Abstract

Since modern times, China has been forced into the huge wave of world industrialization. Yang Yuelin, a famous textile engineering expert and educator, is one of the countless people with lofty ideals who want to serve the country and embark on the road of "saving the country through industry". Yang Yuelin wrote a book "theoretical and practical sizing theory" after he learned the sizing technology of China and the West. The sizing principles summarized in the book constitute the theoretical basis of "sizing working method" of Qingdao Textile administration, which has a great driving role for sizing work in China. In the early days of the founding of the people's Republic of China, Yang Yuelin also actively responded to the call of the state and actively participated in the summary and promotion of the "Hao Jianxiu spinning method", which greatly encouraged the enthusiasm of the textile workers and their enthusiasm for production.
