Lab Dip Approval Workflow for Garment-Dyed Tee OEM Buyers

# Lab Dip Approval Workflow for Garment-Dyed Tee OEM Buyers

What is a lab dip approval workflow for garment-dyed tees?A **lab dip approval workflow** is the buyer-controlled sequence that freezes shade, wash state, and fabric hand on a production-intent cotton base before bulk garment dyeing. For Weavnora **100% cotton heavyweight or washed T-shirt** programs in the **220300 GSM** window—and related hoodie/casualwearapprove lab dips after details are confirmed (**about 7 days** for sample), against a **1,000-piece style MOQ**, so the later **about 30-day** bulk plan (project-dependent) matches the signed shade standard for NA and EU shipments.

How should buyers prepare the lab dip package?

Lock these inputs before requesting lab dips:

1. **Target shade** — Pantone / physical standard / approved bulk reference with lighting notes.

2. **Fabric base** — 100% cotton and named GSM inside 220–300, yarn/hand notes if critical.

3. **Wash / finish state** for washed or garment-dyed programs (same state that will ship).4. **Tolerance** — buyer-accepted ΔE or visual pass/fail under agreed light.

5. **Dip count** — how many candidate dips and which side is commercial.

6. **Approve / revise / reject** form with signed comments and date.

When should buyers approve lab dips relative to wash and decoration?Approve shade on the **same wash and finish state** that will ship. If decoration (screen print, DTG, embroidery, or special print) must match a washed ground, keep the approved lab dip with the strike-off package. Changing wash chemistry after shade approval usually requires new dips.

“Approve garment-dye shade on the production substrate and finish state under agreed viewing light before releasing bulk dyeing—visual or instrumental pass criteria should be written on the dip sheet.” — common buyer QA practice aligned with ASTM shade-evaluation norms and AQL final inspection planning

How does lab dip approval connect to sample and bulk release?

• Do not start bulk garment dyeing until the lab dip is **approved in writing**.

• Keep approved dips with the tech pack, PPS, and (when used) strike-off records.

• If GSM target, wash recipe, or shade standard changes, re-run dips before the 1,000-piece style MOQ release.

• Plan bulk timing (~30 days, project-dependent) only after sample confirmation and shade approval.

What should the RFQ say about lab dip approval?State target shade standard, GSM (220–300), wash/finish state, destination (NA/EU), assortment against the 1,000-piece MOQ, decoration method if shade must precede print, and that bulk dyeing starts after signed lab dip.

FAQ

What is a lab dip in garment-dyed tee OEM?A lab dip is a small dyed sample on the agreed cotton base used to approve shade and finish before bulk garment dyeing. It is not a digital mockup or a dip on unrelated fabric.

When should buyers approve lab dips relative to wash?

Approve on the washed or finished state that will ship. For washed T-shirt programs, confirm whether shade is judged after the commercial wash and record that on the dip sheet.

How do MOQ and timing connect to lab dip approval?Style MOQ is 1,000 pieces with mixed colors and sizes supported. Plan about 7 days for sample development after confirmation and about 30 days for bulk, project-dependent. Bulk dyeing should not start until the lab dip is signed.

Who receives the signed lab dip comments?

Send approve / revise / reject notes to postmaster@weavnora.com with style reference, GSM, shade standard, wash state, and size/color mix.

Lab dip options and approval trade-offs

Compare a production-fabric lab dip with a digital mockup or a dip on unrelated fabric: the production-fabric dip gives the buyer the reliable shade, hand, and wash-state result needed for bulk approval. Compare washed versus unwashed samples and use the exact ship state; visual pass/fail under agreed light is practical, while instrumental ΔE adds measurable control. Choose the signed production-state dip before releasing dyeing.
