The "Key Preparation Technology and Industrialization of New Meltblown Nonwoven Materials" project jointly completed by Tianjin Polytechnic University, Tianjin TEDA Clean Materials Co., Ltd. and the Military Equipment Research Institute of the General Logistics Department of the Chinese People's Liberation Army was awarded the National Science Research Institute on January 9. Second prize for technological progress.

The project has made a major breakthrough in the key preparation technology of new meltblown nonwoven materials, formed a number of core technologies, developed a variety of new meltblown nonwoven products, and built the first two-component meltblown production line in China. Industrialization has achieved good economic and social benefits, and has improved the overall level of the nonwoven industry.

Melt-blown non-woven technology is an important means for the efficient production and processing of industrial textiles. The process flow is short and the production efficiency is high. Its products have the characteristics of ultra-fine fibers, large specific surface area, and high porosity. Influenza, etc.), thermal insulation, high temperature protection, high temperature insulation, sound absorption and noise reduction have unique advantages. The new meltblown nonwoven materials are widely used in high-efficiency filtration, medical and health protection, automobile sound insulation, military warmth and other fields, and the products are sold to Europe and the United States. It has played an active role in major public emergencies such as SARS and H1N1; a series of thermal insulation materials have been equipped with the entire army, and the cumulative output value of military uniforms alone has reached 1.457 billion yuan. Under the conditions of equivalent thermal insulation, the weight of the entire set of clothing can be reduced by 3 kg , The thickness is reduced by 3 cm, which greatly improves the individual maneuverability of our army; the wide-width meltblown equipment breaks the foreign monopoly, and the equipment is sold to Turkey, Argentina, and Saudi Arabia.
