Provide support for the rapid development of chemical fiber industry! China Chemical Fiber melt injection, masterbatch and oil additives advanced technology conference

It is understood that the master batch adding methods include screw adding weightlessness type, screw adding volume type and melt injection. Melt injection system refers to the method of spinning differential fibers by adding another melt (such as colored masterbatch, modified masterbatch, etc.) in the chemical fiber spinning system. Compared with screw added weight loss type and volume type, melt injection can be suitable for direct spinning and slice spinning, the biggest difference is that the product quality of melt injection is controllable, the core technology of melt injection is dynamic mixer, its dynamic mixing effect is good, dyeing uniformity 100% reaches 4.5 level, and the product has no color difference. It can be said that melt injection system provides an effective technical platform for chemical fiber manufacturers to develop and produce new products and improve the quality of differentiated fibers.

Since 2013, Zhejiang Hengyi Polymer Co., Ltd. has cooperated with Wuxi Juxin Company to develop a melt injection device (18 bits/set). Through continuous run-in, the device now operates reliably and the product quality is recognized by users. Wang Xingang, assistant general manager of Hengyi Polymer, recalled the background of the cooperation at that time, when the company's traditional conventional spinning device basically had no space to survive, the company has been thinking about how to make these old devices and old equipment run again through transformation. Later, we cooperated with Wuxi Juxin to transform these old devices and old equipment, and developed the melt injection device, which can be said to be a major change and milestone in the chemical fiber direct spinning industry. At present, Hengyi Polymer company has more than 20 sets of melt injection adding devices, most of which are used in the old production line, with stable product quality and reliable operation of the device.

As a front-line user for many years, Wang Xinguang spoke highly of Wuxi Juxin's melt injection system: it has promoted the technological upgrading of the chemical fiber industry and improved the product grade of the chemical fiber industry; Reduce the consumption caused by product replacement; Adjust and optimize the product structure of the industry, saving national resources; Leading China's chemical fiber industry to the world, from running to leading.

For the future of melt injection devices, Wang Xingang suggested not only going abroad, but also continuing to expand other application areas, such as: It is used in nylon 66 spinning, nylon 6 spinning, viscose industry, staple fiber PSF industry, direct spinning online addition of functional batches, online addition of composite spinning (such as island silk), industrial silk and injection of bottle sheet spinning, etc., using this technology to upgrade and iteration of products. In terms of energy consumption, it is hoped that the technology will be broken through again, and the melt injection device with low energy consumption and more competitive will be developed. In the aspect of data, the remote operation and maintenance system is realized, including equipment management, quality management, predictive maintenance and other modules, which optimize the operation dynamics of the device through the implementation of data collection and analysis, and are always in a controlled state; In terms of intelligence, it is hoped that the equipment will be more intelligent, such as the automatic opening of the freezer valve and the automatic closing of the three-way valve.

Masterbatch: Leading the green development of chemical fiber industry

Wang Baozhu, deputy chief engineer of Suzhou Baolidi Material Technology Co., Ltd. introduced the development and application of chemical fiber direct spinning masterbatch in intelligent addition system. Politi has gone through 23 years of wind and rain, is the leading research and development, production and sales of chemical fiber special masterbatches of professional manufacturers, main polyester, nylon special masterbatches and functional masterbatches, in the chemical fiber masterbatches industry in a leading position. At present, the company has established a solid cooperative relationship with many well-known chemical fiber manufacturing enterprises such as Rongsheng Petrochemical, Shenghong Group, Hengli Group, Hengyi Petrochemical, Yizheng Chemical fiber and so on.

Especially with the successful application of dynamic mixing system developed and produced by Wuxi Juxin Technology Co., Ltd. in direct spinning production line, the application range of color masterbatch products in chemical fiber production has expanded from slice spinning to melt direct spinning production line. Therefore, according to the equipment characteristics of the direct spinning on-line addition system and the characteristics of the masterbatch melt, the development of color masterbatch has been improved in the aspects of plasticization, fluidity, dispersion filtration and spinnability. In response to the current trend of intelligent manufacturing, Polaroid has also developed an intelligent color matching system and launched the Polaroid universal color card, which has achieved good benefits.
