Handloom production expanded rapidly in the 20th century, especially between 1900 and 1940. The driving force for this was technological changes. Every time a new technology was introduced in the handicraft industry, it enabled them to improve their products without an extreme increase in the costs. By the second decade of the twentieth century, a new technology with the fly shuttle was introduced in most of the mills. Fly shuttle is a device used for weaving with the help of ropes and pulleys. It enabled the weavers to operate larger looms. This increased the productivity of the handloom mills even though it reduced the demand for workers.
