When we talk about the circulation of sciences and technology, the first idea appeared is mostly the introduction of European knowledge into China. In the present paper, I will focus on the introduction of Chinese knowledge into France. In the case of silk industry, I will examine how French scholars and industrialists “translated” Chinese silk know-how into French and how they assimilated the information for silk industry mechanization. As we know at the end of the 17th Century, one of the essential objectives for sending the French Jesuit mission into China was to collect Chinese knowledge and know-how for improving French silk industry which started to flourish since several decades earlier. Even though French artisans succeeded to weave figured silk fabrics, the quality was far below that of the silk imported directly from China. On the one hand, the low productivity of raw material and the poor quality presented a severe obstacle. On the other hand, the French weaving loom demanded more time for producing silk weaving goods weakened obviously the competitiveness of French silk industry. In this presentation, I will use the manufacture of silk goods as an example to examine the process in which the French collected Chinese knowledge, then analysed, and adopted it to develop their own technology. They finally succeeded in create mechanical weaving looms in order to reduce manpower and the amount of time for making silk goods.
