1x1 Rib
Nature — What Is 1x1 Rib?
1x1 Rib is a knit fabric constructed by alternating one knit stitch and one purl stitch across the width (1 knit + 1 purl sequence).
This creates vertical rib columns that are highly elastic and reversible.
Scientific Structure (Explained Clearly)
1x1 rib is produced on a double needle bed knitting machine where front and back needles alternate forming interlocking vertical ridges.
Structural Characteristics
- Alternating knit and purl stitches (creates vertical ribs)
- Double needle bed construction (improves elasticity)
- Symmetrical front and back (reversible appearance)
Fabric Quality Impact
- Excellent stretch and recovery
- Snug body-hugging fit
- Medium weight depending on yarn
Performance — How 1x1 Rib Behaves
1. Stretch
Extremely stretchy across the width due to rib structure.
2. Recovery
Good ability to return to original shape after stretching.
3. Fit
Conforms closely to the body, making it ideal for cuffs and waistbands.
4. Structure
More structured than single jersey but softer than heavier double knits.
