So the seam might not be a good indication whether or not it's made on a circular machine. 13:20 plain weaves have significant stretch on the diagonals. adding yarn in these directions makes for the actual stiffest fabric. 14:14 they did have more complex weaving structures before the industrial revolution, of course. My bad. I wanted to make a good transition to the modern machines. 17:50 water jet looms are quite rare as it turns out. Air jet looms seem much more common. 19:05 Besides the amount under-over, one of the deciding differences between twill vs satin weaves is also how many yarns you move over to the side on the next row. A twill weave will give these diagonal lines because on the next weft yarn you do the "1 over" on the very next warp yarn. But a satin weave will skip one, or multiple yarns. So the diagonal pattern will seem to disappear. Photo credits: All video is made by me. Many pictures too, but not all. Those that I didn't make came from Wikipedia.
