Why is a knitted fabric called French rib?

rib knitted fabric is a knitted fabric in which a single yarn forms loops on the front and back side in turn.

rib knitted fabric has the properties of shedding, curling and extensibility of plain fabric, and it also has great elasticity.

It is called French rib because the needle cylinder uses a kind of needle, which is called in some professional fields, because it is different from our ordinary 1*1, 2*2 ribs in the weaving process.

I hope the above answers can help you.
