How does meltblown nonwovens move towards new application areas and the next development of meltblown nonwovens in the current economic situation

Meltblown non-woven fabric technology has been introduced into my country in only a few decades. my country has introduced meltblown production lines since the 1990s. Eighteen years ago, a foreign SMS online composite production line was introduced. Due to the high purchase price of equipment and high production and operation costs, the price of melt blown products is high, coupled with insufficient understanding of product performance and use, the melt blown market has not been able to open for a long time, and related enterprises are struggling and operating bleakly. In the fight against SARS, meltblown and SMS non-woven fabrics demonstrated excellent protection and isolation functions, gained renewed recognition and favor from the market, and led to a round of large expansion. In recent years, with the continuous development of meltblown technology, the application of meltblown non-woven fabrics is also expanding and extending to more fields. my country is a major producer of spunbonded meltblown non-woven fabrics, and the actual output of spunbonded meltblown non-woven fabrics is about 2 million tons per year. Five years ago, the actual output of spunmelt nonwovens in the industry reached 1.91 million tons, an increase of 15.42% over the previous year. Among them, the output of spunbond nonwovens accounts for 98% of the output of the entire spunmelt industry, and the output of meltblown nonwovens accounts for only 2.05%. The main reason for the slow growth in the output of meltblown non-woven fabrics is that the application range is relatively narrow and the product types are relatively single. However, the special properties of meltblown non-woven fabrics are irreplaceable in some applications. my country's meltblown products are mainly used in market fields such as isolation protection, filtration separation, heat insulation and sound insulation, oil-absorbing materials, and battery separators. Whether the application field of meltblown nonwovens can be further expanded, the answer is yes. After visiting Beijing Baostelun Company and listening to the introduction of the company's person in charge, we seemed to have the answer to break the bottleneck of meltblown non-woven applications. Hou Muyi, general manager of the company, said that in foreign countries, meltblown products have a wide range of applications, ranging from industrial fields to small homes and people’s lives. Meltblown materials are well-used in many fields. For example, sound-absorbing materials for home theaters, cabin partitions for motorboats, sound-absorbing materials for high-speed rail, and thermal insulation materials for buildings. 'Now, our company produces meltblown sound-absorbing materials for domestic automobile manufacturers such as Chery, and processes products on their behalf. Compared with the traditional recycled textile felt, this kind of meltblown sound-absorbing material has the characteristics of light weight, low combustion, environmental protection and good sound absorption effect, and is welcomed by domestic automobile manufacturers. In addition, as a building thermal and sound insulation material, it has a lot of room for development. 'Hou said. It is understood that the current production of meltblown non-woven fabrics per day is about 2 tons, and the annual output is about 400 tons, which has become the company's new profit growth point. According to statistics from the Spunbond Nonwovens Subcommittee, four years ago, the production situation in the meltblown industry was good, and the production capacity and output of meltblown nonwovens increased significantly over the previous year. In particular, the production of meltblown nonwovens is inextricably linked to public events, which has accelerated the growth rate of the industry. For example, the bird flu restricts poultry breeding, and the amount of down is small and the price is high. Meltblown/three-dimensional crimped polyester staple fiber composite thermal insulation cotton used for bedding and clothing came into being. With the outbreak of Ebola, the demand for barrier filter materials has increased. In recent years, the control of smog has received national attention and widespread social attention. The demand for mask cloth, air filtration materials, sewage treatment materials and other products has continued to expand, and the amount of use has increased, which has promoted the growth of meltblown industry output and the expansion of application fields. Currently, this trend is still developing. In the future, my country's economic development will enter a'new normal'. The model of purely pursuing GDP development by consuming a lot of energy has been abandoned and replaced by an innovation-driven development model. At present, my country’s melt-blown non-woven fabric enterprises have the most advanced melt-blown non-woven fabric production equipment in the world. Some key technologies, such as the hanger fluid design of the melt-blown die and the production of spinnerets, have The distance to foreign countries is shortening. Companies such as Tianjin TEDA, Fujian Kangjie, Fujian and Handan Hengyong have introduced the most advanced equipment in the world in recent years. A number of results have been achieved in the development of domestic meltblown equipment, such as meltblown/short fiber online composite equipment has been applied; meltblown pitch-based carbon fiber precursor and nano-level PLA high-end filter materials are also under development. I believe that with the unremitting efforts of workers in the meltblown industry in our country, the level of meltblown production technology will continue to be improved, the product application field will continue to expand, and the breakthrough of bottlenecks is just around the corner.
