At the same time, the innovative development of textile and chemical fiber products also put forward new requirements for chemical melt injection, masterbatch and oil additives industry.

 

In December 2nd, China's chemical fiber melt injection, masterbatch and oil additives additives advanced technology conference (Wuxi Ju Xin 2019) was held in Shengze, Jiangsu. The meeting was held to speed up the development and transformation of new technologies and processes in injection molding, masterbatch and oil additives industry, to spread the latest trends in chemical fiber industry and textiles, and to grasp the new trend of chemical fiber, especially polyester and nylon products, and to promote the coordinated development of melt injection, masterbatch and oil additives and chemical fiber industry.
 
Chen Xinwei, vice president of China Chemical Fiber Industry Association, general manager of Wuxi poly New Technology Co., Ltd., Gu Zijiang, chairman of China Chemical Fiber Industry Association oil additives branch chairman Lu Guofeng and other relevant institutions, experts and entrepreneurs attended the meeting.
 
The meeting was sponsored by China Chemical Fiber Industry Association, China Chemical Fiber Industry Association oil additives branch, Wuxi poly New Technology Co., Ltd., China Chemical Fiber Industry Association polyester filament Specialized Committee, polyester and staple fiber Specialized Committee, polyester industry filament branch, nylon branch, Jiangsu new horizon advanced functional fiber Innovation Center Co., Ltd. support.
 

Chen Xinwei, vice president of China Chemical Fiber Industry Association, delivered a speech at the meeting. He said that in the 70th anniversary and 70 years since the founding of new China, fundamental changes have taken place in the chemical fiber industry in China. The output of chemical fiber has increased from 1 million 175 thousand tons in 1987 to 50 million 110 thousand tons in 2018, an increase of more than 42 times. In particular, the difference and functional level of conventional chemical fiber varieties, such as polyester, nylon, regenerated cellulose fiber and recycled chemical fiber, are constantly improving, and the products are more in line with the diversified practical needs of downstream.

Functional masterbatch, oil additives and auxiliaries are indispensable supporting materials for chemical fiber production and processing. They play an important role in fiber differentiation, functional development, quality improvement and cleaner production. In the United States, Germany, Japan and other countries, the research on chemical fiber agent additives has always been the leading technology, and the key preparation technology of new high efficiency oil and compound oil additives is always in the lead. Our country started late in this field, and developed with the growing of chemical fiber industry. Although it has already formed a certain scale and foundation, the technology level still has a certain gap compared with Germany, Japan and the United States. In particular, the key raw materials such as masterbatch, oil additives, functional additives, flame retardants, new modifiers, catalysts and so on, which support the development of high-end functional fibers, are still heavily dependent on imports, which is a major supply risk for China's chemical fiber industry.

In the future, with the continuous development of high quality in China's chemical fiber industry, not only will the dosage and demand of functional masterbatch and oil additives increase significantly, but also higher requirements for quality, technology and varieties of chemical fiber agent additives are also put forward. The main points are: reducing pollution in production and application process, reducing production energy consumption, realizing green development, improving product technology adaptability, stability, environmental protection and safety; strengthening matching monomer technology development, enriching product series, gradually realizing the substitution of imported products, changing the import dependence situation of high-end functional fiber oil additives, ensuring self supply and reducing the risk of industrial chain. In addition, we should further strengthen the standardized management of industries, improve product industry standards, and promote technical exchanges among industries.

Wu Wenjing, director of Information Department of China Chemical Fiber Industry Association summarized the historical experience of the development of the chemical fiber industry in the report, analyzed the current economic operation of the chemical fiber industry, and prospected the operation and development of the industry. The current Sino US trade friction and other factors have brought about multiple tests to promote the development of high quality in the chemical fiber industry. The pressure of the economic operation of the chemical fiber industry has increased significantly. But in the industry's insisting on deepening the structural reform of the supply side and actively coping with risks, the operation of the industry is generally stable.

Wu Wenjing believes that the downward pressure on the industry in the future is still great, and risks and challenges remain unchanged. We need to accelerate the development of high quality and enhance our ability to resist risks. With the gradual development of the national initiative to promote high-quality development, the development and operation of the chemical fiber industry will also play a strong support. The industry's own risk tolerance and development resilience will continue to improve. What the industry needs to do is to "manage its own affairs", strive to defuse risks, strengthen industry self-discipline, avoid undesirable competition, and reasonably control new production capacity.

