The elongation of polypropylene staple fiber is one of the main indicators for determining its quality. The fluctuation of the elongation of polypropylene staple fiber during the production process is studied and improved, which helps to improve the quality of the fiber. Therefore, the process control and test data of fiber production should be strengthened to accurately reflect the actual production and the quality control of the raw materials themselves.

There are many factors affecting the elongation of polypropylene staple fiber, both subjective and objective. This requires us to proceed from the reality, seriously study the problems of fiber raw materials, production technology and inspection, and scientifically guide production. The problem of fluctuation in elongation is solved to better improve the quality of the fiber.
