As of 2018, the number of production lines of melt-blown sound-absorbing materials nationwide has reached more than 60, and nearly 30 companies have produced them. The application of sound-absorbing materials in the automotive field has now become a larger application market in the field of meltblown. In 2009, during the H1N1 epidemic in Jialiu, domestic melt-blown production lines were successively launched. At that time, the 'heart' of the masks should be melt-blown, and many mask manufacturers did not have the concept of level. After the H1N1 incident, the application of melt-blown non-woven fabrics in the field of masks dropped to the freezing point, and the operating rate was generally within 50%.

It took 3 years for the filter materials of melt-blown masks to recover slightly. After that, the melt-blown mask filter material has been producing capacity during the period of digesting the epidemic, and has been put into production in a small circle. From 2010 to 2018, including Jiangyin, Zhangjiagang, Kunshan and other southern regions, Hubei Xiantao, Subei Suqian, and Tongcheng, Anhui, more than 10 production lines were put into operation in the spontaneous market. At the end of 2015, Jiangxi Tianlu put into production its first production line, which filled the gap of meltblown in Jiangxi Province. At the beginning of 2015, the broadcast of 'Chai Jing Haze Survey: Under the Dome' let hundreds of millions of people know the hazards of haze, and it directly gave birth to an application field of 'haze mask'. The large number of applications of air purifiers has made more purifier manufacturers directly involved in the field of meltblown. From 2015 to 2018,China Textile,

Tianjin TEDA, Shandong Junfu, Handan Hengyong and other companies entered the field of high efficiency and low resistance. Jiangsu Yimao, Shanghai Mingguan, Zhejiang Jinhai, Shaanxi Keda and other companies have also gradually launched this period. A 1.6-meter-wide meltblown production line was launched. Table 2:

Distribution of enterprises in China's meltblown nonwoven application market in 2019 Under the concept of smog, the meltblown industry has also been rapidly stimulated. In 2019, the melt-blown cloth in the field of air purifiers will have a feather. Remember a small episode, the 'quenching' of the air purification field, let China Textile and Chongqing Zaisheng in the profit-to-betting agreement, the founder team directly lost the company's controlling stake,
