For the pollution problem in China’s textile and garment industry, the author particularly analyzes the pollution of the textile and garment industry mainly occurred in the process of textile and clothing production and sales in this article. Finally, the author puts forward detail measure to control the pollution from the two aspects and advocates the concept of low-carbon environmental protection and green lifestyle. The low-carbon environmental protection has become a phenomenon in Textile and Apparel.展开更多
