Answer :
Because it is more cost-effective to create weft-knit fabrics in this way, their stripes run in the fabric's breadth direction. Weft knits are produced by feeding yarn into the knitting machine, which then knits across the width from side to side (or in a circular pattern).
The production of weft knitted fabric involves precise needle movement. Cams are used as the needles' guiding mechanism. The knitting needles are moved into place by the cam mechanism. In the needle head is where the loop from the previous production cycle is located.
By weaving threads, we can make woven fabrics. On a loom that holds the yarns in place while the weaving process takes place, they are frequently woven together. The warp and weft of woven materials define the weave's direction.
