During the novel coronavirus pneumonia, industrial textiles such as masks, protective clothing and disinfectant wipes became "the necessary weapons" to fight the epidemic. Geosynthetics were the "Heroes" of the foundation of the God of fire hospital and Raytheon hill hospital. Since the concept of "industrial textiles" was put forward in 1984, after more than 30 years of development, industrial textiles have been ubiquitous in our lives, and this epidemic shows the importance and indispensability of industrial textiles industry.
Reserve mechanism of protective emergency materials
Jin Xiangyu, Professor of Donghua University and deputy director of industrial textiles research center of the Ministry of education, told reporters that personal protective products such as masks, protective clothing and disinfectant wipes will still play a key role because it is difficult to develop targeted vaccines and drugs in the short term. Non woven personal protective products, such as adult protective masks, child protective masks, protective clothing, isolation clothes and disinfectant wipes, are the main anti epidemic tools for the public and front-line medical staff, and are an important defense line for the masses to fight against the epidemic. During the epidemic period, geosynthetics also played an important role in the construction of huoshenshan and leishenshan hospitals in Hubei Province.
Hu Guangmin, chairman of haisimore Biotechnology Co., Ltd., said that after the outbreak of the epidemic, the supply of masks and protective clothing was insufficient. In addition to some objective factors, the industry chain mechanism needs to be further improved, which is a topic that the industry needs to tackle at present and in the future. In this case, the mask production encountered the problem of shortage of meltblown cloth.
In this regard, one is to constantly improve the conventional production mechanism of the industrial chain, which is the foundation; The second is to establish a mechanism to deal with emergencies, including standards, detection, data statistics and so on. In case of emergency, key enterprises can respond quickly. For example, in this epidemic, some central enterprises and backbone private enterprises have played such a role; Third, from the government level, we should establish a reserve system and a diversified and flexible market mechanism.
"This epidemic has led to great fluctuations in the prices of masks from raw materials to equipment and then to products, which reflects the imperfections of the market mechanism. When problems arise, it is not a mature performance to rely solely on the government's punishment and fines to curb them. " Hu Guangmin suggested that the reserve of emergency materials such as masks and medical protective clothing should be improved, and a hierarchical reserve system for central, local and key enterprises should be established. once the market supply and production capacity change, the reserve system can respond.
Strengthening technology research and development to promote industrial chain integration
"The inner environment of the protective clothing is almost airtight. Although it has a certain moisture permeability, wearing it for a long time, people's sweat is discharged, evaporated and condensed on the protective clothing fabric, which inevitably brings discomfort and inconvenience to the medical staff." Jin Xiangyu said that in view of these problems, protective textiles will be greatly improved in the future.
For example, positive pressure medical protective clothing can be used, that is, the protective clothing itself carries fans, batteries and filter units, through which virus-free air can be delivered to the protective clothing. This can not only greatly improve the safety of the protective clothing, but also provide fresh air for the wearer to breathe, take away heat and water vapor, reduce the occurrence of fog, and improve the wearing comfort. To facilitate communication, it can also be equipped with intelligent equipment, such as Bluetooth, walkie talkie, etc.
In fact, whether it is masks or protective clothing, air tightness is the performance of large internal and external pressure difference. Domestic leading enterprises have been committed to the research of new materials, new processes and new technologies. Xie Jingwei, deputy general manager of Tianjin TEDA clean materials Co., Ltd., said that TEDA clean has recently achieved breakthroughs in superfine fiber structure, electret technology innovation and material composite technology“ In the future, protective textiles should also integrate industrial forces, integrate R & D projects, create national brands, promote the integration of upstream and downstream industrial chains, form industrial clusters, and improve rapid response capability.
