Industrial sewing is a technique in which fabric is sewn directly onto a fabric surface.
It is similar to knitting, except that the fabric itself is sewed to a fabric piece.
The fabric is then sewn onto the fabric piece by piece.
When finished, the finished product is a fabric that has been knitted together, as opposed to woven, which takes more time.
