Lesson 12:Plain Weave

Ribbed weave

This is an unbalanced plain weave with warp yarn count about twice that of filling yarns. Ribbed or corded effects as they are termed are created when either two or more warp yarns together interlace as one yarn with the individual filling yarns, or two or more filling yarns together or interlace as one yarn with individual warp yarns. The ribs may be created either in the warp or filling direction of the fabric.

Warp ribbed fabrics are also called as waled or corded. Extremely short-staple yarns or yarns with insufficient twist or inferior yarns are used especially when the yarns that make the rib are hidden in the thickness of the cloth. The repeat is on four ends and two picks and can be done on two harnesses.

Characteristics:

1. Fabrics are reversible unless printed
2. Durability is sacrificed when the ribs are too pronounced as they tend to pull away from adjacent fine yarns.
3. Yarn slippage and separation is observed more in filament fabrics
4. Fine rib fabrics drape well than the ones with more body but the later are good for bouffant look.
