In the late nineteenth century, the Western invention of synthetic dyes had a devastating effect on the traditional way of carpet production. During the early twentieth century, carpets were woven in the cities of Saruk and Arak, Iran and the surrounding villages mainly for export to the U.S. While the sturdy construction of their pile appealed to U.S. American customers, their designs and colours did not fit in with the demands. The traditional design of the Saruk rug was modified by the weavers towards an allover design of detached floral motives, the carpets were then chemically washed to remove the unwanted colours, and the pile was painted over again with more desirable colours.
