　　抚摸挂在架子上的海藻纤维，手感十分顺滑。正当众人对海藻吐丝啧啧称奇时，工作人员告诉记者海藻纤维的神奇之处并不只是如此。拿起一把海藻纤维，工作人员拿打火机火苗对着海藻纤维烤，结果在火苗烧灼之下，工作人员手中的海藻纤维只是与火苗接触部位变黑，而并没有被点燃。工作人员表示，这只是�The algae fiber undergoes a carbonization reaction under high-temperature burning. The staff explained to reporters that this is because seaweed fiber is a kind of flame-retardant fiber. It is flame-retardant itself. The fiber has a high degree of carbonization during the burning process. It will be extinguished when it leaves the flame and will not cause an open flame in the air. Seaweed fiber is an ideal material for flame retardancy. Clothing made of it is safer than traditional cotton, linen and chemical fiber clothing in case of fire.

　　据海藻纤维专家夏延致教授介绍，海藻纤维在青的研究早可追溯到2003年海藻纤维的研发被列为青岛市科技将才计� . There are many technical difficulties faced in the early stage of seaweed fiber development, mainly including: first, the fiber spinning raw material is not dedicated, and there is no special detection and control method for the raw material alginic acid segment structure G/M, which also results in low fiber strength and poor fiber quality. An important reason why the quality is easy to change; secondly, seaweed fiber does not have industrial production equipment and cannot truly achieve continuous production. Domestic experiments There are many studies. Previously, seaweed fiber production was mostly concentrated at the pilot level, and there was no systematic research and development in biomedical and textile clothing applications. Thirdly, the preparation efficiency of seaweed fiber spinning solution is low, and the traditional wet spinning process is used. The spinning solution is prepared in a small material tank. This method is more efficient in processing low-viscosity solutions, but it cannot be applied to the preparation and processing of high-viscosity solutions. �。</sect

In view of the above technical bottlenecks, the scientific research team led by Xia Yanzhi actively tackled the key problems and achieved the testing, screening and control of the structure of spinning raw materials through independently developed structural testing technology, and formulated fiber-grade sodium alginate production standards specifically for the preparation of seaweed fibers. The product specifications, requirements, test methods, inspection rules, marking, packaging, transportation and storage standards of fiber-grade sodium alginate are provided, providing sufficient technical indicators and effective production parameters for the production of fiber-grade sodium alginate. ��
