Zhejiang Modern Textile Industry Research Institute Material Science The Institute recently launched the first new model. Spinning port Heating equipment. The device is an independent unit attached to the spinning equipment. It is composed of two parts: induction heating system and remote control system. It can be used in various melting processes flexibly. spinning The equipment does not change the structure and process of the original equipment.

Spinneret - generally refers to the spinneret outlet of the spinning assembly, where the melt becomes a fine stream and becomes primary silk by cooling, solidification and stretching. As a key process control point, the role of spun port heating can not be underestimated. First, the heating of the spinneret makes the spinneret generate uniform heat energy, and achieves precise control. Based on the original environment, the continuous consistency of the plate temperature is achieved, ensuring that the melt flow from each hole is uniformly heated, and the continuous steady state of the monofilament is ensured from the source. Secondly, without changing the original technology, setting the temperature of the spinning port to the same temperature as the spinning box can reduce the solidification point 3~10cm, and the elongation of the winding fiber increases obviously. Technology The drawing ratio of the nozzle can be increased, and the production capacity will be increased by at least 2~3% after adjusting the process. Thirdly, the temperature of the spinning port can reach a higher temperature than that of the spinning box, so as to achieve the new process design of "melt relative low temperature spanportation in the pipeline and instant spinning at high temperature". These three functions can lead to many design directions such as product performance, product variety and product category.

The patent technology pioneered by the Institute of new materials, Zhejiang Institute of modern textile industry, has been vigorously promoted in the implementation of the national support plan, and has achieved fruitful results: the average strength of the new polyester industrial yarn in the field of high-strength industrial yarn reaches 8.7CN/dtex, which is the most advanced level in China at present and is also fully capable of upgrading the index to the international advanced level. In addition, the technical team of the new material research institute has perfected the technology of the heating system of the spinning port through the accumulation of practical experience for many years, and can provide different product design schemes according to the production type of the enterprise.
