During the outbreak of the new crown epidemic, industrial textiles such as masks, protective clothing, and disinfectant wipes have become "essential weapons" to fight the epidemic. Geosynthetic materials are the infrastructure "contributors" to Vulcan Hill Hospital and Thunder Mountain Hospital The importance and indispensability of the industrial textile industry. The concept of "industrial textiles" was put forward in 1984. After more than 30 years of development, industrial textiles can now be said to be ubiquitous in our lives. In your opinion, what role did industrial textiles play in this epidemic?

Jin Xiangyu:

The outbreak of the new crown epidemic is difficult to develop targeted vaccines and drugs in a short period of time. Masks, protective clothing, including disinfectant wipes, nonwoven products for personal protection have played a key role. Adult protective masks and child protective masks can filter the air entering the mouth and nose to achieve the purpose of filtering the particulate matter in the harmful gases from entering and leaving the wearer's mouth and nose; protective clothing and isolation clothing allow medical personnel to isolate when they come in contact with infectious disease patients The patient's body fluids and viruses and bacteria in the air; disinfection wipes have a cleansing and disinfecting effect on the hands, skin or surface of objects, thus protecting the personal health of the people. These non-woven personal protection products, as the main tools for the public and frontline medical personnel to protect against viruses, provide an important line of defense against the epidemic for the general public.

Geosynthetics also helped the “China Speed” construction of Vulcan and Raytheon hospitals in Hubei, China, and played an important role in anti-seepage, drainage, and isolation.

Xie Jingwei:

Masks are used for respiratory protection, effectively blocking the spread of viruses through breathing, and are undoubtedly the necessary weapons to win the anti-epidemic resistance battle.

TA Weekly:

In the early stage of the outbreak, China's masks and protective clothing were once in a hurry and could not meet the needs of hospitals and the people. Please analyze the reasons.

Jin Xiangyu:

China is the largest country in the production of masks. In 2019, the total output of our masks exceeded 5 billion, accounting for more than 55% of the global production capacity, of which 70% was used for export. Before the epidemic, the average daily output of various types of masks in China was about 22 million pieces, of which the capacity of medical surgical masks was 2.2 million pieces / day, the production capacity of medical KN95 masks was about 600,000 pieces / day, and the others were used for large-scale civil protection , Industrial dustproof masks. After the outbreak of the new coronary pneumonia epidemic, the demand for masks surged, and even exporting to domestic sales was not enough.
