Small products, big use! This chemical fiber "supporting role" is not a "walk-on"

"China is in urgent need of collaborative research on key functional material preparation technology, masterbatch efficient preparation technology, spinnability quality control, and fiber application." Ji Peng said.

"Domestic goods" urgently need to supplement the weak board

At this stage, with the scale and industrial chain advantages of leading chemical fiber enterprises becoming more obvious, the demand for oil agents is growing, and the production technology and innovation ability of oil agents are also put forward higher requirements, especially the demand for oil stability is more prominent.

"The spinning speed of melt direct spinning of large polyester enterprises is very fast, and the spinning speed of some varieties reaches 5000 meters/minute, and the spinning speed of POY products is usually 3000 meters/minute." In the case of such a high spinning speed, the oil loading time is very short, generally only 0.01ms-0.02ms. In such a short time, how to ensure that the oil is evenly dispersed on the surface of the fiber is very demanding, but also to ensure that the fiber has a low coefficient of friction." Cui Li introduced, "In particular, whether the oil of POY products is uniform will also affect the elastic wire. For example, the hot box temperature of the elastic wire reaches 180 degrees Celsius, and the hot box temperature of some special elastic wire is even as high as 200 degrees Celsius, which puts higher requirements on POY oil agents."

However, whether it is polyester or nylon enterprises, the general feeling in the process of using domestic oil and imported oil is that "the stability of domestic oil needs to be improved."

The function and quality of masterbatch also need to be improved, and the functional masterbatch required by some differential fibers is missing, and it is necessary to strengthen targeted research in the field of segmentation. In addition, relevant standards need to be improved.

In the next step, how to strengthen the advantages of the industry at the same time, to further supplement the weaknesses, strong and weak items?

Pan Yi said: First, it is necessary to build an interactive platform between oil additive production enterprises and chemical fiber production enterprises; Second, we should continue to further promote the research work of the oil additives industry, and form a stable communication channel and information notification mechanism in the industry; Third, explore the cooperation mechanism between the oil Additives branch and the National Advanced Functional Materials Innovation Center; Fourth, we should continue to improve the technical standards of the oil industry, promote the sound development of the industry, and focus on promoting the industry standards of polyester, nylon FDY and POY; Fifth, we should strengthen the industry self-discipline, regulate the industry behavior, avoid disorderly competition, jointly promote the healthy development of China's oil additives industry, and enhance the market competitiveness of China's oil additives.

Chen Xinwei suggested: First, the independent innovation ability of enterprises still needs to be enhanced, and it is necessary to further strengthen the basic application theory research, achieve technological breakthroughs and realize industrial application, and ensure the stability and security of the industry; Second, the product structure still needs to be optimized, the special oil for the localization of high-end fiber products has not been completely solved, and high-grade and high-quality masterbatch manufacturers are still fewer; The third is to strengthen the effective collaborative innovation and development of the upstream and downstream of the industrial chain, and relevant enterprises should take the initiative to carry out joint research and development with chemical fiber enterprises and raw materials enterprises. Fourth, the level of green development still needs to be improved, the green, environmental protection and performance of raw materials need to be further enhanced, and the recycling technology also needs to be further studied.

"Sufficient supply and stable quality of chemical fiber oil additives and masterbatches are the prerequisite for safe selection by the chemical fiber industry." Only by solving these problems can we provide more possibilities for the chemical fiber industry to further improve quality and develop functional fibers." Chen Xinwei said.
