Yarn Preparation for Weaving and Knitting

Definition:

                  Yarn preparation involves those processes that improve the yarn’s weaveability or knittability.

Preparation Requirement for Weaving Yarn: Warp Yarns:

1. Yarns must be aligned properly
2. Yarn strength must be increased
3. Yarn hairiness must be decreased
4. Yarn smoothness must be increased
5. Yarn elongation and flexibility must be sustained

Filling Yarns: 
Yarn must be wound properly and on a suitable package for high speed unwinding

Preparation Requirement for Knitting Yarn: Weft Knitting:

1. Yarn friction must be decreased
2. Fiber shedding must be decreased
3. Yarn smoothness must be increased 

Warp Knitting: 

1. Yarn friction must be decreased
2. Fiber shedding must be decreased
3. Yarn smoothness must be increased
4. Yarns must be properly aligned for introduction to knitting needles
