Study on the Importance of Lei’s High Draft

High draft is an important procedure in the spinning which is a crucial step in textile engineering. Lei Binglin as a famous textile engineer invented Lei’s high draft in 1936 which not only made a contribution to modern China’s textile but also showed Chinese independent innovation to the world. So it is significant to research the role of Lei’s high draft in the process of spinning, the inheritance and innovation of high draft invention made by Lei Binglin and encourage given by country for Lei’s high draft. By analyzing all these aspects mentioned before, we would conclude the importance of Lei’s high draft in this thesis.
