The earliest loom in China was invented in which dynasty?

The earliest loom in China was invented in the Shang Dynasty, and the jacquard machine was developed in the Zhou Dynasty. At least at the end of the Warring States period, pedal looms have been used. Using the pedal as a heald lifting device (a device that separates warp threads up and down on the loom so that the shuttle can pass through) can free up both hands to pick the shuttle, and the efficiency is greatly improved. This loom is an epoch-making invention in the history of textile technology. In the early years of the Western Han Dynasty, the loom was further improved, and some people even invented a new jacquard machine. It uses 120 warp and can weave a jacquard in 60 days. However, the biggest feature of this twill loom is that each warp uses a pedal, so that 120 warp will have 120 pedals, which is laborious and time-consuming, and the operation is inconvenient. Later, someone improved it and simplified it to "fifty is fifty" or "sixty is sixty."
