Also important was mechanized spinning of thread. https://www.sleuthsayers.org/2013/06/the-3500-shirt-history-lesson-in.html https://www.sleuthsayers.org/2013/06/the-3500-shirt-history-... cites making a shirt in the middle ages as 7 hours of hand-sewing, 42 hours of hand-weaving, and 500+ hours of hand-spinning. https://thefreelancehistorywriter.com/2015/10/23/was-medieval-spinning-womens-work-a-guest-post-by-katrin-kania/ https://thefreelancehistorywriter.com/2015/10/23/was-medieva... has much higher estimates of spinning rates, but would still result in at least 40 hours of spinning (9000 yards from that first post divided by the 200 m/hr very generous overestimate from the second post; estimates of spinning speed seem to vary _very_ widely). One difference, of course, is that weaving was much more centralized to start with (spinning needed next to no machinery and a lot less training), so the economic impacts were very different.
