Polylactic acid fiber (PLA staple fiber), a fiber in the polyester family, whose raw materials are derived from plants such as corn and cassava. The production process is non-polluting and biodegradable. It is an environmentally friendly green material that can replace petroleum-based fibers. As early as the 1990s, China and the United States began to develop and produce polylactic acid fiber. However, due to factors such as high production costs, there has been no major development in the later period.

Now with the deepening of domestic research, the manufacturing cost of polylactic acid slicing is greatly reduced, and the price of PLA staple fiber made by it is greatly reduced, which means that the application of this green environmentally friendly material in the textile industry may usher in great opportunities. It will help the textile industry to achieve sustainable development.

Although PLA staple fiber is not a new fiber, it has ushered in a new historical starting point. Under the current situation of accelerating the green transformation and upgrading of manufacturing industry and promoting the efficient recycling of resources, the application of this green environmental protection material has far-reaching significance.

First, the important trend of current fiber materials is biomass, which includes the meaning of renewable, degradable, low-carbon three layers, and PLA staple fibers fully meet these three points. Among the textile raw materials, the higher the proportion is chemical fiber, and the higher the chemical fiber is polyester. Therefore, in order to realize the bio-chemicalization of chemical fiber in the future, polylactic acid fiber should gradually replace polyester and lead the bio-materials to realize biomass. .

The second is to solve the application problem of polylactic acid fiber. At present, the big problem of polylactic acid fiber is that the heat resistance is poor, and this problem is bound to impose greater requirements on the polymerization, and will also affect the application range of the product. At the same time, PLA staple fiber also has problems such as insufficient long-term stability and lack of product performance and processing temperature sensitivity. It is necessary to further modify existing materials to meet current market demands.

The third is to solve problems while developing, to push back product development according to market demand, and constantly explore and develop more new products.

The fourth is to strengthen the production, study and research, strengthen the upstream and downstream alliance, give full play to the market-oriented role, and use the advantages of PLA staple fiber to guide the market.