In promoting the high quality development process of the chemical fiber industry, the development of functional, differentiated and high quality fibers such as polyester filament and nylon is still the primary factor to improve the operation quality of the enterprise.
 
Dr. Ji Peng, a key technology collaborative innovation center of the textile industry of Donghua University, introduced the development trend of the chemical fiber and the green development and innovation system. He pointed out that the functional, green, intelligent, high-value development of the fiber industry and the development of the whole industry chain are the new paths for the development of China's fiber industry. At the same time, the green and sustainable development of fiber has put forward new requirements for injection technology, chemical fiber masterbatch and oil additives. The report introduces the development trend and green development requirements of the functional fiber of chemical fiber. With the innovative elements such as chemical fiber injection technology, masterbatch and oil additives, flexible manufacturing technologies such as blending, blending, on-line adding and compounding of chemical fiber products are used to realize the green manufacturing and intelligent manufacturing of chemical fiber, which is the key to high efficiency, low cost, high quality and customization of fiber production.
 
Shen Shoubing, technical director of Shanghai mercury home textiles Limited by Share Ltd, introduces the development and application of functional fiber materials, promoting the great development of the home textile industry, enriching the types of home textile products, improving the quality and technology sense of the products, but in using it, we also find that there are some problems such as the lack of functional experience, the low fiber comfort, and the color of some fibers, such as carbon fiber graphene fibers, which limit their use.
In view of the increasing consumption demand, Shen Shoubing put forward suggestions on the research and development of functional fiber materials from the perspective of application: developing products with unique functions and new concepts, which can fill gaps in the market, and have unique technology and outstanding data performance in some indicators, so that new products can be seen, smelled and felt. Combined with years of operation experience of mercury textile, he suggested that fiber enterprises should listen more to customers' voices, develop jointly, provide solutions instead of selling products, provide the ultimate service, not only want to gain benefits, be honest and trustworthy, but do not ignore rules, focus on super performance price ratio instead of absolute price.

Melt injection: a revolution in chemical fiber spinning industry

Melt injection system is a method of spinning differential fibers in chemical fiber spinning system by adding another melt (such as colored masterbatch and modified master batch) through technical means. It provides an effective technology platform for new product development and production of chemical fiber production enterprises and improving the quality of differential fiber.

Wuxi poly New Technology Co., Ltd. has successfully launched the melt injection online adding system since 2010. It has been ten years since the introduction of the melt injection system in many famous melt direct spinning enterprises in China. At the meeting, Gu Zijiang, general manager of Wuxi poly new group, introduced the company developed masterbatch adding overall solution and melt injection intelligent diagnosis system.

It is known that the method of adding masterbatch includes screw adding weightlessness, screw adding volume and melt injection. Melt injection system is a method for spinning differential fibers in chemical fiber spinning system by adding another melt (such as colored masterbatch and modified master batch) by means of technology. Compared with screw added weightlessness and volume, melt injection can be used for direct spinning and slicing. The biggest difference is that the quality of products injected by melt is controllable. The core technology of melt injection is dynamic mixer, its dynamic mixing effect is good, dyeing uniformity is 100% to 4.5, and the product has no color difference. It can be said that the melt injection system provides an effective technology platform for new product development and production of chemical fiber production enterprises and improving the quality of differential fibers.
 

Zhejiang Hengyi polymer Co., Ltd. has been developing a melt injection device (18 bit / set) with Wuxi poly new company since 2013. Through continuous running in, the device is reliable and the product quality is recognized by users. Wang Xingang, assistant general manager of Hengyi polymer, recalls the background of cooperation at that time. At that time, the traditional conventional spinning device of the company had basically no room for survival. The company has been thinking about how to make these old devices and old equipment run again through transformation. Later, with the new cooperation in Wuxi, the old equipment and old equipment were reformed, and the melt injection device was developed, which can be regarded as a great change and milestone in the chemical fiber direct spinning industry. At present, Hengyi Polymer Co 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.

As a front-line user for many years, Wang Xingang highly praised Wuxi's new melt injection system: it promoted the technological upgrading of the chemical fiber industry, upgraded the grades of the chemical fiber industry, reduced the consumption of product replacement, adjusted and optimized the product structure of the industry, saved the national resources, and led the Chinese chemical fiber industry to the world, leading from running to running.

