Description

Technical Field

[0002] In the process of globalization, the transnational flow of production factors such as capital and technology has triggered changes in the regional structure of textile production worldwide, with production capacity rapidly concentrating in regions with labor cost advantages. For a long time, pure cotton products and cotton-polyester (synthetic fiber) products have dominated the textile market. However, with the reduction of arable land and the increasing scarcity of cotton resources, blends of synthetic fibers and regenerated cellulose fibers with cotton are gradually increasing in quantity and proportion. With the rapid development of my country's economy, the industrial structure of my country's textile industry is also constantly evolving, and the center of industrial focus is shifting. my country no longer possesses a labor cost advantage, and the Chinese government and people are increasingly focusing on the green, environmentally friendly, and sustainable development of the textile industry.
