Binding ratio
Self-fabric or rib binding width and elastane recovery matched to body shrinkage — not a generic fold.

Stopping Binding Roll and Armhole Gape on Training Tanks
After wash the crew binding rolled outward and the armhole opened on raise — buyers read that as a cheap tank before they read the GSM.

Direct answer
After wash the crew binding rolled outward and the armhole opened on raise — buyers read that as a cheap tank before they read the GSM. — anonymous engineering note on library block EL·MK-310. Remake samples From 1 piece (typically 7–9 working days); bulk 150 pieces per style per colour.
Problem
After wash the crew binding rolled outward and the armhole opened on raise — buyers read that as a cheap tank before they read the GSM.
Hardest moment
Coverage vs curl: a wider binding looked stable on the table but still flipped after wash; a tighter armhole held the bind but cut the shoulder on press. Ratio, depth and stitch had to move together.
Levers we locked
Armhole depth
Armscye dropped and front/back balance reset so the bind sat on the body line through an overhead press.
Stitch balance
Coverstitch tension set so the edge did not rope or roll after the wash programme.
Validation
- Wash dimensional stability on body and binding
- Overhead raise and press check for gape
- Edge roll review after dry
