Explanation:
The spinning wheel was invented in India, between 500 and 1000 C.E. The earliest clear illustrations of the spinning wheel come from Baghdad (drawn in 1234), China (c. 1270) and Europe (c. 1280), and there is evidence that spinning wheels had already come into use in both China and the Islamic world during the eleventh century. In France the spindle and distaff were not displaced until the mid 18th century.

The spinning wheel replaced the earlier method of hand spinning with a spindle. The first stage in mechanizing the process was mounting the spindle horizontally so it could be rotated by a cord encircling a large, hand-driven wheel. The great wheel is an example of this type, where the fibre is held in the left hand and the wheel slowly turned with the right. Holding the fibre at a slight angle to the spindle produced the necessary twist. The spun yarn was then wound onto the spindle by moving it so as to form a right angle with the spindle. This type of wheel, while known in Europe by the 14th century, was not in general use until later. The construction of the Great Wheel made it very good at creating long drawn soft fuzzy wools, but very difficult to create the strong smooth yarns needed to create warp for weaving. Spinning wheels ultimately did not develop the capability to spin a variety of yarns until the beginning of the 19th century and the mechanization of spinning.

In general, the spinning technology was known for a long time before being adopted by the majority of people, thus making it hard to fix dates of the improvements. In 1533, a citizen of Brunswick is said to have added a treadle, by which the spinner could rotate her spindle with one foot and have both hands free to spin. Leonardo da Vinci drew a picture of the flyer, which twists the yarn before winding it onto the spindle. During the 16th century a treadle wheel with flyer was in common use, and gained such names as the Saxony wheel and the flax wheel. It sped up production, as one needn't stop spinning to wind up the yarn.
