Today, we briefly discuss the PLA fiber melt spinning production process.

Synthetic fibers have a relatively high proportion in textile fibers and are now widely used in industrial and agricultural production, apparel, household and other fields. However, most of their raw materials are derived from nonrenewable resources such as petroleum and coal, and are easily degraded after use Pollution, therefore, "green" fiber materials that can be degraded and regenerated become the research direction of synthetic fibers in the future. In recent years, with the local maturation of the polylactic acid (PLA) fiber polymerization process, it is considered as one of the most promising "green" fibers with good biodegradability and recyclability while having a core Moisture absorption, good UV and germicidal resistance, excellent flame retardancy, excellent resilience and drapability. PLA fiber POY-DT technology has become a major production direction of PLA fiber because of its simple process route, low cost and small pollution. After conventional equipment is properly reformed, it can be industrially produced.

PLA fiber development momentum should not be underestimated, through the above introduction, I believe we have a general understanding of PLA fiber melt spinning production process.
