Abstract In response to the high failure rate and poor product quality in the preparation of copper-ammonia fibers as described in textbooks, this paper provides an overview of existing research on improvements. It proposes a pathway for improving the experimentation process of preparing copper-ammonia fibers from an “integration of science and engineering” perspective. Aiming for “speed, simplicity, and efficiency”, this study conducts a theoretical analysis and comparison of various experimental schemes to explore better experimental conditions. Building on this, it further simulates the wet spinning process used in industry, integrating elements of scientific and engineering thought to design a “Copper-Ammonia Fiber Spinning Process Simulation” experiment. In conjunction with the historical development of the copper-ammonia fiber production industry, this paper discusses the value and implications of “integration of science and engineering” thinking.
