New Material: Isatis Indigotica

It is incredible that putting the leaves on the body to achieve the function of resisting the pathogenic bacteria of cold. Recently, the first "medicine coat" made by Professor Hu Sheng, a professor of textile School of Qiingdao University, was made by a clothing company in Yushi village, Longquan street, Jimo City, Shandong province.

　　 Folium Isatidis fibre Accounting for 30%

The fabric from the leaves of Isatis indigotica is woven into cloth. The appearance of this special new cloth is no different from that of ordinary cloth and smells no special flavour. "This cloth is not ordinary cloth, it contains the extract of Folium Isatidis, it can resist many kinds of cold pathogens." Dan Xiuduo, general manager of clothing company, said the technology was developed jointly by the enterprise and the textile School of Qiingdao University. The leaves of Isatis indigotica leaves are extracted and woven into fabrics. After 10 more processes, they are made into underwear that can resist cold germs.

"At present, this technology is the most advanced in the world, and it is the first creation both at home and abroad." The staff of Jimo science and Technology Bureau said that at the end of last year, experts from the science and Technology Bureau organized special reviews on the results, and the experts agreed that the results reached the international leading level. In addition, the Chinese Academy of Sciences has also analyzed and tested the products. The products contain active ingredients of Folium Isatidis, and the antibacterial efficiency is high. "Tests show that after 50 times of washing, the antibacterial efficiency of the knitted fabric made from viscose fiber is still more than 99%." Yu Husheng introduced that the extract of Folium Isatidis knitted with viscose fiber of the Folium Isatidis can reach 30%.

Speaking of "medicine clothes", the head of the Jimo science and Technology Bureau said that this is a representative project with high technology content, which has been passed by the state technical department for examination and approval by the Jimo science and Technology Bureau. From the appearance, the cloth is the same as other fabrics, but the fabric is extracted from the leaves of Isatis indigotica Fort. After the first piece of "medicine coat" is made, it will open up a new field of knitting industry in Jimo. This underwear containing 30% isatis root can effectively inhibit many kinds of germs, and the next step will be the main baby underwear.

　　 3 years behind the scenes

According to Hu Sheng, from research to production, it took about 3 years. These are the substances extracted from the leaves of Isatis indigotica, which is known as the leaf of Isatis indigotica, which contains some antibacterial components such as glycosides, ketones, organic acids, etc. we add them into pure viscose spinning liquid by special technology, and weave the fibers with antibacterial effect, and then blend the fibers into yarn and make them into knitted products. According to Hu Sheng, the extract of Isatis indigotica leaves is yellow brown powder and smells of Chinese medicine. The knitted garments made from the extract have obvious bacteriostatic effects on Staphylococcus aureus, Escherichia coli and Candida albicans.

"Before that, some socks and underpants have been developed." Yu Husheng said that since the beginning of this year, through the cooperation with enterprises, fiber cloth has been extracted from the leaves of Isatis indigotica, and a small amount of socks and underpants have been made experimentally. After repeated tests, it is found that this kind of socks has good effect against foot odor. Moreover, socks and underwear made of this cloth are softer and more flexible than ordinary cloth, and have strong elasticity.

according to Shan Shu Du Introduce, consider this kind of cloth Therefore, next step, they will focus on the development and production of infant underwear. It is expected that this new "medicine coat" will be on sale in two months. In terms of price, Dan Xiuduo said that although the price of this kind of underwear is not yet conclusive, it will be a little higher than the price of ordinary underwear, but it will not be too high.

　　 Research aimed at industrialization.

"I started the invention research in 2011, and after 3 years of hard work, I developed it successfully, because the technology content is relatively high, so some data need to be repeatedly demonstrated before entering the actual production. Its characteristic is antibacterial and deodorant. Hu Sheng said that this kind of clothes can resist Candida albicans, Escherichia coli and Staphylococcus aureus, and it has been verified by experts that washing liquid can not be weakened within 54 times.

Hu Sheng said that the special fiber material extracted from the leaves of Isatis indigotica had some characteristics besides antibacterial and deodorant. For example, there is no process of adding chemical substances in the process of Banlangen cloth, it is a natural cloth, and the Radix Isatidis has already had several natural colors, and does not need artificial dyeing, so it is more suitable for making close fitting underwear. The "medicine coat" completed in Jimo can resist Candida albicans, Escherichia coli and Staphylococcus aureus.

Hu explained that at present, their products already have invention patents. The production process is to extract natural plant ingredients from Isatis indigotica. Just like decocting Chinese medicine, it extracts its soup, and then evaporates and leaves behind the leaves of indigotica leaves. Then it is blended into cotton fabrics by glue, and is combined into 10 by filtering and drying. The process is our patent, and there are many technologies in it. The cotton fabric blended into one is drawn into cotton yarn, then woven into cloth, and then processed into clothing. China's Shanxi and Shaanxi provinces are big producers of Isatis indigotica, so the raw materials of this new cloth are very abundant.

"At present, this technology is the most advanced in the world." Wang Xinchang, chief of the patent division of Jimo science and Technology Bureau, said that as the basic industry of Jimo, the invention of the leaves of the root of Isatis indigotica settled in Jimo. It will also provide a new path for the breakthroughs of the textile industry in Jimo.
