In weaving, it's all about keeping threads from doing what they want to do. A modern thread factory uses the same technology but at a much faster rate. Some machines use air which twists just the outside of the fibre. It creates a similar kind of effect and is quieter than other methods.
Author and journalist Virginia Postrel talks about her book The Fabric of Civilization and How Textiles Made the World with EconTalk host Russ Roberts. Postrel tells the fascinating story behind the clothes we wear and everything that goes into producing them throughout history. The history of textiles, Postrel argues, is a good way of understanding the history of the world.
