The development of spinning technology under the new crown epidemic

The outbreak and continuous spread of the new crown pneumonia epidemic has severely impacted the supply and demand order of the

 global personal protective products market. According to the British "Financial Times" report, the price of overseas meltblown

 nonwovens once soared more than 10 times. The domestic production capacity of meltblown nonwovens in 2019 is approximately 

66,000 tons. In order to meet the needs of the personal protective product market, the daily meltblown processing capacity has 

been increased from 200 tons to more than 1,000 tons. According to statistics, the current daily production capacity of domestic

rotective masks is about 500 million pieces, and the daily output of protective clothing can reach 1.5 million pieces.

 
As the domestic epidemic stabilizes, investment in the personal protective equipment market has gradually become rational, 
 
and some of the production capacity of masks and protective clothing has been transferred to exports. At present, the processing 
 
of personal protective products such as masks and protective clothing in my country is mostly in the low-tech and low-value-added 
 
links. After the epidemic, the industry's production capacity will eventually be adjusted, and the production order will return
 
 to normal. This is also the case for developed countries. The fundamental reason for hesitating to invest during the health 
 
incident.
 
 
	
	
 
 
	
	
	
 
Before the outbreak of the new crown epidemic, more than 80% of the personal protective products in the United States, Europe
 
 and other countries and regions relied on imports. When the epidemic hits, it is also possible to choose outsourcing channels
 
 for supply. For example, the protective clothing industry giant DuPont (DuPont), although the output of its conventional
 
 products has been adjusted to increase by 3 times during the epidemic, it still puts the research and development of new
 
 products that adapt to the development of the epidemic at the center, and the nano-grade filter material is the hybrid membrane
 
 (HMT) The product is launched in the personal protective filter market. In the short hundreds of days since the large-scale 
 
outbreak of the epidemic, nano-grade filter media, antibacterial filter materials, functional two-component spunbond nonwovens
 
 that can replace meltblown cloth, bio-based meltblown fiber filter media, and washable and repeatable The protective
 
 masks/respirators used have entered the market one after another. The grim reality of the epidemic also reflects that the R&D
 
 investment in spun-laid products cannot be ignored in the updating and upgrading of personal protective products and the
 
 improvement of epidemic response capabilities.
 
 
According to statistics, since the outbreak of the new crown epidemic in 2020, my country has produced about 80% of the world`s
 
 masks, but there is still a significant gap between domestic spunmelt technology and product levels and foreign countries, such
 
 as the Reicofil R5 series spunmelt equipment launched by Reifenhäuser in Germany , The unit production capacity of its spunbond
 
 equipment and meltblown equipment is 270 kg/(m · h), and the same type of domestic equipment is about 30% lower than that, so
 
 key components such as high-end Spinning Components and melt blow Wait for import. At present, the quality of domestic spunmelt
 
 fibers is uneven. During the epidemic, workshop-type meltblown equipment that can be purchased for 300,000 yuan in Jiangsu and
 
 Zhejiang also appeared in the mask market, and the technical environment needs to be improved. Although China has the world's
 
 largest production capacity for masks, the quality of the meltblown fibers used still has great room for improvement.
 
 Furthermore, there are still big deficiencies in the R&D investment and technical reserves of personal protective materials,
 
 which require attention.
