This report is from China Textile News: "As the new crown pneumonia epidemic spreads around the world, the global personal protection and other epidemic prevention materials have been declared urgent due to factors such as rising demand, hoarding or abuse, and there is a "mask shortage" in many countries.

Under this circumstance, Anhui Yuanchen Environmental Protection Technology Co., Ltd. (hereinafter referred to as "Yuanchen Technology") quickly responded to this situation, with a scientific and long-term vision of the economic situation, and quickly formed a "meltblown fabric production line + nano film production line + mask/protective clothing production line + third-party testing services "The whole industrial chain. In response to the market demand, the company has made strategic adjustment and planned a 10,000 square meters plant in the first phase, while continuously increasing the investment in scientific research and introducing intelligent equipment, which will achieve a daily production capacity of 3 million masks, 20 tons each of meltblown cloth and nano-film materials, and 5 tons of nose strips after full production.

According to statistics, 50% of the global meltblown cloth production capacity is in China, while the domestic meltblown cloth industry as a whole presents a small and scattered situation, the quality of meltblown cloth varies, the production of meltblown cloth does not meet the medical standards, resulting in mask manufacturers can not buy qualified medical meltblown cloth, and whether the masks eventually worn by the public are qualified, it can be imagined.

The meltblown cloth produced by Yuanchen Technology meets the following standards.

(1)YY/T 0969-2013 "single-use medical masks" standard only stipulates that the bacterial filtration efficiency of masks is not less than 95%, and lacks the filtration efficiency requirements for particles and bacteria.

(2)YY0469-2011 "medical surgical mask" standard stipulates that the bacterial filtration efficiency of the mask is not less than 95%, and the filtration efficiency of non-oily particles is not less than 30%.

(3) GB2626-2006 "respiratory protective equipment self-priming anti-particulate respirator" standard with sodium chloride particles to detect N class filter elements, with DOP or oil particles of comparable nature to detect P class filter elements, for KN90, KN95, KN100 and KP90, KP95, KP100 labeling, the filtration efficiency is greater than or equal to 90%, 95% , 99.95%.

At the same time, Yuanchen Technology also participated in the development of the group standard for civil sanitary masks (T/CNTAC 55-2020, T/CNITA 09104-2020 "Civil Sanitary Mask") issued by China Textile Industry Federation and China Industrial Textile Industry Association.

In addition, for the meltblown fabric production equipment, Yuanchen Technology monitors the salt particulate filtration efficiency (PFE) and bacterial filtration efficiency (BFE) of meltblown fabric in real time during the production process to ensure that the meltblown fabric meets the testing standards, and the test results from third-party testing institutions show that the PFE reaches over 95% and the BFE reaches 99%, meeting the requirements of civil and medical masks.

Ltd., a wholly-owned subsidiary of Yuanchen Technology, urgently procured a full set of instruments for masks, protective clothing and other related testing projects and applied for expansion to assist the parent company to make significant breakthroughs in product development, process improvement, quality control and standard setting, and also to provide third-party testing services for the market.

Yuanchen Technology has been driving high-quality development by scientific and technological innovation, elevating the concept of innovation to a strategic level, fully respecting the value of innovation, continuously increasing investment in technology research and development, making breakthroughs in the development and application of new materials, and making significant achievements in medical meltblown fabric and nano film materials, which have played a positive role in alleviating the shortage of raw materials for masks.
