The research and application development of PLA staple fibers in the textile field has begun in recent years. The polylactic acid can be directly formed into a nonwoven fabric by a spunbonding method or a melt-blown method, or can be first spun into a PLA staple fiber, and then obtained by a dry method or a wet method to obtain a nonwoven fabric.

PLA staple fiber non-woven fabrics are used in agriculture and horticulture for seed cultivation, breeding, frost protection and weeding cloth. In medical and health applications, they can be used as surgical gowns, surgical coverings, masks, etc. For diapers, fabrics for women's sanitary napkins and other sanitary products; in the case of daily necessities, can be used as clothing, wipes, kitchen water, filter bags or other packaging materials.

From this point of view, the application field of PLA staple fiber is beyond imagination, and as the research progresses, more functions will be gradually developed.
