Yarn Jamming

When the magnitude of the straight section of modular length is zero, then the pick spacing becomes minimum and such situation is called Yarn Jamming. Mainly Yarn Jamming is two types. They are:

1. Warp Jamming.
2. Weft Jamming.

Warp Jamming: When the fabric is extended to weft direction and magnitude of the modular length of the straight section of warp becomes zero, then the weft spacing is minimum. This condition is called warp jamming.

Weft Jamming: When the fabric is extended to warp direction and magnitude of the modular length of weft spacing is minimum, this condition is called weft jamming.
