Question

In the warp knitting machine the formation of loops is due to __________ motion of guides.

• A. rotating
• B. swinging and shogging
• C. negative
• D. vertical

Hint:

In warp knitting, "Swing" gets you in position, and "Shog" does the wrapping. You need both to knit!

Answer 1

The Correct Option is B

Concept: Warp knitting is a method of fabric formation where loops are formed from a set of warp yarns running parallel to the fabric length. This requires precise movement of the yarn guides around the knitting needles.

Step 1: Understanding Guide Bar Movements.
To form a stitch in warp knitting, the yarn guides must perform two specific synchronized movements:
• Swinging: The guide bar moves "through" the needles (front-to-back or back-to-front) to position the yarn for the next step.
• Shogging: The guide bar moves laterally (sideways) along the needle bar. This lateral movement is what actually wraps the yarn around the needle hook (overlap) or under the needle (underlap).

Step 2: Conclusion on Loop Formation.
The combination of swinging and shogging motions ensures that the yarn is correctly presented to the needle to form a new loop and connect it with the previous course of loops.
