste.

Step 7: automatic fabric spreading and cutting

This is where production becomes highly automated.

The cutting process

1. Fabric layers are spread automatically.
2. Layers are aligned precisely.
3. Computer-controlled cutters cut hundreds of garment pieces simultaneously.
4. Pieces are bundled by size and color.

Modern Vietnamese factories use CNC cutting machines for precision and speed.

Why automatic cutting matters

• Better consistency.
• Lower fabric waste.
• Faster production.
• Accurate sizing.

Step 8: logo printing or embroidery

Branding is applied before or after sewing depending on the design.

Factories test print durability through washing and rubbing tests.

Step 9: sewing the T-shirt

The sewing line is where dozens of individual components become a finished garment.

Machines commonly used

• Overlock.
• Flatlock.
• Coverstitch.
• Lockstitch.
• Bartack.

Each sewing operator performs a specialized task on an assembly line.

Step 10: in-line quality control during sewing

Quality control does not happen only at the end.

Inspectors continuously monitor:

• Stitch density.
• Seam alignment.
• Thread tension.
• Needle damage.
• Fabric stains.
• Size measurements.

Problems are corrected immediately before garments continue down the production line.

Step 11: washing, steaming, and finishing

Many premium T-shirts undergo garment washing after sewing.

Popular finishing treatments

• Enzyme wash.
• Vintage wash.
• Acid wash.
• Pigment wash.
• Stone wash.
• Silicone softening.

After washing, garments are:

• Steam pressed.
• Thread trimmed.
• Shape checked.
• Folded.

Step 12: labels, hang tags, and private label branding

OEM manufacturing means the garment carries your brand, not the factory’s brand.

Factories attach:

• Neck labels.
• Size labels.
• Care labels.
• Woven labels.
• Printed labels.
• Hang tags.
• QR code labels.
• Sustainability labels.

This is essential for private label T-shirt manufacturing in Vietnam.

Step 13: final inspection (AQL quality control)

Before packing, factories perform a final inspection.

AQL inspection checks

• Measurements.
• Stitch quality.
• Printing placement.
• Embroidery quality.
• Color consistency.
• Packaging accuracy.
• Label correctness.

Many export factories follow internationally recognized AQL inspection procedures before shipment.

Step 14: folding, packaging, and carton packing

Packaging is customized according to buyer requirements.

Packaging options include

• Individual polybags.
• Recycled polybags.
• Paper packaging.
• Size stickers.
• Barcode stickers.
• Carton labels.
• Mixed-size cartons.
• Retail-ready packaging.

Factories follow customer carton specifications for Amazon FBA, retail chains, wholesalers, or distributors.

Step 15: export logistics from Vietnam

Finished garments are shipped worldwide.

Factories prepare export documentation, including commercial invoices, packing lists, certificates of origin when required, and shipping documents.
