Look from the downstream demand for industrial fiber development direction

Release time: 2018-10-26

From the operation of the latest data can be seen, the trend of the overall operation of China's chemical fiber industry is not good, the overall industry performance is relatively low, a substantial reduction in profits, as one of the downstream chemical fiber textiles industry is outstanding. Statistics show that 1~4 months of this year, the domestic textile industry GDP growth rate reached 19.44%, much higher than the industry average. Experts predict that the overall decline in the quality of the overall operation of the industry environment, this year the industry with two digit growth in textile industry more secure. As the upper reaches of the industry, to fully understand the current situation, problems and needs of the industry in the use of fiber, it is crucial.

Fiber for filtration and separation: should follow the trend

High fiber technology research of Sichuan Province Textile Science Research Institute director Wang Hua told reporters that the varieties of filter material growing is an indisputable fact, from single material is natural fiber, synthetic fiber, inorganic fiber and metal fiber, and in recent years China has also developed including aromatic polyamide, polyimide, PTFE high temperature filter material, from a variety of process parameters and finished the experiment, but also to meet the basic needs of domestic dust emission enterprises. Such as PTFE, its maximum temperature can reach 260 degrees celsius. But in my opinion, technology is not the most worthy of concern, more attention than technology, I think there are two points." Wang Hua said, including the specialized production of filtration and separation in textile fiber production enterprises, production enterprises, the majority of domestic fiber does not understand the latest trends and development level of foreign fiber production therefore, blocking the news has become many enterprises of poor development can only do one of the stumbling blocks of low-end products; "there are some enterprises with a love in material production habit, and give a better choice, this is very unfavorable to the development of enterprises."

In addition to dust filtration, liquid filtration is also a major area of application for filtration and separation. According to Tianjin University of Technology party secretary Zhang Hongwei introduction, the current domestic components to the fiber must first have a strong capability of anti pollution water treatment, but the current domestic production enterprises of most fiber technology is unable to meet the above requirements, generally still rely on imports." In recent years, Tianjin University of Technology has made some progress in this regard. It is understood that the current Tianjin university system adopts the technology of radiation grafting of large flux and high pollution resistance of PVDF PVDF hollow fiber membrane preparation, anti pollution compared with the traditional technology is improved by more than 50%, in addition, due to the low energy consumption technology, also reduced the level of more than 15%.

Geotechnical and construction fibers: Market Segmentation

For soil and building textiles, due to its special filtration, drainage, isolation, reinforcement, seepage control, protective effect, also related to fiber strength, elongation, the super wear resistance, acid and alkali, fiber degradation, aging resistance, sound insulation, flame retardant and other functional requirements. To speed up the functional woven or knitting geotextile, geomembrane (grid) development and application, focusing on new geo ecological development of textile industry technology breakthrough, permanent membrane structure materials for light construction, processing technology development of new high technique of geosynthetics, is the future development direction and requirements.

Shandong Hongxiang Chemical Fiber Group Co., Ltd. chairman Cui Zhanming told reporters that the geosynthetics are mainly polypropylene staple fiber, polyester staple fiber, polyester filament, glass fiber, split film yarn, carbon fiber, etc..

"At present, the geosynthetics have not formed a market segmentation, differentiation and professional targeted poor, recycled fiber more, in this area, the development of high-performance fiber has yet to be improved." Cui Zhanming said.
