Technological Innovations of French Jacquard Silk Weaving in the 19th Century

The emergence of the jacquard loom in the early 19th century was one of the most important mechanical inventions among the technological innovations of the French silk weaving industry. Since then, France continuously optimized and improve jacquard loom, resulting in many technological changes. Based on the technical principle of different types of jacquard looms in France in the 19th century, and by referring to literature and conducting field visits to France and other places, our study systematically analyzed and summarized the technological changes of jacquard in French silk weaving in the 19th century. These changes mainly included the modification of crochet shape, direction and thickness of placement, the change of the shape and material of pattern card, the size and arrangement of its holes, and the addition of harness cord and shaft monture, so as to promote the continuous, rapid and steady progress of the whole silk weaving industry.
