< p > in 2013, there was a H7N9 avian influenza epidemic in some parts of China. A large number of live birds were slaughtered, resulting in a serious shortage of raw materials market. The white feather down from the original 280 yuan / kg has been soaring to 630 yuan / kg, and the price of goose down has exceeded 1000 yuan / kg. The shortage of high price goods has become the biggest pressure for the down related enterprises.

For the predicament of the down industry, it is the best policy to find a quality equivalent to the a href= "//m.pmae.cn/news/list.aspx Classid=101112107101" > down down /a > stable production instead of down textiles.

Less than p ago, the project "the key technology and industrialization of multifunctional high quality down textiles" has been completed by Zhejiang Sci-Tech University, Xiaoshan Xintang Street North swan feather products industry technology research center, Zhejiang North Swan Limited by Share Ltd, Rongsheng Formosa Petrochemical Co, Shangyu Hong Qiang color polyester Co., Ltd. and Zhejiang Valley Textile Co., Ltd., and has won the "textile light" science and technology two award in 2013. Project research has formed a set of technology from multi-function fiber preparation, fabric functional realization, high density anti weave fabric multi arm / jacquard coupling design and manufacture, down products design and industrialization, and promoted the pace of China's high-end feather products to the international market.

< p > according to the project leader Zhang Hongxia, Professor of Zhejiang Sci-Tech University, the key technology and industrialization of multifunctional high-grade down textiles are combined with nano technology, composite spinning technology and implosion spinning technology. We have developed modified polyester filament which can release negative oxygen ions for a long time and emit far infrared rays, and honeycomb microporous polyester staple fibers with antibacterial and anti mite and quick moisture permeability and moisture permeability.

The structure has many functions, such as softness, anti pilling, moisture absorption, quick drying, cationic dyeing at room temperature and normal pressure. Moreover, its powerful function is suitable for all kinds of short fiber blending (white spinning and dyed spinning). It can still maintain its performance. After dyeing and finishing and high temperature setting 180 to 190 degrees C, it can overcome the defects of conventional polyester staple fiber products such as setting fastness, < a href= "//m.pmae.cn/news/list.aspx Classid=101112107108" > sublime fastness < /a >, polyester heat pfer dyeing, so as to achieve the permanent, environmental protection, wide use of the function, excellent safety and high technology content and high added value requirements.
