SEWING LINES — PARTNER FACTORY, SOUTHEAST CHINA
Partner Factories
One specialty, done well: knit underwear.
The partner factories we work with in south-east China — across the Xiamen, Quanzhou and Jinjiang knitwear cluster of Fujian Province — are purpose-built for knitted underwear and sleepwear — flatlock, coverstitch and bartack stations organized in modular lines that switch between boxer briefs in the morning and pajama sets in the afternoon.
Modular lines mean we absorb both a 2,000-piece first order and a 100,000-piece program without treating either as an inconvenience.
| Specialty | Knitted underwear, sport bras, sleepwear |
|---|---|
| Key machines | Flatlock, coverstitch, 4-needle-6-thread, bartack, elastic attaching, heat-transfer |

SAMPLE ROOM — KNITS, COLORS & PRINTS ON REVIEW
Materials Library
Certified fabrics, tested before they touch a needle.
Every fabric lot we source is certified to OEKO-TEX® Standard 100 and lab-tested for shrinkage, spirality, colorfastness to washing and perspiration, pilling and stretch recovery. Test reports attach to your order file.
Sourcing something unusual — organic cotton, GRS recycled poly, Tencel™ blends? Our fabric team develops custom knits with partner mills in Fujian and Guangdong. Our own merchandisers and QC staff work from a liaison office inside the Jinjiang factory district, staffed since 2013, so each order is followed on the line in Jinjiang and Quanzhou rather than from a desk in another province.

How an OEM/ODM order runs — from design to delivery
At Unitex, we manage the entire underwear production lifecycle. Working with long-term partner factories in Fujian, every step is quality-controlled and documented. BSCI, OEKO-TEX Standard 100 compliant materials, partner factories BSCI-audited.
Step 1: Design & Sampling (7–10 Days)
Share your design ideas, tech pack, or reference sample. Our design team creates lab dips, printing proofs, accessories samples, and fitting samples within 7–10 days.
Step 2: Material Sourcing & Inspection
We source OEKO-TEX Standard 100 certified fabrics: Cotton Jersey, Cotton/Elastane Jersey, Cotton Rib, Modal, Viscose, and Polyester Knitting. Every fabric batch is inspected before production.
Step 3: Bulk Production
Production stages managed through our partner factories:
| Machine Type | Quantity | Function |
|---|---|---|
| Overlock | 30 | Seam construction |
| 4-Thread | 40 | Durable assembly |
| Cover Stitch | 20 | Hem finishing |
| Single Needle | 18 | Precision stitching |
| Double Needle | 18 | Reinforced seams |
| Piping | 12 | Edge binding |
| Waist Elastic | 4 | Waistband attachment |
Step 4: Quality Control & Inspection
15-person Inspection Department conducts quality checks at every stage. 6-person Finishing Department handles trimming, ironing, and presentation. Needle monitoring and metal detection on all garments.
Step 5: Packaging & Global Delivery
25-person Packing Department handles retail-ready packaging. Shipments depart from Xiamen Port with full documentation.
Monthly Production Capacity
Across our partner network, monthly capacity is around 600,000 pieces — one shared pool that is flexed between partner factories, not a fixed ceiling per category. Capacity is allocated per order, so the number that matters is the slot we can hold for your style and ship window: send us the style, quantity and delivery window and we will confirm it. The network covers men’s boxer briefs, briefs and trunks, women’s briefs, bikinis and hipsters, kids’ briefs, and pyjama sets.

