| Polyester industrial yarn is a high-strength polyester filament, and high-strength polyester industrial yarn is the most widely used. In recent decades, polyester industrial yarn production plant capacity in our country gradually increased.But compared with foreign countries, the product performance is poor and variety is less. This design through in-depth study of the basic theory, and contrast the characteristics of domestic and foreign ripe for the SSP and spinning winding production technology and equipment, decided SSP process of Toray, spinning process of Dalian Synthetic Fiber Research and Design Institute Co., Ltd. and winding process of TMT to produce high-strength polyester industrial yarns. Meanwhile, the design detailed analysis of the impact of process conditions on the solid-state reaction rate and product quality of high-strength polyester industrial yarn, in which I used a capillary rheometer for the study of the high viscosity polyester rheological properties and a dynamic mechanical analyzer for the study of the dynamic viscoelasticity of protofibers, identified by the process conditions. According to the production capacity and specifications, using the relevant the formula to calculate process parameters and to select major equipment.The design selected general equipment of the parts of SSP and spinning winding, process materials and energy, accounting for process materials and energy, determining the amount of public works, the part of construction, and estimated budget.Combined with process, the size of equipment, the installation of process piping, the principle of plant layout to draw the flow chart and floor plan of the parts of SSP and spinning winding.The characteristic of the design is energy efficient and low-cost. It overcomes the crystalline air into nitrogen technical problems, greatly reducing the nitrogen consumption. The self-pressurization sealing type of spinning components ensures uniformity of spun fiber structure. |
