Spinning, the ancient craft of converting fibers into yarn, has run through the entire course of human civilization's development. From prehistoric hand twisting to the mechanical roar of the Industrial Revolution, and on to the automated production of modern smart factories, every breakthrough in spinning technology has profoundly transformed human society.
- The most primitive method: twisting fibers (such as bark, hemp, wool) on the thigh to form yarn.
- Extremely low efficiency, only meeting basic needs.
- A great invention of the Neolithic Age: fixing a stone or pottery disc on a wooden stick.
- Working principle: the rotating disc generates centrifugal force to stretch and twist fibers into yarn.
- Archaeological discovery: an iron spindle from the Western Han Dynasty unearthed in Mawangdui, Changsha (as shown in Figure 1).
- In the 5th century BCE, the horizontal placement of spindles in Shandong, China, connected the large wheel and spindle disc via a drive belt.
- Efficiency improvement: one rotation of the large wheel drives the spindle to rotate 70-80 times, 15-20 times more efficient than the spindle.
- Later improved into a foot-operated spinning wheel, freeing hands and greatly increasing production capacity.

- Invented in the late Southern Song Dynasty and popular in the Yuan Dynasty in China.
- Structure: equipped with 32 spindles, driven by water flow, capable of twisting 50kg of hemp yarn per day.
- Impact: the technology spread westward to Europe, inspiring Arkwright's water frame.
*Figure 2: Ancient Chinese Water-Driven Large Spinning Wheel*
- Invented by British weaver James Hargreaves in 1764.
- Inspiration: accidentally knocking over his wife's spinning wheel and noticing the fallen spindles could still rotate upright.
- Innovation: one machine driving 8 (later increased to 80) spindles simultaneously, multiplying efficiency several times.
- Significance: one of the iconic inventions of the Industrial Revolution, shifting spinning from family workshops to large-scale production.
*Figure 3: Spinning Jenny*
- Invented and patented by British watchmaker Richard Arkwright in 1769.
- Features: driven by water power to operate a roller system, producing strong and tough yarn suitable for warp threads.
- Impact: established the first water-powered spinning mill in 1771, initiating the factory system of production.
- Limitation: dependent on water sources, unable to operate during dry seasons.
*Figure 4: Arkwright's Water Frame (1775)*
- Invented by Samuel Crompton in 1779, combining the advantages of the Spinning Jenny and the Water Frame.
- Principle: spindles move back and forth on rails ("mule" movement) to achieve drafting and twisting.
- Production capacity: capable of driving 300-400 spindles, producing fine and strong yarn.
- Impact: by 1800, there were 600 "mule" spinning mills in Britain.

- Invented by American J. Thorpe in 1828, ushering in a new era of continuous spinning.
- Core components: ring (steel collar) and traveler (wire loop), enabling continuous twisting and winding.
- Working principle: the spindle drives the bobbin to rotate, and the traveler slides along the ring, applying one twist to the yarn per rotation.
- Advantages: simple structure, continuous production, wide spinning range, and still dominant today.
*Figure 6: Modern Ring Spinning Frame*
- Revolutionary breakthrough: eliminating the spindle, using centrifugal force from a high-speed rotating rotor (150,000 revolutions per minute) to condense fibers.
- Features: shortened processes (eliminating roving and winding), 3-5 times more efficient than ring spinning.
- Application: medium and coarse count yarns, widely used in denim, knitwear, etc.
- Latest technology: replacing traditional twisting with air vortex, spinning speed reaching 20 times that of traditional ring spinning.
- Advantages: high degree of automation, labor savings, fewer hairiness, and anti-pilling properties.
---
- Automatic doffing, cleaning, and piecing, increasing single equipment production capacity by 300%.
- Intelligent monitoring systems analyze yarn quality in real-time and adjust parameters automatically.
- Energy-saving technology: new spindle systems reduce energy consumption by 10%.
- Recycled fiber spinning: reducing CO₂ emissions by 1.8 tons per ton of yarn and lowering costs by 25%.

From a coarse thread between the fingers of ancient humans to the fast-paced intelligent production lines in modern factories, the evolution of spinning technology is a microcosm of human civilization's progress. Every technological breakthrough not only improved production efficiency but also reshaped social structures—from cottage industries to modern factory systems, from labor-intensive to intelligent manufacturing. The transformation of spinning technology has driven the development of the entire textile industry and even the global economy.
Today, when we touch soft clothing, we should perhaps be grateful for this thread that has traversed ten thousand years, as well as the innovative minds that have continuously pushed boundaries. It is they who have woven the warp and weft of human civilization.