Minimum order quantities
MOQ exists because every new style carries a fixed set-up cost — dyeing minimums, cutting changeover, line set-up and a pre-production sample. Production starts at the standard minimum set out below, and bulk pricing is agreed up front.
| Category | Standard MOQ | Sampling lead time |
|---|---|---|
| Men’s underwear (boxer briefs, briefs, trunks) | 2,000 pcs per style / colour | 7–10 days |
| Women’s underwear (bikinis, hipsters, thongs) | 2,000 pcs per style / colour | 7–10 days |
| Kids’ underwear | 3,600 pcs per style / colour | 7–10 days |
| Sleepwear & pyjama sets | 600 sets per style | 12–18 days |
| Sport bras | 3,600 pcs per style | 12–18 days |
From enquiry to delivery
| Stage | Duration | What happens / what you receive |
|---|---|---|
| Enquiry & costed quotation | within 48 hours | Cost breakdown, fabric options, MOQ position, indicative lead time |
| Lab dip & fabric approval | 3–7 days | Colour swatches for approval under D65 light |
| Fit / development sample | 7–10 days | Sample with comments sheet; one revision round included |
| Pre-production sample (PPS) | 5–7 days after bulk fabric arrives | Sealed sample, labels, packaging — approved in writing before bulk |
| Bulk production | 45–60 days | Inline inspection reports; weekly progress updates |
| Pre-shipment inspection | a few days before dispatch | AQL 2.5 report, measurements, packing check |
| Sea freight to EU/UK | 25–40 days port-to-port | Booking, documents, tracking |
Plan backwards from your launch date. Chinese New Year adds 2–3 weeks of closure, so for goods in your warehouse by 1 March, place the purchase order by mid-December and start sampling in late November. Quotations are valid for 30 days.
Repeat orders typically run faster than new styles once the blocks and fabrics are approved; new-style programmes need the full window because fabric development and fit rounds come first.
Quality control at each stage
- Before bulk: fabric inspection (weight, shrinkage, colour continuity) and PPS approval.
- During bulk: inline checks at cutting, sewing and finishing; first-off approval on each line.
- Before shipment: AQL 2.5 inspection — quantity, workmanship, measurements, packing, barcode scan test.
- Testing: composition, colourfastness, dimensional stability, pilling and market-specific tests through third-party labs.

| Supplier | Unitex Underwear (Xiamen Unitex Trade Co., Ltd.) — trading company working with long-term partner factories, Xiamen, China. |
|---|---|
| Stage 1 — Design and sampling | Counter samples 7–10 days where fabric and trims are in stock; fully custom development 12–18 days counted from colour confirmation |
| Stage 2 — Material sourcing and inspection | Fabric and trims sourced, then tested before cutting: shrinkage, colourfastness, GSM and composition checked against the approved specification |
| Stage 3 — Bulk production | 45–60 days after pre-production sample approval and deposit; repeats from stock fabric run 30–40 days |
| Stage 4 — Quality control and inspection | In-line checks during production, then final inspection at AQL 2.5, Level II, measured against the sealed golden sample |
| Stage 5 — Packaging and delivery | Packing to the agreed specification, pre-shipment photographs, then shipping documents issued for the destination market |
| Golden sample | A reference unit signed off by both sides before bulk; every later inspection measures against it |
| Defect thresholds at AQL 2.5 | Zero critical defects; major defects ≤2.5%; minor defects ≤4.0% |
| Compliance | OEKO-TEX Standard 100 certified fabrics; amfori BSCI audit position at the production site |
| Trade term | FOB Xiamen; quotations valid 30 days |
| Inline checkpoints | First-off approval at cutting, sewing and finishing, then in-line checks at every operation while the goods are still correctable on the line |
Buyer checklist
- Ask which factory your order will run in, and treat the answer as part of the quotation rather than as an afterthought.
- Request that the golden sample be sealed and signed before bulk begins, because it is the reference every later inspection measures against.
- Confirm the inspection standard and the sampling level in writing: AQL 2.5, Level II, with zero critical defects.
- Put the AQL and the inspection level on the purchase order itself, so the standard the inspection will be measured against is a contract term rather than an assumption.
- Ask for the inline checkpoints and not only the final inspection, since a defect found at the line costs less than one found at the port.
- Request material test reports for the fabric batch before cutting rather than after the goods are finished.
- Agree the packing specification before production, because packing is a factory-stage decision that cannot be corrected at the destination.
- Ask for pre-shipment photographs and the shipping document set to be issued together, so the documents and the goods can be reconciled before departure.
