Do you really understand the development history of spinning machines? The following are the different historical stages of the development of spinning machines.
The process of twisting loose fibers into lines and drawing and twisting them into yarn is called spinning. The earliest tool used for spinning in our country is spinning. There is no way to check the exact time of the appearance of spinning. However, the main part of the spindle, the spinning wheel, appeared in the archaeological excavations at the Cishan site in Hebei, indicating that there was a spindle more than 7,000 years ago. A large number of stone or pottery spinning wheels were unearthed at the Hemudu site in Zhejiang, the Banpo site in Xi'an, Shaanxi, and the Jiangzhai site more than 5,000 years ago, indicating that the spindle has become the main spinning tool at that time.
2. Hand spinning wheel
When using a spindle to spin yarn, because the force of the hand twisting the hammer rod is large or small each time, the rotation speed of the spindle is fast and slow, and the spun yarn is extremely uneven. Moreover, when the hammer rod is rubbed once by hand, the spindle can only run for a short period of time, spinning a short length of yarn. With the rapid increase in yarn demand in the weaving process, the defect of low spindle efficiency has become more and more obvious, making people have to create new spinning tools to replace them. In people's practice, hand-cranked spinning wheels have emerged.

The pedal spinning wheel is developed on the basis of the hand spinning wheel. Although it has the same function as the hand spinning wheel, the former has an improved structure. The driving force of the spinning wheel comes from the feet, not the hands. The force exerted by the foot drives the rope pulley and the spindle to make continuous circular motions through the added pedals, spikes and cranks and other transmission parts, so that the spinning woman's right hand used to shake the spinning wheel is released, and it is carried out with both hands. The operation of spinning or threading. The pedal spinning wheel not only makes up for the fact that the hand spinning wheel only uses one hand for spinning work, it is difficult to well control the short fibers, such as silk or short filaments, and the fibers are easy to kink with each other during spinning, resulting in uneven yarn thickness. Defects also greatly improve production efficiency.

During the Tang and Song Dynasties, due to the great development of social economy and commodity trade, the society's demand for textiles greatly increased, and there appeared many laborers who separated from agricultural production and specialized in hand-made textile production. Spinning with the original hand spinning wheel and pedal spinning wheel can no longer meet market needs and specialized production. How to improve spinning productivity has become an urgent technical problem raised by the society to be solved, so it is the foundation of various spinning machines handed down from generation to generation. In the past, a large spinning wheel with dozens of spindles was gradually produced.
