Sinopec Yizheng Chemical Fibre Co Ltd, a subsidiary of Sinopec in Jiangsu Province, put its 12th meltblown non-woven fabric production lines into operation on May 9. Sinopec has now completed the construction of all its 16 meltblown non-woven fabric production lines to make materials for masks. After the full operation of the 16 production lines and together with Sinopec's joint venture enterprises that can produce seven tonnes of meltblown non-woven fabric every day, the daily production capacity of the company is expected to reach 37 tonnes, and its annual production capacity will exceed 13,500 tons, enough to make 13.5 billion medical face masks.
The meltblown non-woven fabric is the filtering layer in the middle part of the mask to absorb dust, bacteria and pollen. Faced with a market shortage of mask materials during the coronavirus outbreak, Sinopec decided to set up a total of 16 meltblown non-woven fabric production lines, with four in Sinopec Beijing Yanshan Petrochemical Co. and 12 in Sinopec Yizheng Chemical Fibre Limited. It took only 76 days to construct the world's largest meltblown non-woven fabric production base from the commencement on February 24 to full operation on May 9.