For the future of melt injection device, Wang Xingang proposed not only to go abroad, but also to continue to expand other applications, such as application in nylon 66 spinning, nylon 6 spinning, viscose industry, short fiber PSF industry, direct addition of functional masterbatch on line, composite spinning on line (such as sea island silk), industrial yarn and injection into the bottle, and so on. This technology is used to upgrade the product. In terms of energy consumption, we hope to break through the technology and develop a melt injection device with low energy consumption and more competitive power. In the data analysis, we must realize remote operation and maintenance system, including equipment management, quality management, predictive maintenance and other modules. We can optimize the operation state of the device through data collection and analysis, and always be in a controlled state. Intellectualized, we hope that the equipment will be more intelligent, such as the automatic opening of the refrigerating valve and the automatic closing of the three-way valve.

Color Masterbatch: leading the green development of chemical fiber industry

Wang Baozhu, deputy chief engineer of Suzhou Baoli Di material Polytron Technologies Inc, introduced the development and application of the intelligent adding system of chemical fiber direct spinning masterbatch.

It mainly specializes in polyester, nylon special masterbatch and functional masterbatch, and is in the leading position in the chemical fiber color masterbatch industry. At present, the company has established a solid cooperative relationship with Rongsheng petrochemical, Sheng Hong group, Hengli Group, Hengyi Petrochemical Company, Yizheng chemical fiber and many other famous chemical fiber manufacturing enterprises.
 
In particular, with the successful application of the dynamic hybrid system developed by Wuxi poly New Technology Co., Ltd. in the direct spinning production line, the application scope of the masterbatch product in the chemical fiber production is extended from the sliced spinning to the melt direct spinning production line. Therefore, according to the equipment characteristics of the direct spinning online adding system and the characteristics of the master batch melt, polydi has improved the research and development of the masterbatch in plasticizing, fluidity, dispersive filtration and spinnability. In view of the current trend of intelligent manufacturing, Paulidi also developed an intelligent color matching system and launched the Polaroid color card, which has achieved good results.
 
Wu Shengli, marketing manager of Cabot (China) Investment Co., Ltd. introduced the application and development of ultra black colorant in Masterbatch or chemical fiber. It is understood that Cabot Corporation spinning grade carbon black has been widely used in a variety of fibers, spinning grade carbon black provides elegant black fiber to meet the needs of consumers and the market. Spinning grade carbon black also provides excellent spinnability, so as to ensure that the spinning component replacement cycle is long enough and the production efficiency is high enough. The quality stability of spinning grade carbon black has great influence on spinning performance and production efficiency.
 
As a user, the representative of Jiangsu Hengli Group, Rongsheng petrochemical and new Feng Ming introduced that the company mainly uses black masterbatch and full dull masterbatch, and has been using the new melt injection system for many years, and the effect is very good. However, there are still problems such as low stability and short cycle of equipment.

Oil agent: larger space for future development

As an essential component of chemical fiber production, chemical fiber oil additives have become an important factor in the development of high quality fiber industry. With the development of new equipment, new varieties and new technologies of chemical fiber, we have entered a deeper level. Facing the stricter environmental policy requirements of the country, we urgently need to upgrade the development and production level of our chemical fiber agent additives.

In order to fully understand the development status of China's chemical fiber oil additives industry and understand the demand for chemical additives in chemical fiber enterprises, the Chemical Additives Association of China Chemical Fiber Industry Association organized the investigation of the chemical fiber agent industry. Li Ye, Deputy Secretary General of China Chemical Fiber Association oil additives branch, introduced the research situation. Research shows that factors such as lubricity, antistatic, cohesive, anti coking and gasification temperature, volatile components of the effective components of conventional fiber oil additives still affect the development of high quality fiber, and functional, differential fiber and hi-tech fiber oil additives are not targeted. Research enterprises believe that there is a big gap between domestic oil additives and imported oil additives in terms of product performance and new product development capability. It is suggested that oil companies should intensify their efforts in industrial chain linkage, standardization, green environmental protection, product performance improvement and new product development.
 
Zhong Min, Shanghai Duolun Chemical Co., Ltd. introduced the development and application of high efficiency environmental protection oil additives for high speed spinning of chemical fibers. The continuous progress of the chemical fiber industry has provided a new platform and opportunity for the chemical fiber oil agent. The development and application of the new environmentally friendly and efficient chemical fiber oil agent has also become a key project popularized by the textile industry.
