China is a world leader in textiles with nearly 60 million tonnes of fiber per year. Commonly used fibers are cotton, silk, synthetic fibers and algae fibers. The traditional method of stripping can not produce thin fabrics for clothing, which can only be used for medical textiles such as tapes.

A new yarn extraction method allows for much stronger fibers, co-authored by the new Textile Materials and Materials Laboratory of Qingdao University and the Qingdao Xiyingmen Group, one of the leading companies. on Chinese textiles. This technology was developed in 2007 with a variety of algae in which the anginate fibers are extracted. Due to the significant toughness, especially fire resistance and electromagnetic waves, these fibers have been used to produce protective clothing for firefighters or medical personnel.
The yarn is highly durable, extracted from algae that are considered dangerous to wildlife and marine life, such as brown algae and green algae that have recently invaded the coast of China. Thus, it can turn harmful algae into a valuable and environmentally beneficial resource. China is the world's leading producer of algae. In 2009, 77% of global renewable fiber production, or 1.91 million tons, was produced in China.
Qingdao Xiyingmen Group believes that the mass production of yarn under this technology will be made in 2011. With current technology, 200 kg of anthracite yarn is extracted from one ton of dry algae at a production cost of 50 to 70,000 yuan / ton yarn.
