Using the natural polymer material of chitin as raw material, Shizhan Technology Co., Ltd., which is well-known in the domestic biotechnology and medical industry, officially produced the basic raw material of water-soluble chitin in 2001 and launched the application of chitin. In recent years, the medical and health care textiles which have been successfully developed against "super bacteria MRSA" have passed the US patent (Patent Pub. No. US2014/0034181 A1).

Qiu Minghong, general manager of Shizhan Technology Co., said that in order to improve and purify the living environment and prevent the spread of various germs in medical institutions, Qiu Minghong said that one of the countermeasures is the medical textiles of hospitals such as bed sheets in hospital wards. The use of antibacterial textiles such as MRSA, such as MRSA, is used in the treatment of chronic diseases such as diapers, hair towels, and medical staff's uniforms or long-term care institutions.

It is worth mentioning that Shizhan Technology Water-soluble Chitin has won the 2001 National Biomedical Medical Quality Award. In 2012, it also penetrated into the medical textile field with anti-MRSA (super bacteria). Its antibacterial function is similar to silver ion (NH3, amine-based positive electricity), which can produce medical grade antibacterial cloth and antibacterial clothes, and has long-lasting natural antibacterial benefits.

In recent years, we have cooperated with Taiwan Chemical Technology, using nano technology, adding chitin raw materials (antibacterial agents) to the slime, and successfully launching SETOSAN Rayon through spinning and cotton cutting, which is the first brand in China. Natural chitin antibacterial fiber. In 2011, Shizhan Technology entered the field of home textiles, using “nano particle technology” to produce home-made antibacterial products such as wool bath towels, underwear, socks, etc., which are registered trademarks of “Jes Jieshida”, which is regulated by Jieshida Company. Painting marketing, sold in domestic Mei'an and internal medicine websites.
