The invention relates to a spinning process cascade modeling segmented interval parameter configuration method. After multiple groups of polyester fiber spinning process segmented parameter value intervals are randomly generated, the performance index value interval of each group of corresponding polyester fibers is predicted, and after one group of polyester fiber spinning process segmented parameter value intervals is selected according to the performance index value intervals of the polyester fibers, configuration is carried out accordingly. Before prediction, a polyester fiber production process is divided into a plurality of main body prediction sections A1-Am according to a polyester fiber spinning process; an error prediction section Bi is additionally arranged between a main body prediction section Ai and Ai + 1, the whole prediction process is the process of sequential prediction of all prediction sections, an algorithm model corresponding to the main body prediction section is an improved IRBFNN algorithm model, and an algorithm model corresponding to the error prediction section is an IPSO-ELM algorithm model. The configuration method is simple in process, short in consumed time, free of repeated tests, low in cost, high in operability and high in practicability, and can overcome the defects of establishing a point value model in the polyester fiber spinning process.
Description
technical field [0001] The invention belongs to the technical field of parameter configuration of polyester fiber production, and relates to a segmental interval parameter configuration method for cascading modeling of a spinning process. Background technique [0002] Polyester fiber is a fiber spun from a fiber-forming polymer formed by linking macromolecular chains through ester groups, referred to as PET fiber, commonly known as "polyester", which has good wrinkle resistance and shape retention. In addition, it has high strength and elastic recovery ability. Polyester has excellent physical, chemical and mechanical properties, so it quickly becomes the most productive variety among synthetic fibers. The polyester industry has also become an industry closely related to the national economy and the people's livelihood, and is widely used in various aspects of the national economy such as chemical fibers, light industry, electronics, and construction.
