What was a significant technical limitation of the thread produced by the Spinning Jenny?

Answer

It produced thread that was thin, weak, and unsuitable for the warp

Although the Spinning Jenny achieved a massive increase in volume, the quality of the thread it produced was constrained by its reliance on the drop spindle principle. The resulting yarn was thin and relatively weak, making it suitable as weft—the crosswise threads in woven cloth—but insufficient for the warp, which requires much stronger, longitudinal threads. This limitation created a new technological demand, eventually leading to the invention of the Water Frame to produce the necessary high-quality warp yarn.
