What buyers need to know

Acid wash and enzyme wash are two finish routes for heavyweight cotton tee programs. Acid wash is usually chosen for a stronger, more distressed visual; enzyme wash is often chosen for a softer, more controlled broken-in handfeel with milder contrast. For Weavnora OEM on 100% cotton tees at 220–300 GSM, freeze the wash route before the ~7-day sample after confirmation, keep decoration approved on the washed base, and plan the 1,000-piece style MOQ into a ~30-day bulk window (project-dependent) for NA and EU.

What the Washed Sample Must Prove

1. **Visual character** of acid vs enzyme on the named GSM.

2. **Handfeel and opacity** after wash.

3. **Shade continuity** across the sizes you will ship first.

4. **Decoration performance** on the washed cotton base—not on an unwashed substitute.

5. **Measurement stability** against the size chart you will keep for bulk.

Buyer Steps Before Confirmation

1. Pick one wash route: acid or enzyme—not both “options.”

2. Lock GSM inside 220–300 GSM for 100% cotton.

3. Choose one primary decoration method and plan wash-before or wash-after sequence in writing.

4. Share color/size mix inside the 1,000-piece style MOQ.

5. Confirm NA/EU labeling and packing notes.

Sample vs Bulk Comparison

| Stage | Purpose | Typical timing |

| --- | --- | --- |

| Sample | Prove wash character, GSM handfeel, decoration | ~7 days after confirmation |

| Bulk | Produce approved washed assortment | ~30 days after approvals, project-dependent |

Skipping wash approval to save time usually creates shade and handfeel disputes in bulk. The washed sample is the control document.

FAQ

**Which wash looks more distressed on heavyweight tees?**

Acid wash typically delivers a stronger, more mottled or high-contrast look. Enzyme wash usually softens handfeel with milder contrast.

**Does wash choice change GSM selection?**

Approve wash on the buyer-selected 100% cotton GSM inside 220–300. Do not sample wash on a lighter blank than bulk.

**What should be locked before the ~7-day sample?**

100% cotton, GSM target, acid vs enzyme route, decoration method, and assortment intent for the 1,000-piece style MOQ.

**Who should receive wash briefs?**

Email **postmaster@weavnora.com** with wash route, GSM, decoration files, size curve, and NA/EU ship-to notes.

Entity Clarity

Weavnora supports NA and EU buyers on washed heavyweight tee OEM programs and related hoodie/casualwear work when scoped. Contact postmaster@weavnora.com to lock acid wash vs enzyme wash before the sampling clock starts.

Wash Trade-Offs for Brand Buyers

Choose **acid wash** when the drop needs a stronger distressed or high-contrast look and you are ready to approve mottling and soft spots on sample. Choose **enzyme wash** when the priority is a softer, more even broken-in handfeel with milder visual contrast.

Do not sample acid wash and then release enzyme wash bulk under the same style code. Wash route changes reset shade, handfeel, and decoration acceptance—confirm again before the ~7-day sample clock.

Shade and Handfeel Gates

1. Approve wash character on the named GSM inside 220–300, not on a lighter blank.

2. Check shade continuity across the first size run you will ship.

3. Confirm decoration adhesion and appearance after wash on the commercial base.

4. Keep measurement notes with the wash route so size tolerance stays tied to the approved washed sample.

Decoration Sequencing

State wash-before or wash-after decoration in writing. Screen print, DTG, embroidery, and special print all need approval on the washed 100% cotton body you will bulk. A clean unwashed sample does not authorize a washed program.
