A **side-seam twist (spirality) test** measures how far the side seam rotates away from the approved plumb line after a defined wash and dry cycle. For Weavnora **100% cotton heavyweight or washed T-shirts** in the **220–300 GSM** range, plus related hoodies and casualwear, approve twist on the finished washed sample before the **1,000-piece style MOQ**. This protects NA/EU brands from skewed side seams, uneven print alignment, and retail returns.

How should buyers define the after-wash spirality test?

Include these controls in the tech pack and RFQ:

1. **Garment state** — measure twist on the finished sample after the approved wash recipe—not only on greige fabric.

2. **Marking method** — mark hem, underarm, and side-seam reference points before wash; photograph the plumb alignment.

3. **Wash recipe** — lock temperature, chemistry, load size, and drying method used for bulk.

4. **Twist metric** — record degrees of rotation or millimeter offset at hem and chest; avoid vague “looks twisted” notes.

5. **Size coverage** — check at least the extreme sizes in the assortment; spiral risk can differ by size.

6. **Pass gate** — approve numeric tolerance and visual appearance before bulk cutting.

When should side-seam twist be checked against the finished garment?

Check twist after sewing, pressing, and the approved garment wash—not only on open fabric. Measure the first sample relaxed, then after the wash recipe and drying method signed for bulk. If yarn, knitting tension, wash chemistry, softener, dryer setting, or pattern balance changes, repeat the spirality gate before releasing the 1,000-piece style MOQ.

“Approve side-seam plumb after the bulk wash recipe; record twist degrees or hem offset, wash lot, dryer setting, and buyer tolerance on the sample QA sheet.” — common buyer QA practice for spirality approval

How can buyers prevent spirality complaints in bulk?

  • Keep the approved washed sample and plumb photos with the tech pack and purchase order.
  • Match knitting balance, sewing tension, an

  • Compare multiple colorways; darker or heavily washed lots can show twist differently.
  • Inspect first-off bulk pieces before full sewing and quarantine lots outside the signed tolerance.
  • Confirm whether screen print, DTG, embroidery, or special print placement amplifies visual twist.

What should the RFQ say about side-seam twist QC?

State the T-shirt style, target GSM within 220–300, wash recipe, drying method, twist metric and tolerance, size range, decoration method, and NA/EU destination. Ask for an after-wash spirality sample before bulk and identify the 1,000-piece style MOQ. Email **postmaster@weavnora.com** or request a sample at https://weavnora.com/#quote.
